-------------------------------------------- |

– |
Even when dialect 3 quoted format parameter names are not supported, IBX still processes |
87 |
– |
parameter names case insensitive. This does result in some additional overhead |
88 |
– |
due to a call to "AnsiUpperCase". This can be avoided by undefining |
89 |
– |
"UseCaseInSensitiveParamName" below. |
90 |
– |
|
91 |
– |
Note: do not define "UseCaseSensitiveParamName" when "ALLOWDIALECT3PARAMNAMES" |
92 |
– |
is defined. This will not give a useful result. |
