getCount

public long getCount(String entityName)

Description copied from interface: OfBizDelegator

Runs a COUNT * query over the given entity.

Ensure that there is a view-entity defined in entitymodel.xml and entitygroup.xml for the entity you are calling this method with, and that the view-entity is named correctly! The view-entity must be named the name of the normal entity with "Count" appended. For example, for the "Issue" entity, the view-entity must be called "IssueCount". Otherwise an exception will be thrown.

For JIRA core developers, see EntityEngine's Select factory for a more flexible alternative, including the ability to terminate queries with .count() instead of .asList() to accomplish a count without creating a special view entity for that purpose. For add-on developers, this can only be done directly through the lower level DelegatorInterface at this time.

Specified by:

getCount in interface OfBizDelegator

Parameters:

entityName - entity name

Returns:

count

getCountByAnd

public long getCountByAnd(String entityName,
                 Map<String,?> fields)

Description copied from interface: OfBizDelegator

Runs a COUNT * query over the given entity with some WHERE conditions.

In addition to the restrictions given for OfBizDelegator.getCount(String), the view-entity will need to define any columns that you wish to use in the where clause.

Specified by:

getCountByAnd in interface OfBizDelegator

Parameters:

entityName - entity name

fields - The fields of the named entity to query by with their corresponding values

Returns:

count
