TDengine ERROR (0x2600): sql

Current Behavior/问题描述

修改了apijson.SQL 265行，给count加上了``; return function(fun, column) + AS + "`" + fun + "` ";

这样会对其他方面有影响吗？

正常查询 TDengine 数据

Research direction
Investigate the fix suggested by the reporter: adding backticks around the count function in apijson.SQL line 265. Determine whether this change would break queries for other supported databases (e.g., MySQL, PostgreSQL). Also verify if TDengine requires backticks for count or if there is a standard way to escape function names. Look for any existing tests that cover SQL generation and consider adding a test for TDengine count queries.
