How can I get rid of comma's if not part of a "valid" value?
For instance, I have a 'Sample' table that contains a 'State' column
The values in the column could be empty, contain states separated by a comma, or contain one or more single commas. I want to remove those, while keeping states with a comma separating them.
Thoughts...?

CURRENT
TABLE = 'Sample'
COLUMN = 'State'

State
Alabama
, 
Alaska, Arizona
California, Colorado
empty string
, 
empty string
, , 
Deleware, Georgia, Utah

DESIRED RESULTS

State
Alabama
empty string 
Alaska, Arizona
California, Colorado
empty string 
empty string 
Deleware, Georgia, Utah

DELETE FROM mytable WHERE LTRIM(REPLACE(State, ',', '')) = ''


Note this may not be too fast

Why delete? As per OPs required output it should be just this


UPDATE Sample
SET State = ''
WHERE LEN(LTRIM(REPLACE(State,',','')))=0

Sorry I thought from the output that the blank lines were removed.

In that case you can use WHERE clause not DELETE statement
