有沒有辦法在 Invoke-Sqlcmd 中將 PS 變數鏈接為表？我試過了LEFT JOIN $psvar as p on T1.ID=P.ID
我根據@Cpt.Whale 的建議制作了一個 DataTable，從而更新了腳本。
# Define DataTable Columns
$tbl = New-Object system.Data.DataTable 'tbl_New'
$newcol = New-Object system.Data.DataColumn emplID,([string]); $tbl.columns.add($newcol)
$newcol = New-Object system.Data.DataColumn adGrp,([string]); $tbl.columns.add($newcol)
# Add data from Excel
$exelWkbk = '.\table.xlsx'
$excelQuery = '
SELECT F1 as emplID
,F2 as pcType
FROM [Sheet1$]
'
$queryOutput = Invoke-ExcelQuery $exelWkbk $excelQuery | Select-Object -Skip 1
$queryOutput | ForEach-Object {
$row = $tbl.NewRow()
$row.tmplID = ($_.emplID)
$row.adGrp = ($_.pcType)
$tbl.Rows.Add($row)
}
# Query SQL Data source joining Excel data
$sqlQuery = "
USE SQLDATABASE;
DECLARE @today as date = GETDATE();
SELECT emp.USER_ID
,wt.HOST
,a.pcType as DevicModel
FROM workstationTable as wt
JOIN employeeTable as emp on wt.USER_ID = emp.USER_ID
JOIN $tbl as a on emp.USER_ID = a.emplID
WHERE emp.NAME is not NULL
"
Invoke-Sqlcmd -Query $sqlQuery -ServerInstance 'dbName' |
Out-GridView
uj5u.com熱心網友回復：
Powershell 沒有用于執行不同資料集的 SQL 樣式連接的內置函式。您可以將Select-Object計算屬性用于簡單的查找表型別，但我更喜歡使用基于 LINQ的Join-Object模塊：
# Gather both data sources into separate list variables:
$sqlData = Invoke-Sqlcmd -ServerInstance 'dbName' -Query '
USE SQLDATABASE;
DECLARE @today as date = GETDATE();
SELECT emp.USER_ID,wt.HOST
FROM workstationTable as wt
JOIN employeeTable as emp on wt.USER_ID = emp.USER_ID
WHERE emp.NAME is not NULL'
$excelData = Invoke-ExcelQuery $exelWkbk $excelQuery | Select-Object -Skip 1
# join the lists on a specific property
$joined = Join-Object -Type AllInLeft `
-Left $sqlData -LeftJoinProperty USER_ID `
-Right $excelData -RightJoinProperty EmplID
$joined | Out-GridView
或者，由于您已經在使用 Excel，因此可以選擇檔案中的 SQL 資料連接。
