매개 변수
- sqlCommands
유형: StringCollection

예
C#
ServerConnection conn = new ServerConnection();
conn.DatabaseName = "AdventureWorks2012";
StringCollection sqlQuery = new StringCollection();
sqlQuery.Add("SELECT Name FROM Production.Location");
sqlQuery.Add("SELECT CostRate FROM Production.Location");
Object[] costData = conn.ExecuteScalar(sqlQuery);
for (int i = 0; i < costData.Length; i++)
{
Console.WriteLine(costData[i].ToString());
}
PowerShell
$conn = new-object Microsoft.SqlServer.Management.Common.ServerConnection
$conn.DatabaseName = "AdventureWorks2012"
$sqlQuery = new-object System.Collections.Specialized.StringCollection
$sqlQuery.Add("SELECT Name FROM Production.Location")
$sqlQuery.Add("SELECT CostRate FROM Production.Location")
$costData = $conn.ExecuteScalar($sqlQuery)
$i = 0
while ($i -le $costData.Length)
{
Write-Host $costData[$i]
$i++
}
