Conversely, JSON permits null values while property lists do not support explicit nulls. Some SQL products do not index keys containing NULLs. SQL defines two functions to explicitly handle Nulls&colon; codice 68 and codice 12. The SQL standard does not explicitly define a default sort order for Nulls. Determining the first nulls of the radiation pattern gives the beamwidth formula 18. Similarly, Nulls are often confused with empty strings. The SQL standard's core functionality does not explicitly define a default sort order for Nulls. Critics assert that this inconsistency deprives SQL of intuitive semantics in its treatment of NULLs. A string is any arbitrary sequence of bytes (including nulls). Other SQL operations, clauses, and keywords use "not distinct" in their treatment of Nulls. The radiation pattern of a small loop antenna has two sharp nulls in opposite directions. A main lobe is produced together with nulls and sidelobes. All of the nulls sensed this danger and covered her completely. After receiving them for 125us, it switches to sending NULLs. They are also able to manufacture android-like beings called "nulls" from leftover genetic material.
