Multi Column selection from a Sqlite table

[nagabathula]

hello thank you for help sir.. Until here i knew, i din know how to access only the column names which i have selected this can vary every time.. so i can't give a fixed column names..

SELECT column1, column2, columnX, columnY, columnZ FROM myDatabase LIMIT 2;

i i have a QVector in which has all the selected column names are there, which i need to pass in place of the column name in the query..
i don't know the syntax to use a QVector to give the column names instead of a fixed name.

SELECT channelnames.at(i) FROM myDatabase LIMIT 2; // QVectorString channelnames;

i don't know if this syntax is right.. what is the right way to do it sir.

thank you
