Question

我创建了一个查询给定服务器/数据库的函数，我尝试将数据输出到以后可以使用的持久数据集中。问题是数据集在输出时以某种方式转换为数组。正如您在脚本中看到的，我在函数外部创建了一个数据集，但是当我将函数结果传递给它时，它会变为数组

[CmdletBinding()]
param(
[parameter(mandatory = $true,helpmessage = "Enter envrionment name to create tdp files for. Eg 'LTS'")]
[string]$environment, 
[parameter(mandatory = $true,helpmessage = "Enter a log file desination and name eg. \\torvdb954\dba\refresh_output.txt" )]
[string]$logFile
)

"" > $logFile 

function Get-SQLdata 
($SQlServerName, $SQlDBName,$SQlQuery,$FLogfile)
{
        Try
        {
            $SqlConnection = New-Object System.Data.SqlClient.SqlConnection
            $SqlConnection.ConnectionString = "Server = $SQlServerName; 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) 
            return $Dataset.tables[0] 

        }
        Catch
        {
            "Error connecting to: " + $SQlServerName >> $logFile
            $_.ToString() >> $logFile
            $_.ToString()
            break
        }
        finally
        {
             $SqlConnection.Close()
        }

}

#control table data set
#declare your dataset outside the function so it is persisted
$Dataset = New-Object System.Data.Dataset
$Dataset.GetType()
$CtrlSqlQuery = “select distinct instanceName,databaseName from pega_refresh_control where environment = '" + $environment + "'" 
$Dataset = Get-SQLdata -SQlServerName 'torvdb954' -SQlDBName 'DBA_pega_refresh' -FLogfile $logFile -SQlQuery $CtrlSqlQuery 
$Dataset.GetType()
$Dataset.tables[0]
