如何知道某段时间内的所有值是否都大于10？

SELECT COUNT(*) = COUNT(value) AND MIN(value) > 10 
FROM your_table 
WHERE timestamp BETWEEN 'start_time' AND 'end_time';

def all_values_greater_than_10(data, start_time, end_time):
    for entry in data:
        if start_time <= entry['timestamp'] <= end_time and entry['value'] <= 10:
            return False
    return True

# 假设data是一个包含时间戳和值的列表
data = [
    {'timestamp': '2023-01-01 10:00:00', 'value': 11},
    {'timestamp': '2023-01-01 10:01:00', 'value': 12},
    # ...
]

start_time = '2023-01-01 10:00:00'
end_time = '2023-01-01 10:02:00'

result = all_values_greater_than_10(data, start_time, end_time)
print(result)  # 输出：True 或 False

import pandas as pd

# 假设df是一个包含时间戳和值的DataFrame
df = pd.DataFrame({
    'timestamp': ['2023-01-01 10:00:00', '2023-01-01 10:01:00', ...],
    'value': [11, 12, ...]
})

start_time = '2023-01-01 10:00:00'
end_time = '2023-01-01 10:02:00'

mask = (df['timestamp'] >= start_time) & (df['timestamp'] <= end_time) & (df['value'] > 10)
result = df[mask].empty
print(result)  # 输出：True 或 False
