Introduction

JDBC Datalist Database Binder gives you the flexibility of designing a datalist by using your own custom SQL queries and database connection.

JDBC Datalist Properties

Configure JDBC Datalist Binder

NameDescriptionScreens (Click to view)
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.


Test the connection parameters

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

SQL SELECT Query 
SQL Select query to populate the datalist.


Example
SELECT * FROM app_fd_myTable

If a column name contains a dot character " . ", do ensure it is encapsulated properly.

For example for MySQL, it should be encapsulated like this:

SELECT 'myAppName.myColumn' FROM app_fd_myTable;

Table & Column Naming

  • For database tables created by Joget Forms, Joget adds a "c_" in front of table column names (or "t_" if your column name starts with a number) and "app_fd_" in front of database table names.
  • If you use environment hash variables to store SQL query strings, use "?noescape" to escape SQL query strings in JDBC binders to prevent the "<>" "not equal" operator from being converted, i.e. disables XSS prevention checking. Read here for more information..
Primary Key 

Define the primary key column.

By default, it should be "id".

Optimize query for paging

When checked, the binder only fetches selected page's items rather than the returning the whole data set to optimize the performance for large dataset paging.

Only works for MySQL and Microsoft SQL Server 2012 onwards.
