Android Question Database load into listview how?

schemer · Feb 11, 2015

Ok, I am a noob at SQLite but managed to create a db. Now even though I have read a lot of stuff I am not sure I found the answer. My db will be "read only" and lots of examples are using the db in the more normal way of adding and deleting records. I will not be adding or deleting records nor will the end user. I also want to be sure I can even use the listview instead of maybe a better choice to load my records and data into. But for starters, how do I load the db and fill the list? I have tried the Dim SQL1 AS SQL etc but I am having trouble reading the data into the listview. What I want to do is be able to click on a list item and in turn access related data from another column to further process.
Thanks in advance,
schemer

android.database.sqlite.SQLiteException: no such table: mytable (code 1): , while compiling: SELECT * From 'mytable';

It should be:

B4X:

txt="SELECT * FROM mytable"

If mytable is a variable you use this:

B4X:

Dim mytable as String =schemer"
txt="SELECT * FROM '" & mytable & "'"

schemer,
it is helpfull to use some tools like SQLite Manager or something like this. There you can open your database and test your SQL statements.
https://code.google.com/p/sqlite-manager/ (just one idea, there are other...) and also helpful is may be http://www.sqlite.org/lang.html if you are stuck in your queries.

That didn't work. I even made a new simple db with 2 fields and 1 row of data. It seems I am having multiple problems all of a sudden and need to start over. Like my layout file is loading and older layout even if I modify and save it. I will keep at it till I get it.
Thanks,
schemer

Stefan,
I have SQLite Professional 3 and even though I am not a professional , I bought it years ago to support the developer. I will test my queries in my SQLite Pro and see what I get. The app seems to run and execute faster now even though I still end up with a blank screen.
Thanks,
schemer

p.s. My queries work fine inside of SQLite Professional.
