This will throw the exception, since there is a duplication of ID (Bruce Scott has the ID 1). As with Statement objects, to execute a PreparedStatement object, call an execute statement: executeQuery if the query returns only one ResultSet (such as a SELECT SQL statement), executeUpdate if the query does not return a ResultSet (such as an UPDATE SQL statement), or execute if the query might return more than one ResultSet object. If it evaluates to FALSE, the loop ends. Formal theory. Including files is very useful when you want to include the same PHP, HTML, or text on multiple pages of a website. The syntax for functions like mysql.format may look similar to a prepared statement, but it is not and the escaping rules from this module are used to generate a resulting SQL string. Although sometimes defined as "an electronic version of a printed book", some e-books exist without a printed equivalent. As with Statement objects, to execute a PreparedStatement object, call an execute statement: executeQuery if the query returns only one ResultSet (such as a SELECT SQL statement), executeUpdate if the query does not return a ResultSet (such as an UPDATE SQL statement), or execute if the query might return more than one ResultSet object. of rows starting from a specified row with the help of LIMIT CLAUSE as: SELECT * FROM
