[Mark916]

[zeweilin]

I have the same problem... how should i solve this problem ?

[yu285]

what is the JDBC version we used ?

it should be 3.0.0 , please confirm this ~

[yu285]

I guess it is an authority problem for a Windows user.

There is a taos.dll under C:\TDengine\driver ，please copy it to C:\Windows\System32 ,if it already existed just overwrite it

[steven-design]

I try to copy C:\TDengine\driver\taos.dll to C:\Windows\System32, JDBC version set 3.0.0 but, the problem remains.
