之前我知道有两种方法可以获取Mdb文件的所有表名:
1、调用TADOConnection::GetTableNames
2、查询系统表MSysObjects
但是实际中均遇到了问题,第1种方法会得到Access里表格连同查询的名字,而且没有办法区分;第二种方法MSysObjects默认是没有读写的权限的,需要修改Access文件的设置才行,这样如果是自己的数据库文件还好,如果是其它同事的数据库,要求别人也按照自己的想法来做总感觉不是很妥当,而且可能数据库文件在客户中已经开始使用导致没办法修改。
鉴于以上原因,我找了第三种方法。请看代码:
void GetMdbAllTables(TADOConnection *Conn, TStrings *List)
{
List->Clear();
AnsiString sTableType;
auto_ptr
query->Connection = Conn;
TSchemaInfo Schema = siTables;
Conn->OpenSchema( Schema, EmptyParam, EmptyParam, (TADODataSet*)query.get());
for ( ; !query->Eof; query->Next() )
{
sTableType = query->FieldByName("TABLE_TYPE")->AsString;
if ( sTableType == "TABLE" )
{
if ( !query->FieldByName("TABLE_NAME")->AsString.Pos("粘贴错误") ) //见注1
{
List->Add( query->FieldByName("TABLE_NAME")->AsString );
}
}
}
}
注1:/如果Access从外部导入表格,很可能会出现这个“粘贴错误”这个表名。

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA
