TSQL Remove Special Characters

Usage: Select dbo.StripSpecialChars(‘abc12+=\34def’); returns abc1234def

Create Function [dbo].[StripSpecialChars](@Temp VarChar(1000))
Returns VarChar(1000)
AS
Begin

    Declare @KeepValues as varchar(50)
    Set @KeepValues = '%[^a-zA-Z0-9 ]%'
    While PatIndex(@KeepValues, @Temp) > 0
        Set @Temp = Stuff(@Temp, PatIndex(@KeepValues, @Temp), 1, '')

    Return @Temp
End

Adjust the @KeepValues as needed. Or if you want to get fancy, add it as a second input variable.
