QueryTimeout

  • Last UpdatedNov 17, 2021

The QueryTimeout property is a read-write property that specifies the number of seconds to wait for a query to finish executing before the operation is aborted with a timeout error.

Syntax

aaServer.QueryTimeout = integer;

Result = aaServer.QueryTimeout;

Remarks

Changing the value of this property after log on has no effect until log off and subsequent log on.

The default value is 120. A value of 0 means no timeout. If you do not use a timeout, the application waits indefinitely when trying to query a server, which may cause it to hang if the server is unavailable.
