jrdc2

Hi All, I have a requirement to use a Raspberry PI as a Local DB server, but I need to support both Android and iOS clients. I was looking at this post: https://www.b4x.com/android/forum/threads/mariadb-does-not-wait-for-query-results.132054/post-833507, and it seems to be straightforward with...

Hello, in PDO you can use one liner(almost) to get the total nr of rows of your DB table $nRows = $pdo->query('select count(*) from blah')->fetchColumn(); echo $nRows; is there something similar for jRDC, so I do not need to fetch all data and then count it in my program, but let the server...

Hello, it's looks that importing data from mariadb with jRDC is very very strict, causing errors which take a lot of time to understand. (no offence, no doubt I'm the biggest cause) If I import via Select a row from DB and a column has date like yyyy-mm-dd, should the variable where this data...

Hello, Some strange is happening, I can't figure out what, it must be something very small or it is a bug. I have a few buttons,which are to do something else, but I misuse them for now to figure something out. Strange thing is that I get errors depending on who knows what. I'm just testing...

Hi all: I'm starting (at last) to work with B4XPages, so I've started to adapt the B4XPages + B4XDrawer example. I think I’ve seen more examples with php + mysql, but no projects with Jrdc2. Maybe the dummy data and the UI are too basic, but you can get some ideas. What do we need? - A...
