# TINYBLOB

## Syntax

```bnf
TINYBLOB
```

## Description

A [BLOB](/docs/server/reference/data-types/string-data-types/blob.md) column with a maximum length of 255 (2⁸ - 1) bytes. Each `TINYBLOB` value is stored using a one-byte length prefix that indicates the number of bytes in the value.

## EXAMPLES

### TINYBLOB

Example of TINYBLOB:

```sql
CREATE TABLE tinyblob_example (
   description VARCHAR(20),
   example TINYBLOB
) DEFAULT CHARSET=latin1; -- One byte per char makes the examples clearer
```

```sql
INSERT INTO tinyblob_example VALUES
   ('Normal foo', 'foo'),
   ('Trailing spaces foo', 'foo      '),
   ('NULLed', NULL),
   ('Empty', ''),
   ('Maximum', RPAD('', 255, CHAR(7)));
```

```sql
SELECT description, LENGTH(example) AS length
   FROM tinyblob_example;
```

```sql
+---------------------+--------+
| description         | length |
+---------------------+--------+
| Normal foo          |      3 |
| Trailing spaces foo |      9 |
| NULLed              |   NULL |
| Empty               |      0 |
| Maximum             |    255 |
+---------------------+--------+
```

### Data too Long

When `SQL_MODE` is strict (the default), a value is considered "too long" when its length exceeds the size of the data type, and an error is generated.

Example of data too long behavior for `TINYBLOB`:

```sql
TRUNCATE tinyblob_example;

INSERT INTO tinyblob_example VALUES
   ('Overflow', RPAD('', 256, CHAR(7)));
```

```sql
ERROR 1406 (22001): Data too long for column 'example' at row 1
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://mariadb.com/docs/server/reference/data-types/string-data-types/tinyblob.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
