问题描述:
工作中总会时不时地遇到一些这样的情况,在开发或者QA上程序运行总是好好的,但到了生产环境,程序却跑不出来了。印象比较深刻的是之前遇到的两个以sql server为数据库的网页项目,一是访问网页错误,二是网页上的下拉列表没有结果。
环境:SQL SERVER 2008, IIS, SSRS 2008, Visual Studio 2008, ASP.NET
解决方法:
第一种情况:
将网页发布到生产环境之后,,系统会检测你个人的系统登陆账号是否有权限访问该网页,该权限控制是配置在数据库里面几张表里面的。某同学在为自己和小伙伴们配置好了权限之后,发现在登陆生产环境还是会出错。而实际情况是,该同学忽略了IIS里面的application pool identity账户。在asp.net debug模式下,内置的网页服务器使用自己的系统帐号去访问数据库。可网页一旦发布到某IIS服务器上之后,还需要将数据库的访问权限赋予IIS里面配置的application pool identity账户。(当然还要将该IIS的Web Site的访问权限赋予自己的系统登陆账号)
第二种情况:
没有把下拉列表所使用的procedure execute权限赋予访问组。 语法:GRANT EXECUTE ON procedure_nm TO PUBLIC

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.

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.

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.

Use the EXPLAIN command to analyze the execution plan of MySQL queries. 1. The EXPLAIN command displays the execution plan of the query to help find performance bottlenecks. 2. The execution plan includes fields such as id, select_type, table, type, possible_keys, key, key_len, ref, rows and Extra. 3. According to the execution plan, you can optimize queries by adding indexes, avoiding full table scans, optimizing JOIN operations, and using overlay indexes.

Subqueries can improve the efficiency of MySQL query. 1) Subquery simplifies complex query logic, such as filtering data and calculating aggregated values. 2) MySQL optimizer may convert subqueries to JOIN operations to improve performance. 3) Using EXISTS instead of IN can avoid multiple rows returning errors. 4) Optimization strategies include avoiding related subqueries, using EXISTS, index optimization, and avoiding subquery nesting.

Methods for configuring character sets and collations in MySQL include: 1. Setting the character sets and collations at the server level: SETNAMES'utf8'; SETCHARACTERSETutf8; SETCOLLATION_CONNECTION='utf8_general_ci'; 2. Create a database that uses specific character sets and collations: CREATEDATABASEexample_dbCHARACTERSETutf8COLLATEutf8_general_ci; 3. Specify character sets and collations when creating a table: CREATETABLEexample_table(idINT

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.

Renaming a database in MySQL requires indirect methods. The steps are as follows: 1. Create a new database; 2. Use mysqldump to export the old database; 3. Import the data into the new database; 4. Delete the old database.
