SQL Server分组字段执行报错及结果不符问题咨询

It sounds like you're stuck with two frustrating problems right now: a runtime error popping up when your cut-off time logic is active, plus unexpected results after tweaking the recordtime field. To help you nail this down effectively, I’ll need a few more key details from you:

• Share your full SQL query, especially the section where you built out the cut-off time condition. Syntax missteps, incorrect function usage, or logical gaps here are almost certainly the root of your error.
• Include the exact error message you’re getting. Is it a syntax error? A data type mismatch (like trying to compare a timestamp to a numeric value)? Or something else entirely? Error messages are critical clues for pinpointing issues fast.
• Clearly outline your desired outcome. For example: "When cut-off time isn’t 0, I want to return only records where recordtime is later than the cut-off value; when it’s 0, return all records without filters."
• Explain what unexpected results you got after modifying recordtime—were you missing critical records, pulling in unwanted ones, or getting a completely different dataset than you expected?

Once you share these details, we can dig into the logic, fix the error, and adjust your query to spit out exactly the results you’re aiming for.
