PowerShell 技能连载 - 通过连接字符串访问 SQL 数据库

在前一个技能中我们揭示了如何创建一个 SQL Server 的连接字符串。无论您用什么方式创建了这个字符串——假设您已拥有了一个合法的数据库连接字符串,这个例子将演示如何对数据库执行 SQL 命令。

#requires -Version 2

# make sure this is a valid connection string to your database
# see www.connectionstrings.com for reference
$connectionString = 'Provider=SQLOLEDB.1;Password=.topSecret!;Persist Security
 Info=True;User ID=sa;Initial Catalog=test;Data Source=myDBServer\SQLEXPRESS2012'

# make sure this is valid SQL for your database
# so in this case, make sure there is a table called "test"
$sql = 'select * from test'

$db = New-Object -ComObject ADODB.Connection
$rs = $db.Execute($sql)

$results = While ($rs.EOF -eq $false)
    $CustomObject = New-Object -TypeName PSObject
    $rs.Fields | ForEach-Object -Process {
        $CustomObject | Add-Member -MemberType NoteProperty -Name $_.Name -Value $_.Value
$results | Out-GridView
