qt4连接mysql

运行平台：win7

编译器：vc

IDE：vs2010

MYSQL：5.5

怕自己忘了，也留作别人的参考

mysql所对应的dll和lib是qsqlmysqld4.dll和qsqlmysqld4.lib。这是由编译得来的。

1)首先进入cd %QTDIR%/src/plugins/sqldrivers/mysql目录，

2)运行命令qmake -o Makefile "INCLUDEPATH+=C:/MySQL/include" "LIBS+=C:/MySQL/lib/opt/libmysql.lib" mysql.pro，这里的C:/MySQL是mysql的安装目录，这里面不能有空格，如果有空格则无法编译通过，这时候，就必须把mysql安装目录下的include和lib复制到另外一个没有空格的目录中，比如我就复制到D:/work中，那么上面这条命令变成了

qmake -o Makefile "INCLUDEPATH+=D:/work/include" "LIBS+=D:/work/lib/libmysql.lib" mysql.pro

3)运行nmake，这时候在%QTDIR%/src/plugins/sqldrivers/mysql/debug下面就出现了所需的文件qsqlmysqld4.dll和qsqlmysqld4.lib

4)把这两个文件复制到%QTDIR%/plugins/sqldrivers下面

MySQL BLOB: how to optimize BLOBs requestsMay 13, 2025 am 12:03 AM

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

MySQL: String Data Types and Indexing: Best PracticesMay 12, 2025 am 12:11 AM

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.
