I have a table and it has a 3 columns. The first column is the data that contains value(numeric) and unit(percentage and etc..), the second column is numeric column, the third is Unit column. What I want to do is split the numeric and the unit from the first column then put those split-ted data to its designated column.
Here is my table:
I tried this function:SO link here..., it really does splitting alpha and numeric but then I'm new in using SQL Function, my problem there is the parameter must be in string STRING, so what I did is change it to Sub Query but it gives me error.
Sample COde:
SQL FUNCTION:
create function [dbo].[GetNumbersFromText](#String varchar(2000))
returns table as return
(
with C as
(
select cast(substring(S.Value, S1.Pos, S2.L) as int) as Number,
stuff(s.Value, 1, S1.Pos + S2.L, '') as Value
from (select #String+' ') as S(Value)
cross apply (select patindex('%[0-9]%', S.Value)) as S1(Pos)
cross apply (select patindex('%[^0-9]%', stuff(S.Value, 1, S1.Pos, ''))) as S2(L)
union all
select cast(substring(S.Value, S1.Pos, S2.L) as int),
stuff(S.Value, 1, S1.Pos + S2.L, '')
from C as S
cross apply (select patindex('%[0-9]%', S.Value)) as S1(Pos)
cross apply (select patindex('%[^0-9]%', stuff(S.Value, 1, S1.Pos, ''))) as S2(L)
where patindex('%[0-9]%', S.Value) > 0
)
select Number
from C
)
SELECT STATEMENT with SUB Query:
declare #S varchar(max)
select number from GetNumbersFromText(Select SomeColm From Table_Name) option (maxrecursion 0)
BTW, im using sql server 2005.
Thanks!
If the numeric part is always at the beginning, then you can use this:
PATINDEX('%[0-9][^0-9]%', ConcUnit)
to get the index of the last digit.
Thus, this:
DECLARE #str VARCHAR(MAX) = '4000 ug/ML'
SELECT LEFT(#str, PATINDEX('%[0-9][^0-9]%', #str )) AS Number,
LTRIM(RIGHT(#str, LEN(#str) - PATINDEX('%[0-9][^0-9]%', #str ))) As Unit
gives you:
Number Unit
-------------
4000 ug/ML
EDIT:
If numeric data include double values as well, then you can use this:
SELECT LEN(#str) - PATINDEX ('%[^0-9][0-9]%', REVERSE(#str))
to get the index of the last digit.
Thus, this:
SELECT LEFT(#str, LEN(#str) - PATINDEX ('%[^0-9][0-9]%', REVERSE(#str)))
gives you the numeric part.
And this:
SELECT LEFT(#str, LEN(#str) - PATINDEX ('%[^0-9][0-9]%', REVERSE(#str))) AS Numeric,
CASE
WHEN CHARINDEX ('%', #str) <> 0 THEN LTRIM(RIGHT(#str, LEN(#str) - CHARINDEX ('%', #str)))
ELSE LTRIM(RIGHT(#str, PATINDEX ('%[^0-9][0-9]%', REVERSE(#str))))
END AS Unit
gives you both numberic and unit part.
Here are some tests that I made with the data you have posted:
Input:
DECLARE #str VARCHAR(MAX) = '50 000ug/ML'
Output:
Numeric Unit
------------
50 000 ug/ML
Input:
DECLARE #str VARCHAR(MAX) = '99.5%'
Output:
Numeric Unit
------------
99.5
Input:
DECLARE #str VARCHAR(MAX) = '4000 . 35 % ug/ML'
Output:
Numeric Unit
------------------
4000 . 35 ug/ML

Would something like this work? Based on the shown data it looks like it would.
Apply it to your data set as a select and if you like the results then you can make an update from it.
WITH cte as (SELECT 'ug/mL' ConcUnit, 500 as [Numeric], '' as Unit
UNION ALL SELECT '2000 ug/mL', NULL, '')
SELECT
[ConcUnit] as [ConcUnit],
[Numeric] as [Original Numeric],
[Unit] as [Original Unit],
CASE WHEN ConcUnit LIKE '% %' THEN
SUBSTRING(ConcUnit, 1, CHARINDEX(' ', ConcUnit) - 1)
ELSE [Numeric] END as [New Numeric],
CASE WHEN ConcUnit LIKE '% %'
THEN SUBSTRING(ConcUnit, CHARINDEX(' ', ConcUnit) + 1, LEN(ConcUnit))
ELSE ConcUnit END as [New Unit]
FROM cte
change #concunit & #unitx Respectively
DECLARE #concunit varchar(10)='45.5%'
DECLARE #unitx varchar(10)='%'
BEGIN
SELECT RTRIM(SUBSTRING( #concunit , 1 , CHARINDEX( #unitx , #concunit
) - 1
)) AS Number,
RTRIM(SUBSTRING( #concunit , CHARINDEX( #unitx , #concunit
) , LEN( #concunit
) - (CHARINDEX( #unitx , #concunit
) - 1)
)) AS Unit
end
I had the same dilemma, but in my case the alpha's were in front of the numerics.
