UNPIVOT. Rotates a table by transforming columns into rows. UNPIVOT is a relational operator that accepts two columns (from a table or subquery), along with a list of columns, and generates a row for each column specified in the list. In a query, it is specified in the FROM clause after the table name or subquery.Create a stored procedure. This inserts a row into an existing table named stproc_test_table1 and returns the value “Succeeded.”. The returned value is not particularly useful from a SQL perspective, but it allows you to return status information (e.g. “Succeeded.” or “Failed.”) to the user.A window function is any function that operates over a window of rows. A window function is generally passed two parameters: A row. More precisely, a window function is passed 0 or more expressions. In almost all cases, at least one of those expressions references a column in that row. (Most window functions require at least one column or ...I have a field/column 'reactions' in a Snowflake table 'tbl'. The table contains several columns of data and many records.

The function returns an ARRAY containing the distinct values in the specified column. The values in the ARRAY are in no particular order, and the order is not deterministic. The function ignores NULL values in column. If column contains only NULL values or the table containing column is empty, the function returns an empty ARRAY.

Specifies one or more tables to use for selecting rows to update or for setting new values. Note that repeating the target table results in a self-join. WHERE condition. Expression that specifies the rows in the target table to update. Default: No value (all rows of the target table are updated) Usage Notes¶

The source array. A (zero-based) position in the source array. The new element is inserted at this position. The original element from this position (if any) and all subsequent elements (if any) are shifted by one position to the right in the resulting array (i.e. inserting at position 0 has the same effect as using ARRAY_PREPEND ).So FLATTEN on your JSON would give you access to the three sub objects of the array, but you are wanting to access two sub objects by name, if you have sets of there values/objects in your data, and they are all related via set_timestamp_micros, you could PIVOT after FLATTEN or you could MAX likeJul 8, 2019 ... gardner (Snowflake)​ This does work although it's a bit dirtier.

Semi-structured Data Files and Columnarization. When semi-structured data is inserted into a VARIANT column, Snowflake uses certain rules to extract as much of the data as possible to a columnar form. The rest of the data is stored as a single column in a parsed semi-structured structure. By default, Snowflake extracts a maximum of 200 elements ... The function returns an ARRAY containing the distinct values in the specified column. The values in the ARRAY are in no particular order, and the order is not deterministic.

Following is the list of Snowflake array functions with brief descriptions: Array Functions. Description. ARRAY_AGG. Function returns the input values, pivoted into an ARRAY. ARRAY_APPEND. This function returns an array containing all elements from the source array as well as the new element. ARRAY_CAT.

array. The source array. new_element. The element to be appended. The type of the element depends on the type of the array: If array is a semi-structured ARRAY, the element may be of almost any data type. The data type does not need to match the data type(s) of the existing elements in the array.So FLATTEN on your JSON would give you access to the three sub objects of the array, but you are wanting to access two sub objects by name, if you have sets of there values/objects in your data, and they are all related via set_timestamp_micros, you could PIVOT after FLATTEN or you could MAX likeExtracts a value from an ARRAY or an OBJECT (or a VARIANT that contains an ARRAY or OBJECT).

Snowflake Split String. In many relational databases such as Netezza, PostgreSQL, etc, you can use array functions to extract records from split string result.. But, Snowflake supports many useful split functions that you can use to extract the required field from a delimited strings.

The data type of the returned value is ARRAY. Usage Notes¶ The data types of the inputs may vary. If the function is called with N arguments, the size of the resulting array will be N. In many contexts, you can use an ARRAY constant (also called an ARRAY literal) instead of the ARRAY_CONSTRUCT function. Examples¶
