Hello, I'm trying to use psycopg2 to create tables in a database using: run = "S90040" curs.execute("create table %s (date text, tset text)",(run,)) but it fails with Traceback (most recent call last): File "write_xy_to_pg_psyco.py", line 44, in ? curs.execute("create table %s (date text, tset text)",(run,)) psycopg2.ProgrammingError: syntax error at or near "'S90040'" at character 14 If I run curs.execute("create table S90040 (date text, tset text)",(run,)) it works perfectly, so I assume the quoting is messed up. Could someone please tell me what I'm doing wrong? Thanks, Roger Mason
