split_by_string
description
Syntax
ARRAY<STRING> split_by_string(STRING s, STRING separator)
将字符串拆分为由字符串分隔的子字符串。它使用多个字符的常量字符串分隔符作为分隔符。如果字符串分隔符为空,它将字符串拆分为单个字符数组。
example
select split_by_string('a1b1c1d','1');
+---------------------------------+
| split_by_string('a1b1c1d', '1') |
+---------------------------------+
| ['a', 'b', 'c', 'd'] |
+---------------------------------+
select split_by_string(',,a,b,c,',',');
+----------------------------------+
| split_by_string(',,a,b,c,', ',') |
+----------------------------------+
| ['', '', 'a', 'b', 'c', ''] |
+----------------------------------+
SELECT split_by_string(NULL,',');
+----------------------------+
| split_by_string(NULL, ',') |
+----------------------------+
| NULL |
+----------------------------+
select split_by_string('a,b,c,abcde',',');
+-------------------------------------+
| split_by_string('a,b,c,abcde', ',') |
+-------------------------------------+
| ['a', 'b', 'c', 'abcde'] |
+-------------------------------------+
select split_by_string('1,,2,3,,4,5,,abcde', ',,');
+---------------------------------------------+
| split_by_string('1,,2,3,,4,5,,abcde', ',,') |
+---------------------------------------------+
| ['1', '2,3', '4,5', 'abcde'] |
+---------------------------------------------+
select split_by_string(',,,,',',,');
+-------------------------------+
| split_by_string(',,,,', ',,') |
+-------------------------------+
| ['', '', ''] |
+-------------------------------+
select split_by_string(',,a,,b,,c,,',',,');
+--------------------------------------+
| split_by_string(',,a,,b,,c,,', ',,') |
+--------------------------------------+
| ['', 'a', 'b', 'c', ''] |
