Field Detail

connection

protected Connection connection

currentResultSet

protected ResultSet currentResultSet

currentUpdateCount

protected int currentUpdateCount

Constructor Detail

Statement

protected Statement(Connection connection)

Default constructor with JDBC connection.

Parameters:

connection - The JDBC connection

Method Detail

checkClosed

protected void checkClosed()
                    throws SQLException

Check if this statement is closed or not. If it is, we throw an exception.

Throws:

SQLException

getConnection

public Connection getConnection()
                         throws SQLException

Specified by:

getConnection in interface Statement

Throws:

SQLException

getUpdateCount

public int getUpdateCount()
                   throws SQLException

/!\ Like javadoc said, this method should be called one times. Bolt statement always return two results : ResulSet and updatecount. Because each time we retrieve a data we set it to the default value here we have two cases : - if there a resultset : we tell it by responding -1 - otherwise we give the updatecount and reset its value to default

Specified by:

getUpdateCount in interface Statement

Throws:

SQLException

getResultSet

public ResultSet getResultSet()
                       throws SQLException

Like javadoc said, this method should be called one times.

Specified by:

getResultSet in interface Statement

public void setMaxRows(int max)
                throws SQLException

Specified by:

setFetchSize

public void setFetchSize(int rows)
                  throws SQLException

Some tools call this method, so this just a workaround to make it work. If you set the fetch at Integer.MIN_VALUE, or if you put maxRows to -1, there is no exception. It's pretty much the same hack as the mysql connector.

Specified by:

setFetchSize in interface Statement

Throws:

SQLException

getMoreResults

Throws:

SQLException

getWarnings

public SQLWarning getWarnings()
                       throws SQLException

Some tool call this method, so for now just respond null. It will be possible to implement this an explain.

Specified by:

getWarnings in interface Statement

Throws:

SQLException
