I have a column with values =0, >0, and null. If I have a condition where I want to select all values less than 0, including those null values, "<0" doesn't seem to include null values. Is this true? Thanks.

Hi Christine! Thanks for reaching out. Could you please explain your questions with more words? Thank you. Looking forward to your answer. Best, Tsvetelin

I have a column where there are numbers >0, =0, and null. If I do a WHERE clause with condition less than or equal to 0, like "column_name <= 0", will the results include both 0 and null values? Or it has to be "WHERE column_name =0 or column_name is null"? Thanks.

Hi Christine! You need two conditions. One checking for the records with value smaller or equal to 0 and another one checking for the null values Hope this helps. Best, Tsvetelin
