Hello Experts,
I am using ISNULL function to get the column to populate from two columns which do not have a Null.

Example ISNULL(ColumnA,ColumnB) as ABC  Polulates ColumnB Value in the Column 'ABC' when columnA is null. Now we have some rows in columnA that is empty space like ' ' instead of a Null.  What changes do I need to make to my SQL so it will populate ColumnB value in ABC when the ColumnA is an empty space instead of a null.

Issue is below:

ColumnA    ColumnB     ABC
  NULL           Hello         Hello
  '  '                 Hello          '   '

Expected Solution

ColumnA    ColumnB     ABC
  NULL           Hello         Hello
  '  '                 Hello         Hello

Thanks in advance
