Bind Variables in a SOQL Query - getContactIDWithBinds
public class QueryContact {
public static Id getContactID(String lastName, String title) {
try {
Contact myContact = [SELECT Id FROM Contact WHERE LastName = :lastName AND Title = :title LIMIT 1];
return myContact.Id;
} catch (Exception ex) {
return null;
}
}
public static Id getContactIDWithBinds(Map<String, Object> bindVars) {
// do not modify any code above this line
// implement the logic that will use bindVars to retrieve the contact's ID
String queryString = 'SELECT Id FROM Contact WHERE LastName = :lastName AND Title = :title LIMIT 1';
try {
// Ensure that the bind variables contain the necessary keys
if (bindVars.containsKey('lastName') && bindVars.containsKey('title')) {
List<Contact> contacts = (List<Contact>)Database.queryWithBinds(queryString, bindVars, AccessLevel.USER_MODE);
if (contacts != null && !contacts.isEmpty()) {
// Assuming you want the first contact's ID if there are matches
return contacts[0].Id;
} else {
// Handle the case when no matching contacts are found
return null;
}
} else {
// Handle the case when required bind variables are not provided
return null;
}
} catch (Exception ex) {
// Handle exceptions, e.g., if the query fails
