I would recommend enabling MySQL query log on your server if you have access to see exactly what the query looks like to MySQL so you can be sure that MySQL is getting a valid query. The index of NULL is NULL. However, if MySQL data disk is damaged, we need to recover the database from the latest full-backup and binary log (hopefully not damaged), a straight backup/recovery policy is needed. You can use the following method to escape the quotes: statement = """ Update chats set html='{}' """.format(html_string.replace("'","\\\'")) Note: three \ characters are needed to escape the single quote which is there in unformatted python string. The default collation for latin1 is latin1_swdish_ci, which is a case-insensitive collation suitable for Swedish/finnish (MySQL was created by some Swedishs). PHP 5.4 - Changed the default value Example (Testing the Integer Data Types): Read "integer_arena.sql". In these cases using double quotes to wrap a text string that contains a contraction like Theyve will keep the single quote in the string as an apostrophe. "it threw me some errors" -- What were these errors? In MySQL, columns, tables, databases may use different character sets. System Variables: MySQL server maintains system variables, grouped in two categories: global and session. When QUOTED_IDENTIFIER is set to OFF, the strings can be enclosed in double quotes. I strongly recommend using UTF8 character set for MySQL columns that require internationalization support. In other words, they will be processed by MySQL but treated as comments by other databases. It generates a text file of SQL statements that can later be executed to recreate the database/table and its contents. All stored objects for a database are removed, when the database is dropped. To take a full backup, run mysqldump with these options: To take an incremental-backup, issue command ".
