在读这篇文章以前首先要提醒大家,Access 本身的报表也具有很强的实用性和强大的功能,只有当你发掘了其本身全部的功能却仍不能满足你对报表的特殊要求时才请使用 Excel 输出报表。很明显,使用 Excel 输出报表第一个弱点就是必须同时打开 Access 和 Excel (
首先找到 VBA 编程界面并找到"工具"菜单并单击"引用..."菜单项,在弹出的"引用"窗体中找到"现有引用"列表,在名为"Microsoft Excel x.0 Object Library"的项目前的方框内打钩。
其次,你要做好一张空白的 Excel 电子表格,设定好显示字体、边框、打印纸张等等并将其存盘。(以下示例中该表格名为 "temp.xls" )当然啦,直接使用空白的 Excel 文件也是可以的,不过你要编程自动生成表格边框、背景颜色、单元格格式等一些内容,这些涉及到 Excel 编程,我以后会在 Excel 专栏里详细叙述,这里就不多说了。
然后你就可以在 Access 里面制作你自己的打印预览窗体了,在窗体中安排 2 个命令按钮,考试,大提示在名为预览的按钮的 click 事件里输入以下代码:
Private Sub ExcelPreview_Click()
Dim xlApp As Excel.Application
Dim xlBook As Workbook, xlSheet As Worksheet
Set xlApp = CreateObject("Excel.Application")
Set xlApp = New Excel.Application
xlApp.Visible = True
Set xlBook = xlApp.Workbooks.Open("c:reprottemp.xls")
Set xlSheet = xlBook.Worksheets(1)
xlSheet.Cells(3, 1) = "制表日期:" + "12" + " 月"
'以上只更改了一个单元格内的数据,可根据需要无限次加入
xlBook.Save
xlSheet.PrintPreview '如果是要打印,只要把 PrintPreview 改为 PrintOut
xlBook.close
xlApp.Quit
End Sub
OK,然后就可以单击该按钮看看生成的表格如何了

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

The steps to build a MySQL database include: 1. Create a database and table, 2. Insert data, and 3. Conduct queries. First, use the CREATEDATABASE and CREATETABLE statements to create the database and table, then use the INSERTINTO statement to insert the data, and finally use the SELECT statement to query the data.

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.

MySQL is suitable for beginners because: 1) easy to install and configure, 2) rich learning resources, 3) intuitive SQL syntax, 4) powerful tool support. Nevertheless, beginners need to overcome challenges such as database design, query optimization, security management, and data backup.

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.

MySQL is not only a database management system (DBMS) but also closely related to programming languages. 1) As a DBMS, MySQL is used to store, organize and retrieve data, and optimizing indexes can improve query performance. 2) Combining SQL with programming languages, embedded in Python, using ORM tools such as SQLAlchemy can simplify operations. 3) Performance optimization includes indexing, querying, caching, library and table division and transaction management.

MySQL uses SQL commands to manage data. 1. Basic commands include SELECT, INSERT, UPDATE and DELETE. 2. Advanced usage involves JOIN, subquery and aggregate functions. 3. Common errors include syntax, logic and performance issues. 4. Optimization tips include using indexes, avoiding SELECT* and using LIMIT.
