我有以下演示代码可以正常工作,但我想捕获 STATISTICS IO 的输出。我找不到捕捉这一点的正确方法。
import adodbapi
server = 'MYCOMPUTER\SQLEXPRESS'
database = 'mytest'
connString = 'Provider=SQLOLEDB;Server=' + server + ';Database=' + database + ';Integrated Security=SSPI;'
print(connString)
myConn = adodbapi.connect(connString)
cursor = myConn.cursor()
cursor.execute('SET STATISTICS IO ON; SELECT * FROM dbo.mytab')
results = cursor.fetchall()
for i in results:
print("First value: {} and Second value: {}".format(i[0],i[1]))
我尝试了这段代码,它是从另一个stackoverflow答案中提取的,但没有成功:
import adodbapi
import win32com
import pythoncom
##from win32com.client import gencache
##gencache.EnsureModule('{2A75196C-D9EB-4129-B803-931327F72D5C}', 0, 2, 8)
defaultNamedOptArg=pythoncom.Empty
defaultNamedNotOptArg=pythoncom.Empty
defaultUnnamedArg=pythoncom.Empty
class events():
def OnInfoMessage(self, pError, adStatus, pConnection):
print('Info Message')
a = pError.QueryInterface(pythoncom.IID_IDispatch)
a = win32com.client.Dispatch(a)
print(a.Description)
print(a.Number)
print(a.Source)
#print 'B', adStatus
c = pConnection.QueryInterface(pythoncom.IID_IDispatch)
c = win32com.client.Dispatch(c)
print(c.Errors.Count)
print(c.Errors.Item(0).Description)
print(c.Errors.Clear())
print('c', adStatus)
if __name__ == '__main__':
server = 'mybox\SQLEXPRESS'
database = 'mytest'
username = 'testusr'
password = 'password'
connString = 'Provider=SQLOLEDB;Server=' + server + ';Database=' + database + ';Integrated Security=SSPI;'
print(connString)
myConn = win32com.client.DispatchWithEvents("ADODB.Connection", events)
myConn.ConnectionString = connString
myConn.Open()
con = adodbapi.cursor(myConn)
cursor = con.cursor()
cursor.execute('SET STATISTICS IO ON; SELECT * FROM dbo.mytab')
results = cursor.fetchall()
for i in results:
print("First value: {} and Second value: {}".format(i[0],i[1]))
我收到此错误:
