类 NamedParameterStatement

java.lang.Object

com.lvonce.wind.sql.statment.PreparedStatementWrapper

com.lvonce.wind.sql.statment.NamedParameterStatement

所有已实现的接口:

java.lang.AutoCloseable, java.sql.PreparedStatement, java.sql.Statement, java.sql.Wrapper

public class NamedParameterStatement
extends PreparedStatementWrapper

This class wraps around a PreparedStatement and allows the programmer to set parameters by name instead of by index. This eliminates any confusion as to which parameter index represents what. This also means that rearranging the SQL statement or adding a parameter doesn't involve renumbering your indices. Code such as this:

 Connection conn = getConnection();
 String sql = "select * from my_table where name=? or address=?";
 PreparedStatement p = conn.prepareStatement(sql);
 p.setString(1, "bob");
 p.setString(2, "123");
 ResultSet rs = p.executeQuery();
 

Can be replaced with:

 Connection conn = getConnection();
 String sql = "select * from my_table where name=:name or address=:address";
 NamedParameterStatement p = new NamedParameterStatement(conn, sql);
 p.setString("name", "bob");
 p.setString("address", "123");
 ResultSet rs = p.executeQuery();
