Question

Hi all I am trying to write sql for selecting string between two special characters.

example: in the table, field value like 7185878969-129981041-000000 . how can I select only middle portion 129981041 without hard coding. What will be the best way to go about this?.Please provide sample code. Thanks

Answer 1

Impala具有split_part() ：

select split_part(col, '-', 2)

Answer 2

Try this for MySQL:

SELECT REVERSE(SUBSTRING_INDEX(REVERSE(SUBSTRING_INDEX(Column,'-',2)),'-',1))
FROM table_name;

Result :

129981041
