LISTAGG Syntax in Snowflake
LISTAGG in Snowflake concatenates grouped column values into a single, delimited string. Key syntax differences:
Delimiter: Required between values.
WITHIN GROUP (ORDER BY ...): Specify sort order inside groups.
ON OVERFLOW: Control overflow behavior (Snowflake supports 'TRUNCATE WITH COUNT').
