注意

Please note, in Proton 1.3.27 or the earlier versions, SQL functions were case-sensitive and always in lower-case. Since 1.3.28, function names are case-insensitive. For example count, COUNT and Count work in the same way. SQL Keywords such as SELECT or FROM are case-insensitive too. In the rest of the documentation, we use function names in lower case for demonstration. 自 1.3.28 起，函数名不区分大小写。例如 count、 COUNT 和 Count 的工作方式相同。像 SELECT 或 FROM 这样的 SQL 关键字也不区分大小写。在文档的其余部分中，我们使用小写的函数名称进行演示。
