数据查询语言（Data Query Language, DQL） SELECT SELECT * FROM table_name: 用于从指定表中选取所有列。 WHERE 子句：用于过滤结果集，只返回满足条件的记录。 示例： SELECT * FROM stock_information WHERE stockid = 'nid' AND stockname = 'str_name' 使用 LIKE 进行模糊匹配：stockname LIKE '%findthis%' 表示匹配包含“findthis”的字符串。 特殊的 LIKE 表达式：stockname LIKE '[a-zA-Z]%' 表示以字母开头的字符串；stockname LIKE '^[^F-M]%' 表示排除 F 到 M 之间的字母开头的字符串。 使用 OR 和 AND 组合多个条件：OR stockpath = 'stock_path' AND stockindex = 24 使用 NOT 关键字：NOT stocknumber = 10 使用 BETWEEN 指定一个范围：stocknumber BETWEEN 20 AND 100 使用 IN 指定一个值列表：stocknumber IN (10, 20, 30) 排序：ORDER BY stockid DESC 表示按降序排列；ORDER BY 1, 2 表示按第一列和第二列排序。 子查询：stockname = (SELECT stockname FROM stock_information WHERE stockid = 4) 表示内层查询的结果作为外层查询的条件。 DISTINCT SELECT DISTINCT column_name FROM table_name 用于返回唯一不重复的值。
