Description
This function resets an AccessKey secret. The AccessKey secret is used to access the OSS bucket that stores the data of a specified trajectory.
When you read trajectory data from a file in an OSS bucket, you must provide the AccessKey pair information to access the OSS bucket. An AccessKey pair consists of an AccessKey ID and an AccessKey secret. An AccessKey ID is similar to a username and an AccessKey secret is similar to a password.
Examples
select ST_SetAkSecret(traj, '<OSS_PWD>') from trajs;
st_setaksecret