So using the logic that #Giorgos Betsos added to his answer, I just reversed it.
I.e., when your input is :
abc123
You can split it like this:
declare #input varchar(30) = 'abc123'
select
replace(#input,reverse(LEFT(reverse(#input), PATINDEX('%[0-9][^0-9]%', reverse(#input) ))),'') Alpha
, reverse(LEFT(reverse(#input), PATINDEX('%[0-9][^0-9]%', reverse(#input) ))) Numeric
Results :
I am involved in a data migration project. I am getting the following error when I try to insert data from one table into another table (SQL Server 2005):
Msg 8152, Level 16, State 13, Line 1
String or binary data would be truncated.
The source data columns match the data type and are within the length definitions of the destination table columns so I am at a loss as to what could be causing this error.
You will need to post the table definitions for the source and destination tables for us to figure out where the issue is but the bottom line is that one of your columns in the source table is bigger than your destination columns. It could be that you are changing formats in a way you were not aware of. The database model you are moving from is important in figuring that out as well.
As others have already said, one of your columns datatypes in the source table is larger than your destination columns.
A simple solution is to turn off the warning and allow truncation to take place. So, if you're receiving this error but you are sure it is acceptable for data in your old database/table to be truncated (cut to size) you can simply do the following;
SET ANSI_WARNINGS OFF;
-- Your insert TSQL here.
SET ANSI_WARNINGS ON;
As above, always remember to turn warnings back on again afterwards.
The issue is quite simple: one or more of the columns in the source query contains data that exceeds the length of its destination column. A simple solution would be to take your source query and execute Max(Len( source col )) on each column. I.e.,
Select Max(Len(TextCol1))
, Max(Len(TextCol2))
, Max(Len(TextCol3))
, ...
From ...
Then compare those lengths to the data type lengths in your destination table. At least one, exceeds its destination column length.
If you are absolutely positive that this should not be the case and do not care if it is not the case, then another solution is to forcibly cast the source query columns to their destination length (which will truncate any data that is too long):
Select Cast(TextCol1 As varchar(...))
, Cast(TextCol2 As varchar(...))
, Cast(TextCol3 As varchar(...))
, ...
From ...
SQL Server 2019 will finally return more meaningful error message.
Binary or string data would be truncated => error message enhancments
if you have that error (in production), it's not obvious to see which column or row this error comes from, and how to locate it exactly.
To enable new behavior you need to use DBCC TRACEON(460). New error text from sys.messages:
SELECT * FROM sys.messages WHERE message_id = 2628
2628 – String or binary data would be truncated in table ‘%.*ls’, column ‘%.*ls’. Truncated value: ‘%.*ls’.
String or Binary data would be truncated: replacing the infamous error 8152
This new message is also backported to SQL Server 2017 CU12 (and in an upcoming SQL Server 2016 SP2 CU), but not by default. You need to enable trace flag 460 to replace message ID 8152 with 2628, either at the session or server level.
Note that for now, even in SQL Server 2019 CTP 2.0 the same trace flag 460 needs to be enabled. In a future SQL Server 2019 release, message 2628 will replace message 8152 by default.
SQL Server 2017 CU12 also supports this feature.
Improvement: Optional replacement for "String or binary data would be truncated" message with extended information in SQL Server 2017
This SQL Server 2017 update introduces an optional message that contains the following additional context information.
Msg 2628, Level 16, State 6, Procedure ProcedureName, Line Linenumber
String or binary data would be truncated in table '%.*ls', column '%.*ls'.
Truncated value: '%.*ls'.
The new message ID is 2628. This message replaces message 8152 in any error output if trace flag 460 is enabled.
db<>fiddle demo
ALTER DATABASE SCOPED CONFIGURATION
VERBOSE_TRUNCATION_WARNINGS = { ON | OFF }
APPLIES TO: SQL Server (Starting with SQL Server 2019 (15.x)) and Azure SQL Database
Allows you to enable or disable the new String or binary data would be
truncated error message. SQL Server 2019 (15.x) introduces a new, more
specific error message (2628) for this scenario:
String or binary data would be truncated in table '%.*ls', column'%.*ls'. Truncated value: '%.*ls'.
