postgresqlHow do I use PostgreSQL regex to search for a specific pattern?

To use PostgreSQL regex to search for a specific pattern, you can use the ~ operator. For example, if you wanted to search for all strings that start with foo you can use the following query:

SELECT * FROM table_name WHERE column_name ~ '^foo';

This will return all strings that start with foo from the column_name column in the table_name table.

The parts of this query are:

• SELECT * FROM table_name - This is the standard SELECT query that returns all columns from the specified table.
• WHERE column_name ~ '^foo' - This is the regex search condition. The ~ operator is used to indicate a regex search and the ^foo pattern indicates that the search should return all strings that start with foo.
