java sql.or().like

The method or() is used in SQL queries to combine multiple conditions using the OR operator. The like() method is used to search for a particular pattern in a string.

In Java, these methods can be used with JDBC (Java Database Connectivity) to execute SQL queries on a database. Here is an example:

String searchQuery = "SELECT * FROM employees WHERE first_name LIKE ? OR last_name LIKE ?";
PreparedStatement statement = connection.prepareStatement(searchQuery);
statement.setString(1, "%John%");
statement.setString(2, "%Doe%");
ResultSet resultSet = statement.executeQuery();

In this example, we are searching for employees whose first name contains "John" or last name contains "Doe". The % symbol is a wildcard character that matches any sequence of characters. The PreparedStatement class is used to prevent SQL injection attacks. The executeQuery() method returns a ResultSet object that contains the results of the query.
