我有一个 pandas 数据框，其中有一列 ID。我需要运行另一个 sql 查询，其“WHERE”子句由上述列中的所有 ID 指定。
Ex:
df1 = DataFrame({'IDs' : [1,2,3,4,5,6]})
query = """ Select id, SUM(revenue) AS revenue WHERE id IN (***want df1['IDs'] here***) Group by 1"""
df2 = my_database.select_dataframe(query)
将系列转换为字符串
str = ','.join([str(x) for x in df1['IDs'].tolist()])
str
'1,2,3,4,5,6'
然后将其插入查询字符串 -
qry = "Select id, SUM(revenue) AS revenue WHERE id IN (%s) Group by 1" % str
qry
'Select id, SUM(revenue) AS revenue WHERE id IN (1,2,3,4,5,6) Group by 1'
