Question

所以我的脚本差不多了，但我在插入带引号的变量时遇到了麻烦。

以下是代码，具体请看$sqlresult。我用单引号将它显示出来，所以显然它只是作为文本输入字符串error[0]，我希望让它调用变量和索引的那一部分。

#error handle
if ($error)
    {
#Assemble the Query
    $sqlresult = '$error[0]'
    $sqlcontext = ($strfilename + ' ' + $content.length + ' bytes')
    $strquery = 
    "INSERT INTO [logs].[dbo].[EventLog] (SourceID, Started, Completed, Result, Context, Machine)
        values (50,'$starttime','$endtime','$sqlresult','$sqlcontext','1sl-den-db03-CAFEEDSCRIPT')"
#Create Command and Execute.
    $sqlCommand = $sqlConnection.CreateCommand()
    $sqlCommand.CommandText = $strQuery
    $sqlCommand.ExecuteNonQuery()

双引号使脚本返回

Exception calling "ExecuteNonQuery" with "0" argument(s): "Incorrect syntax near 'calling'.
Incorrect syntax near the keyword 'with'. If this statement is a common table expression, an xmlnamespaces clause or a change tracking context clause, the previous statement must be terminated with a 
semicolon."
At line:40 char:5
+     $sqlCommand.ExecuteNonQuery()
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : SqlException

我基本上已经学会了＃哟哟，你的sql语句是有效的！＆＃34;

我的猜测是我必须在查询中使用sqlresult变量做一些事情？我不确定。

$Error[0]总是有回报，前提是它不是空的，也许你要找的是$sqlresult = $Error[0].Exception.Message

如果您在catch块中处理此问题，可以执行$sqlresult = $_.Exception.Message

Powershell引号
