Method Detail

checkClosedback to summary
pack-priv void checkClosed() throws SQLException

An internal check for closed statements.

Exceptions
SQLException:
when the connection is closed
closeback to summary
pack-priv void close() throws SQLException

Implementation in subclasses

Exceptions
SQLException:
on access error
closeOnCompletionback to summary
public void closeOnCompletion() throws SQLException

Specifies that this Statement will be closed when all its dependent result sets are closed. If execution of the Statement does not produce any result sets, this method has no effect.

Note

Multiple calls to closeOnCompletion do not toggle the effect on this Statement. However, a call to closeOnCompletion does effect both the subsequent execution of statements, and statements that currently have open, dependent, result sets.

Exceptions
SQLException:
if this method is called on a closed Statement
Since
JDK 1.7, HSQLDB 2.0.1
closeResultDataback to summary
pack-priv void closeResultData() throws SQLException

See comment for getMoreResults.

pack-priv ResultSet getGeneratedResultSet() throws SQLException
getMoreResultsback to summary
pack-priv boolean getMoreResults() throws SQLException
getMoreResultsback to summary
pack-priv boolean getMoreResults(int current) throws SQLException

Not yet correct for multiple ResultSets. Should keep track of all previous ResultSet objects to be able to close them

getResultSetback to summary
pack-priv ResultSet getResultSet() throws SQLException
getUpdateCountback to summary
pack-priv int getUpdateCount() throws SQLException
isCloseOnCompletionback to summary
public boolean isCloseOnCompletion() throws SQLException

Returns a value indicating whether this Statement will be closed when all its dependent result sets are closed.

Returns:boolean

true if the Statement will be closed when all of its dependent result sets are closed; false otherwise
