Please help me how to get value for split values "valueArray[1]" in below query.

I am trying to fetch the records, but i found issue in writing dynamic query. Please let me know if I am missing syntax in belowsoql query.

List<String> valueArray = new List<String>();
    for(String strValues : listOfValues) {
     valueArray = strValues.split('-');
     Integer intValue = Integer.ValueOf(valueArray[1]);
    for(sObject sObj : Database.query('SELECT Id FROM ' + valueArray[0] + ' WHERE CreatedDate < Last_N_Days:intValue ')) {
  • Welcome to SFSE! valueArray is a String in this example, you cannot access the index of a String. What does listOfValues look like, something like {'Account-20', 'Contact-10'}` i.e look for Accounts created in last 20 days, look for Contacts created in last 10 days?

Bind variables in Dynamic Apex do not support complex expressions (e.g. accessing an array), so you just need to use normal string concatenation:

for(sObject sObj : Database.query('SELECT Id FROM ' + 
    String.escapeSingleQuote(valueArray[0]) + 
    ' WHERE CreatedDate < Last_N_Days:' +
    String.escapeSingleQuote(valueArray[1]))) {

    SOQL injection attack prevention encoding should be added here...

  • @PhilW Fair enough. I try not to assume too much about where the input comes from, but as a general best practice, one should definitely escape quotes.

  • in valueArray, there are multiple objects and it's related number but I am getting only one sobject from valueArray[0], after that execution is being stopped. I have checked in debug logs. Dec 21, 2021 at 18:47
  • @sfdcfox if the OP is looking to query many objects (unknown from List), how would we tackle or improve this from platform limit perspective?

    @TSmith I don't want to assume too much, the query looks like it's incorrect anyways (they probably meant = instead of <). If that's true, Database.getUpdated returns records created and updated within a time window, for free (no governor limits are used aside from CPU/heap). If they need to query hundreds of objects, then context will matter. Might need to call it from a loop client-side, or batchable, etc. It's too vague to give a specific solution.
