1. In apache#49036, we only support hive serde dialect in BE side. But some constant expr will be evaluated and output in FE side, need to support it too. 2. Refactor the method of getting string format value for all type of literals in FE side. There are 2 kind of string format value for literal. One is for Query, the other is for Stream Load. Here is some difference: - NullLiteral For query, it should be `null`. For load, it should be `\N`. - StructLiteral For query, it should be `{"k1":"v1", "k2":null, "k3":"", "k4":"a"}`. For load, it should be `{"v1", null, "", "a"}` So we need 2 different methods to distinguish them: `getStringValueForQuery` and `getStringValueForStreamLoad`. And I removed or renamed some old and messy methods. **Exmples** - `Doris/Hive/Presto` means when setting `serde_dialect` to these types, the format of query result for different column types. - `Stream Load ` means what format should be like in csv format when loading to the table | Type | Doris | Hive | Presto | Stream Load | Comment | | --- | --- | --- | --- | --- | --- | | Bool | `1`, `0` | `1`, `0` | `1`, `0` | `1|0`, `true|false` || | Integer | `1`, `1000` | `1`, `1000` | `1`, `1000` | `1|1000` | | | Float/Decimal | `1.2`, `3.00` | `1.2`, `3.00` | `1.2`, `3.00` | `1.2|3.00` | | | Date/Datetime | `2025-01-01`， `2025-01-01 10:11:11` | `2025-01-01`， `2025-01-01 10:11:11` | `2025-01-01`， `2025-01-01 10:11:11` | `2025-01-01|2025-01-01 10:11:11` | | | String | `abc`, `中国` | `abc`, `中国` | `abc`, `中国` | `abc,中国` | | | Null | `null` | `null` | `NULL` | `\N` || | Array<bool> | `[1, 0]` | `[true,false]` | `[1, 0]` | `[1, 0]`, `[true, false]` || | Array<int> | `[1, 1000]` | `[1,1000]` | `[1, 1000]` | `[1, 1000]` || | Array<string> | `["abc", "中国"]` | `["abc","中国"]` | `["abc", "中国"]` | `["abc", "中国"]` | | | Array<date/datetime> | `["2025-01-01", "2025-01-01 10:11:11"]` | `["2025-01-01","2025-01-01 10:11:11"]` | `["2025-01-01", "2025-01-01 10:11:11"]` | `["2025-01-01", "2025-01-01 10:11:11"]` || | Array<null> | `[null]` | `[null]` | `[NULL]` | `[null]` | | | Map<int, string> | `{1:"abc", 2:"中国"}` |`{1:"abc",2:"中国"}` |`{1=abc, 2=中国}` | `{1:"abc", 2:"中国"}` | | | Map<string, date/datetime> | `{"k1":"2022-10-01", "k2":"2022-10-01 10:10:10"}` | `{"k1":"2022-10-01","k2":"2022-10-01 10:10:10"}` | `{k1=2022-10-01, k2=2022-10-01 10:10:10}` | `{"k1":"2022-10-01", "k2":"2022-10-01 10:10:10"}` | | | Map<int, null> | `{1:null, 2:null}` | `{1:null,2:null}` | `{1=NULL, 2=NULL}` | `{1:null, 2:null}` | | | Struct<> | Same as map | Same as map | Same as map | Same as map | | 3.
