Question

I’m trying to run a statement on sqlite database from android…I wish to return some records from a table which lastChagedDate bigger than the date I give.

Let’s say I have this:

private String ending_date = "2012-01-01 08:24:59";

roadmapSyncStmt = "SELECT * FROM roadmap WHERE lastChangedDate > '"+ ending_date +"'";

The roadmapSyncStmt is the one I will execute on sqlite table full of dates.
The statement will look something like:

SELECT * FROM roadmap WHERE lastChangedDate >"2012-01-01 08:24:59"

And when I run I get this error:

sqlite returned: error code = 1, msg = near “2012”: syntax error

and no data in cursor even though my database contains plenty of data which respects this condition. Does someone know what I do wrong?

Answer 1

You should enclose your date value in single quotes, not double quotes. Like this:

SELECT * FROM roadmap WHERE lastChangedDate > '2012-01-01 08:24:59'

Whilst you are learning, I recommend that you install a PC base SQLite editor, for example “SQLite Database Browser” which you can find on SourceForge. It’s much quicker and easier than testing in your app. I would go so far as to say that all of the DB development, testing, query creation etc should be done on your PC then it’s pretty much a copy/paste exercise to get it into your app.

Good luck.
