Help modifying search and replace stored proc

Hi everyone.
I need to modify this search and replace stored proc currently If I perform

exec searchandreplace 'tom', 'tommy'   it will find things like 'tomorrow' and make it 'tommyorrow'. What I need it to do is only do replacements for Full String replacement ("tom" must match "tom" exactly)

A work around to having to find the Full String replacement ("tom" must match "tom" exactly) could be a way to specify a specific column names to replace in.

But for this to work It would have to work for a range of column names as its not exactly the same in all tables.

Thanks

      @SearchStr nvarchar(100),

If you want an exact match, take the '%' out of your string.

so make the line

SET @SearchStr2 = QUOTENAME('%' + @SearchStr + '%','''')

like this ?

SET @SearchStr2 = QUOTENAME(@SearchStr,'''')

Hi tconnelly, this one is easy enough. The other aspects will be more tricky, but you'll get much more traction with others taking a task at a time. Have fun.
