I have to get the count of specific word from the column in the table.
Example : assume this value is in the column:
uid-234,uid-342,uid-345
I need to retrieve the count as 3 by using T-SQL in SQL Server.
Try this, It should work
SELECT SUM(len(YourColumn) - len(replace(YourColumn, ',', '')) +1)
AS TotalCount
FROM YourTable
Try this,
DECLARE #Column VARCHAR(100) = 'uid-234,uid-342,uid-345'
SELECT len(#Column) - len(replace(#Column, ',', '')) + 1 AS TotalCount
You can try following code
select
*, (select count(*) from dbo.Split(concatenatedColumn,',')) cnt
from myTable
But you need to create the user defined function SPLIT string on your database first

If I have a table named dbo.cls_members in SQL server and there is a column named meb_refs containing reference numbers like the following
"A03LV4COOD17JE-SN1AM"
How do I find the records of the DISTINCT first character after the "-" symbol. ?
For example in the reference above the bold "S" after the "-".
Perhaps...
SELECT DISTINCT LEFT(STUFF([Column],1,CHARINDEX('-',[Column]),''),1)
FROM YourTable;
Run the following query:
SELECT DISTINCT
[Letter]
FROM
(
SELECT
column_name [Code] --Step One
,RIGHT(column_name, CHARINDEX('-', REVERSE(column_name))-1) [Part after -]
,LEFT(RIGHT(column_name, CHARINDEX('-', REVERSE(column_name))-1), 1) [Letter]
FROM table_name
) T
It's a simple as:
SELECT DISTINCT SUBSTRING(t.col, CHARINDEX('-',t.col)+1, 1)
FROM <yourtable> t;
Try this:
DECLARE #nar NVARCHAR(max) = 'A03LV4COOD17JE-SN1AM'
SELECT RIGHT(left(REVERSE(#nar), CHARINDEX('-',REVERSE(#nar))-1),1)
Alternatively, you can try:
SELECT * from table
where RIGHT(left(REVERSE(Columnname), CHARINDEX('-',REVERSE(Columnname))-1),1)
in ('S')
I have a question about SQL Server: I have a database column with a pattern which is like this:
up to 10 digits
then a comma
up to 10 digits
then a semicolon
e.g.
100000161, 100000031; 100000243, 100000021;
100000161, 100000031; 100000243, 100000021;
and I want to extract within the pattern the first digits (up to 10) (1.) and then a semicolon (4.)
(or, in other words, remove everything from the semicolon to the next semicolon)
100000161; 100000243; 100000161; 100000243;
Can you please advice me how to establish this in SQL Server? Im not very familiar with regex and therefore have no clue how to fix this.
Thanks,
Alex
Try this
Declare #Sql Table (SqlCol nvarchar(max))
INSERT INTO #Sql
SELECT'100000161,100000031;100000243,100000021;100000161,100000031;100000243,100000021;'
;WITH cte
AS (SELECT Row_number()
OVER(
ORDER BY (SELECT NULL)) AS Rno,
split.a.value('.', 'VARCHAR(1000)') AS Data
FROM (SELECT Cast('<S>'
+ Replace( Replace(sqlcol, ';', ','), ',',
'</S><S>')
+ '</S>'AS XML) AS Data
FROM #Sql)AS A
CROSS apply data.nodes('/S') AS Split(a))
SELECT Stuff((SELECT '; ' + data
FROM cte
WHERE rno%2 <> 0
AND data <> ''
FOR xml path ('')), 1, 2, '') AS ExpectedData
ExpectedData
-------------
100000161; 100000243; 100000161; 100000243
I believe this will get you what you are after as long as that pattern truly holds. If not it's fairly easy to ensure it does conform to that pattern and then apply this
Select Substring(TargetCol, 1, 10) + ';' From TargetTable
You can take advantage of SQL Server's XML support to convert the input string into an XML value and query it with XQuery and XPath expressions.
For example, the following query will replace each ; with </b><a> and each , to </a><b> to turn each string into <a>100000161</a><a>100000243</a><a />. After that, you can select individual <a> nodes with /a[1], /a[2] :
declare #table table (it nvarchar(200))
insert into #table values
('100000161, 100000031; 100000243, 100000021;'),
('100000161, 100000031; 100000243, 100000021;')
select
xCol.value('/a[1]','nvarchar(200)'),
xCol.value('/a[2]','nvarchar(200)')
from (
select convert(xml, '<a>'
+ replace(replace(replace(it,';','</b><a>'),',','</a><b>'),' ','')
+ '</a>')
.query('a') as xCol
from #table) as tmp
-------------------------
A1 A2
100000161 100000243
100000161 100000243
value extracts a single value from an XML field. nodes returns a table of nodes that match the XPath expression. The following query will return all "keys" :
select
a.value('.','nvarchar(200)')
from (
select convert(xml, '<a>'
+ replace(replace(replace(it,';','</b><a>'),',','</a><b>'),' ','')
+ '</a>')
.query('a') as xCol
from #table) as tmp
cross apply xCol.nodes('a') as y(a)
where a.value('.','nvarchar(200)')<>''
------------
100000161
100000243
100000161
100000243
With 200K rows of data though, I'd seriously consider transforming the data when loading it and storing it in indivisual, indexable columns, or add a separate, related table. Applying string manipulation functions on a column means that the server can't use any covering indexes to speed up queries.
If that's not possible (why?) I'd consider at least adding a separate XML-typed column that would contain the same data in XML form, to allow the creation of an XML index.
