I want to check if a ID is present or not in a set of multiple ID.
Example
if id 5 is present in multiple id list like '1,2,3,4,5'
use CHARINDEX to return the index of the searched value.
Declare #MyString varchar(50)
Set #MyString = '1,2,3,4,5'
IF CHARINDEX('5',ContactName) > 0
Begin
Print '5 Exists'
End
Else
Begin
Print '5 Does not exists'
End
select count(*) FROM table where id = '5';
If it returns more than 0 means it's present.
If you are talking about sql this query will work for you, if you get nothing it means searching id is not there in the list else there.
SELECT * FROM journal_pulses WHERE mood_credentials in (2,27)
SELECT column FROM table WHERE CHARINDEX(',5,',(',' + column + ',')) > 0
Fiddle
One good solution in this context could be to store the values with leading and trailing comma, as:
',1,2,3,4,5,'
So, even if you store one value, store it as:
',5,'
This will help you look for required value as:
SELECT column FROM table WHERE column like '%,5,%';
Or
SELECT column FROM table WHERE CHARINDEX(',5,',(',' + column + ',')) > 0
Also, using this solution you can uniquely identify different values, given that the string does not contain duplicate values.
So, it is easy to identify 5, 50 and 350 from:
',5,50,150,250,350,450,500,'
I am not sure if you can change how the values can be stored. Please read this answer in light of the context of the question - as a starting point and not as a copy-paste solution.
I have tried something like this
DECLARE #item VARCHAR(50)
SET #ExpressionToSearch = '23,12'
SET #item = '23'
SELECT COUNT(*) from dbo.Split(#ExpressionToSearch,',')
WHERE ',' + (#ExpressionToSearch) + ','
LIKE '%'+#item +'%'
This scenario will return output greater than 0

I have data in a #temp_table like this:
SCORM_VARNAME
1) cmi.interactions.0.id
2) cmi.interactions.1.id
3) cmi.interactions.10.id
4) cmi.interactions.5.id
5) cmi.interactions.8.id
etc etc...
In the above example, the number I am ULTIMATELY wanting to save in a variable is 10.
I want to return the highest number that appears in these tables, it can be 0-100000 (I doubt it) but it can't be hardcoded for example. It could only go up to 3!
I have the following code that basically takes whatever string you give it, and CORRECTLY extracts the number, which is great!
DECLARE #string varchar(100)
SET #string = 'cmi.interactions.10.id'
WHILE PATINDEX('%[^0-9]%',#string) <> 0
SET #string = STUFF(#string,PATINDEX('%[^0-9]%',#string),1,'')
SELECT #string
Except I am not sure how to run this function across all the rows in the temp_table and to either replace each row with the highest number, or to return the highest number.
So either I need to figure out a way to return the highest number found in the table, or if you guys could help me by figuring out some way to UPDATE the temp_table, and replacing each string with the number found in it... I would be able to do the rest.
set #v = (
select max(cast(replace(replace(s, 'cmi.interactions.', ''), '.id', '') as int))
from T
);
Late answer ... Just another option is parsename()
Example
Declare #YourTable Table ([SCORM_VARNAME] varchar(50))
Insert Into #YourTable Values
('cmi.interactions.0.id')
,('cmi.interactions.1.id')
,('cmi.interactions.10.id')
,('cmi.interactions.5.id')
,('cmi.interactions.8.id')
Select *
,Value = try_convert(int,parsename(Scorm_Varname,2))
From #YourTable
Returns
SCORM_VARNAME Value
cmi.interactions.0.id 0
cmi.interactions.1.id 1
cmi.interactions.10.id 10
cmi.interactions.5.id 5
cmi.interactions.8.id 8
For the MAX
Select Value = max(try_convert(int,parsename(Scorm_Varname,2)))
From #YourTable
I start to work on old project and there is sql server database column which stores articles numbers for example as follows:
11.1006.45
11.1006.46
11.1006.47
01.10012.11
01.10012.12
2.234.1
2.234.2
2.234.3
657.104324.32
Every number contains 3 parts. First part describe what producent it is and that's something i have to change when user choose diffrent number for specific producent. For example producent number 2 will be now 13 so according to our examples:
2.234.1
2.234.2
2.234.3
has to be done this way right now:
13.234.1
13.234.2
13.234.3
I am looking for sql query which would find all records where producent number is e.g 2.xxxxx and then replace to 13.xxxxx. I would like this query to be secure to avoid any issues with numbers replacments.Hope you understand what i ment.
