The BDE sort function DbiSortTable sorts an opened or closed table, either into itself or into a destination table. There are options to remove duplicates, to enable case-insensitive sorts, to sort on subsets of fields, and to enable special user-supplied comparison functions. The sort can be used with filters and field maps, and it is extremely fast. DbiSortTable is supported by SQL drivers, but a SQL table can serve only as a source table, not as a destination table.
The sort engine uses language driver-defined collating sequences to accommodate the character sets of different languages.
