SELECT * FROM table_name GROUP BY column_name HAVING COUNT(*) > 1;
SELECT * FROM 表名 WHERE 列名 IN (SELECT 列名 FROM 表名 GROUP BY 列名 HAVING COUNT(*) > 1);
要查询SQL数据库中相同的数据，可以使用GROUP BY和HAVING子句。，，``sql，SELECT column_name, COUNT(*)，FROM table_name，GROUP BY column_name，HAVING COUNT(*) > 1;，``，，这段代码会返回在指定列中出现次数超过一次的所有数据。
SELECT * FROM table_name GROUP BY column_name HAVING COUNT(*) > 1;
SQL查询相同是指使用SQL语言查找数据库中具有相同属性值的记录。
要查询重复数据，可以使用SQL中的GROUP BY和HAVING子句。假设你有一个名为users的表，并且你想查找在email列中重复的数据，你可以使用以下SQL语句：，，``sql，SELECT email, COUNT(*)，FROM users，GROUP BY email，HAVING COUNT(*) > 1;，`，，这个查询会返回所有在email`列中出现超过一次的记录及其出现的次数。
SELECT column1, COUNT(*) FROM table_name GROUP BY column1 HAVING COUNT(*) > 1;
SELECT COUNT(*) FROM (SELECT column_name, COUNT(*) FROM table_name GROUP BY column_name HAVING COUNT(*) > 1) AS duplicates;
SELECT * FROM 表名 GROUP BY 列名 HAVING COUNT(*) > 1;
SELECT * FROM 表名 GROUP BY 列名 HAVING COUNT(*) > 1;
