是否可以在plsql中执行一个动态的sql,并将结果返回到sys_refcursor?我已经粘贴了我的尝试太远了,但dosnt接缝工作,这是错误我通过我的
java应用程序
ORA-01006: bind variable does not
exist ORA-06512: at
“LIVEFIS.ERC_REPORT_PK”,line 116
ORA-06512: at line 1
但是这可能是由java错误的一切,所有接缝编译好的soo我不知道.
procedure all_carers_param_dy (pPostcode in carer.postcode%type,pAge Number,pReport out SYS_REFCURSOR) is begin declare lsql varchar2(500) :='SELECT c.id FROM carer c,cared_for cf,carer_cared_for ccf ' ||' where c.id = ccf.carer_id (+)' ||' AND cf.id (+) = ccf.cared_for_id'; begin if pPostcode is not null and pAge <= 0 then lsql := lsql||' AND c.postcode like ''%''|| upper(pPostcode)||''%'''; elsif pPostcode is null and pAge > 0 then lsql := lsql||' AND ROUND((MONTHS_BETWEEN(sysdate,c.date_of_birth)/12)) = pAge'; elsif pPostcode is not null and pAge > 0 then lsql := lsql ||' AND ROUND((MONTHS_BETWEEN(sysdate,c.date_of_birth)/12)) = pAge' ||' AND c.postcode like ''%''|| upper(pPostcode)||''%'''; end if; execute immediate lsql into pReport; end; end;
Im新到plsql甚至更新的动态sql soo任何帮助/建议将被大大的apreciated.
再次感谢

解决方法
你必须绑定参数pAge和pPostcode.在动态sql中,您将以冒号(:)前缀.如果使用EXECUTE IMMEDIATE或OPEN … FOR,您将通过位置绑定参数,这就是为什么我重命名它们:示例中的P1和P2:
DECLARE lsql VARCHAR2(500) := 'SELECT c.id FROM carer c,carer_cared_for ccf WHERE c.id = ccf.carer_id (+) AND cf.id (+) = ccf.cared_for_id'; BEGIN IF pPostcode IS NULL THEN lsql := lsql || ' AND :P1 IS NULL'; ELSE lsql := lsql || ' AND c.postcode like ''%''|| upper(:P1)||''%'''; IF pPostcode pAge > 0 THEN lsql := lsql || ' AND :P2 = ROUND((MONTHS_BETWEEN(sysdate,c.date_of_birth)/12))'; ELSE lsql := lsql || ' AND nvl(:P2,-1) <= 0'; END IF; OPEN pReport FOR lsql USING pPostcode,pAge; END;
注意:编译时必须知道绑定变量的数量和位置,这就是为什么我经常使用上面的结构(即使不使用参数也添加到它的位置).将一个重言式(如AND:P1 IS NULL)添加到查询中不会影响其解释计划.
