Snowflake maintains statistics on tables and views, and this optimization allows simple queries to run faster. When a row access policy is set on a table or view and the COUNT function is used in a query, Snowflake must scan each row and determine whether the user is allowed to view the row. Constraints other than NOT NULL are created as disabled. Snowflake enforces only NOT NULL. You can create NOT NULL constraint while creating tables in the cloud database. A Snowflake table can have multiple NOT NULL columns. Snowflake NOT NULL Constraint Syntax. There are many methods that you can use to add NOT NULL on Snowflake table.

Boolean columns can be used in expressions (e.g. SELECT list), as well as predicates (e.g. WHERE clause). The BOOLEAN data type enables support for Ternary Logic.The join operation specifies (explicitly or implicitly) how to relate rows in one table to the corresponding rows in the other table, typically by referencing the common column (s), such as project ID.

A special version of the TO_DATE function that performs the same operation (i.e. converts an input expression to a date), but with error-handling support (i.e. if the conversion cannot be performed, it returns a NULL value instead of raising an error). For more information, see Error-handling Conversion Functions.IS [ NOT ] NULL¶. Legt fest, ob ein Ausdruck NULL oder nicht NULL ist.Snowflake does not currently support explicitly-typed objects. In a key-value pair, the key should not be an empty string, and neither the key nor the value should be NULL. The maximum length of an OBJECT is 16 MB. An OBJECT can contain semi-structured data. An OBJECT can be used to create hierarchical data structures.The above df was created with column name “name” while the returned column name after collect() was called became “NAME”. It’s because the column is regarded as ignore-case so the Snowflake database returns the upper case. To create a Column object that represents a constant value, use snowflake.snowpark.functions.lit():

IS_NULL_VALUE is another Snowflake-specific function that does not exist in SQL. In semi-structured data, Snowflake supports two types of NULL values: SQL NULL – the value is missing or unknown; VARIANT or JSON NULL – To distinguish JSON null values from SQL NULLs in the VARIANT string, they are stored as a "null" string. If one of the arguments is a number, the function coerces non-numeric string arguments (e.g. 'a string') and string arguments that are not constants to the type NUMBER (18,5). For numeric string arguments that are not constants, if NUMBER (18,5) is not sufficient to represent the numeric value, you should cast the argument to a type that can ...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. For example: NULL_IF = ('\N', 'NULL', 'NUL', '') Note that this option can include empty strings.
