In particular, HASH_AGG is “stable” in the sense that any Snowflake’s native handling of JSON in both READ and WRITE operations is by far and away my favourite feature. g. e. The contrast in output between this example and the following example shows that ARRAY_AGG () pivots the data. My table Note In the definition of a standard Snowflake table (non-Iceberg) column, you can’t specify GEOGRAPHY as the type of the value corresponding to the OBJECT key. Reference Function and stored procedure reference Aggregate Aggregate functions Aggregate functions operate on values across rows to perform mathematical calculations such as sum, average, Note Y stands for yes (supports distributed implementation), N stands for no (API simply errors out), and P stands for partial (meaning some parameters may not be supported yet). This example shows non-pivoted output from a query that does not use ARRAY_AGG (). Snowflake Array Functions, Syntax, Examples, Snowflake array methods, array data type, array distinct values, array to row, array to string Object aggregation in Snowflake is a tool for processing semi-structured data, and it’s default use isn’t data pivoting.
