This chapter is subdivided into the following sections:
Overview
Data types
Values
Assignment rules
It has two parts. After an overview of the SESAM/SQL data types and their corresponding range of values, the first part provides you with all the information you need to know about data types with regard to defining table columns:
syntax
range of values defined by the data type
Compatibility between data types
In routines, the routine parameters and the local variables also have a data type.
The second part provides you with all the information you need for using the values of a data type:
syntax of the literals
rules for entering the values in table columns, routine parameters, and local variables
rules for using values in expressions and search conditions
rules governing data type compatibility and conversion during assignment
