Python SQLite SELECT LIKE IN [list]

How to write SQL query in Python to select elements LIKE IN Python list?

For example, I have Python list of strings

Names=['name_1','name_2',..., 'name_n']

and SQLite_table.

My task is to find shortest way to

SELECT elements FROM SQLite_table WHERE element_name LIKE '%name_1%'
SELECT elements FROM SQLite_table WHERE element_name LIKE '%name_2%'
...
SELECT elements FROM SQLite_table WHERE element_name LIKE '%name_n%'

You would need a regular expression of the form name_1|name_2|name_3|…, which you can generate using '|'.join(Names):

SELECT elements FROM SQLite_table WHERE element_name REGEXP 'name_1|name_2|name_3|…|name_n'

Check How do I use regex in a SQLite query? for instructions on how to use regular expressions in SQLite.

Mmhh

Names=['name_1','name_2','name_n']
for i in Names:
    sql = "SELECT elements FROM SQLite_table WHERE element_name LIKE '%" + i + "%'" 
    print sql

SELECT elements FROM SQLite_table WHERE element_name LIKE '%name_1%'
SELECT elements FROM SQLite_table WHERE element_name LIKE '%name_2%'
SELECT elements FROM SQLite_table WHERE element_name LIKE '%name_n%'
