You can use a HAVING clause with a GROUP BY clause to filter the results returned by aggregate functions, such as SUM(). SELECT CampaignId, AVG(Amount)FROM Opportunity GROUP BY CampaignId SELECT LeadSource, COUNT(Name) FROM Lead GROUP BY LeadSource WHERE IsClosed = false AND Probability > 60Īggregate functions become a more powerful tool to generate reports when you use them with a GROUP BY clause. For example: SELECT SUM(Amount) FROM Opportunity Returns the total sum of a numeric field. For example: SELECT Name, MAX(BudgetedCost) FROM Campaign GROUP BY Name

The function uses the sort order of the picklist values instead of alphabetical order. If you use the MIN() or MAX() functions on a picklist field, For example: SELECT MIN(CreatedDate), FirstName, LastNameįROM Contact GROUP BY FirstName, LastName To query for all the distinct values, including null, for an object, see GROUP BY. Note: COUNT_DISTINCT( fieldName) in SOQL is equivalent toĬOUNT(DISTINCT fieldName) in SQL. For example: SELECT COUNT_DISTINCT(Company) FROM Lead Returns the number of distinct non-null field values matching the query criteria. If you are using a GROUP BY clause, use COUNT( fieldName) instead of COUNT(). The COUNT( fieldName) syntax is available in API version 18.0 and later. Note: COUNT(Id) in SOQL is equivalent to COUNT(*) in SQL. For example using COUNT(): SELECT COUNT() FROM Account WHERE Nameįor example using COUNT( fieldName): SELECT COUNT(Id) FROM Account WHERE Name LIKE 'a%' Returns the number of rows matching the query criteria. For example: SELECT CampaignId, AVG(Amount) FROM Opportunity Returns the average value of a numeric field. This table lists all the aggregate functions supported by SOQL. SELECT CampaignId, AVG(Amount)FROM Opportunity GROUP BY CampaignId However, these functions become a more powerful tool to generate reports when you use them with a GROUP BY clause.įor example, you could find the average Amount for all your opportunities by campaign. You can use these functions without using a GROUP BY clause.įor example, you could use the AVG() aggregate function to find the average Amount for all your opportunities.
