Database Connector in Mule | Update Data in MYSQL

Database Connector in Mule | Update Data in MYSQL

Here we are performing update operation in MySQL database.

Http Method : PUT

Below is the update flow where we used 'Byte Array to String' & 'JSON to Object' for converting incoming request from byte form to database object.

Here in HTTP Configuration rest of the settings are same as previous except path is set to : /updateinfo

In DB Connector, choose operation as Update and write parameterized query as shown below

save it by ctrl+s

We have used set payload component to display a user friendly message as : Data is updated successfully.

Finally, run the project and once it is deployed please select PUT method in postman and hit URL :


Output :

Data is updated successfully

Below is XML code for above flow :