When set to ON under database compatibility level 150, truncation
errors raise the new error message 2628 to provide more context and
simplify the troubleshooting process.
When set to OFF under database compatibility level 150, truncation
errors raise the previous error message 8152.
For database compatibility level 140 or lower, error message 2628
remains an opt-in error message that requires trace flag 460 to be
enabled, and this database scoped configuration has no effect.
One other potential reason for this is if you have a default value setup for a column that exceeds the length of the column. It appears someone fat fingered a column that had a length of 5 but the default value exceeded the length of 5. This drove me nuts as I was trying to understand why it wasn't working on any insert, even if all i was inserting was a single column with an integer of 1. Because the default value on the table schema had that violating default value it messed it all up - which I guess brings us to the lesson learned - avoid having tables with default value's in the schema. :)
Here is a slightly different answer. Your column names & lengths may all match, but perhaps you are specifying the columns in the wrong order in your SELECT statement. Say tableX and tableY have columns with the same name, but in different order
I am going to add one other possible cause of this error just because no one has mentioned it and it might help some future person (since the OP has found his answer). If the table you are inserting into has triggers, it could be the trigger is generating the error. I have seen this happen when table field definitions were changed, but audit tables were not.
If you’re on SQL Server 2016-2017:
to fix it, turn on trace flag 460
DBCC TRACEON(460, 1);
GO
and make sure you turn it off after:
DBCC TRACEOFF(460, 1);
GO
source
For the others, also check your stored procedure. In my case in my stored procedure CustomSearch I accidentally declared not enough length for my column, so when I entered a big data I received that error even though I have a big length on my database. I just changed the length of my column in my custom search the error goes away. This is just for the reminder. Thanks.
This can be a challenging error. Here are some notes taken from https://connect.microsoft.com/SQLServer/feedback/details/339410/ look for AmirCharania's comment.
I've adjusted the answer given by AmirCharania for data selected into an actual table, instead of a temp one. First select your dataset into a development table then run the following:
WITH CTE_Dev
AS (
SELECT C.column_id
,ColumnName = C.NAME
,C.max_length
,C.user_type_id
,C.precision
,C.scale
,DataTypeName = T.NAME
FROM sys.columns C
INNER JOIN sys.types T ON T.user_type_id = C.user_type_id
WHERE OBJECT_ID = OBJECT_ID('YOUR TARGET TABLE NAME HERE, WITH SCHEMA')
)
,CTE_Temp
AS (
SELECT C.column_id
,ColumnName = C.NAME
,C.max_length
,C.user_type_id
,C.precision
,C.scale
,DataTypeName = T.NAME
FROM sys.columns C
INNER JOIN sys.types T ON T.user_type_id = C.user_type_id
WHERE OBJECT_ID = OBJECT_ID('YOUR TEMP TABLE NAME HERE, WITH SCHEMA')
)
SELECT *
FROM CTE_Dev D
FULL OUTER JOIN CTE_Temp T ON D.ColumnName = T.ColumnName
WHERE ISNULL(D.max_length, 0) < ISNULL(T.max_length, 999)
Yes,I am also face these kind of problem.
REMARKS VARCHAR(500)
to
REMARKS VARCHAR(1000)
Here, I've change REMARKS filed length from 500 to 1000
Yep - "a pint into a half-pint pot will not go". I've not had much luck (for whatever reason) with the various SPs that folks have suggested, BUT as long as the two tables are in the same DB (or you can get them into the same DB), you can use INFORMATION_SCHEMA.COLUMNS to locate the errant field(s), thusly:
select c1.table_name,c1.COLUMN_NAME,c1.DATA_TYPE,c1.CHARACTER_MAXIMUM_LENGTH,c2.table_name,c2.COLUMN_NAME, c2.DATA_TYPE,c2.CHARACTER_MAXIMUM_LENGTH
from [INFORMATION_SCHEMA].[COLUMNS] c1
left join [INFORMATION_SCHEMA].[COLUMNS] c2 on
c1.COLUMN_NAME=c2.COLUMN_NAME
where c1.TABLE_NAME='MyTable1'
and c2.TABLE_NAME='MyTable2'
--and c1.DATA_TYPE<>c2.DATA_TYPE
--and c1.CHARACTER_MAXIMUM_LENGTH <> c2.CHARACTER_MAXIMUM_LENGTH
order by c1.COLUMN_NAME
This will let you scroll up and down, comparing field lengths as you go. The commented sections let you see (once uncommented, obviously) if there are data type mismatches, or specifically show those that differ in field length - cos I'm too lazy to scroll - just be aware that the whole thing is predicated on the source column names matching those of the target.
