– 1 Reverse the alpha in order to get the last position of a numeric value
SET @alphaReverse = REVERSE(@alpha)
– 2 Get the last position of a numeric figure
SET @NumPos = PATINDEX(‘%[0-9]%’, @alphaReverse)
– 3 Get the lenght of the string
SET @Len = LEN(@alpha)
– 4 Add a comma after the numeric data in case it’s no decimal number
SET @alpha = SUBSTRING(@alpha, 1, (@Len – @NumPos + 1))
+ ‘,’
+ SUBSTRING(@alpha, (@Len – @NumPos + 2), 50)

– Check if there is a zero (0) in the @alpha, then we later set the @decimal to 0
– if it’s 0 after the handling, else we set @decimal to NULL
– If 0 no match, else there is a match
SET @ZeroExists = CHARINDEX ( ’0′ , @alpha ,1 )

– Find position of , (comma)
SET @CommaPos = 1
SET @CommaPos = PATINDEX(‘%,%’, @alpha)
IF (@CommaPos = ”) BEGIN
SET @CommaPos = 20
END

SET @Pos = PATINDEX(‘%[^0-9]%’,@alpha)
– Replaces any aplha with ’0′ since we otherwice can’t keep track of where the decimal
– should be put in. We assume the numeric number has no aplhe inside. The regular way
– to solve this is to replace with ”, but then we miss the way to find the place to
– put in the decimal.
WHILE (@Pos > 0) BEGIN
SET @alpha = STUFF(@alpha, @pos, 1, ’0′)

– Since we in this case don’t want to set 0 if where is no numeric value, we set NULL to be safe
IF (@decimal = 0 AND @ZeroExists = 0) BEGIN
SET @decimal = NULL

dim sp
sp=split(string,”-”)

Now you can access first and second values by

sp(0) and sp(1)

My senario like this , I have one text box and one table called student(Name,Roll_No) and one Insert button to insert data in DB. If i type “amit-28″ in textbox then by clicking on Insert button “amit” should inserted into Name field and “28″ should inserted into RollNo field. So what code to write??or query ??

Thanking You

In the function dbo.udf_GetNumeric replace the line:

SET @intAlpha = PATINDEX(‘%[^0-9]%’, @strAlphaNumeric)

with following line at two places:

SET @intAlpha = PATINDEX(‘%[^0-9.]%’, @strAlphaNumeric)

‘Price: 3.56783′

I would just want to return 3.56783

I think you might have missed somewhere. Please recheck it at your end.

Thanks,
Nizam
