Hi we are migrating a procedure from mssql to mysql.
if i executed the following function on mysql iam getting "Not allowed to return a result set from a function" error.
CREATE FUNCTION TABLE_COL_LIST(xtable VARCHAR(100),includeclientid varchar(1)) RETURNS varchar(4000)
BEGIN
DECLARE colname VARCHAR(300);declare collist VARCHAR(4000);declare foundclientid VARCHAR(200);
declare cnt int default 0;
declare fetch_status int default 0;
  DECLARE table_cur CURSOR FOR
SELECT COLUMN_NAME FROM information_schema.COLUMNS C where TABLE_SCHEMA=(select database()) and table_name=xtable;
select fetch_status;
  SET @collist = '';
  IF (includeclientid IS NULL) then
  BEGIN
     SET includeclientid = 'F';
  END;
  end if;
  begin
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET fetch_status =-1;
   OPEN table_cur;
  FETCH FROM table_cur INTO colname;
     WHILE (fetch_status=0) do
  BEGIN
      IF NOT(colname = 'CLIENT_ID') then
begin
      IF (@collist = '') then
           SET @collist = colname;
      ELSE
        set  @collist=concat(@collist ,',',colname);
        END if;
end;
    ELSE IF (includeclientid = 'T') then
      SET foundclientid = colname;
      end if;
       END if;
     FETCH NEXT FROM table_cur INTO colname;
end;
  end while;
  CLOSE table_cur;
  end;
  IF NOT(foundclientid IS NULL) AND (includeclientid = 'T') then

Just underneath your cursor declaration, you have:

select fetch_status;

That would return a result set.
