java - Assigning variable to column with same name as another in a different table from JOIN -

-

i doing join retrieve data database , assigning variables

rs = select.executequery("select pk_task, pointperson, task.scrumid, story.scrumid, product.scrumid [task] " +     "inner join [story] on storyid=pk_story inner join [product] on productid=pk_product product.deleted!=1");

to retrieve data:

while(rs.next()) {     string taskid = rs.getstring("pk_task"); }

but how data columns have same name on different tables:

while(rs.next()) {     long taskscrumid = rs.getlong("task.scrumid"); }

results in:

com.microsoft.sqlserver.jdbc.sqlserverexception: column name task.scrumid not valid.

either use getstring(int) or use task.scrumid task_scrum_id , getstring("task_scrum_id"). prefer latter approach.

so, in case, task be

string taskid = rs.getstring(3)

or query 

select.executequery("select pk_task, pointperson, task.scrumid task_scrum_id, ...  string taskid = rs.getstring("task_scrum_id")
