postgresqlHow do I determine the length of a string in PostgreSQL?

To determine the length of a string in PostgreSQL, you can use the LENGTH() function. This function takes a string as an argument and returns the length of the string.

For example, the following code block returns the length of the string Hello World:

SELECT LENGTH('Hello World');

Output example

11

The code consists of two parts:

1. SELECT: This statement is used to select data from a database.
2. LENGTH('Hello World'): This function takes a string as an argument and returns the length of the string.

For more information, please refer to the PostgreSQL Documentation.
