About oracle PL / SQL stored procedures PLS-00905 object is to resolve invalid, statement ignored the problem

Yesterday in learning oracle stored procedure, write a demo of a stored procedure, the statement is this:

 

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;
/

The idea is to find the number varchar type field by the table (20) Type field, change the number and types of fields. Table structure is as follows:

create table TESTDELETE
(
    TESTID   NUMBER,
    TESTNAME VARCHAR2(20)
)

The stored procedure calls, results appear as follows:

Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

CREATE 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  /

BEGIN
    RAISESALARY('name2091');
    COMMIT;
END;

Error: the stored procedure is invalid.

what? Obviously just created stored procedures ah. Then I turn to a word after you've created above, Warning: Procedure the Created with Compilation errors.  Translation should be: with the process of creating a compilation error.

That created a stored procedure error, then OK, look for stored procedures and see what was wrong.

emmmm, I looked back a long time, so a few lines, life and death in the end did not see what the problem, no way, baidu, google.

Later in StackOverFlow saw this, the original link is as follows:

https://stackoverflow.com/questions/48497140/oracle-sql-stored-procedure-object-invalid

Landlord found inside such a sentence:

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;

In other words, you can not specify the size or the accuracy of the data parameters to functions and stored procedures. OK, I look back at this argument, understand, varchar2 (20) is a significant parameter specifies the type of precision to the. Varchar2 need to change this type.

Or write directly to   the table name.% TYPE field is also possible (pro-test) .

After you have finished changing run as follows:

 

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 raise3091

PL/SQL procedure successfully completed.

SQL> 

 

 

After we have seen no clear warning of the emergence of a   Procedure created.

Running success! problem solved.
