Query-Helper, A simple java class to create string query
Below are the examples of how to use it.
example of the usage:
- Usage:
- Query.select(DBMS.DBMS_MYSQL,“name”).from(“people”).where(“name like ‘romo’”).toString();
- will result "select name from people where name like ‘romo’ "
-———————————————————————————————————————————————————————————————————————————— - Usage:
- String [] tAttributes = {"name", "age"};
- String [] tTables = {"people", "people_detail"};
- QuerySelect result = Query.select(DBMS.DBMS_MYSQL, tAttributes).from(tTables).where(“name like ‘romo’”).toString();
- will result "select name , age from people , people_detail where name like ‘romo’ "
-———————————————————————————————————————————————————————————————————————————— - Usage:
- Query.update(DBMS.DBMS_MYSQL, “people”).set(“first_name”, “‘romo’”).where(“id = 1”).toString();
- will result “update people set first_name = ‘romo’ where id = 1”
-———————————————————————————————————————————————————————————————————————————— - usage:
- String[][] tMapValue = { {"first_name","’romo’"} , {"last_name","’alen’"}};
- Query.updateMap(DBMS.DBMS_MYSQL,“area”, tMapValue,“id = 4”).toString();
- will result “update area set first_name = ‘romo’,last_name = ‘alen’ where id = 4”
-———————————————————————————————————————————————————————————————————————————— - usage:
- String [] tAttributes = {"first_name", "last_name"};
- String [] tValues = {"’romo’", "’alen’"};
- Query.insertInto(DBMS.DBMS_MYSQL,“area”).values(tAttributes, tValues).toString();
- will result: “insert into area(first_name,last_name) values (‘romo’,‘alen’)”
-———————————————————————————————————————————————————————————————————————————— - usage:
- String[][] tMapValue = { {"first_name","’romo’"} , {"last_name","’alen’"}};
- Query.insert(DBMS.DBMS_MYSQL, “area”, tMapValue).toString();
- will result: “insert into area(first_name,last_name) values (‘romo’,‘alen’)”
-———————————————————————————————————————————————————————————————————————————— - usage:
- String[] tAttributes = {"first_name","last_name"};
- String[][] tValues = { {"’romo’","’alen’"} ,
- {"’yel’","’sico’"},
- {"’tri’","’dera’"}
- };
- Query.inserts(DBMS.DBMS_MYSQL,“area”,tAttributes, tValues).toString();
- will result "insert into area(name,filename) values (‘romo’,‘alen’),
- (‘yel’,‘sico’),(‘tri’,‘dera’)"
