MySQL SQL Migration

DSC supports the migration from MySQL to GaussDB(DWS), including the migration of schemas, DML, queries, system functions, and PL/SQL.

Performing MySQL Migration on Linux

Run the following command on Linux to start the migration. You need to specify the source database, input and output folder paths, and log paths. The application language is SQL.

./runDSC.sh
--source-db MySQL 
[--input-folder <input-script-path>] 
[--output-folder <output-script-path>]
[--application-lang SQL] 
[--conversion-type <conversion-type>] 
[--log-folder <log-path>]

During the execution of DSC, the migration summary, including the progress and completion status, is displayed on the console.

./runDSC.sh --source-db MySQL --input-folder /opt/DSC/DSC/input/mysql/ --output-folder /opt/DSC/DSC/output/ --application-lang SQL --conversion-type BULK --log-folder/opt/DSC/DSC/log/
