A JSON document is stored in the source_colum of type VARIANT. The document has an array called elements. The array contains the name key that has a string value How can a Snowflake user extract the name from the first element?
In Snowflake, when dealing with semi-structured data such as a JSON document stored in aVARIANTcolumn, the proper syntax to extract a value is to use the column name followed by the path to the specific element. Since arrays in JSON are zero-indexed, the first element is referenced with[0]. Therefore, to extract thenamefrom the first element of theelementsarray, the correct syntax isSource_column:elements[0].name.
