![]() The next step will be about how to use the MariaDB MaxScale GUI. MaxScale 2.5 includes a smart GUI that enables easily monitoring and configuring MaxScale on live traffic. We can rely on MariaDB MaxScale capabilities to remove and update the syntax on live queries. So what can be done about removing the BYTE keyword? The BYTE value is not recognized on the MariaDB client with Oracle compatibility mode. It again returns an error, but it is a different error. Version for the right syntax to use near 'BYTE), "LAST_NAME" VARCHAR2(50 BYTE), "ADDRESS1" VARCHAR2(128 BYTE))' at line 1 Try and create the same table again: MariaDB > CREATE TABLE "customers" ( Enable Oracle compatibility modeĬhange session SQL_MODE to Oracle compatibility mode: SET SESSION sql_mode='ORACLE' ![]() Many items prevent this creation, for example, the double quotes. This syntax can’t be recognized by default on the MariaDB client. Version for the right syntax to use near '"customers" ("CUST_ID" NUMBER(8,0), "FIRST_NAME" VARCHAR2(50 BYTE), "LAST_NAM.' at line 1 Let’s try to create a simple table with Oracle syntax while using the default SQL_MODE: MariaDB > CREATE TABLE "customers" (ĮRROR 1064 (42000): You have an error in your SQL syntax check the manual that corresponds to your MariaDB server +-+-+ Try to create a table with Oracle syntax | sql_mode | STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION | In our example, it is showing the default configuration of the SQL_MODE variable: +-+-+ Verify the current SQL mode from a Linux terminal: sudo mariadb -e "show global variables like 'sql_mode' " Verify the current SQL MODEīecause variables vary and can be adjusted by external software, it’s worth double checking that SQL_MODE is running. In the “New Migration” section, you can choose the database that you’d like to migrate from and get a customized migration assessment to help you evaluate and plan for your migration project. The Migration Portal has a variety of resources to assist you in migrating to MariaDB. SQL_MODE - MariaDB Enterprise documentationīefore digging into the data and structure, MariaDB recommends running a migration assessment in the “ Migration Portal” within the MariaDB customer portal.Getting started with the MariaDB MaxScale GUI.Install MariaDB Enterprise Server and Enterprise Backup.See the MariaDB Enterprise documentation for complete installation instructions: MaxScale configuration will be created with the help of the MaxScale GUI.īecause installations vary, I haven’t included full instructions here for installing MariaDB Enterprise Server and MariaDB MaxScale. The migration process detailed here relies on MariaDB Enterprise Server and MariaDB MaxScale. I’ll demonstrate how the capabilities offered by MariaDB MaxScale, our smart database proxy, and the compatibility mode of MariaDB Enterprise Server greatly simplify migration.Ĭompatibility mode is available for on-premises deployments and also in MariaDB SkySQL for cloud deployments. This blog walks you through the major steps required to migrate easily from Oracle to MariaDB. In the same way, MariaDB offers compatibility features permitting easy migration from Oracle, SQL Server, Postgres and so many others to MariaDB in a few steps without an application rewrite. Deployed in minutes for transactional, analytical or hybrid use cases at any scale, MariaDB delivers unmatched operational agility without sacrificing key enterprise features such as real ACID compliance and full SQL. For example, our pluggable, purpose-built storage engines support work that previously required a variety of specialized databases. ![]() With MariaDB Enterprise, organizations can depend on a single complete database for all their needs, whether on commodity hardware or their cloud of choice.
