Please note in SQL-1 that test_number = 'TEST4P20 ' has a space and in SQL-2 there is no space test_number
= 'TEST4P20' has no space.
Is it not a bug?
I do not want the above queries to fetch the same results.
I check the data closely which does has a SPACE in the table. In which case, SQL-2 should have fetched no rows.
Does anyone not agree on this?
