< select id (selection SQL database)=" get Order By Condition (is ordered by condition acquisition
It is single) ", parameterClass (parameter type)=" java.util.HashMap ", resultClass (result type)="
java.util.HashMap">；
Structured query language sentence after configuration parameter can be such that select*from t_order where
Created>' 2017-01-01'and status=1</select>；
Wherein, in select id, select is the selection grammer of semi-automation ORM frame ibatis ORM frame, and id is
The unique identification (such as database-name t_order) of SQL database, parameterClass are dynamic in SQL query statement
State parameter, resultClass are the return values of SQL query statement, and parameterClass and resultClass are object tag
Fixed attribute.
