Apex class question regarding queries

I am receiving the error: caused by: System.Exception: Too many SOQL queries: 101

 

My logic is below.  What I am trying to do:

 

1.  retrieve a list of all opportunities that match a certain criteria

2.  if that opportunity doesn't have any projects, update a custom field in the opportunity table (is_pipeline__c)

3.  if there is a project, if its project_stage__c = 'pipeline', update that is_pipeline__c filed

 

From my readings, I am hitting the 100 limit because for each iteration through my for loop, we are calling at least 1 soql statement and that will reach the limit fast.  Any thoughts on how I can get around this issue with my class code below?  Thanks 

 

     List<Opportunity> allOpps = [SELECT Id, Is_Pipeline__c FROM Opportunity WHERE billingtype__c <> null AND pldepartment__c <> null  AND Is_Pipeline__c = false AND stagename <> 'Closed Won']; //limit 60];

    

     for (Opportunity oppys : allOpps)

     {

    

     Integer existingProjects = [select count() from SFDC_Projects__c where opportunity__c = : oppys.Id];

    

     if (existingProjects < 1)

     {

     oppys.Is_Pipeline__c = true;

     update oppys;

     }

     else

     {

     SFDC_Projects__c project = [SELECT Project_Stage__c FROM SFDC_Projects__c WHERE opportunity__c = : oppys.Id];

    

     if (project.Project_Stage__c == 'Pipeline')

     {

     oppys.Is_Pipeline__c = true;

     update oppys;

     }

     }

Use SOQL query to retrieve opportunity records in bulk as follows -

for (List<Opportunity> opptys: [SELECT Id, Is_Pipeline__c FROM Opportunity WHERE billingtype__c <> null AND pldepartment__c <> null AND Is_Pipeline__c = false AND stagename <> 'Closed Won']) { // Here you can get existing project count in bulk thus avoiding a SOQL for each project. }

Also, you might want to store the oppty sobjects being updated in a list and do a bulk update at the end of for loop This makes your code complex, but you are guarded against hitting governer limits on # of SOQLs, # of DML statements, # of records returned etc.

 

Even better, if this is not being run as part of a user transaction, consider using batch API.

Thanks for the help in creating the  for list.  However, I am not familiar with how to complete the section you talked about in the commented section....retrieving the project count in bulk.  Could you clarify please?

 

Thanks

Depending on the relationship between Opportunity and Project, you could also try using a related query to pull it all in the data in one query. Something like this:

 

List <SFDC_Projects__c> oproj = new List <SFDC_Projects__c> ();

List <Opportunity> opptys = new List <Opportunity> ();

 

opptys = [Select Id, Is_Pipeline__c, (select Id, Project_Stage__c from SFDC_Projects__c) from Opportunity WHERE billingtype__c <> null AND pldepartment__c <> null AND Is_Pipeline__c = false AND stagename <> 'Closed Won'];

for (Opportunity o: opptys) {

oproj = o.SFDC_Projects__c; //You'll need to find out the relationship name for the relationship to SFDC_projects__c//

 

Now you have a list of related projects, so you can execute your logic by checking the size of o.Proj

if (oproj.size() <1) {

o.Is_Pipeline__c = true;

}

else

{

for (SFDC_Projects__c sp: oproj) {

if (sp.Project_Stage__c == 'Pipeline'){

o.Is_Pipeline__c = true;}

}

}

update opptys;

}

To get the records from SFDC_Project__C in bulk, use this SOQL

[SELECT opportunity__c, Project_Stage__c FROM SFDC_Projects__c WHERE opportunity__c in: opptys];
