How to Import Large Database to MySQL

Hi!

Have a large Access database to transition to MySQL.  Have written VBA code to write the SQL statements (CREATE then INSERT) for all tables and records being converted.  Problem is the file size.  If all data is in a single file, the .sql file is 177 meg.  If I split into 57 separate tables, the largest is still 67 meg.

I'm testing locally on WAMP server.  The MySQL import will only allow 2K (that's K, not Meg) files.

How can I change the MySQL import file size limit?  Does MySQL, in general, have a limit on the file size or number of records that can be imported?

Thanks,
Bruce

Set mySQLs variable 'max_allowed_packet' to '1024M' in your config file, restart and you will be good to go.

I am running several mySQL databases with plenty GBs. This is not the matter.

Ferrosti,

Changed the MySQL "my.ini" file to 1024M, then closed and restarted WAMP.
Still got 'file too large' error when using the MySQL GUI to import.
Was able to resolve, however, by using the MySQL DOS Console and the 'source' command.  Found out elsewhere that it will take unlimited file size.

Thanks for replying, though!

Sorry, I did not see that you try this using a GUI.
Which one are you trying? Web-based or some mySQL Workbench tools or similar?

or move data record by record

MoveTable("Table1");
...
MoveTable("Table99");


proc MoveTable(tableName)
  select from access
  while not eof
    insert into mysql
    goto Next record
    Show Progess, etc
  end;
end;

Add transactions by taste

It would be even faster to export it as .csv and bulk insert into mySQL.
