Detailed Description

representation of a stored query.

Through this object we access the fields and parameters of the query, if any.

WARNING: this is unfinished: will gain query type (select, insert, update, delete) and parameter parsing and a lot of other stuff !!!

Member Function Documentation

QString SQL ( )

return the SQL code associated to the query. if the query is in design mode, it will build with the actual tables, fields and conditions

void addCondition ( const QString & condition )

add a condition (where clause, but without 'where') to the query.

void addField ( const QString & table, const QString & name )

append a new field to the output list of the query it works only in design mode.

void addTable ( const QString & name )

add a table to the existing output list of tables.

void buildSQL ( ) [protected, virtual]

this function will create the SQL string to pass to the DBMS engine. It can be overridden by special types of queries ?? dunno if it will help

bool isDesign ( )

returns true if the query is in design mode.

RecordsetPtr openRecordset ( )

creates a recordset based on this query.
