我是Python的新手,所以也许我犯了一个新手的错误。但这似乎不是我在这种情况下应该得到的那种错误。
在一个非常简单的SELECT语句中,我得到一个“列表索引超出范围”错误。
sql = """
begin tran
-- Several update statements are in this block.
commit tran"""
sql = sql.format(tablename=self.tablename, **self.mappings)
#print(sql)
self.cursor.execute(sql, (self.catalog_id,self.catalog_id,self.catalog_id,))
self.cursor.execute("SELECT CaptionText, DisplayOrder FROM dbo.SizeOrder where CaptionText is not NULL and len(CaptionText)>0") #This is the line that breaks!
size_order = {row[0].lower(): row[1] for row in self.cursor}
这是最后一行的下一个突破。它没有做任何有趣的格式化。我没有在此问题查询中进行任何替换。直接针对数据库运行时,它会返回超过300条记录。
跟踪输出肯定涉及该行代码。我真的怀疑下一行b / c它涉及索引。但执行后的回报没有任何帮助。

我可能做错了什么?谢谢!
