Processing considerations for 32-bit and 64-bit data types

Starting with OpenEdge Release 10.1B, DataServer for MS SQL Server supports an existing or new 32-bit INTEGER data type defined in ABL. However, the internal bit size for an INTEGER data type and ROWID will automatically expand from a 32-bit field size to a 64-bit field size to accommodate larger values. In most situations, this expansion also supports the option to convert a database column from a 32-bit INTEGER to a 64-bit INT64 without performing a dump and load. For more details about ROWIDs, see ROWID function. Also, refer to the following sources for additional language details about INT64 and ROWID:
