|Result set page size|| The number of table rows to be shown at a time, on one "page". Here is an example when this number is set to 2: |
If you don't want to limit the number of rows displayed simultaneously, specify zero (0).
|Result set prefetch size|| Data from databases are retrieved in chunks. The number in this field defines the number of rows in such chunks. |
A bigger number means fewer IDE - DB round trips but more memory for storing a chunk.
|Filter history size||The number of most recently used filtering conditions to memorize for a table in the table editor. Here is an example when this number is set to 2. (The filter history box contains two most recently used conditions.)|
|Max LOB length (bytes)||The maximum size of a binary large object to be loaded in bytes.|
|Data Modification / Submit changes immediately|| When this options is off, the changes you make to data in a table are accumulated in PyCharm unless you carry out the Submit command ( on the toolbar, Submit in the context menu or Ctrl+Enter). Before you submit the changes, you can revert them ( on the toolbar, Revert in the context menu or Ctrl+Z). |
When this option is on, the changes are submitted right away.
