### What changes were proposed in this pull request? `UnaryPositive` only accepts numeric and interval as we defined, but what we do for this in `AstBuider.visitArithmeticUnary` is just bypassing it. This should not be omitted for the type checking requirement. ### Why are the changes needed? bug fix, you can find a pre-discussion here https://github.com/apache/spark/pull/26578#discussion_r347350398 ### Does this PR introduce any user-facing change? yes, +non-numeric-or-interval is now invalid. ``` -- !query 14 select +date '1900-01-01' -- !query 14 schema struct<DATE '1900-01-01':date> -- !query 14 output 1900-01-01 -- !query 15 select +timestamp '1900-01-01' -- !query 15 schema struct<TIMESTAMP '1900-01-01 00:00:00':timestamp> -- !query 15 output 1900-01-01 00:00:00 -- !query 16 select +map(1, 2) -- !query 16 schema struct<map(1, 2):map<int,int>> -- !query 16 output {1:2} -- !query 17 select +array(1,2) -- !query 17 schema struct<array(1, 2):array<int>> -- !query 17 output [1,2] -- !query 18 select -'1' -- !query 18 schema struct<(- CAST(1 AS DOUBLE)):double> -- !query 18 output -1.0 -- !query 19 select -X'1' -- !query 19 schema struct<> -- !query 19 output org.apache.spark.sql.AnalysisException cannot resolve '(- X'01')' due to data type mismatch: argument 1 requires (numeric or interval) type, however, 'X'01'' is of binary type.; line 1 pos 7 -- !query 20 select +X'1' -- !query 20 schema struct<X'01':binary> -- !query 20 output ``` ### How was this patch tested? add ut check Closes #26716 from yaooqinn/SPARK-30083.
