karen_panda SOQL - same province and city records
Hello,
I'm new to Force.com.
I have a custom object: percentage__c with the following custom fields:
Account
Province__c
City__c
Team__c
Allocation__c
I need to create an after insert, after update, after delete trigger to update the allocation__c field if there are more than one Team__c for the same Account, Province__c, and City__c.
Here are some sample data:
Account1 ON Toronto Team1 100
Account2 ON Niagara Falls Team1 100
when Account3 comes in,
Account3 ON Toronto Team2 100
the trigger should update both Account1 and Account3 to 50, the total should always be 100.
Account1 ON Toronto Team1 50
Account3 ON Toronto Team2 50
I need help on how to get the same Province__c and City__c from the existing records based on triggers.new in a set of Id.
Any help is appreciated.
Regards,
Karen
You can use map I guess:
Map<String,String> strCityMap = new Map<String,String>();
for(String str1:pCity)
{
for(String str2:pProvince)
{
strCityMap.put(str1,str2);
}
}
All Answers
Yes, each record gets allocation =25 if there are 4 records for Account1 ON Toronto with different Teams.
Thanks,

Hello,
I tried to start with the following code:
//get a set of the unique province and city
Set<String> pCity = new Set<String>();
Set<String> pProvince = new Set<String>();
for (percentage__c p: Trigger.new)
{
pCity.add(p.City__c);
pProvince.add(p.Province__c);
}
//get a set of cities which have more than one Team shared
Set<String> Cities = new Set<String>();
for (percentage__c existingCities : [select Id, city__c from percentage__c group by city__c having count(city__c ) > 1]);
{
Cities.add(existingCities.city__c);
}
then plan to compare whether set pCity is inside set Cities.
I'm getting stuck for going further.
Any help or even just a high-level guidance is appreciated.

Hello,
I noticed my SOQL [select Id, city__c from percentage__c group by city__c having count(city__c ) > 1] would fail if there are 2 provines with the same city name.
I would like to simplify my question to how can I get a list of province, city which have more than one record in the database.
For example:
Account1 ON Toronto Team1
Account1 ON Toronto Team2
Account2 BC Toronto Team3
Account2 BC Toronto Team4
Account3 ON Niagara Falls Team5
I want the query return:
ON Toronto
BC Toronto
Any help is appreciated.