How can I return the values of MainEmail in the query below, delimited by commas and still count MDCselect?
declare #MainHospital varchar(50)='hospital 1'
select distinct mainhospital , f.Item, count(*) Count
from SurveyPicList s
cross apply splitstrings(s.MDCselect,':') as f
WHERE MainHospital = #MainHospital
GROUP BY MainHospital, f.Item
ORDER BY Count DESC
To be clear the above returns this: http://i.imgur.com/F1oPU6P.jpg
So there were 3 separate entries/people that selected "02-Eye". I want to list out their emails(MainEmail) comma delimited. Please let me know if I am unclear.
Assuming from your use of CROSS APPLY that you are using SQL Server, and that it is at least version 2005, you can use XML to do the concatenation as follows:
declare #MainHospital varchar(50)='hospital 1';
select mainhospital , f.Item, count(*) Count
,Stuff(
(select distinct ', ' + m.MainEmail
from SurveyPicList m
where m.MainHospital = #MainHospital
and ':' + m.MDCselect + ':' like '%:' + f.Item + ':%'
FOR XML PATH ('')),
1, 2, '') as Emails
from SurveyPicList s
cross apply splitstrings(s.MDCselect,':') as f
WHERE MainHospital = #MainHospital
GROUP BY MainHospital, f.Item
ORDER BY Count DESC
From the name I am assuming that splitstrings splits its first argument into items separated by its second argument. Hence I used like to check for f.Item in m.MDCselect in the WHERE condition of the subselect. Actually, what this WHERE condition is doing is collecting all the rows from another instance of the same table that match one record in the final grouped output.
I have table with data 1/1 to 1/20 in one column. I want the value 1 to 20 i.e value after '/'(front slash) is updated into other column in same table in SQL Server.
Example:
Column has value 1/1,1/2,1/3...1/20
new Column value 1,2,3,..20
That is, I want to update this new column.
Try this:
UPDATE YourTable
SET Col2 = RIGHT(Col1,LEN(Col1)-CHARINDEX('/',Col1))
Please find the below query also split the string with delimeter.
Select Substring(#String1,0,CharIndex(#delimeter,#String1))
From: http://www.sql-server-helper.com/error-messages/msg-536.aspx
To use function LEFT if not all data is in the form '1/12' you need this in the second line above:
Set Col2 = LEFT(Col1, ISNULL(NULLIF(CHARINDEX('/', Col1) - 1, -1), LEN(Col1)))
SELECT SUBSTRING(ParentBGBU,0,CHARINDEX('-',ParentBGBU,0)) FROM dbo.tblHCMMaster;
I know this question is specific to sql server, but I'm using postgresql and came across this question, so for anybody else in a similar situation, there is the split_part(string text, delimiter text, field int) function.
Maybe something like this:
First some test data:
DECLARE #tbl TABLE(Column1 VARCHAR(100))
INSERT INTO #tbl
SELECT '1/1' UNION ALL
SELECT '1/20' UNION ALL
SELECT '1/2'
Then like this:
SELECT
SUBSTRING(tbl.Column1,CHARINDEX('/',tbl.Column1)+1,LEN(tbl.Column1))
FROM
#tbl AS tbl
SELECT emp.LoginID, emp.JobTitle, emp.BirthDate, emp.ModifiedDate ,
CASE WHEN emp.JobTitle NOT LIKE '%Document Control%' THEN emp.JobTitle
ELSE SUBSTRING(emp.JobTitle,CHARINDEX('Document Control',emp.JobTitle),LEN('Document Control'))
END
,emp.gender,emp.MaritalStatus
FROM HumanResources.Employee [emp]
WHERE JobTitle LIKE '[C-F]%'
Use CHARINDEX. Perhaps make user function. If you use this split often.
I would create this function:
CREATE FUNCTION [dbo].[Split]
(
#String VARCHAR(max),
#Delimiter varCHAR(1)
)
RETURNS TABLE
AS
RETURN
(
WITH Split(stpos,endpos)
AS(
SELECT 0 AS stpos, CHARINDEX(#Delimiter,#String) AS endpos
UNION ALL
SELECT endpos+1, CHARINDEX(#Delimiter,#String,endpos+1)
FROM Split
WHERE endpos > 0
)
SELECT 'INT_COLUMN' = ROW_NUMBER() OVER (ORDER BY (SELECT 1)),
'STRING_COLUMN' = SUBSTRING(#String,stpos,COALESCE(NULLIF(endpos,0),LEN(#String)+1)-stpos)
FROM Split
)
GO
I am trying to achive this:
Initial table:
PARM1 |PARM2 |DATE
-------------------
VALUE1|VALUE2|DATE1
VALUE3|VALUE4|DATE2
Final result:
PARM |DATE1 |DATE2 |...
-----------------------
PARM1|VALUE1|VALUE3|...
PARM2|VALUE2|VALUE4|...
Briefly, I want to convert my parameter names into lines and to have a column for every date, where the cells contain the parameter values for the date and parameter.
So far, I managed to get this:
SELECT *
FROM
(
SELECT [Parameter], [DATE], VALUE
FROM
(
SELECT PARM1, PARM2 FROM PARAMETER_VALUES
) SOURCE_TABLE
UNPIVOT
(
VALOR FOR [Parameter] IN (PARM1, PARM2)
) UNPIVOTED_TABLE
) T
The problem is, I can't PIVOT the results now, because I don't know how many DATEs there are. I want it to be dynamic.
Is it possible?
In short, you can't use the PIVOT command with unknown columns.
Your only option is to retrieve the data and reformat, using dynamic SQL or some kind of front end.
You can pivot using dynamic columns, if you build the pivot before hand.
SELECT #listColYouwantInPivot= STUFF(( SELECT distinct '], [' + [columnName]
FROM tableName
FOR
XML PATH('')
), 1, 2, '') + ']'
Just plug #listColYouwantInPivot in the pivot statement with a concatenation afterward.
