How to use the BIGINT function from sequelize

sequelize.BIGINT is a data type in the Sequelize library that represents a large integer value in a SQL database.

How does sequelize.BIGINT work?

sequelize.BIGINT is a data type provided by the Sequelize library for representing large integer values in a SQL database. To use sequelize.BIGINT, you first need to install and require the Sequelize library in your Node.js application: javascript Copy code {{{{{{{ const Sequelize = require('sequelize'); Once you have the Sequelize library, you can define a model for a table in your database using the define method. Here's an example of how you might define a table with a sequelize.BIGINT column: javascript Copy code {{{{{{{ class="!whitespace-pre hljs language-javascript">const MyModel = sequelize.define('MyModel', { myBigIntColumn: { type: Sequelize.BIGINT, allowNull: false } }); In this code, we define a new Sequelize model called MyModel with a single column called myBigIntColumn. This column is defined as a Sequelize.BIGINT data type, which represents a large integer value. We also set the allowNull option to false, which means that the column cannot be null. Once you have defined a model with a Sequelize.BIGINT column, you can use the sync method to synchronize the model with the database and create the table: javascript Copy code {{{{{{{ class="!whitespace-pre hljs language-javascript">MyModel.sync(); This code synchronizes the MyModel model with the database, creating the table and any necessary columns. sequelize.BIGINT is just one of many data types provided by Sequelize for working with SQL databases in Node.js. It is used to represent large integer values that cannot be stored as a regular INTEGER value.

const { Sequelize, DataTypes } = require("sequelize");

// create a new Sequelize instance
const sequelize = new Sequelize("mydatabase", "myusername", "mypassword", {
  host: "localhost",
  dialect: "postgres",
});

// define a model with a BIGINT column
const MyModel = sequelize.define("MyModel", {
  myBigIntColumn: {
    type: DataTypes.BIGINT,
    allowNull: false,
  },
});

// sync the model with the database and create the table
MyModel.sync()
  .then(() => {
    console.log("Table created successfully");
    // create a new record in the database
    return MyModel.create({
      myBigIntColumn: 123456789012345,
    });
  })
  .then((record) => {
    console.log("Record created successfully:", record.toJSON());
  })
  .catch((error) => {
    console.error("Error:", error);
  })
  .finally(() => {
    // close the database connection
    sequelize.close();
  });

In this example, we first create a new Sequelize instance with the configuration for a PostgreSQL database running on localhost with the specified username, password, and database name. We then define a new Sequelize model called MyModel with a single column called myBigIntColumn, which is defined as a DataTypes.BIGINT data type. We then use the sync method to synchronize the MyModel model with the database and create the table. Once the table is created, we use the create method to insert a new record into the table with a value of 123456789012345 for the myBigIntColumn column. If the record is successfully created, we log its details to the console. If there is an error, we log the error to the console. Finally, we close the database connection using the close method.
