How to Compare Two Strings in SQL

To use SQL to compare two strings in a database, use the STRCMP() function. This function takes two arguments, which are the two strings you want to compare. It then returns an integer value that indicates the result of the comparison. If the two strings are equal, it will return 0. If the first string is greater than the second, it will return a positive number. If the first string is less than the second, it will return a negative number.


Let's look at a few examples of how this function can be used. Suppose you have two strings, 'Hello' and 'World'. If you wanted to compare these two strings, you would use the following query:

SELECT STRCMP('Hello', 'World');

This query would return the result -1, since the first string ('Hello') is less than the second string ('World').

Additional Info

The STRCMP() function is supported by most major databases, including MySQL, PostgreSQL, and SQL Server. However, the syntax may vary slightly depending on the database you are using. For more information, check out the documentation for your particular database.
