MySQL Connector (Single Row)

This template demonstrates how to integrate a MySQL Database as a live data source within a Decision Flow. It specifically shows how to use the DB Single Row node, how to pass variables to the SQL query, and how to fetch data from the database and propagate it into the flow’s output.

MySQL Connector (Single Row) 1
The primary objective of this flow is to show how to retrieve information from an external database using a single string input and return a corresponding result. 
It connects to a user-defined MySQL infrastructure and executes a query against a standard single-row table.

Solution Components
The workflow is composed of several specialized nodes that handle the data lifecycle from input to final assignment:
  • DB Single Row Node (mysql_single_row):
    • Function: Connects to the database using the connector alias conn-mysql-templates.
    • Logic: Executes the SQL statement.

    • Constraint: This node is designed to return exactly one row. For multiple rows, use a standard database node instead.

  • Data Manipulation Node (assign):
    • Function: Extracts the result from the database node.
    • Logic: Maps the value found at mysql_single_row.row to the final output.

How to Use This Rule
To successfully utilize this template, the following steps must be completed:
  1. Prerequisite: Ensure your MySQL DB instance is accessible from the DecisionRules backend (Cloud or On-Premise).
  2. Setup: Create a Database Connector in the Space settings with the specific alias conn-mysql-templates.
  3. More details could be found in the main flow description - in the Flow Designer, select in the Sidebar the Rule Settings  and scroll down to Description
