Python/sqlwhere子句不适用于所有行

Question

在我构建的Python程序中，以下代码有问题。该程序从数据库中提取数据，并根据它们输入的参考号列表'GrantRefNumber'将其放入Excel电子表格中。你知道吗

它可以工作，但由于某些原因，只有第一个引用号应用了'a.reporting_period_id like 'none-'，其余的没有。你知道吗

我在SQL代码中使用一个变量替换，将引用号列表放入字符串中。你知道吗

任何帮助都将不胜感激！你知道吗

SQL:

"SELECT a.fa_reference as [GrantRefNumber], 
a.fa_name as [Award Title], 
a.location as [RO], 
ISNULL(cat.grant_department_name, '') as [Department], 
a.funding_start_date as [Start Date], 
a.funding_end_date as [End Date], 
a.[pi]    as [PI ID],
a.pi_initials  as [PI Name], 
a.pi_surname as [PI Surname],  
r1_2 as [Type], 

DATEADD(s, cast(last_submitted_date as int), '1970-01-01 00:00:00') as [Submitted Date]  

from keywordagreements a inner join entries_publications p on a.id =  
p.agreement_id left outer join mrc_categories cat  on a.origid = cat.id and cat.centre not in ('2') 

where a.[pi] NOT LIKE 'S%' and response_code not like 'Test' and Closed is null  
and a.reporting_period_id like 'none-'
and a.funding_organisation not like '%UKSA%' and {}' 

Order by [RO], [PI ID], [GrantRefNumber]".format(finalList)

finalList（变量替换）：

finalList是一个引用号列表，我从Python中的用户那里得到，名为“items”

items = dfCall['GrantRefNumber'].values.tolist()
refList = " OR ".join(["a.fa_reference LIKE '%s'" % num for num in items])
finalList = refList[:-1]

我正在使用PYODBC提取数据。你知道吗

我的代码中的SQL如下所示（我在前面的代码中删除了引号（和一些列），以使其更易于阅读）：

          " a.location  as [RO], ISNULL(cat.grant_department_name, '') as [Department]," \

Answer 1

我不知道你的format命令替代了什么。下面是format命令的几个示例：

'This is a {} string.'.format('formatted')
'This is a {0} {1}.'.format('formatted', 'string')
'This is a {replace_me} {replace_me_2}.'.format(replace_me='formatted', replace_me_2='string')

输出This is a formatted string.

您需要修改SQL以将finalList插入到SQL中。由于我们看不到您的全部代码，因此您可能希望使用三重引号格式来支持多行：

sql = """
    SELECT * FROM table
    WHERE blah = '{string_to_compare}'
""".format(string_to_compare='blah')

要非常小心，在任何SQL查询中使用字符串替换时，都会出现SQL注入。祝你好运！你知道吗

Answer 2

好的，我想我已经修好了。我将{}'放在方括号中，即({}')，因为它将其他引用号视为一个单独的语句，因为OR命令。你知道吗
