Progress
Embedded SQL-92
Guide and Reference
Introduction
The database types supported in Progress SQL-92 have two representations:
The database storage representation refers to the way a value is stored in the database. The host language representation refers to the way a value is represented in the C Language. Progress SQL-92 performs the necessary data conversions from one form to another. The application does not manage database storage representation.
See Chapter 2, “SQL-92 Language Elements,” in the Progress SQL-92 Guide and Reference for additional information on supported data types.
The next sections discusses the different categories of data types supported by Progress SQL-92 and how you use them in ESQL programs as INPUT and OUTPUT host variables.
