mysql命令

1、查询mysql timeout相关的变量值

SHOW VARIABLES LIKE "%timeout%"

2、可以插入部分字段的值（id字段自增）

INSERT into weightTB(date,weightNum) values('2015-03-23 16:30:21','www')；

3、创建表

String createTB_sql = "CREATE TABLE "
                    + tbName
                    + "(date char(255)not null primary key,morningTime char(255),morningWeightNum char(5),nightTime char(255),nightWeightNum char(5));";
  4、插入语句

String date_insert_sql = "INSERT into " + tbName + "(date) values('"
                + strDate + "');";

5、条件查询语句

String select_sql = "select * from " + tbName + " where date='"
                + strDate + "'";
