Method Detail

executeOnSpace

public ResponsePacket executeOnSpace(ISpaceProxy space,
                                     Transaction txn)
                              throws SQLException

Description copied from interface: Query

Will execute this query on the space and return a ResponsePacket

Throws:

SQLException

setUpdatedValues

public void setUpdatedValues(List<LiteralNode> values)

isByUid

public boolean isByUid()

Returns:

Returns the byUid.

setByUid

public void setByUid(boolean byUid)

Parameters:

byUid - The byUid to set.

clone

public Object clone()

Specified by:

clone in class AbstractDMLQuery

addUpdateColumn

public void addUpdateColumn(UpdateColumn updateColumn)

Adds a column name to the update columns list of the update query.

getUpdatedColumns

public List<UpdateColumn> getUpdatedColumns()

Gets the update columns list of the update query.

setSelfIncrementedUpdateColumn

public void setSelfIncrementedUpdateColumn(boolean selfIncrementedUpdateColumn)

Sets whether the query contains an update column which is self incremented.

isForceUnderTransaction

public boolean isForceUnderTransaction()

Gets whether this query is forced to be executed under transaction. If the query contains a column which is self incremented a TXN should be created for emulating compare & set.

Specified by:

isForceUnderTransaction in interface Query

Overrides:

isForceUnderTransaction in class AbstractDMLQuery

executePreparedValuesBatch

public BatchResponsePacket executePreparedValuesBatch(ISpaceProxy space,
                                                      Transaction transaction,
                                                      GPreparedStatement.PreparedValuesCollection preparedValuesCollection)

Description copied from class: AbstractDMLQuery

Executes a query with batched prepared values. This is the default implementation - NOT optimized.

Overrides:

executePreparedValuesBatch in class AbstractDMLQuery

Returns:

BatchResponsePacket

Throws:

SQLException
