【MySQL案例】ERROR1786(HY000)_MySQL
1.1.1. ERROR 1786 (HY000)
【环境描述】
msyql5.6.14
【报错信息】
执行create table ... select的时候遇到报错:
db1 [test] [23:01:58]> create tablelgmnr_bak select * from lgmnr;
ERROR 1786 (HY000): CREATE TABLE ... SELECTis forbidden when @@GLOBAL.ENFORCE_GTID_CONSISTENCY = 1
【报错原因】
ERROR1786是由于开启了enforce_gtid_consistency=true功能导致的,MySQL官方解释说当启用enforce_gtid_consistency功能的时候,MySQL只允许能够保障事务安全,并且能够被日志记录的SQL语句被执行,像create table ... select 和 create temporarytable语句,以及同时更新事务表和非事务表的SQL语句或事务都不允许执行。
db1 [test] [23:28:28]> show variableslike 'ENFORCE_GTID_CONSISTENCY';
+--------------------------+-------+
| Variable_name | Value |
+--------------------------+-------+
| enforce_gtid_consistency | ON |
+--------------------------+-------+
【解决方法】
由于enforce_gtid_consistency参数是只读的,所以必须重启MySQL服务才能是配置生效。
尝试在线动态修改时的报错:
db1 [test] [23:37:56]> set globalenforce_gtid_consistency=true;
ERROR 1238 (HY000): Variable'enforce_gtid_consistency' is a read only variable

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.

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

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.

Article discusses strategies for handling large datasets in MySQL, including partitioning, sharding, indexing, and query optimization.

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.
