How to Enter Embedded SQL Package Specifications
Once you have set up an Ada program library, you must add four Embedded SQL units to your library. The units are package specifications that describe to the Ada compiler all the calls that the preprocessor generates. The source for these units is in the files:
ii_system:[ingres.files]eqdef.ada
ii_system:[ingres.files]eqsqlca.ada
ii_system:[ingres.files]eqsqlda.ada
Once you have defined your current program library using the acs set library command, you should enter the three units into your program library by issuing the following commands:
copy ii_system:[ingres.files]eqdef.ada, eqsqlca.ada,-
eqsqlda.ada []
ada eqdef.ada,eqsqlca.ada,eqsqlda.ada
delete eqdef.ada.,eqsqlca.ada.,eqsqlda.ada
You do not have to take the last step if you intend to compile the closure of a particular program from the source files at a later date. However, you should not modify an Embedded SQL definition file if it is left in your directory.
You need only enter the four Embedded SQL units once into your program library. Of course, if a new release of Embedded SQL/Ada includes modifications to the files "eqdef.ada," "esqlca.ada," or "eqsqlda.ada," you should copy and recompile the files.
If you display the new unit information, you will find the four unit names "ESQL," "ESQLDA," "EQUEL," and "EQUEL_FORMS" in the library. For example, by issuing:
acs dir esql*,equel*
the three unit names will be displayed.
