关于oracle PL/SQL存储过程 PLS-00905 object is invalid,statement ignored问题的解决
昨天在学习oracle存储过程的时候,写了一个存储过程的demo,语句是这样的:
CREATE OR REPLACE PROCEDURE RAISESALARY(PNAME IN VARCHAR2(20))AS psssal TESTDELETE.TESTID%TYPE;BEGIN SELECT TESTID INTO psssal FROM TESTDELETE WHERE TESTNAME=PNAME; UPDATE TESTDELETE SET TESTID=(TESTID+10000) WHERE TESTNAME=PNAME; DBMS_OUTPUT.PUT_LINE('The original salary'||psssal||' After the raise'||(psssal+1000));end;/
想法是通过表的varchar(20)类型字段找到number类型字段,然后更改number类型的字段。表结构如下:
create table TESTDELETE( TESTID NUMBER, TESTNAME VARCHAR2(20))
将存储过程调用,出现结果如下:
Connected to:Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit ProductionWith the Partitioning, OLAP, Data Mining and Real Application Testing optionsCREATE OR REPLACE PROCEDURE RAISESALARY(PNAME IN VARCHAR2(20)) 2 AS 3 psssal TESTDELETE.TESTID%TYPE; 4 BEGIN 5 SELECT TESTID INTO psssal FROM TESTDELETE WHERE TESTNAME=PNAME; UPDATE TESTDELETE SET TESTID=(TESTID+10000) WHERE TESTNAME=PNAME; DBMS_OUTPUT.PUT_LINE('The original salary'||psssal||' After the raise'||(psssal+1000)); 8 end; 9 /Warning: Procedure created with compilation errors.SET SERVEROUTPUT ON;BEGIN RAISESALARY('name2091'); COMMIT;END;SQL> 2 3 4 5 / RAISESALARY('name2091'); *ERROR at line 2:ORA-06550: line 2, column 5:PLS-00905: object TEST.RAISESALARY is invalidORA-06550: line 2, column 5:PL/SQL: Statement ignoredSQL>
出现错误 :该存储过程无效。
what?明明刚刚建立的存储过程啊。然后我就翻到上面创建完之后的一句话,Warning: Procedure created with compilation errors. 翻译过来应该是:创建的过程带有编译的错误。
也就是说创建存储过程有错误,那么OK,找找存储过程看看哪错了。
emmmm,回头看了半天,就这么几行,死活没看出到底哪出问题了,没办法,baidu,google。
后来在StackOverFlow看到了这个,原文链接如下:

楼主在里面发现了这么一句话:
You can’t give a size or precision restriction for the data type of a formal parameter to a function or procedure, so NUMBER(10,0)
should just be NUMBER
;
也就是说,你不能给函数和存储过程的参数指定数据的大小或者精度。OK,回头看看我这个参数,懂了,varchar2(20)是明显的给参数的类型指定精度了。需要改成varchar2这种类型。
或者直接写 表名.字段%TYPE 也是可以的(亲测) 。
更改完之后运行如下:
CREATE OR REPLACE PROCEDURE RAISESALARY(PNAME IN VARCHAR) 2 AS 3 psssal TESTDELETE.TESTID%TYPE; 4 BEGIN 5 SELECT TESTID INTO psssal FROM TESTDELETE WHERE TESTNAME=PNAME; UPDATE TESTDELETE SET TESTID=(TESTID+10000) WHERE TESTNAME=PNAME; DBMS_OUTPUT.PUT_LINE('The original salary'||psssal||' After the raise'||(psssal+1000)); 8 end; 9 /Procedure created.BEGIN RAISESALARY('name2091'); 3 COMMIT; 4 END; 5 /The original salary2091 After the raise3091PL/SQL procedure successfully completed.SQL>
改完之后明确看到已经没有warning了,出现的是 Procedure created.
运行成功!问题解决。
