Getting error too many soql

Hi,

 I am getting error too many SOQL queries.

list<lead> myLeadList=[select id,name,Ad_key__c,Advertising_Key__c from lead where Ad_key__c =null];
for(lead l:myLeadList){
 list<Lead_Vendors__c> le=[select id,Ad_key__c from Lead_Vendors__c where Ad_key__c=:l.Advertising_Key__c];
    if(le!=null && le.size()>0){
    l.Ad_key__c=le[0].id;
    update l;    
    }
    
}

Hi Ashu,

Please use the below code to avoid too many SOQL errors.
  
list<lead> myLeadList=[select id,name,Ad_key__c,Advertising_Key__c from lead where Ad_key__c =null];
system.debug('myLeadList:::'+myLeadList);
list<Lead_Vendors__c> le=[select id,Ad_Key__c from Lead_Vendors__c ];
system.debug('le:::'+le);
list<Lead> newLead = new List<Lead>();
if(le.size()>0){
    for(lead l:myLeadList){
        system.debug('in for loop');
        for(Lead_Vendors__c lv :le){
            if(lv.Ad_key__c == l.Advertising_Key__c ){
                Lead leObj = new Lead(); 
                leObj.Ad_Key__c=le[0].id;
                leObj.Id = l.id;
                newLead.add(leObj);
            }   
        }
    }
  system.debug('newLead:::'+newLead);
  update newLead;   
}

Please read the below blog for the following point:

1. Avoid SOQL Queries or DML Statements inside ‘FOR Loops’ :
As we know how ‘For’ loop handles multiple records in bulk. When SOQL queries and DML statements are placed inside a ‘for loop’,  these are invoked for every iteration of the loop. Because of this, governor limits will be reached, so it would be best to avoid these scenarios whenever possible.

I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.
