# VSIZE

Syntax

Description of the illustration vsize.gif

Purpose

`VSIZE` returns the number of bytes in the internal representation of `expr`. If `expr` is null, then this function returns null.

This function does not support `CLOB` data directly. However, `CLOB`s can be passed in as arguments through implicit data conversion.

See Also: "Datatype Comparison Rules" for more information

Examples

The following example returns the number of bytes in the `last_name` column of the employees in department 10:

    SELECT last_name, VSIZE (last_name) "BYTES"
      FROM employees
      WHERE department_id = 10;

    LAST_NAME            BYTES
