For example, one parameter that was made dynamic was the 'tape retention in days' (the number of days that the backup is kept on the tape media without overwriting the existing contents in the production environment). This improved performance and reduced downtime. In ASE 15.0, many parameters that had been static (which required server reboot for the changes to take place) were made dynamic (changes take effect immediately). It included support for partitioning table rows in a database across individual disk devices, and 'virtual columns' which are computed only when required. Also added was compressed backups, unichar UTF-16 support and multiple logical page sizes 2K, 4K, 8K, or 16K. In 2001, ASE 12.5 was released, providing features such as dynamic memory allocation, an EJB container, support for XML, Secure Sockets Layer (SSL) and LDAP. In addition, cache partitions were added to improve performance.

Merge joins were added, previous all joins were nested loop joins. In 1999, ASE 12.0 was released, providing support for Java, high availability and distributed transaction management. Query optimization is now delayed until a cursor is opened and the values of the variables are known. A lock timeout option and task-to-engine affinity were added, Indexes could now beД¬reated in descending order on a column, readpast concurrency option and repeatable read transaction isolation were added. In 1998, ASE 11.9.2 was rolled out with support for data pages locking, data rows (row-level locking), distributed joins and improved SMP performance. The Logical Process Manager was added to allow prioritization by assigning execution attributes and engine affinity. Sybase 11.5 added Asynchronous prefetch, case expression in sql, the optimizer can use a descending index to avoid the need for a worktable and a sort. Starting with version 11.5 released in 1996, Sybase moved to differentiate its product from Microsoft SQL Server by renaming it to Adaptive Server Enterprise. In 1995, Sybase released SQL Server 11.0. Version 10 and onwards uses CTLIB (ClienT LIBrary). Prior to version 10, DBLIB (DataBase LIBrary) was used. Sybase provides native low-level programming interfaces to its database server which uses a protocol called Tabular Data Stream. Microsoft continued on with Microsoft SQL Server. Sybase released Sybase SQL Server 10.0, which was part of the System 10 product family, which also included Back-up Server, Open Client/Server APIs, SQL Monitor, SA Companion and OmniSQL Gateway. In 1993, the co-development licensing agreement between Microsoft and Sybase ended, and the companies parted ways while continuing to develop their respective versions of SQL Server. This release included internationalization and localization and support for symmetric multiprocessing systems. Microsoft and Sybase sold and supported the product through version 4.2.1.

In 1988, SQL Server for OS/2 was co-developed for the PC by Sybase, Microsoft, and Ashton-Tate. Originally developed for Unix operating system platforms in 1987, Sybase Corporation's primary relational database management system product was initially marketed under the name Sybase SQL Server.
