Migrate your My. SQL database using dump and restore in Azure Database for My. SQLThis article explains two common ways to back up and restore databases in your Azure Database for My. SQLDump and restore from the command line using mysqldump Dump and restore using PHPMy. The SQLite project provides a simple commandline utility named sqlite3 or sqlite3. Windows that allows the user to manually enter and execute SQL statements. Admin Before you begin. To step through this how to guide, you need to have Use common utilities and tools such as My. SQL Workbench, mysqldump, Toad, or Navicat to remotely connect and restore data into Azure Database for My. SQL. Use such tools on your client machine with an internet connection to connect to the Azure Database for My. SQL. Use an SSL encrypted connection for best security practices, see also Configure SSL connectivity in Azure Database for My. SQL. You do not need to move the dump files to any special cloud location when migrating to Azure Database for My. SQL. Common uses for dump and restore. Articulos/Eliminar_fichero_base_datos_SQLServer_Remove_file.jpg' alt='Delete Sql Dump Files' title='Delete Sql Dump Files' />You may use My. SQL utilities such as mysqldump and mysqlpump to dump and load databases into an Azure My. SQL Database in several common scenarios. In other scenarios, you may use the Import and Export approach instead. Use database dumps when you are migrating the entire database. This recommendation holds when moving a large amount of My. SQL data, or when you want to minimize service interruption for live sites or applications. Make sure all tables in the database use the Inno. DB storage engine when loading data into Azure Database for My. SQL. Azure Database for My. SQL supports only Inno. DB Storage engine, and therefore does not support alternative storage engines. If your tables are configured with other storage engines, convert them into the Inno. DB engine format before migration to Azure Database for My. SQL. For example, if you have a Word. Press or Web. App using the My. ISAM tables, first convert those tables by migrating into Inno. DB format before restoring to Azure Database for My. SQL. Use the clause ENGINEInno. DB to set the engine used when creating a new table, then transfer the data into the compatible table before the restore. INSERT INTO innodbtable SELECT FROM myisamtable ORDER BY primarykeycolumns. To avoid any compatibility issues, ensure the same version of My. SQL is used on the source and destination systems when dumping databases. For example, if your existing My. SQL server is version 5. Azure Database for My. SQL configured to run version 5. The mysqlupgrade command does not function in an Azure Database for My. SQL server, and is not supported. If you need to upgrade across My. The Hanging Gardens Of Beatenberg. SQL versions, first dump or export your lower version database into a higher version of My. SQL in your own environment. Then run mysqlupgrade, before attempting migration into an Azure Database for My. This chapter explains what endtoend application tracing is, and how to generate and read trace files.

Some of the common SQL Query tools like Squirrel Sql can have issues when it tries to return large result sets. This seems to be because it needs to hold them in memory. SQL. To optimize performance, take notice of these considerations when dumping large databases Use the exclude triggers option in mysqldump when dumping databases. Exclude triggers from dump files to avoid the trigger commands firing during the data restore. Use the single transaction option to set the transaction isolation mode to REPEATABLE READ and sends a START TRANSACTION SQL statement to the server before dumping data. Dumping many tables within a single transaction causes some extra storage to be consumed during restore. The single transaction option and the lock tables option are mutually exclusive because LOCK TABLES causes any pending transactions to be committed implicitly. To dump large tables, combine the single transaction option with the quick option. Use the extended insert multiple row syntax that includes several VALUE lists. This results in a smaller dump file and speeds up inserts when the file is reloaded. Use the order by primary option in mysqldump when dumping databases, so that the data is scripted in primary key order. Use the disable keys option in mysqldump when dumping data, to disable foreign key constraints before load. Disabling foreign key checks provides performance gains. Enable the constraints and verify the data after the load to ensure referential integrity. Use partitioned tables when appropriate. Load data in parallel. Avoid too much parallelism that would cause you to hit a resource limit, and monitor resources using the metrics available in the Azure portal. Use the defer table indexes option in mysqlpump when dumping databases, so that index creation happens after tables data is loaded. Create a backup file from the command line using mysqldump. To back up an existing My. SQL database on the local on premises server or in a virtual machine, run the following command mysqldump opt u uname ppass dbname backupfile. The parameters to provide are uname Your database username pass The password for your database note there is no space between p and the password dbname The name of your database backupfile. The filename for your database backup opt The mysqldump option For example, to back up a database named testdb on your My. SQL server with the username testuser and with no password to a file testdbbackup. The command backs up the testdb database into a file called testdbbackup. SQL statements needed to re create the database. To select specific tables in your database to back up, list the table names separated by spaces. For example, to back up only table. To back up more than one database at once, use the database switch and list the database names separated by spaces. To back up all the databases in the server at one time, you should use the all databases option. Create a database on the target Azure Database for My. SQL server. Create an empty database on the target Azure Database for My. SQL server where you want to migrate the data. Use a tool such as My. SQL Workbench, Toad, or Navicat to create the database. The database can have the same name as the database that is contained the dumped data or you can create a database with a different name. To get connected, locate the connection information on the Properties page in your Azure Database for My. SQL. Add the connection information into your My. SQL Workbench. Restore your My. SQL database using command line or My. SQL Workbench. Once you have created the target database, you can use the mysql command or My. SQL Workbench to restore the data into the specific newly created database from the dump file. In this example, restore the data into the newly created database on the target Azure Database for My. SQL server. mysql h myserver. Export using PHPMy. Admin. To export, you can use the common tool php. My. Admin, which you may already have installed locally in your environment. To export your My. SQL database using PHPMy. Admin Open php. My. Admin. Select your database. Click the database name in the list on the left. Click the Export link. A new page appears to view the dump of database. In the Export area, click the Select All link to choose the tables in your database. In the SQL options area, click the appropriate options. Click the Save as file option and the corresponding compression option and then click the Go button. A dialog box should appear prompting you to save the file locally. Import using PHPMy. Admin. Importing your database is similar to exporting. Do the following actions Open php. My. Admin. In the php. My. Admin setup page, click Add to add your Azure Database for My. SQL server. Provide the connection details and login information. Create an appropriately named database and select it on the left of the screen.
