Returns the sequence number for the specified entry in the <rs_threads> system table.
A number of <int>< >datatype. It represents the ID of the entry to be checked and matches the value of the <id> column in the <rs_threads> system table.
Creates an rs_get_thread_seq function string that executes a select statement in the <rs_threads> table.

Replication Server executes rs_get_thread_seq to check the completion status of preceding transactions. It is executed only when more than one DSI thread is defined for a connection. The function returns a single row with a single column, <seq>, which contains the sequence number for the specified ID.
The thread invoking this function is blocked until the transaction that last modified the specified entry completes its transaction.
rs_get_thread_seq has function-string-class scope.
Replication Server creates an initial rs_get_thread_seq function string for the system-provided function-string classes during installation.
If you use a user-created base function-string class and you use the parallel DSI feature, you must create a function string for the rs_get_thread_seq function. If you do not use parallel DSI, you do not need to create a function string for this function.
Create or customize an rs_get_thread_seq function string at the Replication Server that is the primary site for the class.
