Introduction

JDBC Datalist Action allows you to perform SQL queries on one (a row action) or more records (a bulk action) in your datalist. You can specify which database to perform the SQL function, either the current Joget database (default datasource) or a custom datasource (external database).

JDBC Datalist Action can be used to delete records or perform an update on one or more records based on user selection in the datalist checkboxes.

Datasource
  • Custom Datasource - setup to connect to an external database, has additional configuration.
  • Default Datasource - connect to the Joget database.

  • By selecting Default Datasource, the database your Joget is currently using will be selected.

Custom JDBC Driver

Custom JDBC Driver. This field is required when Custom Datasource is selected in Datasource above.
Example: com.mysql.jdbc.Driver

Custom JDBC URL

Custom JDBC URL. This field is required when Custom Datasource is selected in Datasource above.
Example: jdbc:mysql://localhost/jwdb?characterEncoding=UTF8&useSSL=false

Custom JDBC Username

Custom JDBC Username. This field is required when Custom Datasource is selected in Datasource above.

Custom JDBC Password

Custom JDBC Password. This field is required when Custom Datasource is selected in Datasource above.

Test the connection parameters

Click on the "Test Connection" button at the bottom of the page to quickly test out your configurations.

Query

Insert your SQL statement here. Use syntax like {id} in query to inject the selected row key. Use {uuid} to generate a unique id (or primary key). Examples:

Example
INSERT INTO
   app_fd_sample (id, c_clicked) 
VALUES
   (
      {uuid}, {id} 
   )
Example
UPDATE
   app_fd_sample 
SET
   c_clicked = CONCAT(c_clicked, ',', {id}) 
WHERE
   id = {id}
Example
DELETE
FROM
   app_fd_myTable 
WHERE
   id = {id}

Table & Column Naming

For database tables created by Joget Forms, Joget adds a "c_" in front of table column names and "app_fd_" in front of database table names.

How it works?

The special parameters {id} and {uuid} will be replaced with actual values through the use of PreparedStatement. As you can see from the example above, there is no need to encapsulate both of these special keywords with quotes.
