将多个表结果复制到Excel

Question

我有一个海量的SQL查询返回4个表。我能够返回第一个表，但不是其他表，这里是我在下面使用的代码。我正在使用我在网上找到的powershell脚本。我正要通过将$DataSetTable = $DataSet.Tables[0]更改为$DataSetTable = $DataSet.Tables[1]来获得第二张表格，第二张表格是在Excel表格中返回的，但不是第一张。

我怎么能所有的表？

$SQLServer = 'SQLCL01' 
$Database = 'home' 
$SqlQuery = @' Query goes here'@ 

## - Connect to SQL Server using non-SMO class 'System.Data': 
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection 
$SqlConnection.ConnectionString = "Server = $SQLServer; Database = $Database; Integrated Security = True" 

$SqlCmd = New-Object System.Data.SqlClient.SqlCommand 
$SqlCmd.CommandText = $SqlQuery 
$SqlCmd.Connection = $SqlConnection 

## - Extract and build the SQL data object '$DataSetTable': 
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter 
$SqlAdapter.SelectCommand = $SqlCmd 
$DataSet = New-Object System.Data.DataSet 
$SqlAdapter.Fill($DataSet) 
$DataSetTable = $DataSet.Tables[0] 

## --------- Working with Excel ------- ## 

## - Create an Excel Application instance: 
$xlsObj = New-Object -ComObject Excel.Application 

## - Create new Workbook and Sheet (Visible = 1/0 not visible) 
$xlsObj.Visible = 1 
$xlsWb = $xlsobj.Workbooks.Add() 
$xlsSh = $xlsWb.Worksheets.item(1) 

$xlsSh = $xlsWb.Worksheets.Item("Sheet1") 
$xlsSh.Name = "Back date dump" 
$xlsSh = $xlsWb.ActiveSheet 

## - Build the Excel column heading: 
[Array] $getColumnNames = $DataSetTable.Columns | Select ColumnName 

## - Build column header: 
[int] $RowHeader = 1 
foreach ($ColH in $getColumnNames) { 
    $xlsSh.Cells.item(1, $RowHeader).font.bold = $true 
    $xlsSh.Cells.item(1, $RowHeader) = $ColH.ColumnName 
    $RowHeader++ 
} 

## - Adding the data start in row 2 column 1: 
[int] $rowData = 2 
[int] $colData = 1 

foreach ($rec in $DataSetTable.Rows) { 
    foreach ($Coln in $getColumnNames) { 
    ## - Next line convert cell to be text only: 
    $xlsSh.Cells.NumberFormat = "@" 

    ## - Populating columns: 
    $xlsSh.Cells.Item($rowData, $colData) = $rec.$($Coln.ColumnName).ToString() 
    $ColData++ 
    } 
    $rowData++; $ColData = 1 
} 

## - Adjusting columns in the Excel sheet: 
$xlsRng = $xlsSH.usedRange 
$xlsRng.EntireColumn.AutoFit()

遍历集合中的所有表：

$xlsObj = New-Object -ComObject Excel.Application 
foreach ($DataSetTable in $DataSet.Tables) { 
    ... 
}
