SCOPE clasue in SOQL

The new USING SCOPE clause for SOQL queries lets you limit results by filterScope.

SELECT column_name FROM table_name USING SCOPE filterScope_value

filterScope_value can take one of the following enumeration values:

  • Everything – All records, for example All Opportunities.
  • Mine – Records owned by the user running the list view, for example My Opportunities.
  • Queue – Records assigned to a queue.
  • Delegated – Records delegated to another user for action: for example, a delegated task. This option is available in API version 17.0 and later.
  • MyTerritory – Records in the territory of the user seeing the list view. This option is available if territory management is enabled for your organization. This option is available in API version 17.0 and later.
  • MyTeamTerritory – Records in the territory of the team of the user seeing the list view. This option is available if territory management is enabled for your organization. This option is available in API version 17.0 and later.
  • Team – Records assigned to a team. This option is available in API version 17.0 and later.

Here is an example:

SELECT Name FROM Account USING SCOPE Mine

Difference between SOQL and SOSL

SOQL(Salesforce Object Query Language):

  • SOQL is a Salesforce Object Query Language, retrieves the records from the database by using SELECT keyword.
  • SOQL is used if we know in which object the data is present.
  • In SOQL we can query data from single object and as well as multiple objects that are related to each other.
  • We can query on all fields of any datatype.
  • We can use SOQL in Triggers and classes.
  • We can perform DML operation on query results.

SOSL(Salesforce Object Search Language):

  • SOSL is a Salesforce Object Search Language, retrieves the records from the database by using the FIND keyword.
  • SOSL is used if we don’t know in which object the data is present.
  • We can retrieve multiple objects and field values efficiently when the objects may or may not be related to each other.
  • We can query only on fields whose data type is text, phone and Email.
  • We can use in classes but not in Triggers.
  • We cannot perform DML operation on search result.
