sql yii debug

这篇文章主要介绍了Yii调试SQL的常用方法,需要的朋友可以参考下

Yii调试SQL主要有以下方法:

一、系统自带调试:

首先index.php开启调试模式:

// remove the following lines when in production mode defined('YII_DEBUG') or define('YII_DEBUG',true); // specify how many levels of call stack should be shown in each log message defined('YII_TRACE_LEVEL') or define('YII_TRACE_LEVEL',3); //app use time //defined('YII_BEGIN_TIME') or define('YII_BEGIN_TIME',microtime(true));

main.php页面:

'errorHandler'=>array( // use 'site/error' action to display errors 'errorAction'=>'site/error', ), 'log'=>array( 'class'=>'CLogRouter', 'routes'=>array( array( 'class'=>'CFileLogRoute', 'levels'=>'error, warning', ), // 下面显示页面日志 array( 'class'=>'CWebLogRoute', 'levels'=>'trace',   //级别为trace 'categories'=>'system.db.*' //只显示关于数据库信息,包括数据库连接,数据库执行语句 ), ), ),

YII_TRACE_LEVEL的数字越大,信息越清楚

二、使用调试工具调试:

yii-debug-toolbar把包解压后 放到extensions里边 然后在配置文件main.php中最后加上

'log'=>array( 'class'=>'CLogRouter', 'routes'=>array( array( 'class'=>'ext.yii-debug-toolbar.YiiDebugToolbarRoute', 'ipFilters'=>array('127.0.0.1','192.168.1.215'), ), ), ),

没有出现的话加上在'components'下的db里加上两个属性,

'enableProfiling'=>true, 'enableParamLogging'=>true,

然后如果有其他调试工具的插件的话,可能会出现冲突导致sql语句不出来,,把那段代码注掉即可。

How to use LeakSanitizer to debug C++ memory leaks? How to use LeakSanitizer to debug C++ memory leaks? Jun 02, 2024 pm 09:46 PM

How to use LeakSanitizer to debug C++ memory leaks? Install LeakSanitizer. Enable LeakSanitizer via compile flag. Run the application and analyze the LeakSanitizer report. Identify memory allocation types and allocation locations. Fix memory leaks and ensure all dynamically allocated memory is released.

How to conduct concurrency testing and debugging in Java concurrent programming? How to conduct concurrency testing and debugging in Java concurrent programming? May 09, 2024 am 09:33 AM

Concurrency testing and debugging Concurrency testing and debugging in Java concurrent programming are crucial and the following techniques are available: Concurrency testing: Unit testing: Isolate and test a single concurrent task. Integration testing: testing the interaction between multiple concurrent tasks. Load testing: Evaluate an application's performance and scalability under heavy load. Concurrency Debugging: Breakpoints: Pause thread execution and inspect variables or execute code. Logging: Record thread events and status. Stack trace: Identify the source of the exception. Visualization tools: Monitor thread activity and resource usage.

Shortcut to golang function debugging and analysis Shortcut to golang function debugging and analysis May 06, 2024 pm 10:42 PM

This article introduces shortcuts for Go function debugging and analysis, including: built-in debugger dlv, which is used to pause execution, check variables, and set breakpoints. Logging, use the log package to record messages and view them during debugging. The performance analysis tool pprof generates call graphs and analyzes performance, and uses gotoolpprof to analyze data. Practical case: Analyze memory leaks through pprof and generate a call graph to display the functions that cause leaks.

How to debug PHP asynchronous code How to debug PHP asynchronous code May 31, 2024 am 09:08 AM

Tools for debugging PHP asynchronous code include: Psalm: a static analysis tool that can find potential errors. ParallelLint: A tool that inspects asynchronous code and provides recommendations. Xdebug: An extension for debugging PHP applications by enabling a session and stepping through the code. Other tips include using logging, assertions, running code locally, and writing unit tests.

PHP Debugging Errors: A Guide to Common Mistakes PHP Debugging Errors: A Guide to Common Mistakes Jun 05, 2024 pm 03:18 PM

Common PHP debugging errors include: Syntax errors: Check the code syntax to make sure there are no errors. Undefined variable: Before using a variable, make sure it is initialized and assigned a value. Missing semicolons: Add semicolons to all code blocks. Function is undefined: Check that the function name is spelled correctly and make sure the correct file or PHP extension is loaded.

Traps and avoidance of golang function debugging and analysis tools Traps and avoidance of golang function debugging and analysis tools May 06, 2024 pm 03:21 PM

Pitfalls and Avoidances of Go Function Debugging and Analysis Tools When debugging and analyzing Go applications, there are many useful tools available, such as: pprof, gotrace, and gotooltrace. However, there are pitfalls in the use of these tools that need to be recognized and avoided to obtain the most accurate and useful results. The pprof trap sampling rate is improperly set: a sampling rate that is too high may cause application performance degradation, while a sampling rate that is too low may miss important information. Function inlining is not disabled: Function inlining can reduce sampling accuracy, resulting in a lack of visibility into internal function calls. Inlining can be disabled using the -noinlining flag. Insufficient sampling time: give pprof sufficient time to collect

How to debug deadlocks in C++ programs? How to debug deadlocks in C++ programs? Jun 03, 2024 pm 05:24 PM

Deadlock is a common error in concurrent programming that occurs when multiple threads wait for locks held by each other. Deadlocks can be resolved by detecting them using a debugger, analyzing thread activity, and identifying the threads and locks involved. Ways to resolve deadlocks include avoiding circular dependencies, using deadlock detectors, and using timeouts. In practice, deadlocks can be avoided by ensuring that threads acquire locks in the same order or by using recursive locks or condition variables.
