OpenEdge Data Management: DataServer for Microsoft SQL Server

Overflow checking
Error handling
Overflow checking is a process by which the DataServer evaluates whether the value defined
for a data type exceeds the data type’s capacity. If the value is greater than the bit size defined
for a data type, an error message occurs.
Beginning with OpenEdge Release 10.1B, all in-memory operations on INTEGER and INT64 data
types are now 64-bit, promoting potential conflicts when data is exchanged between OpenEdge
Release 10.1A and earlier OpenEdge clients, and 10.1B MS SQL Server DataServers. For
example, if a networked 10.1B DataServer produces an INT64 data type that is sent to a
pre-10.1B client, and the INT64 data type is mapped to a 32-bit data type that exceeds 32-bits of
data storage, the MS SQL Server will detect an overflow condition and an error message
appears on the client machine.
