在Access2007中使用查询向导虽然可以快速地创建查询,但是对于创建指定条件的查询、参数查询和其他复杂的查询查询向导就不能完全胜任了。这种情况下,可以使用设计视图”直接创建查询,或者使用查询向导创建查询后,再在设计视图中进行修改。
  例  在“教学管理”数据库 中,查询成绩优秀的学生的
“学号”、“姓名”、“课程”和“成绩”。操作步骤如下:

  (1)打开“教学管理”数据库,在“创建”选项卡上的“其他”组中,单击“查询设计”按钮,打开“查询设计视图”窗口,如图1所示。

  在Access2007中<strong使用”设计视图创建查询>

  图1  “查询设计视图”窗口

  (2)在“显示表”对话框中,选中“学生”、“课程”和“成绩”表,然后单击“添加”按钮,把这三个表添加到设计网格上部的“数据源区域”窗格中。添加后,在这些表之间自动显示出它们之间的“关系”。最后单击“关闭”按钮,关闭“显示表”对话框。

  (3)在“学生”表中,把“学号”、“姓名”字段拖到
设计网格中。用同样的方法把“课程”表中的“课程名”字段和“成绩”表中的“期末成绩”字段,添加到设计网格中。

  (4)在设计网格的“期末成绩”列的“条件”行的单元格中,输入条件“>=90”,此时的设计视图如图2所示。

  (5)在“创建”选项卡上的“结果”组中,单击按钮,打开“查询视图”,显示查询结果。

  (6)在快捷工具栏上,单击“保存”按钮,打开“另存为”对话框,输入查询名称“成绩优秀学生”,单击“确定”按钮。

  提示:在多表查询时,表与表之间,应首先建立关系。若没有建立关系,则多表查询将会造成出现多余重复纪录的混乱情况

MySQL's Place: Databases and ProgrammingMySQL's Place: Databases and ProgrammingApr 13, 2025 am 12:18 AM

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL: From Small Businesses to Large EnterprisesMySQL: From Small Businesses to Large EnterprisesApr 13, 2025 am 12:17 AM

MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.

What are phantom reads and how does InnoDB prevent them (Next-Key Locking)?What are phantom reads and how does InnoDB prevent them (Next-Key Locking)?Apr 13, 2025 am 12:16 AM

InnoDB effectively prevents phantom reading through Next-KeyLocking mechanism. 1) Next-KeyLocking combines row lock and gap lock to lock records and their gaps to prevent new records from being inserted. 2) In practical applications, by optimizing query and adjusting isolation levels, lock competition can be reduced and concurrency performance can be improved.

MySQL: Not a Programming Language, But...MySQL: Not a Programming Language, But...Apr 13, 2025 am 12:03 AM

MySQL is not a programming language, but its query language SQL has the characteristics of a programming language: 1. SQL supports conditional judgment, loops and variable operations; 2. Through stored procedures, triggers and functions, users can perform complex logical operations in the database.

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

The Importance of MySQL: Data Storage and ManagementThe Importance of MySQL: Data Storage and ManagementApr 12, 2025 am 12:18 AM

MySQL is an open source relational database management system suitable for data storage, management, query and security. 1. It supports a variety of operating systems and is widely used in Web applications and other fields. 2. Through the client-server architecture and different storage engines, MySQL processes data efficiently. 3. Basic usage includes creating databases and tables, inserting, querying and updating data. 4. Advanced usage involves complex queries and stored procedures. 5. Common errors can be debugged through the EXPLAIN statement. 6. Performance optimization includes the rational use of indexes and optimized query statements.

Why Use MySQL? Benefits and AdvantagesWhy Use MySQL? Benefits and AdvantagesApr 12, 2025 am 12:17 AM

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

Describe InnoDB locking mechanisms (shared locks, exclusive locks, intention locks, record locks, gap locks, next-key locks).Describe InnoDB locking mechanisms (shared locks, exclusive locks, intention locks, record locks, gap locks, next-key locks).Apr 12, 2025 am 12:16 AM

InnoDB's lock mechanisms include shared locks, exclusive locks, intention locks, record locks, gap locks and next key locks. 1. Shared lock allows transactions to read data without preventing other transactions from reading. 2. Exclusive lock prevents other transactions from reading and modifying data. 3. Intention lock optimizes lock efficiency. 4. Record lock lock index record. 5. Gap lock locks index recording gap. 6. The next key lock is a combination of record lock and gap lock to ensure data consistency.
