篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了SQL Server自动化运维系列——批量执行SQL脚本（Power Shell）相关的知识，希望对你有一定的参考价值。

需求描述

一般在生产环境中，在投产的情况下，需要批量的来执行SQL脚本文件，来完成整个投产，如果投产文件比较多的情况下，无疑这是一个比较痛苦的过程，所以本篇通过PowerShell脚本来批量完成。

监控脚本

<#批量执行SQL脚本文件#>
<#===========================================#>
$serverInstance="WUXUEL1" 
$Database="111"
#$userName="sa"
#$password="password01!"
$ScriptPath="C:\powershell\SQLTest\"
$ScriptList="

<#===========================================#>
$n="`n"
$r="`r"
While ($ScriptList.IndexOf($n) -gt 0)
    {$ScriptList=$ScriptList.Replace($n,";")}
While ($ScriptList.IndexOf($r) -gt 0)
    {$ScriptList=$ScriptList.Replace($r,";")}    
While ($ScriptList.IndexOf(" ") -gt 0)    
    {$ScriptList=$ScriptList.Replace(" ","")}
