Class CachedPreparedStatement

java.lang.Object
org.jivesoftware.database.CachedPreparedStatement
public class CachedPreparedStatement extends Object
Allows PreparedStatement information to be cached. A prepared statement consists of a SQL statement containing bind variables as well as variable values. For example, the SQL statement "SELECT * FROM person WHERE age > ?" would have the integer variable 18 (which replaces the "?" character) to find all adults. This class encapsulates both the SQL string and bind variable values so that actual PreparedStatement can be created from that information later.
