如何利用powershell 访问sqlserver

$Database  = 'Name_Of_SQLDatabase'
$Server  = '192.168.100.200'
$UserName  = 'DatabaseUserName'
$Password  = 'SecretPassword'
$SqlQuery  = 'Select * FROM TestTable'
# Accessing Data Base
$SqlConnection  = New-Object -TypeName System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Data Source=$Server;Initial Catalog=$Database;user id=$UserName;pwd=$Password"
$SqlCmd  = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.CommandText             = $SqlQuery
$SqlCmd.Connection              = $SqlConnection
$SqlAdapter  = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand       = $SqlCmd
$set  = New-Object data.dataset
# Filling Dataset
$SqlAdapter.Fill($set)
# Consuming Data
$Path = "$env:temp\report.hta"
$set.Tables[0] | ConvertTo-Html | Out-File -FilePath $Path
Invoke-Item -Path $Path 

#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()
