1.
In the "explain" result of SQL, the table name in `ScanNode` should be full qualified with dbname.
And for olap scan node, the selected index name should not be "null".
2.
Remove `tpch_sf1_p1/tpch_sf1/nereids/` in regression test, it will be fixed later.
Previous logic of reverse function might not be strong enough to handle illegal character. For example, one one byte size character would be mistaken as one utf-8 character which occupies more than one byte space. And unfortunately exceeding the buffer space during future process.
1. this pr is used to fix the be core dump when select the invalid array.
2. before the change, we run "select array_intersect([1, 2, 3, 1, 2, 3], '1[3, 2, 5]');" will cause be core dump.
MySQL [example_db]> select array_intersect([1, 2, 3, 1, 2, 3], '1[3, 2, 5]');
ERROR 1105 (HY000): RpcException, msg: io.grpc.StatusRuntimeException: UNAVAILABLE: Network closed for unknown reason
3. after the change, we run "select array_intersect([1, 2, 3, 1, 2, 3], '1[3, 2, 5]');" will get error message.
MySQL [example_db]> select array_intersect([1, 2, 3, 1, 2, 3], '1[3, 2, 5]');
errCode = 2, detailMessage = No matching function with signature: array_intersect(array<tinyint(4)>, varchar(-1))"

Support delete from partitioned table without partition specified in [DELETE] stmt.
## Usage
If it is a partitioned table, you can specify a partition.
If not specified, Doris will infer partition from the given conditions.
In two cases, Doris cannot infer the partition from conditions:
1) the conditions do not contain partition columns;
2) The operator of the partition column is `not in`.
When a partition table does not specify the partition,
or the partition cannot be inferred from the conditions,
the session variable `delete_without_partition` needs to be `true`
to make delete statement be applied to all partitions.
## Test case
Test case is added in `regression-test/suites/delete_p0/test_delete_from_partition.groovy`,
user can delete from partitioned table without partition specified now.
When running regression test, we always found that the query return empty result after loading finished,
even if we call "sync" before the query.
This is because for `stream load`, the load task result will be returned immediately after the txn's status changed to VISIBLE,
but before writing the edit log.
So if we do the query right after we got the load task result, it is possible that we can not see the latest loaded data.
Same issue with `insert` operation
Issue Number: close#12574
This pr adds `NewJsonReader` which implements GenericReader interface to support read json format file.
TODO:
1. modify `_scann_eof` later.
2. Rename `NewJsonReader` to `JsonReader` when `JsonReader` is deleted.
1. add "sync" to avoid some potential meta sync problem when running regression test on multi-node cluster
2. Use /tmp dir as dest dir of outfile test, to avoid "No such file or directory" error.
From now, we don't support type derivation for array function's arguments.
So that the cases below will return wrong values or even cause be core.
mysql> select array_union([1],[10000000]);
+----------------------------------------+
| array_union(ARRAY(1), ARRAY(10000000)) |
+----------------------------------------+
| [1, -128] |
+----------------------------------------+

mysql> select array_union([NULL],[1]);

This commit make a small fix to derivate the argument types of the array function
1、 For null type in arguments, cast the null type to boolean type, because null type should not be seen in be.
2、For different types in arguments, cast all arguments type to their compatible type.
