python - SQLite execute statement for variable-length rows -


i've read advice here using parametrized execute call sql escaping you, seems work when know number of columns in advance.

i'm looping on csv files, 1 each table, , populating local db testing purposes. each table has different numbers of columns, can't use:

sql = "insert table_a values (%s, %s)" cursor.execute(sql, (val1, val2))

i can build sql statement string quite flexibly, doesn't give me use of cursor.execute's sql-escaping facilities, if input contains apostrophes or similar, fails.

it seems there should simple way this. there?

if know number of parameters, can create list of them:

count = ... sql = "insert ... values(" + ",".join(count * ["?"]) + ")" params = [] in ...:     params += ['whatever'] cursor.execute(sql, params)
