starting with `ST_` in the function. For details, please refer to the section
on SQL functions in the official documentation.
2. The `UDF` and `UDAF` of the original row storage execution engine are not
supported.
-3. It is not supported to rewrite the between statement into a compound
judgment statement, which will result in the following error: `BetweenPredicate
needs to be rewritten into a CompoundPredicate`.
-4. The `TupleIsNull` function is not supported, which may cause partial outer
joins and expressions with non-Nullable functions to obtain the required NULL
value.
-5. The maximum length of `string/text` type is 1MB instead of the default 2GB.
That is, when the vectorization engine is turned on, it is impossible to query
or import strings larger than 1MB. However, if you turn off the vectorization
engine, you can still query and import normally.
-6. The export method of `select ... into outfile` is not supported.
-7. Lateral view is not supported.

1. 不支持`地理位置函数` ，包含了函数中所有以`ST_`开头的函数。具体请参考官方文档SQL函数的部分。
2. 不支持原有行存执行引擎的`UDF`与`UDAF`。
-3. 不支持将between语句改写为复合判断语句，会导致以下报错：`BetweenPredicate needs to be rewritten into
a CompoundPredicate`。
-4. 不支持`TupleIsNull`函数，可能会导致部分外连接并带有非Nullable函数计算的表达式无法得到所需的NULL值。
