Question

我正在使用sqlplus代码和plsql，我在plsql中的程序工作正常，但是当我在sql中执行程序时，我遇到了一些错误报告。继承我的代码：

set serveroutput on;

DECLARE
ENDDATE DATE;
BEGIN

SELECT SOME_DATE INTO ENDDATE FROM HEADER WHERE ID=1182446;

IF ENDDATE >= TO_DATE('18-MAY-13') THEN
  EXECUTE SOMEPROCEDURE(1182446);
END IF;

END;

Error report -
ORA-06550: line 8, column 8:
PLS-00103: Encountered the symbol "SOMEPROCEDURE" when expecting one of the following:

   := . ( @ % ;
The symbol ":=" was substituted for "SOMEPROCEDURE" to continue.
06550. 00000 -  "line %s, column %s:\n%s"
*Cause:    Usually a PL/SQL compilation error.
*Action:

Answer 1

IF ENDDATE >= TO_DATE('18-MAY-13') THEN
  EXECUTE SOMEPROCEDURE(1182446);
END IF;

由于您在匿名PL / SQL块中调用该过程，因此不需要 EXECUTE 命令，因为它是 SQL *加命令而不是PL / SQL。

您只需将程序调用为：

IF ENDDATE >= TO_DATE('18-MAY-13') THEN
  SOMEPROCEDURE(1182446);
END IF;

如果您想在 SQL * Plus 中单独执行该程序，则可以使用 EXECUTE 或 EXEC 命令。

例如，

在SQL * Plus中：

SQL> CREATE OR REPLACE
  2  PROCEDURE get_emp(
  3      emp_no IN emp.empno%type,
  4      dept_no OUT emp.deptno%type )
  5  AS
  6  BEGIN
  7    SELECT deptno INTO dept_no FROM emp WHERE empno = emp_no;
  8  END;
  9  /

Procedure created.

SQL> var dno number
SQL>  var eno number
SQL> exec :eno := 7369

PL/SQL procedure successfully completed.

SQL> EXEC get_emp(:eno, :dno);

PL/SQL procedure successfully completed.

SQL> print dno

       DNO
----------
        20

SQL>

如果你想在另一个PL / SQL块中调用该过程，那么你可以这样做：

匿名PL / SQL块：

SQL> set serveroutput on
SQL> DECLARE
  2    dt      DATE;
  3    dept_no NUMBER;
  4  BEGIN
  5    SELECT hiredate INTO dt FROM emp WHERE empno = 7369;
  6    IF dt < SYSDATE THEN
  7      get_emp(7369, dept_no);
  8      DBMS_OUTPUT.PUT_LINE('Department number is '||dept_no);
  9    END IF;
 10  END;
 11  /
Department number is 20

PL/SQL procedure successfully completed.

在sqlplus里面调用程序
