Question

这是我添加多个播放器的存储过程：

CREATE PROCEDURE [dbo].[AddMultipleUserofSameCountry]    
    @UserIds NVARCHAR(MAX),       
    @CountryCode INT,    
    @OwnsHasAccess INT,   
    @QryResult INT OUTPUT    
AS    
BEGIN TRY    
    SET @QryResult  = 0;    

    BEGIN TRANSACTION    
    BEGIN  
        INSERT INTO Players (CountryCode, UserId, OwnsHasAccess, InsertedWhen) 
        VALUES (@CountryCode,
                (SELECT Value FROM dbo.SplitString(@UserIds, ',')),
                @OwnsHasAccess, GETDATE());  
    END    

    COMMIT TRANSACTION    

    SET @QryResult  = 1;    
END TRY    
BEGIN CATCH    
    ROLLBACK TRANSACTION    
    SET @QryResult  = 0;    
END CATCH

UserIds是逗号分隔的字符串值

DAL代码

array = string.Join(",", UserIds.Select(n => n.ToString()).ToArray());

SqlParameter sqlParam = cmdProc.Parameters.AddWithValue("@UserIds", array);
sqlParam.SqlDbType = SqlDbType.VarChar;

请建议有什么方法可以传递多个UserId插入多个玩家

您应该构建完整的行以在INSERT语句中使用：

CREATE PROCEDURE [dbo].[AddMultipleUserofSameCountry]    
 @UserIds nvarchar(MAX),       
 @CountryCode int,    
 @OwnsHasAccess int,   
 @QryResult int output    
AS    
 Begin Try    
  Set @QryResult  = 0;    
  Begin Transaction    
   Begin  
       INSERT INTO Players(CountryCode,UserId,OwnsHasAccess,InsertedWhen)
       SELECT @CountryCode, Value, @OwnsHasAccess, GETDATE()
          FROM dbo.SplitString(@UserIds,',');  
   END    

   Commit Transaction    
   Set @QryResult  = 1;    

 End Try    
 Begin Catch    
  Rollback Transaction    
  Set @QryResult  = 0;    
 End Catch

注意：我假设dbo.SplitString与SQL Server 2016中的STRING_SPLIT相同
