This determines the behavior for converting Oracle data with datatype number. A distinct number_mode setting can be defined for each service.
With a setting of 1, ECDA Option for Oracle attempts to return data as tinyint, smallint, int, float or numeric. Overflows are possible.
A setting of 0 was used to support pre-system 10 servers. However, because pre-system 10 servers are no longer supported by ECDA Option for Oracle, a setting of 2 causes all numbers to be returned as numeric. This setting gives the best performance and is the default.
The following table describes how data is returned, based on the number_mode parameter and scale value of the Oracle number datatype.
Scale |
number_mode = 0 |
number_mode = 1 |
number_mode = 2 |
|---|---|---|---|
scale = 0 |
If 0 <= precision <=9 Send back as shown in Table A-5, else send back data as float. |
If 0 <= precision <=9, send back as shown else if precision is valid, send back data as numeric, else send back data as float. |
If precision is valid, send back data as numeric, else send back data as float. |
scale !=0 |
Send back data as float. |
If valid precision and scale, send back data as numeric, else send back data as float. |
If valid precision and scale, send back data as numeric. |
