MySQL prepared statement.

Member Function Documentation

affectedRowCount()

virtual int Wt::Dbo::backend::MySQLStatement::affectedRowCount ( )

virtual

Returns the affected number of rows.

This is only useful for an SQL update or delete statement.

Implements Wt::Dbo::SqlStatement.

getResult() [1/9]

virtual bool Wt::Dbo::backend::MySQLStatement::getResult ( int  column, std::string *  value, int  size  )

virtual

Fetches a result value.

Returns true when the value was not null. The size is the expected size of sql string type and can be used to dimension buffers but the return string may be bigger.

Implements Wt::Dbo::SqlStatement.

getResult() [2/9]

virtual bool Wt::Dbo::backend::MySQLStatement::getResult ( int  column, short *  value  )

virtual

Fetches a result value.

Returns true when the value was not null.

Implements Wt::Dbo::SqlStatement.

getResult() [3/9]

virtual bool Wt::Dbo::backend::MySQLStatement::getResult ( int  column, int *  value  )

virtual

Fetches a result value.

Returns true when the value was not null.

Implements Wt::Dbo::SqlStatement.

getResult() [4/9]

virtual bool Wt::Dbo::backend::MySQLStatement::getResult ( int  column, long long *  value  )

virtual

Fetches a result value.

Returns true when the value was not null.

Implements Wt::Dbo::SqlStatement.

getResult() [5/9]

virtual bool Wt::Dbo::backend::MySQLStatement::getResult ( int  column, float *  value  )

virtual

Fetches a result value.

Returns true when the value was not null.

Implements Wt::Dbo::SqlStatement.

getResult() [6/9]

virtual bool Wt::Dbo::backend::MySQLStatement::getResult ( int  column, double *  value  )

virtual

Fetches a result value.

Returns true when the value was not null.

Implements Wt::Dbo::SqlStatement.

getResult() [7/9]

virtual bool Wt::Dbo::backend::MySQLStatement::getResult ( int  column, boost::posix_time::ptime *  value, SqlDateTimeType  type  )

virtual

Fetches a result value.

Returns true when the value was not null.

Implements Wt::Dbo::SqlStatement.

getResult() [8/9]

virtual bool Wt::Dbo::backend::MySQLStatement::getResult ( int  column, boost::posix_time::time_duration *  value  )

virtual

Fetches a result value.

Returns true when the value was not null.

Implements Wt::Dbo::SqlStatement.

getResult() [9/9]

virtual bool Wt::Dbo::backend::MySQLStatement::getResult ( int  column, std::vector< unsigned char > *  value, int  size  )

virtual

Fetches a result value.

Returns true when the value was not null.

Implements Wt::Dbo::SqlStatement.

nextRow()

virtual bool Wt::Dbo::backend::MySQLStatement::nextRow ( )

virtual

Fetches the next result row.

Returns true if there was one more row to be fetched.

Implements Wt::Dbo::SqlStatement.
