描述

tuple_findtuple_findTupleFindTupleFindTupleFindtuple_find searches TupleTupleTupleTupletupletuple sequentially for all occurrences of the values of the second tuple ToFindToFindToFindToFindtoFindto_find and returns the indices in IndicesIndicesIndicesIndicesindicesindices (in relation to the first input tuple TupleTupleTupleTupletupletuple). For example, if TupleTupleTupleTupletupletuple contains the values [3,4,5,6,1,2,3,4,0] and ToFindToFindToFindToFindtoFindto_find contains the values [3,4], the output tuple IndicesIndicesIndicesIndicesindicesindices will contain the values [0,6]. If the first tuple does not contain the second tuple as a subtuple, tuple_findtuple_findTupleFindTupleFindTupleFindtuple_find returns -1 in IndicesIndicesIndicesIndicesindicesindices. It is allowed to mix strings and numbers in the input tuples.

例外：空输入元组

If either or both of the input tuples are empty, the operator returns an empty tuple.
