如何做一个firebird SP，SELECT * FROM“TABLE”？

发布于 2024-08-12 07:30:00 字数 348 浏览 4 评论 0原文

我正在从 SQL Server 迁移到 Firebird。

在 SQL Server 中，

CREATE PROCEDURE Departments_GetAll
AS
    SELECT * FROM Departments

我在 Firebird 中尝试，

CREATE PROCEDURE DEPARTMENTS_DELETEALL
AS 
BEGIN
  SELECT * FROM "Departments";
END^

SET TERM ; ^

但这不起作用。

它返回错误“SQL 代码 -104”

I'm migrating from SQL Server to Firebird.

In SQL Server

CREATE PROCEDURE Departments_GetAll
AS
    SELECT * FROM Departments

I try in Firebird

CREATE PROCEDURE DEPARTMENTS_DELETEALL
AS 
BEGIN
  SELECT * FROM "Departments";
END^

SET TERM ; ^

But that doesn't work.

It returns an error "SQL Code -104"

存储过程需要返回参数和挂起命令才能返回多行。

CREATE PROCEDURE DEPARTMENTS_GET_ALL
returns(id integer, name varchar(100))
AS 
BEGIN
  FOR SELECT id, name
  FROM "Departments"
  into :id, :name do
  BEGIN
    SUSPEND;
  END
END^

SET TERM ; ^

A stored procedure needs return parameters and the suspend command in order to return multiple rows.

CREATE PROCEDURE DEPARTMENTS_GET_ALL
returns(id integer, name varchar(100))
AS 
BEGIN
  FOR SELECT id, name
  FROM "Departments"
  into :id, :name do
  BEGIN
    SUSPEND;
  END
END^

SET TERM ; ^
