As of Hive 0.12.0. Bug fixes: - Prior to Hive 1.3.0 and 2.0.0 when a HiveQL macro was used more than once while processing the same row, Hive returned the same result for all invocations even though the arguments were different. (See HIVE-11432.)
- Prior to Hive 1.3.0 and 2.0.0 when multiple macros were used while processing the same row, an ORDER BY clause could give wrong results. (See HIVE-12277.)
- Prior to Hive 2.1.0 when multiple macros were used
in one column- while processing the same row, results of the later
ones - macros were overwritten by that of the first. (See HIVE-13372.)

Hive 0.12.0 introduced macros to HiveQL, prior to which they could only be created in Java.
