2. NULLIF is a little short than use a full IFF or CASE statement. SELECT. NULLIF(fb.org_story,'') AS pvt_story. FROM prod.facebook AS fb. But if the string has whitespace around it you might need to TRIM that also, thus I would be inclined to use: SELECT. NULLIF(TRIM(fb.org_story),'') AS pvt_story. FROM prod.facebook AS fb.The hidden culprit here is the presence of NULL values in the column referenced in the subquery. We need to note that NULL value will always be part of the output returned by the Distinct clause.

1. Like most SQL languages, comparing NULL = NULL does not return TRUE. In SnowFlake, it returns NULL, as does ANY comparison to a NULL value. The reason for this is tied to the convoluted history of SQL, and it has been well argued whether or not this is a good feature or not. Regardless, it's what we have.PRIMARY KEY. UNIQUE KEY.

Using a single INSERT command, you can insert multiple rows into a table by specifying additional sets of values separated by commas in the VALUES clause.

If you are want when ID is not null AND CATEGORY = 'A' then.
