You can select dates that are two years apart in SQL using a self-join and date difference functions. The exact syntax will depend on your specific database system (e.g., MySQL, PostgreSQL, SQL Server, etc.), as the date functions vary. Here are examples for a few common systems: ____________________________________________________________________________using mysql SELECT t1.date_start1, t2.date_start1 FROM your_table t1 JOIN your_table t2 ON ABS(YEAR(t2.date_start1) - YEAR(t1.date_start1)) = 2;
-- To also get the ID SELECT t1.id, t1.date_start1, t2.id, t2.date_start1 FROM your_table t1 JOIN your_table t2 ON ABS(YEAR(t2.date_start1) - YEAR(t1.date_start1)) = 2;
