Results

public Results(int autoIncrement)

Single Text query.

Parameters:

autoIncrement - connection auto increment

Results

public Results(MariaDbStatement statement,
               int fetchSize,
               boolean batch,
               int expectedSize,
               boolean binaryFormat,
               int resultSetScrollType,
               int autoIncrement)

Default constructor.

Parameters:

statement - current statement

fetchSize - fetch size

batch - select result possible

expectedSize - expected size

binaryFormat - use binary protocol

resultSetScrollType - one of the following ResultSet constants: ResultSet.TYPE_FORWARD_ONLY, ResultSet.TYPE_SCROLL_INSENSITIVE, or ResultSet.TYPE_SCROLL_SENSITIVE

autoIncrement - connection auto increment

Method Detail

addStats

public void addStats(int updateCount,
                     long insertId,
                     boolean moreResultAvailable)

Add execution statistics.

Parameters:

updateCount - number of updated rows

insertId - primary key

moreResultAvailable - is there additional packet

addStatsError

public void addStatsError(boolean moreResultAvailable)

Indicate that result is an Error, to set appropriate results.

Parameters:

moreResultAvailable - indicate if other results (ResultSet or updateCount) are available.

getCurrentStatNumber

public int getCurrentStatNumber()

addResultSet

public void addResultSet(MariaSelectResultSet resultSet,
                         boolean moreResultAvailable)

Add resultSet to results.

Parameters:

resultSet - new resultSet.

moreResultAvailable - indicate if other results (ResultSet or updateCount) are available.

getCmdInformation

public CmdInformation getCmdInformation()

commandEnd

public void commandEnd()

Indicate that command / batch is finished, so set current resultSet if needed.

getResultSet

public MariaSelectResultSet getResultSet()

getCallableResultSet

public MariaSelectResultSet getCallableResultSet()

loadFully

public void loadFully(boolean skip,
                      Protocol protocol)
               throws SQLException,
                      QueryException

Load fully current results. Lock must be set before using this method

Parameters:

skip - must result be available afterwhile

protocol - current protocol

Throws:

SQLException - if any connection error occur

QueryException - if any connection error occur

getMoreResults

public boolean getMoreResults(int current,
                              Protocol protocol)
                       throws SQLException

Position to next resultSet.

Parameters:

current - one of the following Statement constants indicating what should happen to current ResultSet objects obtained using the method getResultSet: Statement.CLOSE_CURRENT_RESULT, Statement.KEEP_CURRENT_RESULT, or Statement.CLOSE_ALL_RESULTS

protocol - current protocol

Returns:

true if other resultSet exists.

Throws:

SQLException - if any connection error occur.

getFetchSize

public int getFetchSize()

getStatement

public MariaDbStatement getStatement()

isBatch

public boolean isBatch()

setCmdInformation

protected void setCmdInformation(CmdInformation cmdInformation)

getExpectedSize

public int getExpectedSize()

isBinaryFormat

public boolean isBinaryFormat()

removeFetchSize

public void removeFetchSize()

getResultSetScrollType

public int getResultSetScrollType()

getGeneratedKeys

public ResultSet getGeneratedKeys(Protocol protocol)

Send a resultSet that contain auto generated keys. 2 differences :

1. Batch will list all insert ids.
2. in case of multi-query is set, resultSet will be per query.

example "INSERT INTO myTable values ('a'),('b');INSERT INTO myTable values ('c'),('d'),('e')" will have a resultSet of 2 values, and when Statement.getMoreResults() will be called, a Statement.getGeneratedKeys will return a resultset with 3 ids.

Parameters:

protocol - current protocol

Returns:

a ResultSet containing generated ids.
