Mybaits did two things
One is the ORM, Object - Relationl Mapping, Mapping database objects and Java objects.
Another is the separation of SQL and Java, enhance the readability of SQL.

If you want to compare with JPA, mybatis query is relatively flexible, but this is the advantages and disadvantages, advantage is flexible, defect is not controllable, the same as framework, framework is not only promote efficiency, also write garbage code rules

Switch the connection, access the first think you have a better way, but to write SQL, you see the following two which is more clear

 SQL +="select NVL (t1)" + map. Get (" typ ") + ", '-') \ "typName ", \ r \ n "+ 
"To_char (count (1)) " typNum \ ", \ r \ n "+ 
"'" + map. Get (" typ ") + "' " _typCondition \ \ r \ n "+" 
"From bbb_base_bbb t1 \ r \ n +" 
"Where 1=1 \ r \ n" + 
='20191118'. "and t1 acct_date \ r \ n" + 
"" + map. Get (" sqlCondition") + "\ r \ n" + 
"Group by NVL (t1)" + map. Get (" typ ") + ", '-') \ r \ n "+ 
"The order by count (1) the desc"; 

 select NVL (t1) $typ $, '-') "typName," 
To_char (count (1)) "typNum," 
'${typ} "_typCondition 
"The from BBB. Base_bbb t1 
Where 1=1 
And t1. A_date='20191118' 
The ${sqlCondition} 
Group by NVL (t1) ${typ}, '-') 
The order by count (1) desc 

XML format for 5 seconds enough know SQL to write what, if it is hundreds of lines of more obvious, because you can't stick Java string directly into the pl/SQL execution, on the console print, written in the Java logic is also can't see,

As for the 4th floor said six files trival, if you want, just need to XML file can run zero configuration,
