Snowflake recommends avoiding NOT NULL for SQL UDFs unless the code in the function is written to ensure that NULL values are never returned. CALLED ON NULL INPUT or { RETURNS NULL ON NULL INPUT | STRICT } Specifies the behavior of the UDF when called with null inputs. In contrast to ...
The simple expression can include a SQL UDF (user-defined function) if the UDF is not a secure UDF. Note If a default expression refers to a SQL UDF, then the function is replaced by its definition at table creation time. If the user-defined function is redefined in the future, this ...

The first step is to create a memoizable User-Defined Function (UDF), UDF_REGIONS(), that will combine all values for a given key from the ENT_REGION table into an array. Then we can create a RAP, RAP_REGION_USER, that checks to see if the input region ID is in the array ...
The number of external functions in the SQL statement. The number of rows per batch sent to each remote service. The number of retries due to transient errors (e.g. because a response was not received within the expected time). Query retry columns A query might need to be retried one or...
For more details about UDF naming, see User-defined functions overview. Grant usage privilege on a stored procedure in the mydb.myschema schema to the mydb.dr1 database role: GRANT USAGE ON PROCEDURE mydb.myschema.myprocedure(number) TO DATABASE ROLE mydb.dr1; Note that stored ...
These types of dependencies are specified by the partial/full qualified name of the referenced object in the referencing object's definition where the definition is a SQL expression. Objects such as views, policies, functions, and procedures are examples that fall into this category. ...
(UDF). The UDF may not contain its code, instead, it may call code that is stored and executed outside of the network-based database system102. In this regard, the external function518allows for API integration706and invokes external APIs within one or more SQL queries to obtain a ...
