Parameters:

statement - current statement

size - initial data size

fetchSize - resultet fetch size

selectPossible - is select command possible

Method Detail

addResultSet

public void addResultSet(MariaSelectResultSet result,
                         boolean moreResultAvailable)

Add a resultSet information.

Specified by:

addResultSet in interface ExecutionResult

Parameters:

result - resultset implementation

moreResultAvailable - is there additional packet

addStats

public void addStats(long affectedRows,
                     long insertId,
                     boolean moreResultAvailable)

Add execution statistics.

Specified by:

addStats in interface ExecutionResult

Parameters:

affectedRows - number of affected rows

insertId - primary key

moreResultAvailable - is there additional packet

getInsertIds

public long[] getInsertIds()

Get insert ids.

Specified by:

getInsertIds in interface ExecutionResult

Returns:

insert ids results

getAffectedRows

public int[] getAffectedRows()

Get update array.

Specified by:

getAffectedRows in interface MultiExecutionResult

Returns:

update array.

hasMoreThanOneAffectedRows

public boolean hasMoreThanOneAffectedRows()

Specified by:

hasMoreThanOneAffectedRows in interface ExecutionResult

getFirstAffectedRows

public int getFirstAffectedRows()

Specified by:

getFirstAffectedRows in interface ExecutionResult

Specified by:

getFirstAffectedRows in interface MultiExecutionResult

addStatsError

public void addStatsError()

updateResultsForRewrite

public void updateResultsForRewrite(int waitedSize,
                                    boolean hasException)

Set resultSet for rewrite queries. INSERT INTO XX VALUES (YYY) INSERT INTO XX VALUES (ZZZ) is rewritten INSERT INTO XX VALUES (YYY), (ZZZ) so modified row, will all be on the first row, or on a few rows : queries will split to have query size under the max_allowed_size, so data can be on multiple rows

Specified by:

updateResultsForRewrite in interface MultiExecutionResult

Parameters:

waitedSize - batchSize

hasException - has exception

updateResultsMultiple

public void updateResultsMultiple(int waitedSize,
                                  boolean hasException)

Set update resultSet right on multiple rewrite. INSERT XXXX INSERT XXXX is rewritten INSERT XXXX;INSERT XXXX So affected rows and insert Id are separate in as many okPacket.

Specified by:

updateResultsMultiple in interface MultiExecutionResult

Parameters:

waitedSize - batchSize

hasException - has exception
