Allows a native SQL command to be executed directly against the datasource. In addition to being able to run any standard SQL command, use of this function allows a user to (potentially) utilize features specific to the datasource they are connected to that may not be available through ODBC. The ODBC driver will pass the specified command directly to the datasource.
+To get column amount and column names or other information about returned columns, pass {\it 'columns'} and {\it 'numcols'} parameters to the function also.
+
\wxheading{Parameters}
\docparam{pSqlStmt}{Pointer to the SQL statement to be executed.}
+\docparam{columns}{On success, this function will set this pointer to point to array of \helpref{wxDbColInf}{wxdbcolinf} objects, holding information about columns returned by the query. You need to call delete[] for the pointer you pass here after you don't use it anymore to prevent memory leak.}
+
+\docparam{numcols}{Reference to variable where amount of objects in {\it 'columns'}-parameter will be set.}
