Convert() - (MySQL Misc)

The CONVERT() function is a MySQL function that is used to convert a value from one data type to another. In this tutorial, we'll cover the syntax, examples, and functionality of the CONVERT() function.

Syntax

The basic syntax for the CONVERT() function is as follows:

CONVERT(expression, type, conversion_options)

The expression parameter is the value that you want to convert. The type parameter is the target data type that you want to convert the value to. The conversion_options parameter is an optional parameter that allows you to specify additional conversion options.

Example

Here's an example of how to use the CONVERT() function in MySQL:

SELECT CONVERT(50, CHAR);

In this example, the value 50 is converted to the CHAR data type.

Output

When you run the query above, you will get the following output:

'50'

Explanation

In the example above, the CONVERT() function converts the value 50 to the CHAR data type. The resulting value is then returned as a string, in this case, the string '50'.

Use

The CONVERT() function is useful when you need to convert values from one data type to another. For example, you might need to convert a timestamp value to a string so that you can display it in a user interface.
