I have never used firebird and therefore wanted to know how it fits when
compared to MySQL in terms of:
ANSI SQL compliance
Triggers
Row level (not statement level) before and after insert, update and delete, as
well as database level triggers.
Foreign Keys
Stored Procedures
In all
Stephane,
It is logical for me, since before inserting, it needs to know if
similar record already exists (to be update). Sso, more operations are
being done (more disk I/O) compared to a single insert.
i was thinging than during an update or insert, the engine try first to
insert
Macro,
I find a situation that Firebird's generated code don't run because the
CROSS
APPLY is used. The issue is generated because I need to create a query inside
the where clause. I'll show the code that runs and part of the code that
brings the issue,
Firebird doesn't have any function
Ekso,
I used to use the C++ Builder PDFCanvas to directly create PDF files from
code.
You posted this to the *Firebird* support list; What does this have to do with
Firebird?
