Data Types
Ingres tables consist of columns of data. The data type of the column indicates the type of information that is contained in the column and how Ingres handles the information. Variables, constants, and procedures that return values also use data types to indicate what type of data is accepted.
Vision and ABF both support the standard Ingres data types, with the exception of long varchar, long bit, byte, byte varying, and long byte.
Note: If a Vision frame is based on a table that has a column of one of those types, that column is not displayed or included in the query. The remaining columns in the table are displayed.
In addition to using standard Ingres data types, you can define record types and arrays. Record types and arrays (special kinds of data types) are discussed in detail in
Record Types.
