我使用table1表格中的table2显示了两个表格（即connection.cursor和SOURCE）
ISSUE：
现在我必须减去table1(fields)-table2(fields)并将输出显示为table3。
方案：
IN views.py
cursor1.execute('''select dummy as LCR_CUSTOMER_TYPE,CUR AS CURRENCY,'$'+CONVERT(VARCHAR(20), CONVERT(MONEY, sum(LCR_NONOP_INS))) as LCR_NONOP_INS, '$'+CONVERT(VARCHAR(20), CONVERT(MONEY, sum(LCR_OP_INS))) as LCR_OP_INS, '$'+CONVERT(VARCHAR(20), CONVERT(MONEY, sum(LCR_NONOP_UNINS)))as LCR_NONOP_UNINS, '$'+CONVERT(VARCHAR(20), CONVERT(MONEY,sum(LCR_OP_UNINS)))as LCR_OP_UNINS from (select *,(case when LCR_CUSTOMER_TYPE='Corporate' then 'Non-Credit Financial Entities'else LCR_CUSTOMER_TYPE end) as dummy from DDA_BASED_S9_20150930) a group by CUR,dummy''') cursor.execute('''select AFTERMEMO,CUR AS CURRENCY,'$'+CONVERT(VARCHAR(20), CONVERT(MONEY, sum(LCR_NONOP_INS))) as LCR_NONOP_INS,'$'+CONVERT(VARCHAR(20), CONVERT(MONEY, sum(LCR_OP_INS))) as LCR_OP_INS, $'+CONVERT(VARCHAR(20), CONVERT(MONEY, sum(LCR_NONOP_UNINS))) as LCR_NONOP_UNINS, '$'+CONVERT(VARCHAR(20), CONVERT(MONEY, sum(LCR_OP_UNINS))) as LCR_OP_UNINS from (select *,(case when SIC_CODE = 7215 and LCR_CUSTOMER_TYPE = 'Non-Credit Financial Entities' then 'NonFinancialCorp' when LCR_CUSTOMER_TYPE = 'Corporate' then 'Non-Credit Financial Entities' else LCR_CUSTOMER_TYPE end) as AFTERMEMO from DDA_BASED_S9_20150930) a group by CUR,AFTERMEMO''')
TABLE3=TABLE1-TABLE2
任何人都可以告诉我该怎么做...这将非常有用，谢谢
