quick novice question(s)
« on: August 23, 2015, 04:05:31 am »
hi-

I bought a few delphi books (7) and older.
Can I use just lazarus controls for db, or do I need zeosdb controls too?
Do the lazarus controls mimic the db controls in delphi  7 or earlier?
For i.e. if  I read in my delphi 7 or earlier books how the db works am I in a sense learning how the lazarus db work too?

Do data sets, fields, tquery,ttable all work the same as in older delphi yes|no
Lastly, there is no data module yet...correct?
I guess in a general sense I am wondering if everything mostly works the same.
borland products used to have a cool help system, and I am just wondering if my old delphi books
can be substituted for a help system.

Thanks for any input. I have been reading a little pascal and old delphi books lately getting ready to code.
I mostly worked on C++ and Tcl/TK this past year and used a C++/Firebird library for my hobby.
Thanks again,
jim

Hi-

I read that for firebird or postgresql that those db's are supported without having to use zeos (unless you want to).

I am going to just try it out. No need to reply to my questions.
I might be able to figure it out as I go.
It is coming back to me that the properties editor is a visual clue.

maybe I will download lazarus soon. I will probably have a blast.

thx,
jim

Hi-

I just wanted to answer my question on data modules.
yes, there are data modules.
I never really used them before. This time I will!
I fooled with delphi before I took formal programming courses.
I never created anything really cool back then.

This time I will do much better.
thx

Hi-

I am very impressed with the help system. VERY COOL. It has been a while since I played with Lazarus, and I didn't realize they added a help system.

Everything I wondered about is available now including help system, data modules, and data aware components.

I can't wait to practice.

THANKS!

Lazarus is sufficient, there are sqlDB components and others built-in

Do the lazarus controls mimic the db controls in delphi  7 or earlier?
Yes

For i.e. if  I read in my delphi 7 or earlier books how the db works am I in a sense learning how the lazarus db work too?
Yes

Yes

Yes

Yes
A bit confusing answer because of so many negations: Lazarus does have a TDataModule.
