Snowflake is not null.

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.To ensure that every employee has a salary value, you can add a NOT NULL constraint to the "salary" column. This constraint will prevent any null values from being inserted into the column, ensuring that every employee's salary is recorded accurately. The NOT NULL constraint provides an additional layer of data validation, ensuring that the ...4. If you keep going deeper in the docs, you'll find the explanation: Referential integrity constraints in Snowflake are informational and, with the exception of NOT NULL, not enforced.

If all arguments have NULL values, it returns NULL. Unlike ISNULL or IFNULL (NVL), COALESCE can accept more than two arguments. Below is an example of COALESCE function in SQL:

The 2 in the call NTH_VALUE(i, 2) specifies the second row in the window frame (which, in this case, is also the current row). When the current row is the very first row in the window frame, there is no preceding row to reference, so FIRST_VALUE() returns a NULL for that row.Snowflake NULL Handling Functions. You can use NULL functions to handle NULL values that may come as a part of your data. For example, you can use NULL functions to display zero in place of NULL on reports. Similarly, you can use a NULL function to handle divided by zero error in case of mathematical calculation.Snowflake supports defining and maintaining constraints, but does not enforce them, except for NOT NULL constraints, which are always enforced. Constraints are provided primarily for data modeling purposes and compatibility with other databases, as well as to support client tools that utilize constraints. For example, Tableau supports using ...

If the condition is NULL, then it is treated as FALSE. Examples¶ Here is an example of a Snowflake Scripting IF statement inside a stored procedure: In JSON, an object (also called a “dictionary” or a “hash”) is an unordered set of key-value pairs. TO_JSON and PARSE_JSON are (almost) converse or reciprocal functions. The PARSE_JSON function takes a string as input and returns a JSON-compatible VARIANT. The TO_JSON function takes a JSON-compatible VARIANT and returns a string. For syntax compatibility with other databases, Snowflake supports specifying non-default values for the constraint properties. However, if you specify ENABLE or VALIDATE (the non-default values for these properties) when creating a new constraint, the constraint is not created. This does not apply to RELY. Specifying RELY does result in the ...

However, the functions are not perfectly reciprocal because: Empty strings, and strings with only whitespace, are not handled reciprocally. For example, the return value of PARSE_JSON('') is NULL, but the return value of TO_JSON(NULL) is not ''. The order of the key-value pairs in the string produced by TO_JSON is not predictable.. The string … Wildcards in pattern include newline characters ( n) in subject as matches. LIKE pattern matching covers the entire string. To match a sequence anywhere within a string, start and end the pattern with %. NULL does not match NULL.

Please note that the null value is a string instead of a json native null value like: ["Simon", "Sarah", null] This can cause problems in downstream systems working with that array, because the semantics of a string and of an actual null are very different. Since we rely on the existing of "real" null values we had to come up with another solution.Note that Snowflake converts all instances of the value to NULL, regardless of the data type. For example, if 2 is specified as a value, all instances of 2 as either a string or number are converted.
