python - 如何从 django 为 SQL Server 执行原始 sql 语句？

Question

有效的原始数据库查询：

SELECT *
FROM [db_name].[dbo].[table]
WHERE name IN (
SELECT name
FROM [db_name].[dbo].[table]
WHERE active = 1
Group by name
Having count(*) > 1
)
order by name

当我尝试从 django 执行它时

from django.db import connection

def fetch_matching_pn_products():
    with connection.cursor() as cursor:
        cursor.execute("SELECT *"
                        "FROM db_name.dbo.table"
                        "WHERE name IN ("
                        "SELECT name"
                        "FROM db_name.dbo.table"
                        "WHERE active = 1"
                        "Group by name"
                        "Having count(*) > 1"
                        ")"
                        "order by name")
        data = cursor.fetchall()
    return data

返回此错误

django.db.utils.ProgrammingError: ('42000', "[42000] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Incorrect syntax near the keyword 'IN'. (156) (SQLExecDirectW); [42000] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Incorrect syntax near '.'. (102)")

我也尝试过将db_name.dbo.tabledjango更改[db_name].[dbo].[table]为table但没有成功。需要更改哪些内容才能正确执行原始查询？

Answer 1

在每个".

没有空格，字符串包含SELECT nameFROM等，这是不正确的，因为 FROM 应该是一个单独的单词。
