Querying Sql Server

Some examples from Google

$SQLDBName = "MyDBName"
$SqlQuery = "select * from authors WHERE Name = 'John Simon'"
 
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server = $SQLServer; Database = $SQLDBName; Integrated Security = True"
 
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.CommandText = $SqlQuery
$SqlCmd.Connection = $SqlConnection
 
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd
 
$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)
 
$SqlConnection.Close()
 
clear
 
$DataSet.Tables[0]

---

$SQLDBName = “somedb”
$SqlQuery = ‘EXEC [dbo].[usp_mystoredprocedure] ”’ + $parameter1 + ”’, ”’ + $parameter2 + ””
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = “Server=$SQLServer;Database=$SQLDBName;Integrated Security=True”
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.CommandText = $SqlQuery
$SqlCmd.Connection = $SqlConnection
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd
$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)
$SqlConnection.Close()
foreach ($row in $DataSet.Tables[0].Rows)
{ 
$Drive = $row[1].ToString().Trim()
$Threshold = $row[2].ToString()
$MountPoint = $row[3].ToString().Trim()
}
