Rules and Guidelines for Complex Data Types

Rules and Guidelines for Complex Data Types

Consider the following rules and guidelines when you work with complex data types:
  • A nested data type can contain up to 10 levels of nesting.
  • A nested map can contain up to three levels of nesting of map data types.
  • An array data type cannot directly contain an element of type array. Use multidimensional arrays to create a nested array. For example, an array with two dimensions is an array of arrays.
  • A multidimensional array can contain up to five levels of nesting. The array dimension determines the levels of nesting.
  • Each array in a multidimensional array must have elements of the same data type.
