问题 I was wondering if I can prevent mysqldump inserting this commands /*!50017 DEFINER=`root`@`localhost`*/ Or if I have to do it afterwards with sed, for example Thanks! 回答1: This issue has been around since 2006 with no sign of ever being fixed. I have, however, piped it through grep (linux only) to trim out the definer lines before writing the dump file: mysqldump -u dbuser -p dbname | grep -v 'SQL SECURITY DEFINER' > dump.sql A bit of a mouthful (or keyboardful?) but I think it's the only

问题 Since I'm making a full backup of my entire debian system, I was thinking if having a copy of /var/lib/mysql directory is a viable alternative to dumping tables with mysqldump. are all informations needed contained in that directory? can single tables be imported in another mysql? can there be problems while restoring those files on a (probably slightly) different mysql server version? 回答1: Yes Yes if the table is using the MyISAM (default) engine. Not if it's using InnoDB. Probably not, and

问题 I have a 1TB table (X) that is a pain to backup. The table X contains historical log data that is not often updated after creation. We usually only access a single row at a time, so performance is still very good. We currently make nightly full logical backups, and exclude X for the sake of backup time and space. We do not need historical backups of X, since the log files from which it is populated are backed up themselves. However, recovery of X by re-processing of the log files would take

问题 I need to backup a MySQL database from an NSIS installer. I am missing something trivial in the scripts I tried: nsExec::Exec '"$mySqlDirectory\bin\mysqldump.exe" --user=$username --password=$password --routines $dbName --execute="source D:\$dbName.sql"' $0 nsExec::Exec '"$mySqlDirectory\bin\mysqldump.exe" --user=$username --password=$password --routines $dbName --execute="D:\$dbName.sql"' $0 nsExec::Exec '"$mySqlDirectory\bin\mysqldump.exe" --user=$username --password=$password --execute="-

问题 We want to have our test servers databases updated from our production server databases on a nightly basis to ensure we're developing on the most recent data. We, however, want to ensure that any fn, sp, etc that we're currently working on in the development environment doesn't get overwritten by the backup process. What we were thinking of doing was having a prebackup program that saves objects selected by our developers and a postbackup program to add them back in after the backup process

问题 Hypothetical question: If a maintenance plan is scheduled to run a full backup of several databases while they're online, and during this time other jobs are scheduled to run (stored procedures, SSIS packages etc), what happens to these jobs during the backup? I'm guessing either: The job is paused until the backup is completed, then they're run in the same order they were scheduled to. Or SQL Server works out what tables will be affected by each scheduled job and backs them up after the job
