mysql命令

一、查詢mysql timeout相關的變量值

SHOW VARIABLES LIKE "%timeout%"

二、能夠插入部分字段的值（id字段自增）

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

三、建立表

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));";
  四、插入語句

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

五、條件查詢語句

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