Constructor & Destructor Documentation

virtual odbc::Statement::~Statement ( ) [virtual]

Destructor.
Destroys/closes this statement as well as all created resultsets.

Member Function Documentation

virtual bool odbc::Statement::execute ( const std::string & sql ) [virtual]

Execute a given SQL statement.
The statement can return multiple results. To get to the next result after processing the first one, getMoreResults() should be called.
Parameters:

sql The string to execute

Returns:
true if a resultset is available

virtual ResultSet* odbc::Statement::executeQuery ( const std::string & sql ) [virtual]

Execute an SQL statement, expected to return a resultset.

Parameters:

sql The string to execute

Returns:
A ResultSet object.

virtual int odbc::Statement::executeUpdate ( const std::string & sql ) [virtual]

Execute an SQL statement, expected to return an update count.

Returns:
The number of affected rows

bool odbc::Statement::getEscapeProcessing ( )

Gets the current escape processing setting.

Returns:
true if escape processing is on, false otherwise

bool odbc::Statement::getMoreResults ( )

Check if there are more results available on this statment.

Returns:
True if this statement has more results to offer.

int odbc::Statement::getUpdateCount ( )

Fetch the current result as an update count.

Returns:
the current result's update count (affected rows), or -1 if the result is a ResultSet or if there are no more results.

void odbc::Statement::setEscapeProcessing ( bool on )

Sets escape processing on or off.
For PreparedStatements, the command has been parsed on creation, so this setting won't really have any effect.
