如何利用powershell 访问sqlserver

下面简单一个脚本实现访问sqlserver,支持所有版本的SQLserver。

你是否需要连接数据库？这里有一段代码演示如何查询和获取SQL数据，只需非常简单正确的配置你的账户信息、服务器地址及SQL语句就行：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

$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

后来我又完善了这个代码，详细代码注释如下：

#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()
