(that works on any database) Second question , none of the tutorial I've read mention about LIKE statement, how to bind arguments

问题 I'm trying to build a prepared statement with wildcards however I'm running into an issue where the percentage wildcard characters seem to be returning what seem to be hashes for the wildcards and I'm not sure why. The code in question is: $condition = $wpdb->prefix."posts.post_title LIKE %%%s%%"; $query['conditions'][] = $wpdb->prepare($condition, $name); And the results are: posts.post_title LIKE {d690dd63f5944b9bca120e110c22802f0ec841d8120d813dd4abc08cba4a59c0}BT

Multiple Prepared statements in PHP with MySQLi

喜夏-厌秋 提交于 2020-05-08 09:21:26
问题 I want to do two prepared statements, one right after the other in PHP with MySQLi. I am a novice at PHP and MySQLi so I don't know whether I should close the statement, close the database connection, put all of the code in a function, or just have code not inside a function. Basically I just want to insert a record into one table and then insert the same record into another table using MySQLi. Thanks! 回答1: Directly off the mysqli page: http://php.net/manual/en/mysqli.commit.php <?PHP mysqli

If my SQL statement is only evaluated once, then why would I use sqlite3_bind()?

问题 For example, the first comment on the question How to properly escape single quotes in SQLite insert statement - iOS says "Don't use stringWithFormat to build your query. Do it properly with sqlite3_bind_xxx statements." I've seen (on Stack Overflow and beyond) many comments/answers like this that unconditionally suggest using parameters instead of literals. However, I don't see any suggestions like that on the SQLite website. I do see that section "6. Binding Parameters and Reusing Prepared

问题 I'm using ODBC (Win32) to connect to our Pervasive SQL database. I have post variables that I need to insert into SQL queries and later extract individual rows.
