Description
The
result_names()
predefines variables to be used in a result set to follow. The variables must
be previously declared, from which the column data types are ascertained.
This assigns the meta data but does not send any results. The
result()
function sends its parameters as a single row
of results. These parameters should be compatible with those in the previous
result_names()
. The end_results()
function can be used to separate multiple result sets. The
result_names()
can then be used to alter
the structure of the next result set.
The result_names()
call can be omitted if
the application already knows what columns and their types are to be returned.
Parameters
var_1, ..., var_n
The column variables previously declared or otherwise.
