sql-server - Powershell SQL 服务器更新查询

Question

我正在尝试连接到 Microsoft SQL 数据库并将更改字段 = 的任何记录更新为“x”。我可以查询数据库，但是当我尝试进行更新时，我收到了这个错误：

Fill : Exception calling "Fill" with "1" argument(s): "Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding."

这是我正在使用的脚本：

#Create SQL Connection
$con = new-object "System.data.sqlclient.SQLconnection"

#Set Connection String
$con.ConnectionString =(“Data Source=server;Initial Catalog=IDCards;Integrated Security=SSPI”)
$con.open()

$sqlcmd = new-object "System.data.sqlclient.sqlcommand"
$sqlcmd.connection = $con
$sqlcmd.CommandTimeout = 600000
#$sqlcmd.CommandText = “select * from tblPhotoID where changed = 'X'”
$sqlcmd.CommandText = “UPDATE dbo.tblPhotoID SET Changed = '1' WHERE Changed ='X'”
$adapter = New-Object system.data.sqlclient.sqldataadapter ($sqlcmd.CommandText, $con)
$set = New-Object system.data.dataset
$adapter.Fill($set)

目前大约有 4000 条记录将被更新。该脚本在超时前运行大约 30 秒。我尝试增加命令超时并得到相同的结果。

您的更新语句不会返回记录集，因此没有任何内容可以填充数据集。相反，您想尝试以下操作：

#Create SQL Connection
$con = new-object "System.data.sqlclient.SQLconnection"

#Set Connection String
$con.ConnectionString =(“Data Source=sb-inft-orange.ads.iu.edu;Initial Catalog=IDCards;Integrated Security=SSPI”)
$con.open()

$sqlcmd = new-object "System.data.sqlclient.sqlcommand"
$sqlcmd.connection = $con
$sqlcmd.CommandTimeout = 600000
$sqlcmd.CommandText = “UPDATE dbo.tblPhotoID SET Changed = '1' WHERE Changed ='X'”
$rowsAffected = $sqlcmd.ExecuteNonQuery()

在您的代码中，您使用$adapter.Fill($set)了仅供参考，它用于在数据集中添加行以匹配数据源中的行。相反，您可以使用$adapter.Update($Set)我认为这将解决您的问题。你也可以使用$sqlcmd.ExecuteNonQuery()

#Create SQL Connection

$con = new-object "System.data.sqlclient.SQLconnection"
#Set Connection String
$con.ConnectionString =(“Data Source=sb-inft-orange.ads.iu.edu;Initial 
Catalog=IDCards;Integrated Security=SSPI”)
$con.open()

$sqlcmd = new-object "System.data.sqlclient.sqlcommand"
$sqlcmd.connection = $con
$sqlcmd.CommandTimeout = 600000
$sqlcmd.CommandText = “UPDATE dbo.tblPhotoID SET Changed = '1' WHERE Changed ='X'”
$sqlcmd.ExecuteNonQuery()

$cn = New-Object System.Data.SqlClient.SqlConnection ( "Integrated Security=SSPI;Persist Security Info=False;Initial Catalog.......)
$q = "select ...  from .. "
$da = New-Object System.Data.SqlClient.SqlDataAdapter($q, $cn)
$da.SelectCommand.CommandTimeout = 60
