Illegal Variable Name/Number when Passing in Python List

December 7, 2021

I’m trying to run SQL statements through Python on a list.
By passing in a list, in this case date. Since i want to run multiple SELECT SQL queries and return them.
I’ve tested this by passing in integers, however when trying to pass in a date I am getting ORA-01036 error. Illegal variable name/number. I’m using an Oracle DB.

cursor = connection.cursor()
date = ["'01-DEC-21'", "'02-DEC-21'"]

sql = "select * from table1 where datestamp = :date"

for item in date:
    cursor.execute(sql,id=item)
    res=cursor.fetchall()
    print(res)

Any suggestions to make this run?

>Solution :

You can’t name a bind variable date, it’s an illegal name. Also your named variable in cursor.execute should match the bind variable name. Try something like:

sql = "select * from table1 where datestamp = :date_input"

for item in date:
  cursor.execute(sql,date_input=item)
  res=cursor.fetchall()
  print(res)
