恢复从 Access 2000、 Access 2002 或 Access 2003 中数据库删除表的方法
注意 : 本文示例代码使用 Microsoft 数据访问对象。 为此代码才能正常运行, 您必须引用 Microsoft DAO 3.6 对象库。 可以进行, 单击 工具 菜单中 VisualBasic 编辑器, 上 引用 并确保选中 Microsoft DAO 3.6 对象库 复选框。1. 在 MicrosoftAccess 中打开数据库。
2. 在数据库窗口, 单击下 对象 , 模块 , 然后单击 新建 。
3. 键入或粘贴以下代码, 您只有创建模块中:
代码如下:
Function RecoverDeletedTable()
On Error GoTo ExitHere
'*Declarations*
Dim db As DAO.Database
Dim strTableName As String
Dim strSQL As String
Dim intCount As Integer
Dim blnRestored As Boolean
'*Init*
Set db = CurrentDb()
'*Procedure*
For intCount = 0 To db.TableDefs.Count - 1
strTableName = db.TableDefs(intCount).Name
If Left(strTableName, 4) = "~tmp" Then
strSQL = "SELECT DISTINCTROW [" & strTableName & "].* INTO " & Mid(strTableName, 5) & " FROM [" & strTableName & "];"
DoCmd.SetWarnings False
DoCmd.RunSQL strSQL
MsgBox "A deleted table has been restored, using the name '" & Mid(strTableName, 5) & "'", vbOKOnly, "Restored"
blnRestored = True
End If
Next intCount
If blnRestored = False Then
MsgBox "No recoverable tables found", vbOKOnly
End If
'*EXIT/ERROR*
ExitHere:
DoCmd.SetWarnings True
Set db = Nothing
Exit Function
ErrorHandler:
MsgBox Err.Description
Resume ExitHere
End Function
4. 在 调试 菜单上, 单击 编译 数据库名称 数据库名称 。
5. 保存为 RecoverTable 模块。 要测试此函数, 首先创建两个表, 添加行, 并删除这两个表。
6. 在即时窗口, 键入以下行, 然后按 ENTER 键:

MySQL uses a GPL license. 1) The GPL license allows the free use, modification and distribution of MySQL, but the modified distribution must comply with GPL. 2) Commercial licenses can avoid public modifications and are suitable for commercial applications that require confidentiality.

The situations when choosing InnoDB instead of MyISAM include: 1) transaction support, 2) high concurrency environment, 3) high data consistency; conversely, the situation when choosing MyISAM includes: 1) mainly read operations, 2) no transaction support is required. InnoDB is suitable for applications that require high data consistency and transaction processing, such as e-commerce platforms, while MyISAM is suitable for read-intensive and transaction-free applications such as blog systems.

In MySQL, the function of foreign keys is to establish the relationship between tables and ensure the consistency and integrity of the data. Foreign keys maintain the effectiveness of data through reference integrity checks and cascading operations. Pay attention to performance optimization and avoid common errors when using them.

There are four main index types in MySQL: B-Tree index, hash index, full-text index and spatial index. 1.B-Tree index is suitable for range query, sorting and grouping, and is suitable for creation on the name column of the employees table. 2. Hash index is suitable for equivalent queries and is suitable for creation on the id column of the hash_table table of the MEMORY storage engine. 3. Full text index is used for text search, suitable for creation on the content column of the articles table. 4. Spatial index is used for geospatial query, suitable for creation on geom columns of locations table.

The main difference between MySQL and SQLite is the design concept and usage scenarios: 1. MySQL is suitable for large applications and enterprise-level solutions, supporting high performance and high concurrency; 2. SQLite is suitable for mobile applications and desktop software, lightweight and easy to embed.

Indexes in MySQL are an ordered structure of one or more columns in a database table, used to speed up data retrieval. 1) Indexes improve query speed by reducing the amount of scanned data. 2) B-Tree index uses a balanced tree structure, which is suitable for range query and sorting. 3) Use CREATEINDEX statements to create indexes, such as CREATEINDEXidx_customer_idONorders(customer_id). 4) Composite indexes can optimize multi-column queries, such as CREATEINDEXidx_customer_orderONorders(customer_id,order_date). 5) Use EXPLAIN to analyze query plans and avoid

Using transactions in MySQL ensures data consistency. 1) Start the transaction through STARTTRANSACTION, and then execute SQL operations and submit it with COMMIT or ROLLBACK. 2) Use SAVEPOINT to set a save point to allow partial rollback. 3) Performance optimization suggestions include shortening transaction time, avoiding large-scale queries and using isolation levels reasonably.
