Question

im trying to realize something like this:

DECLARE @id int
declare @cont varchar(max)
declare @temp varchar(max)
DECLARE curs CURSOR FOR SELECT id, [content] FROM [dbo].[Contents]

OPEN curs

FETCH NEXT FROM curs into @id, @cont
WHILE @@FETCH_STATUS = 0
   BEGIN
      SET @temp = replace(@cont, @param_ReplaceThis, @param_WithReplacement)

      update [dbo].[Contents]
         set [Content] = @temp
        where id = @id;

      FETCH NEXT FROM curs into @id, @cont;
   END;
CLOSE curs;
DEALLOCATE curs;

but i always get the errormessage that it’s not allowed to use ‘UPDATE’ within a function… i only that this stuff is working fine on Oracle…

Answer 1

Why use cursor for something that basicaly is a simple set operation?

UPDATE [dbo].[Contents] 
SET [Content] = replace([Content], @param_ReplaceThis, @param_WithReplacement)

Answering your question further, you can add FOR UPDATE [ OF column_name, … ] to your DECLARE CURSOR statement. If you omit [ OF column name, … ] then all columns will be updateable.
