PowerShell 连接 SQL SERVER 数据库进行操作

#配置信息
$Database	= 'DemoDB'
$Server		= '"WIN-AHAU9NO5R6U\DOG"'
$UserName	= 'kk'
$Password	= '123456'

#创建连接对象
$SqlConn = New-Object System.Data.SqlClient.SqlConnection

#使用账号连接MSSQL
$SqlConn.ConnectionString = "Data Source=$Server;Initial Catalog=$Database;user id=$UserName;pwd=$Password"

#或者以 windows 认证连接 MSSQL
#$SqlConn.ConnectionString = "Data Source=$Server;Initial Catalog=$Database;Integrated Security=SSPI;"

#打开数据库连接
$SqlConn.open()

#执行语句方法一
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.connection = $SqlConn
$SqlCmd.commandtext = 'delete top(1) from dbo.B'
$SqlCmd.executenonquery()

#执行语句方法二
$SqlCmd = $SqlConn.CreateCommand()
$SqlCmd.commandtext = 'delete top(1) from dbo.B'
$SqlCmd.ExecuteScalar()

#方法三，查询显示
$SqlCmd.commandtext = 'select name,recovery_model_desc,log_reuse_wait_desc from sys.databases'
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd
$set = New-Object data.dataset
$SqlAdapter.Fill($set)
$set.Tables[0] | Format-Table -Auto

#关闭数据库连接
$SqlConn.close()
