在 SQL 中，可以使用以下几种实用技巧来获取周数：

SELECT DATE_FORMAT(your_date, '%W') AS week_number
FROM your_table;

SELECT WEEK(your_date) AS week_number
FROM your_table;

SELECT DATE_PART('week', your_date) AS week_number
FROM your_table;

SELECT EXTRACT(WEEK FROM your_date) AS week_number
FROM your_table;

SELECT ISOWEEK(your_date) AS week_number
FROM your_table;

SELECT TO_CHAR(TRUNC(your_date, 'WW'), 'WW') AS week_number
FROM your_table;

请将 your_date 和 your_table 替换为实际的日期字段和表名。这些函数将帮助您获取日期所在周的周数。
