    Show only tables under the specified database/schemaWhen this option is selected and the database field is not empty, only tables under this database will be displayed
  4. After filling in the parameters, click the Validate button to get the validation result (this checks the connectivity between HENGSHI SENSE and the configured data connection; you cannot add the connection if validation fails).

  5. After validation passes, Allow write operations and Support uploading files to specified path will be enabled and can be optionally turned on.

  6. Click Execute Preset Code to pop up the preset code for this data source, then click the execute button.

  7. Click the Add button to add the GBase 8a connection.
