エクスポートウィザードでは、一度に1つしか許可されません。 PowerShellスクリプトを使用して、すべてのテーブルをcsvにエクスポートしました。役立つ場合は、これを試してください。
$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
}
