# How to Delete a Row: SQL Explained

Here’s SQL query to delete specific row /or group of rows explained for your use in projects.

## What’s Delete statement

Here’re a few points to consider before **DELETE** a row from a Table.

- The delete removes data from your chosen table.
- You go to all that effort crafting designs, building physical models, and coding a variety of tools to create and manage your data. With one little statement you can remove the lot.
- Okay, It removes unwanted data from a table.

## SQL Query to delete a row

```
DELETE FROM employee
WHERE joindate <= '2010-01-01'
```

## Here’s how delete query works

- For those of you who’ve used other databases that are somewhat lax about the standard and syntactical correctness, the word from is not optional.
- As [with the other DML statements](http://amzn.to/2oVH7Rk), the where clause is optional. [By not specifying a where clause](https://srinimf.com/2017/01/23/tricky-db2-question-on-select-statement/), all rows from a table will be removed.
- Using a where clause limits the rows deleted to those that match the specified criteria. **Related** : [238 top SQL queries](https://srinimf.com/2014/01/20/238-top-sql-queries/)
- One interesting aspect of the DB2 delete and update implementation is that you’ll see a warning if the criteria you specify don’t match any rows; that is
- **if your delete statement won’t actually delete any rows. You’ll see this warning**:
- SQL0100W No row was found for FETCH, UPDATE or DELETE; or the result of a query is an empty table. SQLSTATE=02000.
