> When multiple macros are used in one column, results of the later ones are
> over written by that of the first.
> For example:
> Suppose we have created a table called macro_test with single column x in
> STRING type, and with data as:
> "a"
> "bb"
> "ccc"
> We also create three macros:
> {code}
> CREATE TEMPORARY MACRO STRING_LEN(x string) length(x);
> CREATE TEMPORARY MACRO STRING_LEN_PLUS_ONE(x string) length(x)+1;
> CREATE TEMPORARY MACRO STRING_LEN_PLUS_TWO(x string) length(x)+2;
> {code}
> When we ran the following query,
> {code}
> SELECT
> CONCAT(STRING_LEN(x), ":", STRING_LEN_PLUS_ONE(x), ":",
> STRING_LEN_PLUS_TWO(x)) a
> FROM macro_test
> SORT BY a DESC;
> {code}
> We get result:
> 3:3:3
> 2:2:2
> 1:1:1
> instead of expected:
> 3:4:5
> 2:3:4
> 1:2:3
> Currently we are using Hive 1.2.1, and have applied both HIVE-11432 and
> HIVE-12277 patches.
