powershell:如何通过 invoke-sqlcmd 捕获错误原因? [英] powershell:how to catch the error cause by invoke-sqlcmd?

问题描述

如果有任何问题，我想捕获 invoke-sql.但是当我运行以下命令时，如果 $sql 无效，则无法捕获.如何捕捉这个异常?

I want to catch the invoke-sql if there is anything wrong. But when I run the following command, and if the $sql is invalid, it can't be caught. How to catch this exception?

 try {
     Invoke-Sqlcmd -Query $sql -ServerInstance t1 -database db -QueryTimeout 65535 -ErrorAction 'Stop'
   } catch{
      "error when running sql $sql"
   }

推荐答案

我没有问题，使用名为 test.ps1 的脚本

I have no issue, using a script called test.ps1

add-pssnapin SqlServerCmdletSnapin100
get-host
$sql = "selects * from syscomments"
$server = ""
$database = ""
$username = ""
$password = ""
try {
    Invoke-Sqlcmd -Query $sql -ServerInstance $server -database $database -QueryTimeout 65535 -ErrorAction 'Stop' -username $username -password $password
} catch {
  "error when running sql $sql"
  Write-Host($error)
}

和输出

PS C:\> .\test.ps1

Incorrect syntax near '*'.

您使用的是什么输入参数，您使用的是 powershell 1 还是 2?
