使用Force在Windows上导入大型MySQL .sql文件

Question

I would like to import a 350MB MySQL .sql file on a Windows 7 machine. I usually do this by using

mysql -uuser -p -e "source c:/path/to/file.sql" database

since < doesn't work in Powershell.

My .sql file has an error in it this time. I'd prefer to just skip the bad row and continue the import. How can I force the import to continue on Windows?

On a unix/linux based system, I could use

mysql --force ... < file.sql

but --force doesn't seem to work with the -e "source ..." command (understandably so).

Thanks, Mike

Answer 1

You're probably going to have to have Powershell execute this in the standard console in order to use < properly. Technically you could use get-content and pipe the output to mysql , but I've always found that to be slow, and it somehow still keeps the file contents in memory of the Powershell session.

This is how I would execute it from the Powershell prompt (changed file path to include spaces to demonstrate inner quotes, just in case):

cmd /C 'mysql -uuser -p --force < "C:\path\with spaces\to\file.sql"'

[GC]::collect() would apparently clear it up the memory, but you can't do that until after it's done anyway. When it comes to mysql and mysqldump , I don't bother with Powershell. The default encoding used in > is Unicode, making dump files twice as big out of Powershell as out of cmd unless you remember to write | out-file dump.sql -enc ascii | out-file dump.sql -enc ascii instead of > dump.sql .

我建议也看看这个SO答案 ，它利用了source SQL命令：
