- **Version 1.0 has changed the SQL syntax conventions (please refer to the syntax conventions section of the user manual)**.
- In order to ensure the stability of UDF-related APIs, in version 1.0, UDF-related APIs are seperated into an independent module and no longer depend on the tsfile package. The implemented UDFs need to rewrite the code, replace `TsDataType` with `Type`, and replace `org .apache.iotdb.tsfile.utils.Binary` with `org.apache.iotdb.udf.api.type.Binary`, then redo the packaging and loading process.

For example, in the statement "select 123 + \`123\` from root.sg", the former 123 represents a constant, and the latter \`123\` will be spliced with root.sg, indicating the path root.sg.\`123\`.**
