mapping

Use specific data mapping of version U3.0

USYS$ODx_PARAMS {=} mapping=3

Description

Use the mapping=3 option to revert to the data mapping behavior of the Uniface ODBC connector version U3.0 in the following areas:

  • If SQL_LONGVARCHAR is available, it will be used for SR* fields, even when SQL_LONGVARBINARY is also available.

  • If SQL_SMALLINT or SQL_INT is available, SQL_TINYINT will not be used for packing code I1—SQL_SMALLINT or SQL_INT will be used instead.

  • The connector will inform Uniface that it does not support variable record lengths. This means that the size of S CHAR and S VARCHAR fields stored in overflow tables is limited to 60 bytes.
