The Ada Compiler
After you enter the Embedded SQL packages into the Ada program library, you can compile the Ada file generated by the preprocessor.
The following example preprocesses and compiles the file "test1." Note that both the Embedded SQL/Ada preprocessor and the Ada compiler assume the default extensions.
esqla test1
ada/list test1
Note: Refer to the Readme file for any operating system specific information on compiling and linking ESQL/Ada programs.
VMS
As of Ingres II 2.0/0011 (axm.vms/00) Ingres uses member alignment and IEEE floating-point formats. Embedded programs must be compiled with member alignment turned on. In addition, embedded programs accessing floating-point data (including the MONEY data type) must be compiled to recognize IEEE floating-point formats.
The VMS default qualifier /g_float is not a standard and should not be used.
On Alpha systems, hardware support for D_float is only partial, the default has changed to G_float, and support for IEEE (IEEE 754-1985 standard for floating point arithmetic) has been added. Because of this, and because IEEE is available on other platforms and is recognized as an industry standard, Ingres for OpenVMS Alpha uses the IEEE format.
All programs and libraries should be compiled using the IEEE qualifier. Do not mix programs or libraries compiled with different qualifiers.
For example:
esqla prog.sa
ada /float=ieee prog
Failure to use the /float=ieee qualifier or the use of non-IEEE float numbers will result in unpredictable results when non-IEEE floats are used as keys or in restrictions.
