Both For information about coercion, see Data type conversion. Learn simple and advanced SQL examples, performance tips, and best practices for optimizing ELT Suppose this Array is an array of Objects and each object has attributes labeled 'a' through 'f'. If array is a structured array, value_expr must evaluate to a type that is comparable to the type of the array. This article will teach If array is a semi-structured array, value_expr must evaluate to a VARIANT.
