How to use class in like clause in teradata?

In Teradata, you can use the class keyword in a LIKE clause to specify a character class. Here's an example of how to use the class keyword in a LIKE clause:

SELECT * FROM table_name WHERE column_name LIKE '[a-z]%'

In this example, the LIKE clause is looking for values in the column_name column that start with a lowercase letter. The [a-z] class specifies a character class that includes all lowercase letters from a to z.

You can use different character classes in the LIKE clause to match specific patterns in the data. Here are some common character classes you can use in Teradata:

• [0-9]: Matches any single digit
• [a-z]: Matches any single lowercase letter
• [A-Z]: Matches any single uppercase letter
• [a-zA-Z]: Matches any single letter, either lowercase or uppercase

By using the class keyword in a LIKE clause, you can create more complex and specific patterns to search for in your data.
