Trình hướng dẫn xuất chỉ cho phép mỗi lần một. Tôi đã sử dụng tập lệnh powershell để xuất tất cả các bảng của mình thành csv. Vui lòng thử điều này nếu nó có ích cho bạn.
$server = "SERVERNAME\INSTANCE"
$database = "DATABASE_NAME"
$tablequery = "SELECT schemas.name as schemaName, tables.name as tableName from sys.tables inner join sys.schemas ON tables.schema_id = schemas.schema_id"
#Delcare Connection Variables
$connectionTemplate = "Data Source={0};Integrated Security=SSPI;Initial Catalog={1};"
$connectionString = [string]::Format($connectionTemplate, $server, $database)
$connection = New-Object System.Data.SqlClient.SqlConnection
$connection.ConnectionString = $connectionString
$command = New-Object System.Data.SqlClient.SqlCommand
$command.CommandText = $tablequery
$command.Connection = $connection
#Load up the Tables in a dataset
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $command
$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)
$connection.Close()
# Loop through all tables and export a CSV of the Table Data
foreach ($Row in $DataSet.Tables[0].Rows)
{
$queryData = "SELECT * FROM [$($Row[0])].[$($Row[1])]"
#Specify the output location of your dump file
$extractFile = "C:\mssql\export\$($Row[0])_$($Row[1]).csv"
$command.CommandText = $queryData
$command.Connection = $connection
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $command
$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)
$connection.Close()
$DataSet.Tables[0] | Export-Csv $extractFile -NoTypeInformation
}
Cảm ơn