You could use this for update. '2. and 13.' could be any other string
DECLARE #SampleTable AS TABLE
(
Version varchar(100)
)
INSERT INTO #SampleTable
VALUES
('11.1006.45'),
('11.1006.46'),
('11.1006.47'),
('01.10012.11'),
('01.10012.12'),
('2.234.1'),
('2.234.2'),
('2.234.3'),
('657.104324.32')
UPDATE #SampleTable
SET
Version = '13.' + substring(Version, charindex('.', Version) + 1, len(Version) - charindex('.', Version))
WHERE Version LIKE '2.%'
SELECT * FROM #SampleTable st
Demo link: Rextester
update t
set t.col= replace(yourcol,substring(yourcol,1,charindex('.',yourcol,1),2)
from table t
this finds first character before first dot
substring(yourcol,1,charindex('.',yourcol,1)
then you use replace ,to replace it with whatever you need
You can use this query for multiple updation,
DECLARE #Temp AS TABLE
(
ArtNo VARCHAR(100)
)
INSERT INTO #Temp
VALUES
('11.1006.45'),
('11.1006.46'),
('11.1006.47'),
('01.10012.11'),
('01.10012.12'),
('2.234.1'),
('2.234.2'),
('2.234.3'),
('657.104324.32')
UPDATE #Temp
SET ArtNo = CASE WHEN SUBSTRING(ArtNo,1,CHARINDEX('.',ArtNo)-1) = '2' THEN STUFF(ArtNo,1,CHARINDEX('.',ArtNo)-1,'13')
WHEN SUBSTRING(ArtNo,1,CHARINDEX('.',ArtNo)-1) = '11' THEN STUFF(ArtNo,1,CHARINDEX('.',ArtNo)-1,'15')
ELSE ArtNo
END
SELECT * FROM #Temp
I have a comma-separated list column available which has values like
Product1, Product2, Product3
I need to search whether the given product name exists in this column.
I used this SQL and it is working fine.
Select *
from ProductsList
where productname like '%Product1%'
This query is working very slowly. Is there a more efficient way I can search for a product name in the comma-separated list to improve the performance of the query?
Please note I have to search comma separated list before performing any other select statements.
user defined functions for comma separation of the string

Felix is right and the 'right answer' is to normalize your table. Although, maybe you have 500k lines of code that expect this column to exist as it is. So your next best (non-destructive) answer is:
Create a table to hold normalize data:
CREATE TABLE ProductsList2 (ProductId INT, ProductName VARCHAR)
Create a TRIGGER that on UPDATE/INSERT/DELETE maintains ProductList2 by splitting the string 'Product1,Product2,Product3' into three records.
Index your new table.
Query against your new table:
SELECT *
FROM ProductsList
WHERE ProductId IN (SELECT x.ProductId
FROM ProductsList2 x
WHERE x.ProductName = 'Product1')
I've got a column of type Text. In the column are numeric values such as4, 8, 3.2, etc... and also values such as 'Negative', 'Positive', '27A', '2pos 1neg'.
The user needs to be able to say: "Give me all the values between 10 and 30, and also the values that are 'Negative'. The WHERE clause would need to do something along the lines of:
WHERE Tbl.Col > 10
AND Tbl.Col < 30
AND Tbl.Col = 'Negative'
This is problematic for obvious reasons. I've tried using the ISNUMERIC function to alleviate the issue but can't seem to get exactly what i need. I can either get all the alpha values in the column, or all the numeric values in the column as floats but cant seem to filter on both at the same time. To grab all the Numeric values I've been using this:
SELECT Num.Val FROM
(SELECT Val = CASE ISNUMERIC(CAST(TBL.COL AS VARCHAR)) WHEN 1
THEN CAST(CAST(TBL.COL AS VARCHAR) AS FLOAT) ELSE NULL END
FROM Table TBL
WHERE TBL.COL IS NOT NULL ) as Num
WHERE Num.val IS NOT NULL
AND Num.val > 10
If I understand the issue correctly something like this should get you close.
with MyNumbers as
(
select t.Col
from Tbl t
--where ISNUMERIC(t.Col) = 1
where t.Col NOT LIKE '%[^0-9.]%'
)
, MyAlpha as
(
select t.Col
from Tbl t
where ISNUMERIC(t.Col) = 0
)
select Col
from MyNumbers
where Col > 10
and Col < 30
union all
select Col
from MyAlpha
where ColorMatch = ' Negative'
First I would go slap the person who designed the table (hopefully it isn't you) :>
Go to here and get the split table function. I would then convert the text column (like you have in example above) into varchar(max) and supply it as the parameter to the split function. Then you could select from the table results of the split function using the user supplied parameters.
I have found the answer to my problem:
SELECT
al_Value = Table.Column
FROM Table
WHERE (
ISNUMERIC(CAST(Table.Column AS VARCHAR)) = 1 AND
CONVERT(FLOAT, CAST(Table.Column AS VARCHAR)) > 1.0 AND
CONVERT(FLOAT, CAST(Table.Column AS VARCHAR)) < 10.0
)
OR (
CAST(Table.Column AS VARCHAR) IN ('negative', 'no bueno')
)
This will return one column named 'al_Value' that filters on Table.Column (which is of Datatype TEXT) and apply the filters in the WHERE clause above.
Thanks everyone for trying to help me with this issue.
I am stuck on converting a varchar column UserID to INT. I know, please don't ask why this UserID column was not created as INT initially, long story.
So I tried this, but it doesn't work. and give me an error:
select CAST(userID AS int) from audit
Error:
Conversion failed when converting the varchar value
'1581............................................................................................................................' to data type int.
