[Sybase] Compiled objects

Compiled objects are created from source text, which are SQL statements that
describe and define the compiled object. When a compiled object is created,
Adaptive Server:
1 Parses the source text, catching any syntactic errors, to generate a parsed
tree.
CHAPTER 1 SQL Building Blocks
Transact-SQL User¡¯s Guide 5
2 Normalizes the parsed tree to create a normalized tree, which represents
the user statements in a binary tree format. This is the compiled object.
3 Stores the compiled object in the sysprocedures table.
4 Stores the source text in the syscomments table.
Note If you are upgrading from Adaptive Server version 11.5 or earlier,
and you have deleted source text from syscomments, you must restore the
deleted portions before you upgrade. To do so, follow the process in the
installation documentation for your platform.
