Constructor Detail

StoredProcedureQuery

public StoredProcedureQuery(org.datanucleus.store.StoreManager storeMgr,
                            org.datanucleus.store.ExecutionContext ec,
                            StoredProcedureQuery query)

Parameters:

storeMgr - StoreManager

ec - Execution Context

query - Existing query to base this one

StoredProcedureQuery

public StoredProcedureQuery(org.datanucleus.store.StoreManager storeMgr,
                            org.datanucleus.store.ExecutionContext ec)

Parameters:

storeMgr - StoreManager

ec - ExecutionContext

StoredProcedureQuery

public StoredProcedureQuery(org.datanucleus.store.StoreManager storeMgr,
                            org.datanucleus.store.ExecutionContext ec,
                            String procName)

Constructs a new query instance for the specified stored procedure name.

Parameters:

storeMgr - StoreManager for this query

ec - execution context

procName - Name of the stored procedure

Method Detail

compileInternal

protected void compileInternal(Map parameterValues)

Specified by:

compileInternal in class org.datanucleus.store.query.Query

processesRangeInDatastoreQuery

public boolean processesRangeInDatastoreQuery()

Overrides:

processesRangeInDatastoreQuery in class org.datanucleus.store.query.Query

executeQuery

protected Object executeQuery(Map parameters)

Method to execute the actual query. Overrides the version in Query since that will handle result set processing and assumes that this is a normal query, which it isn't.

Overrides:

executeQuery in class org.datanucleus.store.query.Query

Parameters:

parameters - Map of parameter values keyed by parameter name

Returns:

Boolean, which is true if there is a result set, and false if an update count.

performExecute

protected Object performExecute(Map parameters)

Specified by:

performExecute in class org.datanucleus.store.query.Query

hasMoreResults

public boolean hasMoreResults()

Specified by:

hasMoreResults in class org.datanucleus.store.query.AbstractStoredProcedureQuery

getUpdateCount

public int getUpdateCount()

Specified by:

getUpdateCount in class org.datanucleus.store.query.AbstractStoredProcedureQuery

getNextResults

public Object getNextResults()

Specified by:

getNextResults in class org.datanucleus.store.query.AbstractStoredProcedureQuery
