   Field	Description
   Connection	The name of the database connection to which the task belongs.
   Database	The database to be changed.
   Table	The table for generating data. In the Mock Data panel, select the table from the drop-down list under Table. The drop-down list displays all the tables in the current instance.
   Mock Data Volume	The volume of data to be generated. In the Mock Data panel, set Mock Data Volume to specify the desired number of data rows to be generated. The default value is 1000. The system can generate up to 1,000,000 rows of data. You can set the value to an integer between 1 and 1000000.
   Batch Size	The size of data processed in a batch. In the Mock Data panel, set Batch Size to specify the number of rows generated that trigger a COMMIT operation. The default value is 200. That is, a commit operation is performed once every 200 rows are generated. The maximum value supported is 500. You can set the value to an integer between 1 and 500.
   Empty Table Before Inserting Mock Data	Specifies whether to empty the table before inserting mock data into it. In the Mock Data panel, select Yes or No under Empty Table Before Inserting Mock Data to specify whether or not to empty the table before inserting mock data.
   Data Conflict Handling Mode	The data conflict handling mode. In the Mock Data panel, specify Data Conflict Handling Mode by selecting a mode from the drop-down list. ODC supports the following modes: Ignore: This option is selected by default. The data conflicting with existing data is not inserted. Overwrite: If a data conflict occurs, the original data is deleted, and the new data is inserted. Terminate: If a data conflict occurs, the data mocking task is terminated.
   Rule Settings	The data generation rules. In the Mock Data panel, the Rule Settings table displays Field Name and Field Type based on the table you selected before. You can specify the data generation rules for the target fields in the Rule and Rule Details columns. The Rule column provides built-in rules based on the field type for you to choose from. The Rule Details column displays the detailed information for the rule that you selected. You can click the edit icon to edit the information.

3. Click Submit. The data mocking task is created.
