The SYBASE ADVANCED TRANSACT-SQL CODING TECHNIQUES course provides the students with a comprehensive explanation of the manner by which to write effective and highly efficient code for the SYBASE relational database management system. The course begins by teaching advantageous coding practices, and additionally discusses debugging techniques, sorting, applying conditional logic to data, combining data from multiple sources, statistical manipulation and formatting and presentation techniques. The class will cover, through detailed lectures and corresponding lab assignments, the advanced aspects of programming techniques of Transact-SQL not covered in the standard Introduction to SYBASE class. Upon completion of the course, the student will have a detailed knowledge of all aspects of advanced SYBASE coding, and will be able to write very efficient SYBASE programs.
Sybase Training Objectives:
Upon successful completion of this course, participants will be able to employ advanced coding techniques to solve common business programming functions. The students will readily be able to code highly efficient SQL applications.
Sybase Training Prerequisites:
The student should have attended the Introduction to SYBASE and Transact_SQL Class, or the student should have obtained the equivalent level of knowledge.
Sybase Training Audience:
This course is recommended for applications programmers, systems programmers, database administrators, application developers and all other related personnel who require an in depth understanding of the advanced SYBASE Transact-SQL coding techniques.
Course duration:
5 days
The first day of the class will be devoted to strengthening the participants' ability to write detailed and effective SYBASE code. The next four days build upon this basic knowledge to provide in depth lectures and labs in order to explain all of the techniques to utilize in order to create the most effective code.
