    I created two code templates Library as follows.
    1. DB Library
    2. HL7 ADT V25 Library

    1. DB Library - Using for below data base operations.
    1.1 getDBConnnection - create connection object
    1.2 executeSelect - executing select query
    1.2 executeInsertOrUpdate - Performing insert update operations.

    2. HL7 ADT V25 Library - For ADT segments creation (set and get method).
    2.1 setPID - Select records from database and make object for constructing PID segment..
    2.2 getPID - Constructing PID segment.

    All the methods provided in the attached file.

    The transformation script channel is provided below.
    var dBConn = getDBConnnection($('dBProfile')); -- getting connection.
    //script for setup object
    var inPutPID = setPID(dBConn, hL7ADT.inPutPV1.mr_no, triggerEventID);
    //getting hl7 PID segment
    var pID = <PID/>;
    var inputDataPID = $('hL7ADT').inPutPID
    pID = getPID(inputDataPID);

    Mirth version using is

    I can access code template "executeSelect" (created in Library - DB Library)
    from setPID(Library - HL7 ADT V25 Library).

    Its working in my development environment.

    My aim is for all the ADT's i am creating separate channels and i need to reuse all the set , get and db code templates for constructing all ADT messages.

    My questions are below. Please help me.
    1. The process I am following is correct?
    2. Is it possible to call one code template created in Library 1 from another code template created in another code library. Is working in my dev setup. Please help me on this.
    3. Writing js for constructing hl7 message is right?

    Firstly, I'd suggest you rename your post for the kind of help you are seeking.

    Secondly, I would break out your questions to unique threads.

    As for "is the process you are following correct?" question - there are often many ways to do things in Mirth so you need to be mindful of how scalable your work is. For example, many folks have a set of variables in the configuration map (Setting...Configuration Map) for the storage of DB connect parameters (the v3_ variables below). Then use a shared code template for DB calls like:

    function executeSharedDBStatement(statement, isQuery, paramList)
    	var result;
    		var dbConn = globalMap.get("dbConn");
    		if (dbConn == null || dbConn.getConnection().isClosed())
    			dbConn = DatabaseConnectionFactory.createDatabaseConnection(configurationMap.get('v3_pg_driver'),configurationMap.get('v3_pg_url'),configurationMap.get('v3_pg_username'),configurationMap.get('v3_pg_password'));
    			globalMap.put("dbConn", dbConn);
    		if (paramList == undefined)
    			paramList = new;
    		if (isQuery)
    			result = dbConn.executeCachedQuery(statement, paramList);
    			result = dbConn.executeUpdate(statement, paramList);
    	catch (e)
    		return result;
    You can then call the function like

    var expression = "<your SQL code that does a select>"
    var result = executeSharedDBStatement(expression, true);
    var expression = "<your SQL code that does an insert that does not expect any outputt>"
    var result = executeSharedDBStatement(expression, false);
