php环境下的sql语句，看不懂, 这是什么意思？
$query_Recordset1 = sprintf("SELECT * FROM tk_user WHERE tk_user_status LIKE %s AND tk_user_status NOT LIKE %s AND tk_display_name LIKE %s ORDER BY tk_user_registered DESC", ....
是做了什么操作？“tk_user_status LIKE %s AND tk_user_status NOT LIKE %s”不是矛盾了么？但是程序正常运行没问题啊!
------解决方案--------------------
这有什么不对吗？ 三个字符串填充三个占位符。
------解决方案--------------------
这不矛盾啊！tk_user_status LIKE %s AND tk_user_status NOT LIKE %s
前面一个%s和后面的%s是不一样的变量，下面就是传入的参数变量
GetSQLValueString("%" . $colrole_Recordset1 . "%", "text"),
GetSQLValueString("%" . $colrole_dis . "%", "text"),

What is the difference between MySQL's REGEXP and LIKE?
May 30, 2023 pm 01:58 PM
1. The difference in matching content. LIKE requires that the entire data must be matched. With Like, all the contents of this field must meet the conditions; REGEXP only requires partial matching, and only one fragment needs to be satisfied. 2. Differences in matching positions: LIKE matches the entire column. If the matched text appears in the column value, LIKE will not find it and the corresponding row will not be returned (unless wildcards are used); REGEXP is within the column value. A match is performed. If the matched text appears in the column value, REGEXP will find it, the corresponding row will be returned, and REGEXP can match the entire column value (same effect as LIKE). 3. The SQL statement returns data that differs from LIKE matching: the SQL statement
How to solve the problem of docker mounting directory permissions
Feb 29, 2024 am 10:04 AM
In Docker, the permission problem of the mounting directory can usually be solved by the following method: adding permission-related options when using the -v parameter to specify the mounting directory. You can specify the permissions of the mounted directory by adding: ro or :rw after the mounted directory, indicating read-only and read-write permissions respectively. For example: dockerrun-v/host/path:/container/path:roimage_name Define the USER directive in the Dockerfile to specify the user running in the container to ensure that operations inside the container comply with permission requirements. For example: FROMimage_name#CreateanewuserRUNuseradd-ms/bin/
How to use the mysql database LIKE operator in python
May 31, 2023 pm 09:46 PM
The LIKE operator is used to search for a specified pattern in a column in the WHERE clause. Syntax: SELECTcolumn_name(s)FROMtable_nameWHEREcolumn_nameLIKEpatternpattern This is where the specified template is placed, and "%" is used here, also called the wildcard character %. If it is placed in front of the condition, it will search for data ending with...; for example: % If Li % is placed after the condition, then the data starting with... is searched; for example: Li %% exists before and after the condition, then the included data is searched; for example: % Li % Little knowledge point: ERROR1064 (42000):Youhaveane
How to use Union to optimize Like statement in MySQL
May 31, 2023 pm 03:55 PM
Optimize the Like statement with Union 1) Sometimes, you may need to use the or operator for comparison in the query. When the or keyword is used too frequently in the where clause, it may cause the MySQL optimizer to mistakenly choose a full table scan to retrieve records. The union clause can make queries execute faster, especially when one of the queries has an optimized index and the other query also has an optimized index. For example, when there are indexes on first_name and last_name respectively, execute the following query statement: mysql>select*fromstudentswherefirst_namelike'A
