After the database connection is successfully established, the next step is to select the database table as the data input source, click "Get query SQL", then select the corresponding database table, and execute in the order shown below.
After selecting the database table, we can also use the SQL statement in the corresponding input box to query the data we want as the input source of the data. This is still relatively flexible. After determining the SQL statement, it is best to preview the data See if you can guarantee the accuracy of the data.
Compare the data in the table with the preview data. The table input has been completed here, and you can proceed to the following steps.
