Question

How could I split a date range like this

20120301-20120331

into two different dates in T-SQL? The data appears in a column called date_range.

Thanks!

Assuming SQL Server:

DECLARE @string VARCHAR(17) = '20120301-20120331';

SELECT 
    CONVERT(DATETIME, LEFT(@string, 8)), 
    CONVERT(DATETIME, RIGHT(@string, 8));

From a table:

SELECT 
    CONVERT(DATETIME, LEFT(column_name, 8)),
    CONVERT(DATETIME, RIGHT(column_name, 8))
FROM dbo.table_name;
