## Syntax

```bnf
>
```

## Description

Greater than operator. Evaluates both SQL expressions and returns `1` if the left value is greater than the right value and `0` if it is not, or `NULL` if either expression is `NULL`. If the expressions return different data types, (for instance, a number and a string), performs type conversion.

When used in row comparisons these two queries return the same results:

```sql
SELECT (t1.a, t1.b) > (t2.x, t2.y) 
FROM t1 INNER JOIN t2;

SELECT (t1.a > t2.x) OR ((t1.a = t2.x) AND (t1.b > t2.y))
FROM t1 INNER JOIN t2;
```

## Examples

```sql
SELECT 2 > 2;
+-------+
| 2 > 2 |
+-------+
|     0 |
+-------+

SELECT 'b' > 'a';
+-----------+
| 'b' > 'a' |
+-----------+
|         1 |
+-----------+
```

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/sql-structure/operators/comparison-operators/greater-than.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.
