Chapter Type Conversion
Table of Contents
SQL statements can, intentionally or not, require the mixing of different data types in the same expression. ProtonBase has extensive facilities for evaluating mixed-type expressions.
In many cases a user does not need to understand the details of the type conversion mechanism. However, implicit conversions done by ProtonBase can affect the results of a query. When necessary, these results can be tailored by using explicit type conversion.
This chapter introduces the ProtonBase type conversion mechanisms and conventions. Refer to the relevant sections in Chapter 7 and Chapter 8 for more information on specific data types and allowed functions and operators.
