Question

我不知所措。我正在尝试将csv中的列导入现有数据表。我相信这样做的最好方法是使用sqlbulkcopy进行列映射，但我无法解决这个问题。我使用下面的脚本与out-datatable函数进行列映射，即使它似乎插入数据，当我运行查询时，我找不到它。我做错了什么？

 import-module .\functions.psm1

# Database variables 
$sqlserver = "Db-test-dev\sql2008" 
$database = "Employees" 
#$table = "dbo.tblPersonal" 
$csvfile = "C:\temp\cidb_test.csv" 

 $SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.connectionstring = "Data Source=$sqlserver;Integrated Security=true;Initial Catalog=$database;" 

$CSVDataTable = Import-Csv ‘$csvfile’ | Out-DataTable

$sqlBulkCopy = New-Object (“Data.SqlClient.SqlBulkCopy”) -ArgumentList $SqlConnection
$sqlBulkCopy.DestinationTableName = “dbo.tblpersonal”

$ColumnMap1 = New-Object System.Data.SqlClient.SqlBulkCopyColumnMapping(1, 1)
$ColumnMap2 = New-Object System.Data.SqlClient.SqlBulkCopyColumnMapping(2, 2)
#$ColumnMap3 = New-Object System.Data.SqlClient.SqlBulkCopyColumnMapping(2, 3)
$sqlBulkCopy.ColumnMappings.Add($ColumnMap1)
$sqlBulkCopy.ColumnMappings.Add($ColumnMap2)
#$sqlBulkCopy.ColumnMappings.Add($ColumnMap3)

$SqlConnection.Open()
$sqlBulkCopy.WriteToServer($CSVDataTable)
$SqlConnection.Close()

使用批量复制添加了列映射

$ColumnMap1 = New-Object System.Data.SqlClient.SqlBulkCopyColumnMapping('SSN','SSN')
$ColumnMap2 = New-Object System.Data.SqlClient.SqlBulkCopyColumnMapping('LastName', 'LastName')
$ColumnMap3 = New-Object System.Data.SqlClient.SqlBulkCopyColumnMapping('MiddleName','MiddleName')
$ColumnMap4 = New-Object System.Data.SqlClient.SqlBulkCopyColumnMapping('FirstName','FirstName')
$ColumnMap5 = New-Object System.Data.SqlClient.SqlBulkCopyColumnMapping('PreferredName','PreferredName')
$ColumnMap6 = New-Object System.Data.SqlClient.SqlBulkCopyColumnMapping('WorkPhone','WorkPhone')
$ColumnMap7 = New-Object System.Data.SqlClient.SqlBulkCopyColumnMapping('Email','Email')
$ColumnMap8 = New-Object System.Data.SqlClient.SqlBulkCopyColumnMapping('EmpType','EmpType')
$ColumnMap9 = New-Object System.Data.SqlClient.SqlBulkCopyColumnMapping('HireDate', 'HireDate')
$ColumnMap10 = New-Object System.Data.SqlClient.SqlBulkCopyColumnMapping('ACID','ACID')
$ColumnMap11 = New-Object System.Data.SqlClient.SqlBulkCopyColumnMapping('OPID','OPID')
$ColumnMap12 = New-Object System.Data.SqlClient.SqlBulkCopyColumnMapping('Floor','Floor')
$ColumnMap13 = New-Object System.Data.SqlClient.SqlBulkCopyColumnMapping('Department','Department')
$ColumnMap14 = New-Object System.Data.SqlClient.SqlBulkCopyColumnMapping('Division','Division')
$BulkCopy.ColumnMappings.Add($ColumnMap1)
$BulkCopy.ColumnMappings.Add($ColumnMap2)
$BulkCopy.ColumnMappings.Add($ColumnMap3)
$BulkCopy.ColumnMappings.Add($ColumnMap4)
$BulkCopy.ColumnMappings.Add($ColumnMap5)
$BulkCopy.ColumnMappings.Add($ColumnMap6)
$BulkCopy.ColumnMappings.Add($ColumnMap7)
$BulkCopy.ColumnMappings.Add($ColumnMap8)
$BulkCopy.ColumnMappings.Add($ColumnMap9)
$BulkCopy.ColumnMappings.Add($ColumnMap10)
$BulkCopy.ColumnMappings.Add($ColumnMap11)
$BulkCopy.ColumnMappings.Add($ColumnMap12)
$BulkCopy.ColumnMappings.Add($ColumnMap13)
$BulkCopy.ColumnMappings.Add($ColumnMap14)
