sa_server_messages system procedure

Allows you to return messages from the database server messages window as a result set.

Syntax 
sa_server_messages( [ first_msg ] [, num_msgs ] )
Arguments

  • first_msg   Use this optional UNSIGNED BIGINT parameter to specify the ID of the first or last message to be returned, depending on the sign of the num_msgs parameter. The default is NULL, which means that the search starts at the beginning of the list if num_msgs is NULL or non-negative; the search starts past the end of the list if num_msgs is negative.

  • num_msgs   Use this optional BIGINT parameter to specify the number of messages to be returned. The sign indicates whether the request is for messages starting at first_msg or ending at first_msg. The default is NULL, which means that all messages starting at first_msg to the end of the list are returned.

Result set
