Assume that you have Microsoft SQL Server 2008 Service Pack 3 (SP3), SQL Server 2008 R2 Service Pack 2 (SP2), SQL Server 2012 Service Pack 2 (SP2), SQL Server 2012 Service Pack 1(SP1), or SQL Server 2014 installed on a computer. When you call the sp_MScreatemergedynamicsnapshot stored procedure to create a dynamic snapshot, you receive the following error messages:
Msg 8115, Level 16, State 2, Procedure sp_MScreatemergedynamicsnapshot, Line 182
Arithmetic overflow error converting expression to data type nvarchar.
Msg 20655, Level 16, State 1, Procedure sp_MScreatemergedynamicsnapshot, Line 186
The partitioned snapshot process cannot complete. Cannot retrieve the maximum timestamp information from the MSsnapshot_history table in the distribution database. Ensure that a standard snapshot is up-to-date and available.
Msg 20628, Level 16, State 1, Procedure sp_MScreatemergedynamicsnapshot, Line 203
Failed to generate dynamic snapshot.
Note This issue occurs when the agent_id value exceeds 99,999 in the MSdynamicsnapshotjobs table.
This issue occurs because of a defect in SQL Server. The type of the local variable for agent_id is a char, and its length is 5. An arithmetic overflow may occur when SQL Server handles the value that is assigned to INT type.
