[cx-oracle-users] cx_Oracle "Expecting None or a String"

[Anurag C. <anu...@gm...>]

All,

I am on the following cx_Oracle version

>>> cx_Oracle.version
'5.0.3'

Time and again I get this error in executing a query

expecting None or a string

The query is being executed this way

cursor.execute("SELECT * FROM APP_STORE WHERE STORE=:STORE %s"
%(order_clause),{'STORE':STORE})

What could be the reason? Similar queries executed earlier in the flow work
fine but this one does not.

Appreciate some guidance on this.

Regards,
Anurag
