This includes support for Auto-increment, BLOB (Binary Large Objects), Currency, DateTime (timestamp), VarBinary, and VarChar field types. Null field support has also been added to give true SQL-style NULL handling for Visual FoxPro DBF tables. Support for true unique (candidate) indexes is now also available on DBF tables; this allows for better SQL optimization, the definition of primary keys, and the creation of referential integrity rules. Additionally, support for long field names with DBF tables has been added. In addition to supporting the robust and high-performance Advantage proprietary locking on the new table format, Advantage also supports Visual FoxPro compatibility locking, which allows you to use Advantage-enabled applications to share tables with existing Visual FoxPro applications that are not using Advantage. Support for Visual FoxPro-Compatible Collation Tables: Support has been added for Visual FoxPro-compatible collations for code pages 437, 620, 737, 850, 852, 857, 861, 865, 866, 895, 1250, 1251, 1252, 1253, and 1254. This includes the Visual FoxPro collations CZECH, DUTCH, GENERAL, GERMAN, GREEK, HUNGARY, ICELAND, MACHINE, NORDAN, POLISH, RUSSIAN, SLOVAK, SPANISH, SWEFIN, TURKISH, and UNIQWT. These collations can be used with Visual FoxPro tables and Advantage ADT tables. One benefit of these tables is that they provide the ability to give case-sensitive query and filter capabilities to normal character fields. In addition, they provide for better sorting characteristics when using characters with diacritics. They also provide support for expansion and contraction characters. For example, when using one of the Spanish collations, the character pairs "ch" and "ll" are handled and sorted as a single collation element. These collations are dynamically loaded on demand and do not have to be stamped into the server. |
