5 | Sql module (sq). This is a mysql implementation of an sql module.
6 |
7 | Status: NOT REVUED, NOT TESTED
8 |
9 | Note: this code has been heavily coupled to MySQL, and may need to be changed
10 | (to improve performance) if a new RDBMS is used.
11 |
12 | ******************/ /******************
13 | Filename : query_instructions.c
14 | Author : ottrey@ripe.net
15 | OSs Tested : Solaris
16 | Problems : Moderately linked to MySQL. Not sure which inverse
17 | attributes each option has. Would like to modify this
18 | after re-designing the objects module.
19 | Comments : Not sure about the different keytypes.
