在 Python 脚本中执行 SQL 存储过程

Question

我正在尝试在 Python 脚本中执行 SQL 存储过程，但语法有问题。我尝试了我发现的各种示例的组合，但 none 似乎有效。这是我尝试过的：

county = 100200
confirmed = 123456
death = 12
labTestCount = 0    
#Example1
conn.execute('{CALL [spInsertCOVIDData](@County,@Confirmed,@Death,@LabTestCount)}', ('county', 'confirmed', 'death', 'labTestCount'))

#Example2
query = "EXEC [spInsertCOVIDData] (@County,@Confirmed,@Death,@LabTestCount)", (county, confirmed, death, labTestCount)
conn.execute(query)

#Example3
query = "EXEC [spInsertCOVIDData] @County=?, @Confirmed=?, @Death=?, @LabTestCount=?",(county, confirmed, death, labTestCount)
conn.execute(query)

#Example4
query = "EXEC [spInsertCOVIDData] @County='county', @Confirmed='confirmed', @Death='death', @LabTestCount='labTestCount'"
conn.execute(query)

我混合了各种错误：

('The SQL contains 0 parameter markers, but 4 parameters were supplied', 'HY000')

或

The first argument to execute must be a string or unicode query.

您可以尝试在语句中使用参数，使用 ? 作为占位符并传递每个参数的实际值：

county = 100200
confirmed = 123456
death = 12
labTestCount = 0

query = "EXEC [spInsertCOVIDData] @County=?, @Confirmed=?, @Death=?, @LabTestCount=?"
conn.execute(query, (county, confirmed, death, labTestCount))
