在SQL中,您可以使用以下几种方式添加序号:
SELECT ROW_NUMBER() OVER (ORDER BY column_name) AS row_number, column_name
FROM table_name;
CREATE TABLE table_name (
id INT AUTO_INCREMENT PRIMARY KEY,
column_name data_type,
...
);
SET @row_number = 0;
INSERT INTO table_name (column_name)
SELECT (@row_number := @row_number + 1), column_name
FROM other_table;
这些都是常见的在SQL中添加序号的方式,具体使用哪种方式取决于您的需求和所使用的DBMS。
