JAVA-SQL- Data Migration - ResultSets comparing Failing JUnit test
- by user1865053
I CANNOT get this JUnit Test to pass for the life of me. Can somebody point out where this has gone wrong. I am doing a data migration(MSSQL SERVER 2005), but I have the sourceDBUrl and the targetDCUrl the same URL so to narrow it down to syntax errors. So that is what I have, a syntax error. I am comparing the results of a table for the query
SELECT programmeapproval, resourceapproval FROM tr_timesheet WHERE timesheetid = ?
and the test always fails, but passes for other junit tests I have developed. I created 3 diffemt resultSetsEqual methods and none work. Yet, some other JUnit tests I have developed have PASSED. THE QUERY:
SELECT timesheetid, programmeapproval, resourceapproval FROM tr_timesheet
Returns three columns
timesheetid (PK,int, not null) (populated with a range of
numbers 2240 - 2282)
programmeapproval (smallint,not null) (populated with the
number 1 in every field)
resourceapproval (smallint, not null) (populated with a number
1 in every field)
When I run the query that is embedded in the code it only returns one row with the programmeapproval and resourceapproval columns and both field populated with the number 1.
I have all jdbc drivers correctly installed and tested for connectivity. The JUnit Test is failing at this point according to the IDE.
assertTrue(helper.resultSetsEqual2(sourceVal,targetVal));
This is the code:
