Question

I am having table with 100 columns. here up to 50 to 60 columns contains NULL value in it. Now i need to Replace this NULL value to 0 in all 50 to 60 columns. I tried with the Update query as,

UPDATE [tableName] 
SET col1=0, col2 = 0, ... col60 = 0 
WHERE col1 IS NULL AND Col2 IS NULL ... Col60 IS NULL

Is there anyother Query to update these all 60 columns without specifying such columns or we have any other approach???

Answer 1

You have to specify all columns, but you can skip the WHERE clause and have one update deal with them all at once:

UPDATE [tableName] SET
  col1=COALESCE(col1, 0),
  col2=COALESCE(col2, 0),
  col3=COALESCE(col3, 0),
  col4=COALESCE(col4, 0),
