描述

tuple_jointuple_joinTupleJoinTupleJoinTupleJointuple_join joins the strings of the input tuple StringsStringsStringsStringsstringsstrings interleaved with the separators defined in the input tuple SeparatorsSeparatorsSeparatorsSeparatorsseparatorsseparators and returns the result in the tuple JoinedStringsJoinedStringsJoinedStringsJoinedStringsjoinedStringsjoined_strings。

For each string element in SeparatorsSeparatorsSeparatorsSeparatorsseparatorsseparators, there is one corresponding element in JoinedStringsJoinedStringsJoinedStringsJoinedStringsjoinedStringsjoined_strings which holds the elements of StringsStringsStringsStringsstringsstrings joined by this separator. Thereby an empty string in SeparatorsSeparatorsSeparatorsSeparatorsseparatorsseparators corresponds to simple string concatenation.

Example: StringsStringsStringsStringsstringsstrings = ['aaa', 'bbb', 'ccc', 'ddd']["aaa", "bbb", "ccc", "ddd"]["aaa", "bbb", "ccc", "ddd"]["aaa", "bbb", "ccc", "ddd"]["aaa", "bbb", "ccc", "ddd"]["aaa", "bbb", "ccc", "ddd"] and SeparatorsSeparatorsSeparatorsSeparatorsseparatorsseparators = ['++', '--', '']["++", "--", ""]["++", "--", ""]["++", "--", ""]["++", "--", ""]["++", "--", ""]. In this case the operator returns the tuple JoinedStringsJoinedStringsJoinedStringsJoinedStringsjoinedStringsjoined_strings = ['aaa++bbb++ccc++ddd', 'aaa--bbb--ccc--ddd', 'aaabbbcccddd']["aaa++bbb++ccc++ddd", "aaa--bbb--ccc--ddd", "aaabbbcccddd"]["aaa++bbb++ccc++ddd", "aaa--bbb--ccc--ddd", "aaabbbcccddd"]["aaa++bbb++ccc++ddd", "aaa--bbb--ccc--ddd", "aaabbbcccddd"]["aaa++bbb++ccc++ddd", "aaa--bbb--ccc--ddd", "aaabbbcccddd"]["aaa++bbb++ccc++ddd", "aaa--bbb--ccc--ddd", "aaabbbcccddd"].

Both input tuples (StringsStringsStringsStringsstringsstrings and SeparatorsSeparatorsSeparatorsSeparatorsseparatorsseparators) may only consist of strings. Otherwise tuple_jointuple_joinTupleJoinTupleJoinTupleJointuple_join returns an error.

例外：空输入元组

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

Unicode 码点与字节

A separator always consists of the entire string. This is true regardless of the system setting of 'tsp_tuple_string_operator_mode'"tsp_tuple_string_operator_mode""tsp_tuple_string_operator_mode""tsp_tuple_string_operator_mode""tsp_tuple_string_operator_mode""tsp_tuple_string_operator_mode".
