我有一个 Powershell 脚本,它调用 SQL Server 中的存储过程并将生成的 XML 直接输出到文件中。它适用于较小的测试文件,但会随着完整大小(~1.5gb 文件)而下降。

存储过程工作正常。我可以在 SQL Server 中调用它 - 问题是我必须在 SQL Server 中打开它,然后手动将其保存到文件中,然后编辑该文件以删除换行符。当我运行脚本时,它会在最后尝试删除中间文件时崩溃。但是,当我逐行运行它时,它会落在 invoke-sql 行。

#net use S: "\\processStore\projects"

# Create variables
$SQLquery = "DECLARE @return_value int; EXEC @return_value = [XML].[XMLdata];"
$outpath = "D:\MyDocuments\XML\XML files" 
$outfile = "TestOutput"

# Run the SQL command and store the object to a variable. Need to extend the timeout from the default.
$sql = invoke-sqlcmd -Database 'APP2021' -Query $SQLquery -serverinstance 'statdata' -QueryTimeout 100000

cd C:

# Store the SQL output as an interim text file
$sql.{XML_F52E2B61-18A1-11d1-B105-00805F49916B} | out-file -Filepath "$outpath\$outfile.txt" 

# Remove Linebreaks
(Get-Content "$outpath\$outfile.txt" -Raw).Replace("`r`n","") | Set-Content "$outpath\${outfile}_del.xml" -Force
format-xml "$outpath\${outfile}_del.xml" | Set-Content "$outpath\$outfile.xml" -Force

# Delete interim text files
del "$outpath\$outfile.txt"
del "$outpath\${outfile}_del.xml"

逐行运行时,代码在 invoke-sqlcmd 行出现错误:

invoke-sqlcmd : A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote 
host.)

invoke-sqlcmd -Database 'APP2021' -Query $SQLquery -serverinstance 'statdata' -QueryTimeout 100000
更改为
invoke-sqlcmd -Database 'APP2021' -Query $SQLquery -serverinstance 'statdata' -QueryTimeout 0

设置 QueryTimeout = 0 将防止查询超时
