如何用两个主键将行插入表中？

Question

我创建了下表：

CREATE TABLE [dbo].[tblArchLogDetail](
    [RecordID] [numeric](18, 0) NOT NULL,
    [TableName] [varchar](30) NOT NULL,
    [TotalRecords] [int] NULL,
    [ArchivedRecords] [int] NULL,
 CONSTRAINT [PK_tblArchLogDetail] PRIMARY KEY CLUSTERED 
(
    [RecordID] ASC,
    [TableName] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

那么，如何将行插入此表中？ 我不断收到错误“违反主键约束”。 这是我的示例代码：

Insert into tblArchLogDetail values(54,'tblAuditLogin',13128,0)

Answer 1

您在这里拥有的是所谓的“复合”主键。

这意味着您选择组成复合主键的值的任何组合都必须是唯一的。

您得到的错误仅表示该表中已经有一个记录，其RecordId为54，TableName为'tblAuditLogin'。

Answer 2

我认为您要尝试在RecordID字段中添加一个自动递增的整数。 如果是这样，请使其成为身份字段：

CREATE TABLE [dbo].[tblArchLogDetail](
    [RecordID] [numeric](18, 0) IDENTITY NOT NULL,
    [TableName] [varchar](30) NOT NULL,
    [TotalRecords] [int] NULL,
    [ArchivedRecords] [int] NULL,
 CONSTRAINT [PK_tblArchLogDetail] PRIMARY KEY CLUSTERED 
(
    [RecordID] ASC,
    [TableName] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

如果这不是您的意图，并且您确实想要在RecordID和TableName重复记录，请在RecordID之前放置一个标识字段，并将其添加到PRIMARY KEY约束中：

CREATE TABLE [dbo].[tblArchLogDetail](
    [ID] [bigint] IDENTITY NOT NULL
    [RecordID] [numeric](18, 0) NOT NULL,
    [TableName] [varchar](30) NOT NULL,
    [TotalRecords] [int] NULL,
    [ArchivedRecords] [int] NULL,
 CONSTRAINT [PK_tblArchLogDetail] PRIMARY KEY CLUSTERED 
(
    [ID] ASC,
    [RecordID] ASC,
    [TableName] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

如果这两个解决方案都无法解决，那么您还需要其他详细信息才能回答此问题。
