错误： ORA-06550：第1行，第15栏 PLS-00103：遇到符号＆＃34;;＆＃34;期待下列之一。

你能解决这个问题吗？

Answer 1

请使用ANONYMOUS BLOCK

的正确语法

DECLARE 
    en NUMBER;
    ei NUMBER;
    ec NUMBER;
BEGIN
    empl_info('balu',ei,ec,en);
    DBMS_OUTPUT.PUT_LINE('EN :'||en);
    DBMS_OUTPUT.PUT_LINE('EC :'||ec);
END;

Answer 2

SQL> CREATE or REPLACE PROCEDURE empl_info(ename VARCHAR2,empid OUT NUMBER,empcount OUT NUMBER,empname OUT VARCHAR2) IS
BEGIN
  SELECT COUNT(emp_name) INTO empcount FROM employees WHERE emp_name=ename;
  SELECT emp_name, emp_id INTO empname,empid FROM employees WHERE emp_name=ename;
  dbms_output.put_line(' employee name : '||empname||'  |  employee count : '||empcount);
END;

只调用没有OUT或OUTPUT的变量

SQL> set serveroutput on;
SQL> var ei number;
SQL> var ec number;
SQL> var en varchar2(100);
SQL> exec empl_info('balu',:ei,:ec,:en);
