Answer 2

.....SET @COUNT=@COUNT+1
END

DEALLOCATE FP_cursor
RETURN @TMPSTR
END

Answer 3

再问一个
在函数里可不可以用
PRINT 'ok'
这样的语句

Answer 4

DECLARE FA_cursor CURSOR FOR
select FNumber,FParentID
from t_account
where FAccountID=@FAccountID
SET @FAccountID=1000
OPEN FA_cursor
...........
CLOSE FA_cursor
SET @FAccountID=1002
OPEN FA_cursor
...........
CLOSE FA_cursor
-----------------------------
这们的写法行不行?
