准备好的sql语句中整数的Python列表 [英] Python list of ints in prepared sql statement

问题描述

我的问题有点像 Python 字符串到 SQL 的列表IN 参数 但我有一个整数列表.我使用的python代码是:

My question is somewhat the same as Python list of String to SQL IN parameter but I have a list of integers. The python code I use is:

ids = [1000032, 1000048]
sql = 'SELECT CompNo, CompName, CompType FROM Component WHERE DeptID IN (?)'    
cursor.execute(sql, [','.join(ids)])

Sybase 数据库引擎响应为:

And the Sybase database engine responds with:

pyodbc.Error: ('07006', "[07006] [Sybase][ODBC Driver][SQL Anywhere]Cannot convert '1000032','1000048' to a numeric (-157) (SQLExecDirectW)")

这样做的正确方法是什么?

What is the correct way to do this?

推荐答案

IMO 使用 str.format

ids = [1000032, 1000048]
sql = 'SELECT CompNo, CompName, CompType FROM Component WHERE DeptID IN ({0})' 
sql = sql.format(','.join('?' * len(ids)))
cursor.execute(sql, (ids,))
...
