[FB4] Description of RDB$FUNCTION_ARGUMENTS::RDB$MECHANISM #192
Comments
Thanks, I'll add it when I have time. |
BTW: Is this only for Firebird 4+ or also for older versions? |
These constants were added in FB v2.0, if I understand correctly. FB2 source (types.h): TYPE("BY_VALUE", 0, nam_mechanism)
TYPE("BY_REFERENCE", 1, nam_mechanism)
TYPE("BY_VMS_DESCRIPTOR", 2, nam_mechanism)
TYPE("BY_ISC_DESCRIPTOR", 3, nam_mechanism)
TYPE("BY_SCALAR_ARRAY_DESCRIPTOR", 4, nam_mechanism)
TYPE("BY_REFERENCE_WITH_NULL", 5, nam_mechanism) FB1.5.4.4910 source (types.h): TYPE("BY_VALUE", 0, nam_mechanism)
TYPE("BY_REFERENCE", 1, nam_mechanism)
TYPE("BY_VMS_DESCRIPTOR", 2, nam_mechanism)
TYPE("BY_ISC_DESCRIPTOR", 3, nam_mechanism)
TYPE("BY_SCALAR_ARRAY_DESCRIPTOR", 4, nam_mechanism) Although FB1.5 has SCALAR_ARRAY-constant, it does not support the creation of UDF with such arguments (I tested this): |
Given the language references only start at 2.5, the behaviour for Firebird 1.5 is not important :) |
Ok :)

Added to fblangref25 - fblangref50; this will be published at a later time (hoping/waiting for more changes to accumulate). |
