clang编译mysql(Ubuntu10 64位)_MySQL
Ubuntu
bitsCN.com编译安装mysql(Ubuntu10 64位) http://www.cnblogs.com/2018/p/3482259.html 这个介绍了gcc形式编译安装mysql
那我们使用clang进行编译一下看看具体的效果
编译安装mysql(Ubuntu10 64位) 已经描述了mysql的编译安装情况,由于clang的性能比较高,现在实验一下mysql的clang编译
经试验,主要解决如下的问题即可
v ABI_CHECK
n 这个问题表现是配置完成后,编译时会出现ABI的报错,google了一下,由于官方没有直接clang的支持,因此可以忽略,网上有人这样用过
v Clang编译器的引入
n 或者在cmake的配置文件修改,或者使用环境变量进入,使用一个简单的形式如下,引入clang编译器即可
export CXX=clang++
export CC=clang
最初我看了一下clang++连接到的就是clang,因此我想当然的认为直接都设置为clang就行,不过编译会出错提示AES undefined reference operator delete(void*),具体看了一下原因,如下的地址
clang vs calng++

如上处理就可以了编译和安装了,具体的脚本如下:
if [ -d mysql-5.6.15 ]; then
echo "mysql代码已经存在了"
else
tar xzf mysql-5.6.15.tar.gz
fi
#cmake/abi_check.cmake ABI检查的问题,可以跳过
# LINE30 SET(RUN_ABI_CHECK 0)
cp -f abi_check.cmake mysql-5.6.15/cmake/abi_check.cmake
mkdir -p build
pushd build
if [ -f CMakeCache.txt ]; then
make clean
rm -f CMakeCache.txt
fi
#使用clang编译
export CXX=clang++
export CC=clang
#编译时看看是否启用了clang

if [ $? -ne 0 ];
then
echo -e "/e[1;41m cmake's config error! /e[0m"
exit 1

make
if [ $? -ne 0 ];
then
echo -e "/e[1;41m cmake done! /e[0m"
exit 1
fi
popd
echo "The package is in build directory!"

Big data structure processing skills: Chunking: Break down the data set and process it in chunks to reduce memory consumption. Generator: Generate data items one by one without loading the entire data set, suitable for unlimited data sets. Streaming: Read files or query results line by line, suitable for large files or remote data. External storage: For very large data sets, store the data in a database or NoSQL.

MySQL query performance can be optimized by building indexes that reduce lookup time from linear complexity to logarithmic complexity. Use PreparedStatements to prevent SQL injection and improve query performance. Limit query results and reduce the amount of data processed by the server. Optimize join queries, including using appropriate join types, creating indexes, and considering using subqueries. Analyze queries to identify bottlenecks; use caching to reduce database load; optimize PHP code to minimize overhead.

Backing up and restoring a MySQL database in PHP can be achieved by following these steps: Back up the database: Use the mysqldump command to dump the database into a SQL file. Restore database: Use the mysql command to restore the database from SQL files.

How to insert data into MySQL table? Connect to the database: Use mysqli to establish a connection to the database. Prepare the SQL query: Write an INSERT statement to specify the columns and values to be inserted. Execute query: Use the query() method to execute the insertion query. If successful, a confirmation message will be output.

One of the major changes introduced in MySQL 8.4 (the latest LTS release as of 2024) is that the "MySQL Native Password" plugin is no longer enabled by default. Further, MySQL 9.0 removes this plugin completely. This change affects PHP and other app

To use MySQL stored procedures in PHP: Use PDO or the MySQLi extension to connect to a MySQL database. Prepare the statement to call the stored procedure. Execute the stored procedure. Process the result set (if the stored procedure returns results). Close the database connection.

Creating a MySQL table using PHP requires the following steps: Connect to the database. Create the database if it does not exist. Select a database. Create table. Execute the query. Close the connection.

Oracle database and MySQL are both databases based on the relational model, but Oracle is superior in terms of compatibility, scalability, data types and security; while MySQL focuses on speed and flexibility and is more suitable for small to medium-sized data sets. . ① Oracle provides a wide range of data types, ② provides advanced security features, ③ is suitable for enterprise-level applications; ① MySQL supports NoSQL data types, ② has fewer security measures, and ③ is suitable for small to medium-sized applications.
