在Oracle SQL中,可以使用以下方法来通过编程方式处理重复的数据:
SELECT DISTINCT column1, column2
FROM table_name;
CREATE TABLE new_table AS
SELECT column1, column2, ROW_NUMBER() OVER(PARTITION BY column1, column2 ORDER BY column1) AS rn
FROM table_name;
DELETE FROM new_table WHERE rn > 1;
WITH cte AS (
SELECT column1, column2, ROW_NUMBER() OVER(PARTITION BY column1, column2 ORDER BY column1) AS rn
FROM table_name
)
DELETE FROM cte WHERE rn > 1;
这些是一些通过编程方式处理Oracle SQL中重复数据的方法。根据具体情况选择最适合的方法。
