mi_boolean 
mi_eval_am_qual(MI_ROW *row, MI_AM_QUAL_DESC *qualDesc);

row

points to the row structure.

qualDesc

points to the qualification descriptor.

The am_getnext purpose function can call mi_eval_am_qual() to obtain results for any qualifications that the access method cannot complete. Before the access method can call mi_eval_am_qual(), it must call mi_row_create() to assemble a row. For a detailed procedure and examples, refer to Processing Complex Qualifications.

If mi_eval_am_qual() returns MI_TRUE, am_getnext returns MI_ROWS. If mi_eval_am_qual() returns MI_FALSE, am_getnext disregards the current row, does not return a value, and starts to evaluate the next row.

MI_TRUE indicates that the row qualifies. MI_FALSE indicates that the row does not qualify.

See the description of function mi_init_am_qual().
