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。
