#What is it ?

sql-Moduleon is a very simple template engine for .sql, It is running in node.js

• no sql file loading, no database query execution
• just the parsing of your sql template

###Logic

• Write your .sql with templates tags
• Load your .sql files
• Transform your sql into a template function and generate requests <-- sql-Moduleon's job
• Pass those requests to your query engine

#Available templates tags

• Condition

    {{? value }} SELECT * FROM table {{?}}

  will add the sql inbetween the tags only if the condition is fullfilled

• Value

    SELECT * FROM table WHERE id = {{= value }}

  will replace this tag by a sql parameter (?) and add value to the values array

• Javascript Code

    SELECT * FROM {{ out += '"Table"'; }}

  simply throw in javascript code in the template function

#Usage

var moduleon = require('sql-moduleon');
moduleon.setConfig({engine:'pg'});

var fs = require('fs');
var sql = fs.readFileSync('./your/sqlfile.sql').toString();

var sqlTemplateFunction = moduleon( 'filename' , sql );
var sqlRequest = sqlTemplateFunction({ key : value });

//use your DB engine to execute the generated request
db.query(sqlRequest.sql, sqlRequest.values);

sql-Moduleon remembers the template from one use to the other and you can parse your sql only once

var sqlt = moduleon( 'filename' )
if( sqlt === false){
	sqlt = moduleon( 'filename' , sql );
}
