How to Convert a MySQL Dump File to SQLite: A Step-by-Step Guide with Shell Script Examples

Importing MySQL Dump File into SQLite Database

Converting a MySQL dump SQL file into a format suitable for importing into a SQLite database can be a multifaceted task. However, a shell script can effectively accomplish this conversion.

The provided script filters unwanted lines, removes unnecessary constraints, and transforms data types to be compatible with SQLite. Here's a breakdown of its operations:

• grep commands exclude lines containing unique constraints and auto-increment values, ensuring compatibility with SQLite.
• sed commands perform various transformations, including removing "unsigned" attributes, converting smallint and tinyint to integer, and eliminating character sets.
• perl commands merge multi-line INSERT statements and escape single quotes for proper import.
• The sqlite3 command imports the converted SQL file into a new SQLite database.

By running the provided script on the MySQL dump file (replacing with the file name), you can effectively convert it to a format that can be imported into SQLite. The $1.db file will contain the converted database, while $1.err will log any potential conversion errors.
