Synchronous Connection and query handling for node-firebird.

Sometimes we need to do synchronous proccess instead of natural asynchronous with callback in query and data processing. Manukdadali wrap functionality of node-firebird and make it posible to use synchronously.

Installation

npm install manukdadali

Usage

const fb = require('manukdadali');

Config

const config = {
	host : 'localhost',
	database : 'MYDB.FDB',
	user : 'SYSDBA',
	password : 'masterkey'
};

Connect & Query

do this in async function

process.stdout.write("connecting to FirebirdSQL Server...");
let conn = await fb.connect(config);
console.log("\x1b[32m", "[Connected]", "\x1b[0m");

try {

	process.stdout.write('doing first query...')
	let rows = await conn.query('SELECT FIRST 10 * FROM mytable');
	console.log("\x1b[32m", "[OK].", "\x1b[0m");

	console.log(rows);

} catch(err) {
	throw err;
} finally {
	conn.close();
}

Transaction

do this in async function

process.stdout.write("connecting to FirebirdSQL Server...");
let conn = await fb.connect(config);
console.log("\x1b[32m", "[Connected]", "\x1b[0m");

process.stdout.write("staring transaction...");
await conn.BeginTransaction(fb.ISOLATION_READ_COMMITED);
console.log("\x1b[32m", "[Ok]", "\x1b[0m");

try {

	process.stdout.write("updating data...");	
	await conn.query("UPDATE mytable QUERY");
	console.log("\x1b[32m", "[Ok]", "\x1b[0m");	

	process.stdout.write("committing transaction...");	
	await conn.commit();
	console.log("\x1b[32m", "[Ok]", "\x1b[0m");

} catch(err) {
	throw err;
} finally {
	await conn.close();
}
