Using a WHERE ___ IN ___ statement

Solution 1:

You need to create enough parameters to match your list of vars:

statement = "SELECT * FROM tab WHERE obj IN ({0})".format(', '.join(['?'] * len(list_of_vars)))
c.execute(statement, list_of_vars)

Note that you pass in list_of_vars as the parameter values list. Using the ', '.join() we generate a string of ? characters separated by commas, then use .format() to insert that into the statement.

For a long list of variables, it may be more efficient to use a temporary table to hold those values, then use a JOIN against the temporary table rather than an IN clause with bind parameters.
