I having a problem getting the ID of the entity company selected from the dropdownlist. The value passes correctly to the class, but the SOQL query is returning the ID of the Company.com-KY even if I select one of the other ones. I am preatty sure that the problem is because I am using this: WHERE Name LIKE \'%'+String.escapeSingleQuotes(l)+'%\' LIMIT 1';

My question is if there is another way to get the Id using for example 'Where name ='

I already tried this:

soql = 'SELECT Id FROM Entity_c WHERE Name='+String.escapeSingleQuotes(l)+''; soql = 'SELECT Id FROM Entity_c WHERE Name= \'%'+String.escapeSingleQuotes(l)+'%\' ';

Thank you!

Here is my VF page dropdown list

  <select id="list" size="1" onChange="doSearch();"  >
   <option value="-" selected="selected">Select Entity</option>
   <option value="Company" >Company</option>
   <option value="Company.com">Company.com</option>
   <option value="Company.com-KY">Company.com-KY</option>

Here is the class

 public PageReference runSearch() {    
 String entity = Apexpages.currentPage().getParameters().get('list');

 soql = 'SELECT Id FROM Entity__c WHERE Name like \'%'+String.escapeSingleQuotes(entity)+'%\' LIMIT 1';


return null;


here is query and how assign the entity id to a variable

  public void runQuery() {

try {
  entity = Database.query(soql);
  objectlist =String.valueOf(entity);
  msg = 'Entity selected successfully !'; 

} catch (Exception e) {
  ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.ERROR, 'Ooops!'));


  • Is there a particular reason you are using "Like"? If you made the query specific to a name, you would get back the ID you want. – joshbirk Apr 10 '14 at 18:54
  • But I don't know how to do that, i would like to use where Name = but I dont know how to built the where statement using \'%'+String.escapeSingleQuotes(l)+'%\' – Carlos Apr 10 '14 at 18:58

Shift your query to a specific Name instead of LIKE:

public PageReference runSearch() {    
     String entity = Apexpages.currentPage().getParameters().get('list');
     try {
         objectlist = [SELECT Id from Entity__c WHERE Name = :entity];
     } catch (DMLException e) {
         //handle e

     return null;

    Not the use of a bind variable here (:entity) instead of string manipulation to create the query - always the better plan. Use of a bind variable prevents SOQL injection (see salesforce.com/us/developer/docs/apexcode/Content/…), so you don't need to use String.escapeSingleQuotes(entity). – Jason Clark Apr 10 '14 at 19:26
  • Good point @JasonClark - removing the string call from the sample in the answer. And yes, avoid stringifying your own query call whenever possible. – joshbirk Apr 10 '14 at 20:10

Try to use built in apex components when you can. Use the <apex:selectList> and <apex:selectOption> to bind your data directly to your controller instead of passing it through page parameters. Doing it this way is safer and more efficient.
