A native Scala library for using Sqlite3

Scalaqlite - A native Scala library for Sqlite3

Installation

Execute ./build.sh then copy

target/scala-2.10/scalaqlite-assembly-0.5-SNAPSHOT.jar
target/native/libscalaqlite.so

To your project 'lib' directory

Description

This library is intended to give a very Scala-ish interface to Sqlite. For example, you can use the follwing code to print all the rows in table "foo" with the columns separated by spaces:

for (row <- db.query("SELECT * FROM foo;"))
    println(row.map(_.toString).mkString(" "))

Or if you want to add up the values of the first column, you can do this:

for (row <- db.query("SELECT * FROM foo;")) {
    row(0) match {
        case SqlInt(i) => sum += i
        case _ => throw new Exception("expected an int")
    }
}

Note that sbt doesn't handle setting java.library.path yet, so you have to run the tests like this:

LD_LIBRARY_PATH=./target/native sbt test

If you want to avoid compiling the native code and setting LD_LIBRARY_PATH, at the cost of some performance, check out the jna branch.
