Snowflake also supports the FLATTEN command, which produces a lateral view of an OBJECT or ARRAY within a VARIANT column. The VARIANT data type imposes a 16 MB size limit on individual rows, and Snowflake recommends using this data type when you are not sure what operations you intend to p...

When setting a column toNOTNULL, if the column contains NULL values, an error is returned and no changes are applied to the column. Columns that use semi-structured data types (ARRAY, OBJECT, and VARIANT) cannot be set toNOTNULL, except when the table is empty. Setting these columns to...
Target Value:payload You have now configured the Snowflake connector to retrieve the list of shirt prices and store it in the variable called shirt_prices_raw. Next we need to flatten the array that was returned by the select function to correctly map the key:value pairs as “shirt_size:sh...
Using a residual predicate operation on the Clustered Index Scan Operator, it implicitly converts each LastName value to NVARCHAR(50), the Unicode value, before comparing it with the query parameter value N”Goldberg”. Interestingly enough, if we set up our test DB to use Windows-based ...

In the previous example of the searchable value of “solution,” the database system constructs the fingerprints for “solut” (e.g., where N=5) and “soluti” (e.g., where N=6) in such a way that the fingerprint of “soluti” contains a superset of the bits in the fingerprint ...
