tuple_find_firsttuple_find_firstTupleFindFirstTupleFindFirst (Operator)

Name

tuple_find_firsttuple_find_firstTupleFindFirstTupleFindFirst — Return the index of the first occurrence of a tuple within another tuple.

Signature

Description

tuple_find_firsttuple_find_firstTupleFindFirstTupleFindFirstTupleFindFirst searches forward through TupleTupleTupleTupletuple for the first occurrence of the values of the second tuple ToFindToFindToFindToFindtoFind and returns the IndexIndexIndexIndexindex (in relation to the first input tuple TupleTupleTupleTupletuple). For example, if TupleTupleTupleTupletuple contains the values [3,4,5,6,1,2,3,4,0] and ToFindToFindToFindToFindtoFind contains the values [3,4], the output IndexIndexIndexIndexindex is 0. If the first tuple does not contain the second tuple as a subtuple, tuple_find_firsttuple_find_firstTupleFindFirstTupleFindFirstTupleFindFirst returns -1 in IndexIndexIndexIndexindex. It is allowed to mix strings and numbers in the input tuples.

Exception: Empty input tuples

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