DB2存储过程实现查询表数据，生成动态SQL，并执行

PREPARE S1 FROM 'delete from test';
EXECUTE S1;

DECLARE V_CURSOR CURSOR FOR
SELECT DELETESQL,INSERTSQL FROM FJDC.V_I_DG_DM_ZY_WL_ZBHZ_ATTR T;

OPEN V_CURSOR;

FETCH V_CURSOR INTO V_DELETESQL,V_INSERTSQL;

CLOSE V_CURSOR;

WHILE true DO
表达式
END WHILE;

CREATE PROCEDURE "TEST"."TEST" ()
BEGIN
DECLARE V_DELETESQL VARCHAR(2000);
DECLARE V_INSERTSQL VARCHAR(2000);
DECLARE I_COUNT INT;

--确定循环次数
SELECT COUNT(INSERTSQL) INTO I_COUNT FROM FJDC.V_I_DG_DM_ZY_WL_ZBHZ_ATTR T;
IF I_COUNT > 0 THEN
--游标
DECLARE V_CURSOR CURSOR FOR
SELECT DELETESQL,INSERTSQL FROM FJDC.V_I_DG_DM_ZY_WL_ZBHZ_ATTR T;

OPEN V_CURSOR;
WHILE I_COUNT > 0 DO
SET I_COUNT = I_COUNT-1;
FETCH V_CURSOR INTO V_DELETESQL,V_INSERTSQL;

--执行动态SQL
PREPARE S1 FROM V_DELETESQL;
EXECUTE S1;

PREPARE S1 FROM V_INSERTSQL;
EXECUTE S1;

END WHILE;
CLOSE V_CURSOR;

END IF;
END
