hi,

if we use MySQL or PostgreSQL we must buy a License, but "where" to buy and how much does it cost

hi Serge,

i ask while some "Open-Source" ask "Commercial" Product for License.

now Alaska want me "pay" for PGDBE "Wrapper" (for PostgreSQL) which is Part of PRO Version ( since begin 2012 )
https://www.alaska-software.com/product ... t-list.cxp

it is new for me that a Company sell a Product and want to have Money, every Year, to use a "Wrapper" for a "Open-Source" Product
is it possible that Alaska must pay for License as they sell a ISAM "Wrapper" for PostgreSQL ? or want they just make Money ...

Hi Jimmy,

I use MySQL (free) for many years and support came from HMG...!

hi,

thx for Answer

as i know MySQL is using GPL License, which means you need to purchase a commercial license to distribute proprietary code that uses those libraries.

PostgreSQL use MIT license, where you "only" must include MIT License TEXT with Copyright

---

the Question is "where" i have to "pay" for it to use "Wrapper" to connect to Backend
Alaska want me NOW to "buy" a License to use PGDBE which is Alaska Way to connect to Backend using ISAM Style

Hi,

In my understanding, MySql is free:
1. If MySql (community) is downloaded directly on the client computer and installed.
2. If you do not use libmysql.dll to access MySql.

If you use libmysql.dll for access, then your source code also needs to be under GPL.

Workaround:
1. You can use SQLMIX as an RDD to access MySql, MariaDB and the like which is native harbour and It is equally fast and uses ODBC connection and does not use libmysql.dll.
2. You can use open source database tool like Dbeaver which allows you to connect directly to all kinds of RDBMS and use as workbench.

This is what I have understood, I may be wrong. Please look into the licensing terms more thoroughly before taking any decision.

Warm regards,

Jayadev
