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

Target database to execute SQL statements on.

Choices:-

  • Custom Datasource
    • JDBC Connection Parameters are needed for this choice.
  • Default Datasource
    • Points to the current database your copy of Joget currently connects to.
Custom JDBC Driver

JDBC driver name.

Example values:

  • com.mysql.jdbc.Driver (MySQL)
  • oracle.jdbc.driver.OracleDriver (Oracle)
  • com.microsoft.sqlserver.jdbc.SQLServerDriver (Microsoft SQL Server)

Only applicable to "Custom Datasource" option.

Custom JDBC URL

Database connection URL.

Example: jdbc:mysql://localhost:3306/jwdb

Only applicable to "Custom Datasource" option.

Custom JDBC Username

Database username.

Example: root

Only applicable to "Custom Datasource" option.

Custom JDBC Password

Specified database user's password.

Only applicable to "Custom Datasource" option.

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.
