MySQL数据库delete数据时不支持表别名
今天在帮同事查看一条删除的SQL语句执行出错的问题 SQL语句如下： DELETE FROM LEAD_SYSTEM_MENU_ORG_REF as t WHERE t.reso
今天在帮同事查看一条删除的SQL语句执行出错的问题
SQL语句如下：
DELETE FROM LEAD_SYSTEM_MENU_ORG_REF as t WHERE t.resourceid='4028812348f28b890148f29253a80000'
这条SQL语句放到Oracle数据库中去执行是可以正常执行的，但是放到MySQL数据库中执行时就出现了如下的错误：
[Err] 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE t.resourceid='4028812348f28b890148f29253a80000'
看到"SQL syntax"就知道SQL执行错误的原因是SQL语法不对，这就比较奇怪了，这条删除的SQL横看竖看都没有问题呀，Oracle能够正常执行，为什么MySQL却不行呢，上网查了一下原因，原来是MySQL数据库delete数据时，不支持表别名，这个问题以前也没有注意到，，在此记录一下。

Explain InnoDB Full-Text Search capabilities.
Apr 02, 2025 pm 06:09 PM
InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.
Difference between clustered index and non-clustered index (secondary index) in InnoDB.
Apr 02, 2025 pm 06:25 PM
The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.

The relationship between mysql user and database
Apr 08, 2025 pm 07:15 PM
In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.
