更改查询输出的默认日期格式

Question

我正在运行一个巨大的PowerShell脚本，该脚本遍历数据库中的每个表和视图，并为每个表/视图创建* .CSV文本文件，其中包含整个数据集。（SELECT * FROM <table/view name>）

DATE或DATETIME的任何列均以MM/DD/YYYY格式产生我需要它们以YYYY/MM/DD

格式出现

有超过1,200个表和视图，因此我无法手动指定每个受影响的列的格式。

我可以在服务器级别更改默认输出格式吗？...还是在数据库级别？...还是在会话级别？

这是我的PowerShell代码：

$server = "myserver"
$database = "mydb"
$tablequery = "SELECT s.name AS schema_name, t.name AS table_name FROM sys.tables t LEFT JOIN sys.schemas s ON s.schema_id = t.schema_id UNION ALL SELECT s.name, v.name FROM sys.views v LEFT JOIN sys.schemas s ON s.schema_id = v.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
$SqlAdapter.SelectCommand.CommandTimeout=600
$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
    $extractFile = "C:\mydb\$($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
}

如果添加此行怎么办：
