Collection the data metrics where there are unique keys

i have changed the code as mentioned below

import groovy.sql.Sql

// Get basic info to connect
def hostname = hostProps.get("system.hostname")
def user = hostProps.get("sybase.user")
def pass = hostProps.get("sybase.pass")
def port = 21000

// Construct an SQL instance with a URL and a driver
def url = "jdbc:sybase:Tds:$hostname:$port"
def driver = "com.sybase.jdbc4.jdbc.SybDriver"
def sql = Sql.newInstance(url, user, pass, driver)
def conn = sql.getConnection()

try {
    def stmt = conn.createStatement()

    // Retrieve database names and IDs
    def dbRs = stmt.executeQuery("select name, dbid from sysdatabases")

    while (dbRs.next()) {
        def dbName = dbRs.getString("name")
        def dbId = dbRs.getInt("dbid")

        // Retrieve segment information for each database
        def segmentRs = stmt.executeQuery("select name from '${dbName}'..syssegments where dbid = ${dbId}")

        while (segmentRs.next()) {
            def segmentName = segmentRs.getString("name")

            // Process segment information and create instance
            def instanceName = "${dbName}_${segmentName}_segment"
            def instanceConfig = [segment: segmentName]
            createInstance(instanceName, instanceConfig)
        }

        segmentRs.close()
    }

    dbRs.close()
    stmt.close()
} catch (e) {
    // Handle SQL exception
    e.printStackTrace()
} finally {
    if (conn != null) {
        conn.close()
    }
}

def createInstance(name, config) {
    def description = config.description
    def prop1 = config.prop1
    def prop2 = config.prop2

    println("${name}##${name}##${description}####prop1name=${prop1}&prop2name=${prop2}")
}

i am getting the following output
