How to do a LIKE query in SQLite (in Javascript) whilst passing in the search term as a parameter

问题

I am using React Native and am querying a SQLite database.

I wish to perform a like query, specifying the search term as a parameter.

The below works fine with the ? notation.

SELECT * from People WHERE Name = ?

This does not work or any similar variation I've tried:

SELECT * from People WHERE Name LIKE '%?%' 

Anyone know how to do this properly please? Please no interpolations or suggestions open to SQL injection.

You can do string concatenation in SQLite:

SELECT * from People WHERE Name LIKE '%' || ? || '%' 

Another option is to concatenate the percent marks with the parameter in your javascript code before passing it to the query, so you can then do:

SELECT * from People WHERE Name LIKE ?
