CI 链接mysql 和 mssql
由于要将mssql 和 mysql 里面的数据进行对比,So.
配置:database.php
<code>$db['default']['hostname'] = '192.168.1.222'; $db['default']['username'] = 'root'; $db['default']['password'] = 'test'; $db['default']['database'] = 'demo_database'; $db['default']['dbdriver'] = 'mysql'; $db['default']['dbprefix'] = 'iwebshop_'; $db['default']['pconnect'] = TRUE; $db['default']['db_debug'] = TRUE; $db['default']['cache_on'] = FALSE; $db['default']['cachedir'] = ''; $db['default']['char_set'] = 'utf8'; $db['default']['dbcollat'] = 'utf8_general_ci'; $db['default']['swap_pre'] = ''; $db['default']['autoinit'] = TRUE; $db['default']['stricton'] = FALSE; $db['default']['hostname'] = '192.168.1.222'; $db['default']['username'] = 'sa'; $db['default']['password'] = 'test'; $db['default']['database'] = 'demo_database'; $db['default']['dbdriver'] = 'sqlsrv'; $db['default']['dbprefix'] = ''; $db['default']['pconnect'] = TRUE; $db['default']['char_set'] = 'utf-8'; </code>
就是不知道怎么调用?

在model里调用例如 $db=$this->load->database('default',TRUE);
$db->query($sql);
你上面的配置文件是错误的,两个不同的数据库需要区分开,不能用相同的键名default,否则后面的配置会覆盖前面的配置的。上面的代码就是根据键名选择不同数据库的配置的。
$db1=$this->load->database('default',TRUE);
$db2=$this->load->database('another',TRUE);
调用多个数据库后不能再用$this->db->query($sql);
只能用$db1->query($sql);
默认的,你可以直接使用 $this->db 就可以使用了。
对于第二个,你需要在default的时候,换一个名称来标识是他们的配置,从而可以通过使用
$db2=$this->load->database('another',TRUE);
来调用

MySQL and phpMyAdmin can be effectively managed through the following steps: 1. Create and delete database: Just click in phpMyAdmin to complete. 2. Manage tables: You can create tables, modify structures, and add indexes. 3. Data operation: Supports inserting, updating, deleting data and executing SQL queries. 4. Import and export data: Supports SQL, CSV, XML and other formats. 5. Optimization and monitoring: Use the OPTIMIZETABLE command to optimize tables and use query analyzers and monitoring tools to solve performance problems.

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.

To safely and thoroughly uninstall MySQL and clean all residual files, follow the following steps: 1. Stop MySQL service; 2. Uninstall MySQL packages; 3. Clean configuration files and data directories; 4. Verify that the uninstallation is thorough.

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

Composer is a dependency management tool for PHP, and manages project dependencies through composer.json file. 1) parse composer.json to obtain dependency information; 2) parse dependencies to form a dependency tree; 3) download and install dependencies from Packagist to the vendor directory; 4) generate composer.lock file to lock the dependency version to ensure team consistency and project maintainability.

Installing MySQL on macOS can be achieved through the following steps: 1. Install Homebrew, using the command /bin/bash-c"$(curl-fsSLhttps://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)". 2. Update Homebrew and use brewupdate. 3.
