Sure, post to an appropriate newsgroup, and be sure to say which OS, 
database, and SQL binding you are using.

But more important, if you are using an RDBMS, such questions require 
knowing the schema for the database.  In an RDBMS, you can add data to a 
virtual table, and it may work--but not efficiently.  To get efficient 
updates, you usually have to add a (real) index to a real table.  And 
that question is appropriate to the right RDBMS group, but not here.

You are welcome.  But please do not post any similar questions here, 
unless they are directly related to Ada or to an Ada binding to a 
particular database.  (You may have thought that this question was Ada 
related, but as you can see from the partial answer, it definitely is not.)
