How to Overwrite Existing Table Structure?
If you want to overwrite the table definitions, you can specify generate DROP TABLE statements option in SQLWays. Please see the "Generate the drop table statements" option.
How to Load the Data into Existing Table Structure?
To load the data into existing table structure without recreating it, uncheck the "Generate DDL" option. In this case, SQLWays will transfer only data.
You can find this option on the “Specify DDL and Data Options” page. You just need to click on “Tables” branch and select “Generation Options” in the dropdown box of the “DDL” tab. After that please uncheck “Generate DDL” option and run the migration. In this case SQLWays Wizard tool will extract, convert and load only data, without the objects definitions.
Also before running the migration please check whether the “Export Data” option is switched on. To do that, please click the “Data” tab on the same page:
Please note, when running data only migration, you need to be sure that there are no constraints in the database that will not allow to push the data into tables in your target database. Otherwise, you will have to disable such constraints in your database before the migration and enable them after the migration process is finished.