I came across this problem today, and in my search for an answer to this minimal informative error message i also found this link:
https://connect.microsoft.com/SQLServer/feedback/details/339410/please-fix-the-string-or-binary-data-would-be-truncated-message-to-give-the-column-name
So it seems microsoft has no plans to expand on error message anytime soon.
So i turned to other means.
I copied the errors to excel:
(1 row(s) affected)
(1 row(s) affected)
(1 row(s) affected)
Msg 8152, Level 16, State 14, Line 13
String or binary data would be truncated.
The statement has been terminated.
(1 row(s) affected)
counted the number of rows in excel, got to close to the records counter that caused the problem... adjusted my export code to print out the SQL close to it... then ran the 5 - 10 sql inserts around the problem sql and managed to pinpoint the problem one, see the string that was too long, increase size of that column and then big import file ran no problem.
Bit of a hack and a workaround, but when you left with very little choice you do what you can.
I was using empty string '' on on table creation and then receiving error 'Msg 8152, String or binary data would be truncated' on subsequent update. This was happening due to the update value containing 6 characters and being larger than the column definition anticipated. I used "SPACE" to get around this only because I knew I would be updating in bulk following the initial data creation i.e. the column was not going to remain empty for long.
SO BIG CAVEAT HERE: This is not a particularly slick solution but is useful in the case where you are pulling together a data set e.g. for one-off intelligence requests where you are creating a table for data mining, applying some bulk processing/interpretation and storing before and after results for later comparison/mining. This is a frequent occurrence in my line of work.
You can initially populate using the SPACE keyword i.e.
select
Table1.[column1]
,Table1.[column2]
,SPACE(10) as column_name
into table_you_are_creating
from Table1
where ...
Subsequent updates to "column_name" of 10 characters or less (substitute as applicable) will then be allowed without causing truncate error. Again, I would only use this in scenarios similar to that described in my caveat.

I wrote a useful store procedure to help identify and resolve the problem of text truncation (String or binary data would be truncated) when the INSERT SELECT statement is used. It compares fields CHAR, VARCHAR, NCHAR AND NVARCHAR only and returns an evaluation field by field in case of being the possible cause of the error.
EXEC dbo.GetFieldStringTruncate SourceTableName, TargetTableName
This stored procedure is oriented to the problem of text truncation when an INSERT SELECT statement is made.
The operation of this stored procedure depends on the user previously identifying the INSERT statement with the problem. Then inserting the source data into a global temporary table. The SELECT INTO statement is recommended.
You must use the same name of the field of the destination table in the alias of each field of the SELECT statement.
FUNCTION CODE:
DECLARE #strSQL nvarchar(1000)

For now only supports the data types CHAR, VARCHAR, NCHAR and NVARCHAR. You can find the last versión of this code in the next link below and we help each other to improve it. GetFieldStringTruncate.sql
https://gist.github.com/jotapardo/210e85338f87507742701aa9d41cc51d
Change the length of the data type nchar(10) to nchar(255) at least.
this can also happen when you dont have adequate permissions
I had a similar issue. I was copying data from one table to an identical table in everything but name.
Eventually I dumped the source table into a temp table using a SELECT INTO statement.
SELECT *
INTO TEMP_TABLE
FROM SOURCE_TABLE;
I compared the schema of the source table to temp table. I found one of the columns was a varchar(4000) when I was expecting a varchar(250).
UPDATE:
The varchar(4000) issue can be explained here in case you are interested:
For Nvarchar(Max) I am only getting 4000 characters in TSQL?
Hope this helps.
This error is thrown when the column of a table puts constraint [ mostly length ]. . E.g. if database schema for column myColumn is CHAR(2), then when your call from any of your application to insert value, you must pass String of length two.
The error basically says it; string of length three and above is inconsistent to fit the length restriction specified by database schema. That's why SQL Server warns and throws data loss/ Truncation error.
