同样的数据，通过cmd插入ORACLE数据库能正常的插入，但通过JDBC插入会报 ：值大于为此列指定的允许精度的错误，请各位大神帮我看看，十分感谢！！

往数据库写时就会有异常，而且写不进去。异常：the jar file mysql-connector-java-5.1.22-bin has no source attachment
这个地方不要这样用，
你可以把你的to_date(youdateval,'yyyy-MM-dd')这样看看。
这句话的问题,列MGR为NUMBER(4)
DAO设计模式我这么写关于JDBC的：
package cn.yla.dbc;import java.sql.Connection;
import java.sql.DriverManager;public class DatabaseConnection { private static final String DBDRIVER = "org.gjt.mm.mysql.Driver";
private static final String DBURL = "jdbc:mysql://localhost:3306/数据库名";
private static final String DBUSER = "root";
private static final String PASSWORD = "mysqladmin"; private Connection conn;
public DatabaseConnection(){
try {
Class.forName(DBDRIVER);
this.conn = DriverManager.getConnection(DBURL, DBUSER,
PASSWORD);
} catch (Exception e) {
e.printStackTrace();
}
}
public Connection getConnection(){
return this.conn;
}
public void close(){
if(this.conn != null){
try {
this.conn.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
不喜欢的话勿喷
