sqlite3.OperationalError：“ [Total Babies]”附近：语法错误

Question

我尝试使用python找出某年的婴儿出生方式，但收到以下错误 sqlite3.OperationalError：“ [Total Babies]”附近：语法错误

下面是代码

   query = """
            SELECT sum(b[Total Babies]) AS TotalBoys, sum(g[Total Babies]) AS TotalGirls 
            FROM BOYS b JOIN GIRLS g ON b.RANK = g.RANK
        """
c.execute(query)
res = c.fetchone()[0]
num_boys = int(res["TotalBoys"])
num_girls = int(res["TotalGirls"])
num_babies = num_boys + num_girls

Answer 1

我认为您需要在表名和列名之间使用句点.，因此请尝试使用：-

query = """
        SELECT sum(b.[Total Babies]) AS TotalBoys, sum(g.[Total Babies]) AS TotalGirls 
        FROM BOYS b JOIN GIRLS g ON b.RANK = g.RANK
    """
