arrays.join_string
arrays.join_string(array_of_strings, optional_delimiter)
說明
將字串陣列轉換為單一字串,並以選用參數分隔。如未提供分隔符號,系統會使用空字串。
參數資料類型
ARRAY_STRINGS
、STRING
傳回類型
STRING
程式碼範例
以下列舉幾個函式使用範例:
範例 1
這個範例會使用分隔符號,將陣列與非空值元素聯結。
arrays.join_string(["foo", "bar"], ",") = "foo,bar"
範例 2
這個範例會將陣列與空值元素和分隔符號合併。
arrays.join_string(["foo", NULL, "bar"], ",") = "foo,bar"
範例 3
這個範例會將陣列與非空值元素聯結,且不含分隔符號。
arrays.join_string(["foo", "bar"]) = "foobar"
