我使用我在SO上找到的函数从SQL服务器检索数据并生成XML。
function Invoke-SQL {
param(
[string] $sqlCommand = $(throw "Please specify a query.")
)
$connectionString = "Data Source=$server;Initial Catalog=$database;user id=$uid;password=$pwd"
$connection = new-object system.data.SqlClient.SQLConnection($connectionString)
$command = new-object system.data.sqlclient.sqlcommand($sqlCommand,$connection)
$connection.Open()
$adapter = New-Object System.Data.sqlclient.sqlDataAdapter $command
$dataset = New-Object System.Data.DataSet
$adapter.Fill($dataSet) | Out-Null
$connection.Close()
$tableOutput = $dataSet.Tables
foreach($row in $tableOutput) {
$xml = $row | ConvertTo-Xml -NoTypeInformation -Depth 1
$xml.InnerXML
}
}
它大部分时间都可以工作,但偶尔会从同一个数据库和表中完全相同的SELECT(范围除外)会抛出以下异常:
Exception calling "Fill" with "1" argument(s): "Incorrect syntax near '>'."
At DBTest.ps1:22 char:18
+ $adapter.Fill <<<< ($dataSet) | Out-Null
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : DotNetMethodException
如何调试哪些行和/或哪些数据使Fill方法中断?

根据评论,这是SQL命令本身。生成SQL命令时,请确保每个变量都经过验证和健全性检查。正如一些评论建议的那样,日志记录查询可以帮助您进行故障排除。
