Kem Tekinay: What I’ve learned about Valentina

In jumping back into Valentina, I’ve learned a number of things over the past few days that I thought I’d share. In no particular order…

– Valentina support (particularly Ruslan) has to be the most responsive support of any company in any country, ever.

– Valentina is fast. I mean, really fast. Using a flat-file database of 7 fields and 5 million+ records, and comparing it to other solutions like MySQL, PostgreSQL, SQLite and FileMaker Pro, Valentina beats them all in every test I can come up with. The only thing that is even close to the same range is MySQL, and only in some tests.

[NEW] REGEX_REPLACE() function.

In 4.5.1 release we have add a new REGEX_REPLACE() function  to Valentina Expresions, which can be used in Table Methods, SQL and therefore, in Reports.

Up to now, we was able to do searches with the help of REGEX operator:

… WHERE fld REGEX ‘ab.[cdf]*’

New function brings the awesome power of REGEX to manipulate by strings stored in the database! Now we can not only search using REGEX, but modify strings! You can do that in the

  • SELECT EXPR, …
  • UPDATE TABLE T SET fld = EXPR

where EXPR is REGEX_REPLACE() function or contains it as a part.

Read details about this function here.

VCursor Now Can UpdateRecord() of JOINs !!!

It is well known that Valentina offers to developer a very reach ADK API (about 1000 methods) in contrast to poor API of most dbs (e.g. near to 25 in mySQL).

One of nice feature is the ability to use VCursor class methods to MODIFY records of ServerSide & ReadWrite cursor. But for years we did have limit here: cursor can be ReadWrite only for single table SELECT. In the release 4.5 we remove this limitation! Now you can do UpdateRecord() and DropRecord() for cursors built over INNER JOIN of N tables!

Deprecated Convert_1_2() feature.

Also we are dropping Convert_1_2() feature of Valentina engine from 2.0 version to allow developers convert existed v1 databases. If somebody yet need convert v1 database to 2.0 format, he should use at first v4.3 for this task.

This function is removed from all Valentina ADKs and VStudio, DLL of VDK V1 engine  is removed from the vcomponents folder.

V4RB/V4MD Carbon deprecated in v4.5

We have decide to deprecated these two Carbon products in v4.5, which we have developed yet with help of CodeWarrior.

I think for REALbasic developers, this will not a problem, because few years REALbasic is a cocoa application itself, and works with xcode-made plugins.

For Director users, this means that v4.5 of V4MD mac, will not work with Director10, only with D11 and D11.5. If you still use D10, you can use v4.3 of V4MD that can be found here: http://valentina-db.com/download/prev_releases/

SqlEditor Improvements

SqlEditor becomes better. Added

* highlight of line with error;
* logs panel works better;
* tooltips that show info about Schema Object;
* code-folding, great when you type procedure or trigger;
* autocompletion menu has icons;
* if TAB panel is not visible, then buttons to execute queries and such, are shown in the sub-panel, so we can still use them.
