sql-server - 如何使用 SQL Server 中的存储过程在单个查询中插入多行

Question

CREATE PROCEDURE Usp_insertgender
    (@gendervalues VARCHAR(MAX))
AS
BEGIN
    INSERT INTO sparsha.dbo.Genders ([GenderName])
    VALUES @gendervalues;
END

我尝试了上述过程，但出现错误

Msg 102, Level 15, State 1, Procedure Usp_insertgender, Line 10
Incorrect syntax near '@gendervalues'.

我将 @gendervalues 值传递为 ('1'),('2')

Answer 1

可能最简单的方法是定义 TVP :

CREATE TYPE myTVPType AS TABLE( v VARCHAR(50));  
GO  

CREATE PROCEDURE Usp_insertgender (@gendervalues myTVPType READONLY) 
AS 
BEGIN
  INSERT INTO sparsha.dbo.Genders ([GenderName]) 
  SELECT v
  FROM @gendervalues; 
END;

如何调用:

DECLARE @tvp AS myTVPType;  

INSERT INTO @TVP (v)  
VALUES ('1'),('2');

EXEC Usp_insertgender @TVP;  
GO
