SQL Server: any equivalent of strpos()?

Question

I\'m dealing with an annoying database where one field contains what really should be stored two separate fields. So the column is stored something like \"The first string~

Answer 1

If you need your data in columns here is what I use:

  create FUNCTION [dbo].[fncTableFromCommaString] (@strList varchar(8000))  
RETURNS @retTable Table (intValue int) AS  
BEGIN 

    DECLARE @intPos tinyint

    WHILE CHARINDEX(',',@strList) > 0
    BEGIN   
        SET @intPos=CHARINDEX(',',@strList) 
        INSERT INTO @retTable (intValue) values (CONVERT(int, LEFT(@strList,@intPos-1)))
        SET @strList = RIGHT(@strList, LEN(@strList)-@intPos)
    END
    IF LEN(@strList)>0 
        INSERT INTO @retTable (intValue) values (CONVERT(int, @strList))

    RETURN

END

Just replace ',' in the function with your delimiter (or maybe even parametrize it)

Answer 2

User charindex:

Select CHARINDEX ('S','MICROSOFT SQL SERVER 2000')
Result: 6

Answer 3

The PatIndex function should give you the location of the pattern as a part of a string.

PATINDEX ( '%pattern%' , expression )
