## Overview
|
||||
|
||||
`SELECT` retrieves rows from one or more tables. It is the most frequently used SQL statement.
|
||||
|
||||
## Basic Syntax
|
||||
|
||||
```sql
|
||||
SELECT column1, column2 FROM table_name WHERE condition ORDER BY column1 ASC LIMIT 10;
|
||||
```
|
||||
|
||||
## Examples
|
||||
|
||||
### Get All Rows
|
||||
|
||||
```sql
|
||||
SELECT * FROM users;
|
||||
```
|
||||
|
||||
### Select Specific Columns
|
||||
|
||||
```sql
|
||||
SELECT id, name, email FROM users;
|
||||
```
|
||||
|
||||
### Filter with WHERE
|
||||
|
||||
```sql
|
||||
SELECT * FROM posts WHERE is_published = 1;
|
||||
```
|
||||
|
||||
### Multiple Conditions
|
||||
|
||||
```sql
|
||||
SELECT * FROM posts WHERE is_published = 1 AND category = 'technology';
|
||||
```
|
||||
|
||||
### Sorting
|
||||
|
||||
```sql
|
||||
SELECT * FROM posts ORDER BY created_at DESC;
|
||||
```
|
||||
|
||||
### Pagination
|
||||
|
||||
```sql
|
||||
SELECT * FROM posts ORDER BY created_at DESC LIMIT 10 OFFSET 20;
|
||||
```
|
||||
|
||||
`LIMIT` caps the number of rows returned. `OFFSET` skips the first N rows — useful for pagination (page 3 with 10 items per page = `LIMIT 10 OFFSET 20`).
|
||||
|
||||
### JOIN
|
||||
|
||||
```sql
|
||||
SELECT posts.id, posts.title, users.name AS author
|
||||
FROM posts
|
||||
JOIN users ON posts.user_id = users.id
|
||||
WHERE posts.is_published = 1
|
||||
ORDER BY posts.created_at DESC;
|
||||
```
|
||||
|
||||
### Aggregation
|
||||
|
||||
```sql
|
||||
SELECT category, COUNT(*) AS total
|
||||
FROM posts
|
||||
GROUP BY category
|
||||
ORDER BY total DESC;
|
||||
```
|
||||
|
||||
## Using SELECT via the API
|
||||
|
||||
For simple reads, use the [CRUD GET endpoint](/docs/api-reference/crud/get) — it handles filtering, sorting, and pagination through query parameters without writing raw SQL.
|
||||
|
||||
For complex queries (JOINs, aggregations, subqueries), use the [SQL API](/docs/api-reference/sql/options):
|
||||
|
||||
```javascript
|
||||
const result = await datasquirel.api.sql({
|
||||
key: process.env.DATASQUIREL_API_KEY,
|
||||
params: {
|
||||
query: "SELECT posts.id, posts.title, users.name AS author FROM posts JOIN users ON posts.user_id = users.id WHERE posts.is_published = 1 ORDER BY posts.created_at DESC LIMIT 20",
|
||||
},
|
||||
});
|
||||
```
