We have issue with one of the apex class which stopping us from configuring a record through lightning component. When we debugged the issue we found this error in debug logs and could not identify what is the issue related to.

Class:

public with sharing class customLookUpController {

 @AuraEnabled
public static List <sObject> fetchLookUpValues(String searchKeyWord, String objectName, String queryFilterField, String fieldsToQuery) {  
    String searchKey = searchKeyWord + '%';
    fieldsToQuery = fieldsToQuery != '' ? ', '+fieldsToQuery : fieldsToQuery;
    String sQuery = 'SELECT id, Name'+fieldsToQuery+' FROM '+objectName+' WHERE Name LIKE \''+searchKey+'\' '+queryFilterField+' ORDER BY createdDate DESC LIMIT 5';
    
    List<sObject> returnList = new List<sObject>();
    for (sObject obj : Database.query(sQuery)) returnList.add(obj);
    return returnList;
}


@AuraEnabled
public static List <sObject> fetchLookUpValues(String searchKeyWord, String objectName, String queryFilterField) {  
    String searchKey = searchKeyWord + '%';
    String sQuery = 'SELECT id, Name FROM '+objectName+' WHERE Name LIKE \''+searchKey+'\' '+queryFilterField+' ORDER BY createdDate DESC LIMIT 5';
    
    List<sObject> returnList = new List<sObject>();
    for (sObject obj : Database.query(sQuery)) returnList.add(obj);
    return returnList;
}

@AuraEnabled
public static List <sObject> fetchLookUpValuesNew(String searchKeyWord, String objectName, String queryFilterField, String fields, String queryConditions) {  
    String searchKey = searchKeyWord + '%';
    String sQuery;
    //String allfields = '';
    if(queryConditions != null && queryConditions != ''){
        sQuery = 'SELECT '+fields+' FROM '+objectName+' WHERE '+queryFilterField+' LIKE \''+searchKey+'\' '+' AND '+ queryConditions +' ORDER BY createdDate DESC LIMIT 10';
        System.debug('sQuery--'+sQuery);
    }
    else{
        sQuery = 'SELECT '+fields+' FROM '+objectName+' WHERE '+queryFilterField+' LIKE \''+searchKey+'\' '+' ORDER BY createdDate DESC LIMIT 10';
        System.debug('sQuery--'+sQuery);
    }     
    List<sObject> returnList = new List<sObject>();
    for (sObject obj : Database.query(sQuery)) returnList.add(obj);
    return returnList;
}

}

  • Please debug searchKeyWord, objectName, queryFilterField and fieldsToQuery in the first fetchLookUpValues method where the error is happening.

  • Log the actual query string being executed. The problem will almost certainly become visible immediately.

  • @DavidReed I tried System.debug (sQuery); but the log did not provided me the query results.

  • Not the results, what is the actual query that you are trying to execute that results in the exception being thrown.

  • @DavidReed Here is the query i received "SELECT id, Name, Multi_Temperature__c, Undermount__c, CC_Parent__c FROM SG_ProductBook__c WHERE Name LIKE '%' AND CC_Enabled__c=true AND (id IN ) OR CC_Parent__c IN )) ORDER BY createdDate DESC LIMIT 5"

As stated in a comment, the actual query being executed is

SELECT id, Name, Multi_Temperature__c, Undermount__c, CC_Parent__c 
FROM SG_ProductBook__c 
WHERE Name LIKE '%' AND CC_Enabled__c=true AND (id IN ) OR CC_Parent__c IN )) 
ORDER BY createdDate DESC LIMIT 5

That immediately shows the problem:

(id IN ) OR CC_Parent__c IN )

One of the strings you are templating in to build a WHERE clause is not valid SOQL.
