Question

我是一个完整的新手，我被要求为upsert编写存储过程

我想做以下事情：

exectute upsert(1,'locationA');

我谷歌并发现：

CREATE OR REPLACE PROCEDURE TABLE_UPSERT (v_id IN NUMBER,
                                          v_searches IN VARCHAR2(20),
                                          v_account IN VARCHAR2(20)) AS
BEGIN
  INSERT INTO table (id, searches, account) VALUES (v_id, v_searches, v_account) ;
EXCEPTION
  WHEN DUP_VAL_ON_INDEX THEN
    UPDATE TABLE
    SET searches = v_searches, account = v_account
    WHERE id = v_id;
END;
/

然后我尝试将其修改为：

    CREATE OR REPLACE PROCEDURE upsert (a IN NUMBER, b IN varchar(40) ) 
    AS
    BEGIN
      INSERT INTO zone_location VALUES (a, b) ;
    EXCEPTION
      WHEN DUP_VAL_ON_INDEX THEN
      UPDATE zone_location
      SET location = b
      WHERE zid = a;
    END;
    /

即使没有EXCEPTION部分，我也被告知： PLS-00103：在期待......时遇到符号"("。

感谢您的关注。任何帮助将不胜感激。

Answer 1

参数类型不需要大小。将VARCHAR2(20)更改为VARCHAR2。

SQL> create or replace procedure test_procedure(a varchar2)
  2  is
  3  begin
  4    null;
  5  end;
  6  /

Procedure created.

SQL * Plus错误消息包含有助于指出问题的行号和列号。请注意，列号为36个字符，但不包括create or replace。

SQL> create or replace procedure test_procedure(a varchar2(10))
  2  is
  3  begin
  4    null;
  5  end;
  6  /

Warning: Procedure created with compilation errors.

SQL> show errors
Errors for PROCEDURE TEST_PROCEDURE:

1/36     PLS-00103: Encountered the symbol "(" when expecting one of the
         following:

         The symbol ":=" was substituted for "(" to continue.

sql加上upsert的存储过程
