we are hesitant to blow it out on ingestion because it will cause an already humongous table to be billions more, yet performance on flattening is pretty bad involving these large json tables. even on using an XL size warehouse it was much slower than Big Query doing the same thing. There are no multidimensional variables in Snowflake (assuming that is what you mean by "table variable") but since you can put JSON into a string variable, you can use that for almost anything. Have a look at the documentation of SQL Variables. If you want to use SQL Variables to name tables, try: SET my_table = 'information_schema.tables';

Redirecting to - Snowflake Inc. ... Redirecting... The function itself takes no arguments because it returns the rank (relative position) of the current row within the window, which is ordered by <expr2>. The ordering of the window determines the rank, so there is no need to pass an additional parameter to the RANK function.

Jan 08, 2020 · Snowflake STRTOK Function. The STRTOK Function tokenizes a given string and returns the requested part. If the part does not exist, then function will return NULL. If any parameter is NULL, then NULL is returned. Following is the STRTOK function syntax. STRTOK(<string> [,<delimiter>] [,<partNr>]) where, the string is the input string. High performance and unlimited concurrency. Snowflake’s multi-cluster, shared data architecture spins up additional compute clusters to support a near-unlimited number of concurrent users on shared tables without contention for resources. SHOW COLUMNS¶. Lists the columns in the tables or views for which you have access privileges. This command can be used to list the columns for a specified table/view/schema/database (or the current schema/database for the session), or your entire account.

For object_type, TABLE and VIEW are interchangeable. If a TABLE object type is specified, and the object specified by name is a view, the function returns the DDL for the view and vice-versa. If object_type is FUNCTION (i.e. UDF) and the UDF has arguments, you must include the argument data types as part of the function name, in the form of ' function_name ( [ arg_data_type [ , ... These functions are used with semi-structured data (JSON, Avro, XML), typically stored in Snowflake in VARIANT, OBJECT, or ARRAY columns. String & Binary Functions This family of functions perform operations on a string input value, or binary input value (for certain functions), and return a string or numeric value.

We had to use the TABLE function with our table UDF and the OVER clause for defining the input rows. The result of our query is the following: UDAFs with window function in Snowflake. While table UDFs cannot be natively utilized by window functions, there are some workarounds we will show you. Only the user who ran the original query can use the RESULT_SCAN function to post-process the results of that query.
