index

index is the field whose precision will be retrieved.

The possible values of index depend upon the value of ingres.array_index_start. If ingres.array_index_start is 1 (the default) then index must be between 1 and the value returned by ingres_num_fields(). If ingres.array_index_start is 0 then index must be between 0 and ingres_num_fields() - 1.
