What error?
I can not see why THIS line should provoke any error; but be aware
that you are creating a vector of INVALID pointers. The return from
sqlite3_column_text is not valid after subsequent calls to any of
sqlite3_step/sqlite3_reset/sqlite3_finalize.
You need to make a copy of the string and store that, not the pointer
returned from sqlite3_column_text.
