Data Types Used in Mimer SQL
The following sections explain how to compile applications using floating point data types, and what data types Mimer SQL uses internally and externally.
Compiling Applications Using Floating Point Data Types
OpenVMS supports various floating point types. Mimer SQL uses the types that the C compiler uses as default. Unfortunately, this differs between the Alpha and Integrity platforms.
F_FLOAT 4 bytes Used by Mimer on Alpha S_FLOAT 4 bytes Used by Mimer on Integrity G_FLOAT 8 bytes Used by Mimer on Alpha T_FLOAT 8 bytes Used by Mimer on Integrity D_FLOAT 8 bytes Not supported by Mimer H_FLOAT 16 bytes Not supported by Mimer
External Data Types Supported by Mimer SQL
Any value stored in the database may be read into host language variables as described in the Mimer SQL Programmer's Manual.
Mimer SQL will perform all the necessary conversions and will signal an error if the value to be converted is not compatible with the destination type.
