I want to import a sql file of approx 12 mb. But its causing problem while loading. Is there any way to upload it without splitting the sql file ?
Try to import it from mysql console as per the taste of your OS.
mysql -u {DB-USER-NAME} -p {DB-NAME} < {db.file.sql path}
or if it's on a remote server use the -h flag to specify the host.
mysql -u {DB-USER-NAME} -h {MySQL-SERVER-HOST-NAME} -p {DB-NAME} < {db.file.sql path}
