Copy query to create table dbeaver3/19/2024 But for large tables as in our situation its much slower!īelow you see the queries we used to undublicate the table of AIS data. You can then copy that statement and change the identfier TAB1 to TAB2. This returns a create table statement for TAB1 (in schema < schemaname >). Lucky for us PostgreSQL supports just like MySQL a way to ignore these inserts.įor small tables the DELETE approach is faster then the INSERT approach. set long 100000 select dbmsmetadata.getddl TABLE, TAB1, ) from dual.Ofcourse these inserts will fail as soon as it tries to insert a not unique value. Now select a task type from the list, enter a name and description, and click on the Next button. It got trimmed a lot in the migration, for instance 10 years of data chopped down to 3, to name a few. For us the only way to undublicate all results was to create a new table, add a unique constraint on this table, and insert all data from the original table into the new table. Go to Database -> Tasks -> Create new task. 7 We recently migrated a large DB2 database to a new server. For small tables its faster to use the DELETE approach. It will take days before such query gives results if you dont run out of memory before that happens. The most simple solution, creating a query that finds all dublicates and deletes them is not suitable for such huge amount of data. So if you work alot with PostgreSQL and looking for a free SQL client take a look at this one. In my case it crashed or showed unexpected behaviour with PostgreSQL. Another excellent free SQL client but not that good with PostgreSQL database. Go through: Window -> Preferences -> User Interface -> Keys. Remember that you can always change the keyboard shortcut in the DBeaver settings. It will help you work in DBeaver faster and more efficiently. Figure 1: DBeaver | Free Universal SQL Client My favorite PostgreSQL clientīefore we start, I recently discovered that DBeaver is an excellent and free to use Universal SQL Client. Here is a complete list of default hotkeys in DBeaver UI for Windows, Linux, and macOS users.
