If TQuery is used to iterate through your records in the dbf table from
the beginning to the end, then set Unidirectional to true.
Use a TIB_DSQL for the insert process, by using a parametrized INSERT
INTO statement, prepare the statement outside your loop and set the
parameter values in your loop and execute the INSERT INTO statement.
Do regular hard commits on TIB_DSQL.
