MySQL php get column using another column (Get password using username)

由 我只是一个虾纸丫 提交于 2021-02-07 21:33:08
问题 After successfully verifying username exists in the database, I need to verify whether the password matches as well. Therefore, I need to retrieve the hashed password from the database, right? Or do I have other choices? I'm using PHP 5.5 API bcrypt for hashing. My code would give me a 500 internal server error when I get the password from database. How do I do this correctly? Here's my php code: // If found username, check password, else respond invalid username if($countRows!==0){ // Get

MySQL duplicate key error causes a shared lock set on the duplicate index record?

由 瘦欲@ 提交于 2021-02-07 20:52:43
问题 I've read the document of MySQL 14.2.7.6. Locks Set by Different SQL Statements in InnoDB http://dev.mysql.com/doc/refman/5.0/en/innodb-locks-set.html My questions: I don't understand why documentation states: If a duplicate-key error occurs, a shared lock on the duplicate index record is set. This use of a shared lock can result in deadlock should there be multiple sessions trying to insert the same row if another session already has an exclusive lock. This can occur if another session

问题 I am working on a C# project and I am facing an issue. The program allows the user to connect to a MySQL database and retrieve information from each selected table and write the data out to a file.

If the timestamp column contains the date 0000-00-00 00:00:00 I get the conversion error and no matter what I try it never works. I've tried converting to a string I've tried converting to
