Sybase Features

Does anybody know if Common Table Expressions and User-defined functions (not from Java) are supported on Syba开发者_开发百科se 12.5? I'm trying but could not seem to make these work. Thanks guys.

Both are not supported by ASE 12.5

You can use stored procedure instead of functions. I am not sure about what you are referring to by saying common table expressions

Sorry I have to disagree. Microsoft SQL Server is based on Sybase 7.0. So there may not be Common Table Expressions and User-Defined Functions, there are equivalent ways to do the same thing.

For example CTE can be done either in nested queries or via temp tables using a number sign (#) in front of the table name.

For User Defined Functions, create a stored procedure with simple SQL code and call it via the exec function for example "exec my_sql_code". This allows nesting of stored procedures.

Good SQL, good night.
