就是一个普通的定义游标的存储过程，只是游标的select 语句中的where 后的字段名字和条件及取值都用参数传入，最麻烦的问题都解决了，可调用时就是报错
定义的包为：
CREATE OR REPLACE PACKAGE GET_EMP_NAME
AS
TYPE T_REF IS REF CURSOR;
PROCEDURE GET_ALL_EMPNAME(OPT VARCHAR2,TJ VARCHAR2,T_ID VARCHAR2,L_ID OUT T_REF);
END GET_EMP_NAME;
/
CREATE OR REPLACE PACKAGE BODY GET_EMP_NAME
AS
PROCEDURE GET_ALL_EMPNAME(OPT VARCHAR2,TJ VARCHAR2,T_ID VARCHAR2,L_ID OUT T_REF) AS
STR_SQL VARCHAR2(500);
BEGIN
STR_SQL:= 'OPEN L_ID FOR SELECT TASK_ID FROM EMPLOYEE ';
STR_SQL:= STR_SQL|| 'WHERE '||OPT||TJ|| 'T_ID ';
EXECUTE IMMEDIATE STR_SQL;
END GET_ALL_EMPNAME;
END GET_EMP_NAME;
/
这样调用的：
declare
e_name varchar2(4);
cursor_name get_emp_name.t_ref;
begin
get_emp_name.get_all_empname( 'TASK_ID ', '= ', '1 ',cursor_name);
loop
fetch cursor_name into e_name;
exit when cursor_name%notfound;
dbms_output.put_line(e_name);
end loop;
end;
/
报错：
declare
*
第一行出现错误：
ORA-00900:无效SQL语句
ORA-06512:在”SYSTEM.GET_EMP_NAME”, line 8
ORA-06512:在line 5
请各位看看。
------解决方案--------------------
用TOAD跟踪一下 看看你动态构件的SQL语句是否正确 然后再说
