In this PR, we introduce TOKENIZE function for inverted index, it is used as following:
```
SELECT TOKENIZE('I love my country', 'english');
```
It has two arguments, first is text which has to be tokenized, the second is parser type which can be **english**, **chinese** or **unicode**.
It also can be used with existing table, like this:
```
mysql> SELECT TOKENIZE(c,"chinese") FROM chinese_analyzer_test;
+---------------------------------------+
| tokenize(`c`, 'chinese') |
+---------------------------------------+
| ["来到", "北京", "清华大学"] |
| ["我爱你", "中国"] |
| ["人民", "得到", "更", "实惠"] |
+---------------------------------------+
```
mysql >select sec_to_time(time_to_sec(cast('16:32:18' as time)));
+----------------------------------------------------+
| sec_to_time(time_to_sec(CAST('16:32:18' AS TIME))) |
+----------------------------------------------------+
| 16:32:18 |
+----------------------------------------------------+
1 row in set (0.53 sec)
mysql [test]>select sec_to_time(59538);
+--------------------+
| sec_to_time(59538) |
+--------------------+
| 16:32:18 |
+--------------------+
1 row in set (0.03 sec)
This commit support a function allows return a field column in named struct column.
Since the function can return any type, this commit also supports ANY_STRUCT_TYPE
and ANY_ELEMENT_TYPE.
In this PR, I have refactored the initialization of the FunctionSet. Previously, all the functions were in one large method which led to the generation of Java code that was too long. This posed a problem for the compiler, as the length of the method exceeded the limit imposed by the Java compiler.
To resolve this issue and improve the readability and manageability of our code, I have categorized these functions by type, and created dedicated initialization methods for each type. As such, our code is now not only more readable and understandable, but also each method is of a length that is acceptable to the compiler and can be compiled successfully.
Moreover, this change makes it easier for us to add new functions as we can directly locate the right category and add new functions there.
This is a significant change aimed at enhancing the maintainability and scalability of our code, while ensuring that our code can be successfully compiled.
To be more compatible with MySQL, rename JSONB type name and function name to JSON.
The old JSONB type name and jsonb_xx function can still be used for backward compatibility.
There is a function jsonb_extract remained since json_extract is used by json string function and more work need to change it. It will be changed further.
