I have a file sql.gz that is a big MySQL dump, so I do not want to extract it when importing.
I would also like to execute a command before the dump get’s imported. In my case I want to disable binary logging for the session:
SET sql_log_bin = 0;
Here is how this may be done in shell:
{ echo 'SET sql_log_bin = 0;' ; gzip -dc sql.gz ; } | mysql
I didn’t test it with huge sql.gz files, I’m not sure if the performance is different than executing gzip -dc sql.gz directly.
