How to generate user selection choice values using SQL

def applicationId = 1  // Get this value out of your cwd_application database or modify the sql below to get it dynamically
def ANY = '*'  // Special value to represent any user id (like in JIRA)


/**
 * Get colon separated list of users - userid:displayName - order by name
 */
def getUserChoice() {

    def sql = """
        select lower_user_name || ':' || quote_nullable(display_name) || ':\\\\'
            from cwd_user where
                (lower_user_name not like '%-admin%')
                and (lower_user_name not like 'automation%')
                and (directory_id in (select directory_id from cwd_app_dir_mapping where application_id = ${applicationId}))
            order by display_name
        """
    def userChoice = "${ANY}:Any:current_user_id:Current user:" + getChoice(sql, crowdDataSource) 
    return userChoice
}

/**
 * General function to run SQL for choice text
 */
def getChoice(final sql, final dataSource) {

    def choiceMacro = "{sql-query:datasource=${dataSource}|table=false} ${sql} {sql-query}"
    def choices = subRenderer.render(choiceMacro, context, renderMode)


    if (choices.contains('div class="error"')) {
        println "Error rendering macro: ${choiceMacro}"
        println "Error: ${choices}"
        return "ERROR"
    }
    return choices
}
