mi_integer  mi_qual_stratnum(MI_AM_QUAL_DESC *qualDesc)

qualDesc

points to the qualification descriptor.

The return value from mi_qual_stratnum() provides an offset to retrieve the strategy function name from the key descriptor. To obtain the strategy-function name, the access method can pass the return value from mi_qual_stratnum() to the mi_key_opclass_strat() function.

The return integer indicates the order in which the strategy function name occurs in the key descriptor. The mi_qual_stratnum() returns 0 for the first strategy function and 1 for the second strategy function name. For each subsequent strategy function, the return value increments by 1.

See the descriptions of functions mi_key_opclass_strat() and mi_qual_funcname().
