def sql = Sql.newInstance("jdbc:mysql://localhost:3306/mydb","user","pswd","com.mysql.jdbc.Driver") // delete table if previously created try { sql.execute("drop table PERSON") } catch(Exception e){} // create table sql.execute('''create table PERSON ( id integer not null primary key,firstname varchar(20),lastname varchar(20),location_id integer,location_name varchar(30) )''') // now let's populate the table def people = sql.dataSet("PERSON") people.add( firstname:"James",lastname:"Strachan",id:1,location_id:10,location_name:'London' ) people.add( firstname:"Bob",lastname:"Mcwhirter",id:2,location_id:20,location_name:'Atlanta' ) people.add( firstname:"Sam",lastname:"Pullara",id:3,location_id:30,location_name:'California' ) // do a query to check it all worked ok def results = sql.firstRow("select firstname,lastname from PERSON where id=1").firstname def expected = "James" assert results == expected // allow resultSets to be able to be changed sql.resultSetConcurrency = java.sql.ResultSet.CONCUR_UPDATABLE // change the data sql.eachRow("select * from PERSON") { it.firstname = it.firstname * 2 } // reset resultSetsConcurrency back to read only (no further changes required) sql.resultSetConcurrency = java.sql.ResultSet.CONCUR_READ_ONLY // do a query to confirm that our change actually worked results = sql.firstRow("select firstname,lastname from PERSON where id=1").firstname expected = "JamesJames" assert results == expected
