我正在使用mssql。 插入记录后,我想获取数据的ID。 但我不知道这么做的热情。 我的代码如下。 请给我答案。
var mssql = require('mssql');
mssql.connect(config.mssql, function(err) {
var request = new mssql.Request();
request.query('insert -----'),function(err, data) {
console.log(data);
}
插入工作正常,但控制台日志是[未定义] ....
这是表格的ddl
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo]。[功能](
[id] nvarchar NOT NULL CONSTRAINT [DF_Feature_id] DEFAULT(CONVERT(nvarchar,newid(),(0))),
[createdAt] datetimeoffset NOT NULL CONSTRAINT [DF_Feature_createdAt] DEFAULT(CONVERT(datetimeoffset,sysutcdatetime(),(0))),
[updatedAt] datetimeoffset NULL,
[version] [timestamp] NOT NULL,
[删除] [bit] NULL DEFAULT((0)),
[title] nvarchar NULL,
[text] nvarchar NULL,
[period_from] datetimeoffset NULL,
[period_to] datetimeoffset NULL,
[priority] [float] NULL,
主要密钥非集群
(
[id] ASC
)WITH(STATISTICS_NORECOMPUTE = OFF,IGNORE_DUP_KEY = OFF)
)
GO

使用OUTPUT子句。这是语法的一个例子......
IF OBJECT_ID('RandomTest.dbo.FeatureID_Capture', 'U') IS NOT NULL
DROP TABLE dbo.FeatureID_Capture;
GO
CREATE TABLE dbo.FeatureID_Capture (
Id NVARCHAR(50)
);
GO
IF OBJECT_ID('RandomTest.dbo.Feature', 'U') IS NOT NULL
DROP TABLE dbo.Feature;
GO
CREATE TABLE dbo.Feature (
id NVARCHAR(40) NOT NULL
CONSTRAINT DF_Feature_id
DEFAULT (CONVERT(NVARCHAR(40), NEWID(), (0))),
createdAt DATETIMEOFFSET NOT NULL
CONSTRAINT DF_Feature_createdAt
DEFAULT (CONVERT(DATETIMEOFFSET, SYSUTCDATETIME(), (0))),
updatedAt DATETIMEOFFSET NULL,
version TIMESTAMP NOT NULL,
deleted BIT NULL
DEFAULT ((0)),
title NVARCHAR (10) NULL,
text NVARCHAR (10) NULL,
period_from DATETIMEOFFSET NULL,
period_to DATETIMEOFFSET NULL,
priority FLOAT NULL,
PRIMARY KEY NONCLUSTERED (id ASC)
WITH (STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF)
);
GO
--=======================================================
INSERT dbo.Feature (title, text)
OUTPUT Inserted.id INTO dbo.FeatureID_Capture(Id)
VALUES ('t 1', 'txt 1'), ('t 2', 'txt 22'), ('t 3', 'txt 333');
-------------------------------------
SELECT *FROM dbo.FeatureID_Capture fic;
输出......