I did select len(userID) from audit and it returns 128 characters, which are not spaces.
I tried to detect ASCII characters for those trailing after the ID number and ASCII value = 0.
I have also tried LTRIM, RTRIM, and replace char(0) with '', but does not work.
The only way it works when I tell the fixed number of character like this below, but UserID is not always 4 characters.
select CAST(LEFT(userID, 4) AS int) from audit
You could try updating the table to get rid of these characters:
UPDATE dbo.[audit]
SET UserID = REPLACE(UserID, CHAR(0), '')
WHERE CHARINDEX(CHAR(0), UserID) > 0;
But then you'll also need to fix whatever is putting this bad data into the table in the first place. In the meantime perhaps try:
SELECT CONVERT(INT, REPLACE(UserID, CHAR(0), ''))
FROM dbo.[audit];
But that is not a long term solution. Fix the data (and the data type while you're at it). If you can't fix the data type immediately, then you can quickly find the culprit by adding a check constraint:
ALTER TABLE dbo.[audit]
ADD CONSTRAINT do_not_allow_stupid_data
CHECK (CHARINDEX(CHAR(0), UserID) = 0);
EDIT
Ok, so that is definitely a 4-digit integer followed by six instances of CHAR(0). And the workaround I posted definitely works for me:
DECLARE #foo TABLE(UserID VARCHAR(32));
INSERT #foo SELECT 0x31353831000000000000;
-- this succeeds:
SELECT CONVERT(INT, REPLACE(UserID, CHAR(0), '')) FROM #foo;
-- this fails:
SELECT CONVERT(INT, UserID) FROM #foo;
Please confirm that this code on its own (well, the first SELECT, anyway) works for you. If it does then the error you are getting is from a different non-numeric character in a different row (and if it doesn't then perhaps you have a build where a particular bug hasn't been fixed). To try and narrow it down you can take random values from the following query and then loop through the characters:
SELECT UserID, CONVERT(VARBINARY(32), UserID)
FROM dbo.[audit]
WHERE UserID LIKE '%[^0-9]%';
So take a random row, and then paste the output into a query like this:
DECLARE #x VARCHAR(32), #i INT;
SET #x = CONVERT(VARCHAR(32), 0x...); -- paste the value here
SET #i = 1;
WHILE #i <= LEN(#x)
BEGIN
PRINT RTRIM(#i) + ' = ' + RTRIM(ASCII(SUBSTRING(#x, #i, 1)))
SET #i = #i + 1;
END
This may take some trial and error before you encounter a row that fails for some other reason than CHAR(0) - since you can't really filter out the rows that contain CHAR(0) because they could contain CHAR(0) and CHAR(something else). For all we know you have values in the table like:
SELECT '15' + CHAR(9) + '23' + CHAR(0);
...which also can't be converted to an integer, whether you've replaced CHAR(0) or not.
I know you don't want to hear it, but I am really glad this is painful for people, because now they have more war stories to push back when people make very poor decisions about data types.
This question has got 91,000 views so perhaps many people are looking for a more generic solution to the issue in the title "error converting varchar to INT"
If you are on SQL Server 2012+ one way of handling this invalid data is to use TRY_CAST
SELECT TRY_CAST (userID AS INT)
FROM audit
On previous versions you could use
SELECT CASE
WHEN ISNUMERIC(RTRIM(userID) + '.0e0') = 1
AND LEN(userID) <= 11
THEN CAST(userID AS INT)
END
FROM audit
Both return NULL if the value cannot be cast.
In the specific case that you have in your question with known bad values I would use the following however.
CAST(REPLACE(userID COLLATE Latin1_General_Bin, CHAR(0),'') AS INT)
Trying to replace the null character is often problematic except if using a binary collation.
This is more for someone Searching for a result, than the original post-er. This worked for me...
declare #value varchar(max) = 'sad';
select sum(cast(iif(isnumeric(#value) = 1, #value, 0) as bigint));
returns 0
declare #value varchar(max) = '3';
select sum(cast(iif(isnumeric(#value) = 1, #value, 0) as bigint));
returns 3
I would try triming the number to see what you get:
select len(rtrim(ltrim(userid))) from audit
if that return the correct value then just do:
select convert(int, rtrim(ltrim(userid))) from audit
if that doesn't return the correct value then I would do a replace to remove the empty space:
select convert(int, replace(userid, char(0), '')) from audit
This is how I solved the problem in my case:
First of all I made sure the column I need to convert to integer doesn't contain any spaces:
update data set col1 = TRIM(col1)
I also checked whether the column only contains numeric digits.
You can check it by:
select * from data where col1 like '%[^0-9]%' order by col1
If any nonnumeric values are present, you can save them to another table and remove them from the table you are working on.
select * into nonnumeric_data from data where col1 like '%[^0-9]%'
delete from data where col1 like '%[^0-9]%'
Problems with my data were the cases above. So after fixing them, I created a bigint variable and set the values of the varchar column to the integer column I created.
alter table data add int_col1 bigint
update data set int_col1 = CAST(col1 AS VARCHAR)
This worked for me, hope you find it useful as well.
