idb-connector

Node.js iDB Connector

The Node.js iDB Connector is a Node.js DB2 driver open source project from IBM.

Installation

    npm i idb-connector

Then you can require in your code, as shown below.

    const db = require('idb-connector');

Quick Example

Example 1: Fectching data using the exec() API

    const {dbconn, dbstmt} = require('idb-connector');
    const sSql = 'SELECT STATE FROM QIWS.QCUSTCDT';
    const connection = new dbconn();
    connection.conn("*LOCAL");
    const statement = new dbstmt(connection);

    statement.exec(sSql, (x) => {
      console.log("%s", JSON.stringify(x));
      statement.close();
      connection.disconn();
      connection.close();
    });

Example 2: Fectching data using the fetchAll() API

    const {dbconn, dbstmt} = require('idb-connector');
    const sSql = 'SELECT STATE FROM QIWS.QCUSTCDT';
    const connection = new dbconn();
    connection.conn("*LOCAL");
    const statement = new dbstmt(connection);

    statement.prepare(sSql, () => {
      statement.execute(() => {
        statement.fetchAll((x) => { 
          console.log("%s", JSON.stringify(x));
          statement.close();
        });
      });
    });

Example 3: Call stored procedures

    const idb = require('idb-connector'),
      {dbconn, dbstmt, IN, OUT, CHAR, CLOB} = idb;
    const sql = "CALL QXMLSERV.iPLUG512K(?,?,?,?)";
    const connection = new dbconn();
    connection.conn("*LOCAL");
    const statement = new dbstmt(connection);

    const ipc = "*NA";
    const ctl = "*here";
    const xmlIn = "<xmlservice><sh>system 'wrksbs'</sh></xmlservice>";
    const xmlOut = "";
    
    statement.prepare(sql, () => {
      statement.bindParam([
        [ipc, IN, CHAR],
        [ctl, IN, CHAR],
        [xmlIn, IN, CLOB],
        [xmlOut, OUT, CLOB]
      ], () => {
        statement.execute((out) => { // 'out' is an array of output params
          for(let i = 0; i < out.length; i++)
            console.log(out[i]);
          statement.close();
          connection.disconn();
          connection.close();
        });
      });
    });

Build

Note that building isn't necessary for end users and is more for developers looking to compile the native Node.js extensions (C code).

    git clone [e-mail]:IBM/nodejs-idb-connector.git
    cd nodejs-idb-connector
    npm install --build-from-source

Note: Gcc and python are required to compile the code.
