[1] A known issue in Snowflake displays FLOAT, FLOAT4, FLOAT8, REAL, DOUBLE, and DOUBLE PRECISION as FLOAT even though they are stored as DOUBLE.All the regular expression functions support Unicode. A single Unicode character always counts as one character (i.e. the POSIX meta-character . matches exactly one Unicode character), regardless of the byte-length of the corresponding binary representation of that character. Also, for functions that take or return subject offsets, a single ...1. 16MB limit is related to the internal representation of the large objects, so there is no workaround for now. In future, I expect that Snowflake will support larger objects. I do not know why you need to execute a SELECT inside the stored procedure, but maybe Snowflake Scripting can help you to return the JSON array as multiple rows:

The semi-structured data types include: VARIANT: can store values of any other types, including OBJECT and ARRAY, and has a maximum length of 16 MB. @ResidentSleeper sqlalchemy.types.ARRAY is not working if you have a variable length list elements in a pd dataframe column. assume first element of this column is ['a', 'b', 'c'] and len = 3, and second element is ['a'] whose len =1, then it will cause Inconsistent number of values in the VALUES clause expecting 3 but got 1 –In Snowflake, arrays are multi-sets, not sets. In other words, arrays can contain multiple copies of the same value. ARRAY_EXCEPT compares arrays by using multi-set semantics (sometimes called “bag semantics”). If source_array includes multiple copies of a value, the function only removes the number of copies of that value that are ...When copying data from files in a table location, the FROM clause can be omitted because Snowflake automatically checks for files in the table’s location.

Edit: It seems like your issue is that your column is a string. There's a few ways to work around this. Change your column's datatype to a variant or array. Parse your column before using array functions array_size (TRY_PARSE_JSON (column_name)) != 0. Compare to a string instead column_name is not null and column_name != ' []'.

When copying data from files in a table location, the FROM clause can be omitted because Snowflake automatically checks for files in the table’s location.
