Data Options


Advanced

 

CheckBox Shared connection within database*

Select this option to disable creation of a separated connection for each data view. Enabling this option is recommended if maximum allowed number of connections is too low. It is also recommended to enable the Auto commit option available in the Data Options section of the Database Registration info.

 

CheckBox Asynchronous query execution

Check this option to allow executing a query/getting object data in the background mode.

 

CheckBox Perform data filtration on client in data view*

If enabled, the data are filtered by SQL Manager for Oracle (on the client side).

If disabled, SQL filter is used in data view. In this case filtering is performed on the Oracle server with the help of the WHERE clause used in SQL query.

 

Load visible rows mode if records more than...*

Set this option to switch to the Load visible rows mode when the number of records in the dataset exceeds the specified value.

 

String fields width (chars)

Using this option you can limit string fields width that may improve performance on large datasets.

 

Environment Options - Grid - Data Options

 

 

Default grid mode

 

RadioButton Load all rows*

The grid loads all records from a dataset. This option increases the grid performance by reloading only changed dataset records when updating.  In this mode all features (automatic sorting, filtering and summary calculations) are available.

 

RadioButton Load visible rows*

The grid loads only a fixed number of dataset records into memory. This option minimizes dataset loading time. Automatic sorting, filtering, summary calculations are not available in this mode.

 

The Default grid mode options allow you to define the grid mode which will be used by default.

With the Load all rows option enabled, when loading data, all the records are loaded into grid buffers. In this mode opening the tables with many records may take a considerable amount of time. But in this case you can make use of some advantages: in the filter drop-down list the column headers are displayed with the values for quick filtering; it is possible to open several sub-levels at the same time when viewing data in master-detail view, etc.

In case opening and other operations with an object consisting of many records takes sufficient time, the Load visible rows mode should be used instead. It can be set individually for each table and saved between sessions (can be set through the context menu of the grid).
