Introduction

• The Database connector allows you to connect with almost any Java Database Connectivity (JDBC) relational database with a single interface for the most common database engines

• Run SQL operations on your database, including Select, Insert, Update, Delete, and even Stored Procedures

Introduction

• The Database connector lets you perform predefined queries or dynamically constructed queries

• Perform multiple SQL requests in a single bulk update

• Rerform Data Definition Language (DDL) requests, that alter the data structure rather than the data itself

Supported Operations

• Select• Insert• Update • Delete• Stored Procedure• Bulk Execute• DDL operations such as CREATE, ALTER

Database Connector Global Element Configuration

1. Click a database connector building block that you have included in your flow


2. Select the type of database global element to configure


3. Choose a type of database global element to set up


4. For MySQL database connection, you must fill out these fields in the Global Element Properties screen:• Host• Port• User• Password• Database


5. Specify the database engine driver on the Global Element Properties window


6. At this point, the database connection should be confirmed via Test Connection button. Click OK when confirmed.

7. Back in the properties window ensure a valid operation and query have been specified for the database connector building block(s) before running your app
