Compile

alasql.compile()

Alasql can precompile statements. It is a kind a "prepare" in other SQL databases.

To compile statement use:

   var stmt = alasql.compile(sql)

Then run the statement:

   stmt([parameters array], callback)

Here is the example how to calculate sum of numbers > 2 from [1,2,3,4,5]:

    var data = [{a:1},{a:2},{a:3},{a:4},{a:5}];

    // Compile
    var mysum = alasql.compile("SELECT VALUE SUM(a) FROM ? WHERE a > 2");

    // Run
    var res = mysum([data])