Please try the following code:
CREATE TABLE [dbo].[Department](
[Department_name] char(10) NULL
)
INSERT INTO [dbo].[Department]([Department_name]) VALUES ('Family Medicine')
--error will occur
ALTER TABLE [Department] ALTER COLUMN [Department_name] char(50)
INSERT INTO [dbo].[Department]([Department_name]) VALUES ('Family Medicine')
select * from [Department]
Faced the same.
The length of the column in source table was more than destination
source column length - 50 and
destination column length - nvarchar(25) and increased it to Nvarchar(50) and it worked
In Acumatica ERP I have gotten the same error during Import of order.
String or binary data would be truncated in table 'MyDatabase.dbo.ARInvoice', column 'InvoiceNbr'. Truncated value 'Something'.
After doing steps described in this link How to fix the error of String or Binary truncation, I got another error of "Quantity would become negative", which is solved by creating some quantity in Receipts screen.
I have a table with a nvarchar column. This column has values for example:
983
294
a343
a3546f
and so on.
I would like to take MAX of this values, but not as text but like from numerics. So in this example numerics are:
983
294
343
3546
And the MAX value is the last one - 3546. How to do this in TSQL on Microsoft SQL?
First install a regular expression function. This article has code you can cut/paste.
Then with RegexReplace (from that article) you can extract digits from a string:
dbo.RegexReplace( '.*?(\d+).*', myField, '$1' )
Then convert this string to a number:
CAST( dbo.RegexReplace( '.*?(\d+).*', myField, '$1' ) AS INT )
Then use this expression inside a MAX() function in a SELECT.
You can try to keep it simple without using Regular Expression
Here is the source
create table #t ( val varchar(100) )
insert #t select 983
insert #t select 294
insert #t select 'a343'
insert #t select 'a3546f';
GO
;with ValueRange as (
select val,
[from] = patindex('%[0-9]%', val),
[to] = case patindex('%[a-z]', val)
when 0 then len(val)
else patindex('%[a-z]', val) - patindex('%[0-9]%', val)
end
from #t
)
select substring(val, [from], [to]) as val
from ValueRange VR
order by cast(substring(val, [from], [to]) as int) desc
CAST() would do the trick, probably.
SELECT MAX(CAST(yourColumn AS int)) AS maxColumns FROM yourTable
Edit.
I didn't read the whole question, as it seems...
– Function to strip out non-numeric chars
ALTER FUNCTION dbo.UDF_ParseNumericChars
(
#string VARCHAR(8000)
)
RETURNS VARCHAR(8000)
AS
BEGIN
DECLARE #IncorrectCharLoc SMALLINT
–SET #IncorrectCharLoc = PATINDEX(’%[^0-9A-Za-z]%’, #string)
SET #IncorrectCharLoc = PATINDEX(’%[^0-9.]%’, #string)
WHILE #IncorrectCharLoc > 0
BEGIN
SET #string = STUFF(#string, #IncorrectCharLoc, 1, ”)
SET #IncorrectCharLoc = PATINDEX(’%[^0-9.]%’, #string)
END
SET #string = #string
RETURN #string
END
GO
I picked it from here. (I voted up the reg exp answer though)
you can write a function something like
create FUNCTION [dbo].[getFirstNumeric](
#s VARCHAR(50)
)
RETURNS int AS
BEGIN
set #s = substring(#s,patindex('%[0-9]%',#s),len(#s)-patindex('%[0-9]%',#s) + 1)
if patindex('%[^0-9]%',#s) = 0
return #s
set #s = substring(#s,1,patindex('%[^0-9]%',#s)-1)
return cast(#s as int)
end
and then call
select max(dbo.getFirstNumeric(yourColumn)) from yourTable
if you are using SQL Server 2005 or never you can also use the solution posted by Sung Meister
As far as I know you would need to create a process (or user defined function) to scrub the column, so that you can actually convert it to an INT or other appropriate datatype, then you can take the max of that.
By using user defined function parse the value to an int and then run the select.
SELECT MAX(dbo.parseVarcharToInt(column)) FROM table
SELECT dbo.RegexReplace('[^0-9]', '','a5453b',1, 1)
and RegexReplace installation like Jason Cohen said
This is an old question, I know - but to add to the knowledge base for others...
Assuming all your values have at least 1 number in them:
Select max(convert(int, SubString(VarName, PATINDEX('%[0-9]%',VarName), Len(VarName))))
from ATable
This is my simple answer. You can try it. But it works for fixed removable string value.
select max(cast(SUBSTRING(T.column,3,len(T.column)) as int)) from tablename T
