mysqldump: Error 2020: Got packet bigger than 'max_allowed_packet' bytes when dumping table
happens, when I do a
mysqldump -u root -p database >dumpfile.sql
I increased max_allowed_packet to the max value already (1073741824) to no avail.
How come that one cannot dump a database with mysqls on board means? Cause may be a longblob in a data row/column which may be maximum size of 4 GB (4294967295 bytes).
Could it be the network transport being used? Would there be another transport?
回答1:
Use below command mysqldump --max_allowed_packet=512M -u root -p database > dumpfile.sql
This will solve your issue
