# Hello World
Also known as "Your First Table"
{% hint style="info" %}
Read about ["Setting up your environment"](/getting-started/setting-up-your-environment.md) before writing your first table.
{% endhint %}
## Content
* You will create a table called `books`
* You will insert a row
* You will query the inserted row
## Example Table
After having set-up your environment, we will create a table called **books.** For this, we will create a file named `books.ts` inside your `tables` folder. It will look like this:
{% code title="./public/tables/books.ts" %}
```typescript
export default function main() {
const { Table, Column } = SchemaJS;
return new Table("books")
.addColumn(new Column("id").string())
.addColumn(new Column("name").string())
.addColumn(new Column("author").string())
}
```
{% endcode %}
## Insert a row
After having created our table, we will run the engine by executing the following terminal command from the root of where our `SchemaJS.toml` is.
```
schemajs start
```
***
> Running `start` will open up a REPL after having initialized our database.
In our REPL, we will type `use` to access the table. For this, we will first need to access the database and then the table context.
`use("public")`
`use("books")`
and finally, after being in the context of the table **books,** we will proceed to run the following Javascript code.
```javascript
SchemaJS.insert({ id: "SOME-ID", "name": "The Lord of the Rings", "author": "J.R.R Tolkien" });
```
## Querying a row
Finally, to query a row, we can run the following JS command:
```javascript
SchemaJS.query(
new SchemaJS.QueryBuilder()
.and((and) => and.where("author", "=", "The Lord of the Rings"))
)
.then((res) => {
SchemaJS.print(JSON.stringify(res));
});
```
