idb-connector

Node.js iDB Connector for IBM i

The Node.js iDB Connector is an IBM i Node.js Db2 driver open source project from IBM

Installation

    npm i idb-connector

NOTE This package only installs on IBM i systems.

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

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

Quick Example

Example 1: Fetching 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(JSON.stringify(x));
      statement.close();
      connection.disconn();
      connection.close();
    });

Example 2: Fetching 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(`Result is : ${JSON.stringify(x)}`);
          statement.close();
        });
      });
    });

Example 3: Call stored procedures

    const {
      dbconn, dbstmt, IN, OUT, CHAR, CLOB,
    } = require('idb-connector');

    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 += 1) {
            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

Build Dependencies

Note: sqlcli header files, gcc, and python are required to compile the code.

    yum install sqlcli-devel
    yum group install 'Development tools' 
    yum install python2
