在 Oracle 中调用另一个存储过程
有谁知道从另一个内部调用存储过程的方法，或者即使可能的话?如果是这样，你会怎么做?
Does anyone know of a way, or even if its possible, to call a stored procedure from within another? If so, how would you do it?
这是我的测试代码:
SET SERVEROUTPUT ON;
DROP PROCEDURE test_sp_1;
DROP PROCEDURE test_sp;
CREATE PROCEDURE test_sp
AS
BEGIN
DBMS_OUTPUT.PUT_LINE('Test works');
END;
/
CREATE PROCEDURE test_sp_1
AS
BEGIN
DBMS_OUTPUT.PUT_LINE('Testing');
test_sp;
END;
/
CALL test_sp_1;
推荐答案
您的存储过程按编码工作.问题出在最后一行，它无法调用您的任何一个存储过程.
Your stored procedures work as coded. The problem is with the last line, it is unable to invoke either of your stored procedures.
SQL*Plus 中的三个选项是:call、exec 和一个匿名的 PL/SQL 块.
Three choices in SQL*Plus are: call, exec, and an anoymous PL/SQL block.
call 似乎是一个 SQL 关键字，并记录在 SQL 参考中.http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_4008.htm#BABDEHHG 语法图表明需要括号，即使没有参数传递给调用例程.
call appears to be a SQL keyword, and is documented in the SQL Reference. http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_4008.htm#BABDEHHG The syntax diagram indicates that parentesis are required, even when no arguments are passed to the call routine.
CALL test_sp_1();
匿名 PL/SQL 块是不在命名过程、函数、触发器等内部的 PL/SQL.它可用于调用您的过程.
An anonymous PL/SQL block is PL/SQL that is not inside a named procedure, function, trigger, etc. It can be used to call your procedure.
BEGIN
test_sp_1;
END;
/
Exec 是一个 SQL*Plus 命令，它是上述匿名块的快捷方式.EXEC 将作为 BEGIN
Exec is a SQL*Plus command that is a shortcut for the above anonymous block. EXEC <procedure_name> will be passed to the DB server as BEGIN <procedure_name>; END;
完整示例:
SQL> SET SERVEROUTPUT ON
SQL> CREATE OR REPLACE PROCEDURE test_sp
2 AS
3 BEGIN
4 DBMS_OUTPUT.PUT_LINE('Test works');
5 END;
6 /
Procedure created.
SQL> CREATE OR REPLACE PROCEDURE test_sp_1
2 AS
3 BEGIN
4 DBMS_OUTPUT.PUT_LINE('Testing');
5 test_sp;
6 END;
7 /
Procedure created.
SQL> CALL test_sp_1();
Testing
Test works
Call completed.
SQL> exec test_sp_1
Testing
Test works
PL/SQL procedure successfully completed.
SQL> begin
2 test_sp_1;
3 end;
4 /
Testing
Test works
PL/SQL procedure successfully completed.
