Using a WHERE ___ IN ___ statement
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.
FYI, pymysql with MySQL user.
query ="SELECT * FROM tab WHERE obj IN %s"cursor.execute(query, (['foo','bar'],))same ascursor.execute(query, (list_of_var,))
I'm not sure about sqlite3,this may work,
query ="SELECT * FROM tab WHERE obj IN ?"cursor.execute(query, (['foo','bar'],)) orcursor.execute(query, (list_of_vars,))
