以下是一些常用的 Access 数据库 SQL 语句:
- 创建表格:
CREATE TABLE table_name
(
column1 datatype,
column2 datatype,
column3 datatype,
…
); - 查询数据:
SELECT column1, column2, …
FROM table_name
WHERE condition; - 插入数据:
INSERT INTO table_name (column1, column2, …)
VALUES (value1, value2, …); - 更新数据:
UPDATE table_name
SET column1 = value1, column2 = value2, …
WHERE condition; - 删除数据:
DELETE FROM table_name
WHERE condition; - 添加索引:
CREATE INDEX index_name
ON table_name (column1, column2, …); - 删除索引:
DROP INDEX index_name
ON table_name; - 创建视图:
CREATE VIEW view_name AS
SELECT column1, column2, …
FROM table_name
WHERE condition;
以上是一些常用的 Access 数据库 SQL 语句,可以根据具体的需求进行调整和组合使用。

ORDER BY column1 ASC/DESC; - 聚合函数:
SELECT COUNT(column_name)
FROM table_name;
SELECT AVG(column_name)
FROM table_name;
SELECT SUM(column_name)
FROM table_name;
- 连接表格:
SELECT column_name(s)
FROM table1
INNER JOIN table2
ON table1.column_name = table2.column_name; - 创建索引:
CREATE INDEX index_name
ON table_name (column_name);
