Utilizing Mirth Connect to insert XML data into a MySQL database using JavaScript

I am completely new to working with Mirth, JavaScript, and MySQL. I have successfully set up a channel in Mirth to read a text file and convert it to XML. Everything is functioning properly so far. I also attempted to send the XML data to a MySQL database using the Database Writer in another channel.

Here is an example of the JavaScript code:

var dbConn = DatabaseConnectionFactory.createDatabaseConnection('com.mysql.jdbc.Driver','jdbc:mysql://192.168.1.4:3306/mirth','root','');
var result = dbConn.executeUpdate('INSERT INTO jon (xml) values ('1234')');
dbConn.close();

The above code successfully inserts a record into the 'jon' table with the value of '1234'. However, my main question is how can I send the XML that I have read through the channel reader source to the database? I have tried replacing '1234' with ('+messageObject.getEncodedData()+), rawdata, or transformeddata, but none of these options are working. Instead, I am encountering the following error:

ERROR (org.mule.impl.DefaultComponentExceptionStrategy:95) .... Wrapped com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '<?xml version="1.0" encoding="UTF-8"?><delimited><row><column1>1234</column1><co' at line 1 (1cf6717f-4818-4b18-acb2-3b93079f2e95#7) .....

My goal is to store the entire XML in one field without any parsing necessary at this stage. Thank you for your understanding. Best regards, janmohamamdi

Answer №1

The issue you're encountering appears to be a simple syntax error. Take a step back from Mirth for a moment. Typically, when inserting values into a character field in a database, you must enclose the value within single quotes.

INSERT INTO jon (xml) values ('1234') //ensure '1234' is enclosed in single quotes

When constructing a query in JavaScript within Mirth, you are essentially creating the same type of query used in MySQL, but programmatically generating it as a string. Essentially, you are crafting the following string and instructing JavaScript to run it:

"INSERT INTO jon (xml) values ('1234')" //single quotes around 1234

This implies that if you have an XML variable mapped, you need to place single quotes around it within the query string so that your database understands the value being inserted. The error message you're receiving likely indicates this issue. If you share the specific code you're using for the insertion, I can review it for you.

var xmlVar = $('XmlVar');  // assign value to a variable
var query = "INSERT INTO testMRN (sendingfacility) VALUES ('" + xmlVar + "')";  // ensure variable is enclosed in quotes 
var update= dbConn.executeUpdate(query);
