Dates in Oracle
Advise, please on comparing dates in Oracle SQL. Previously operational code:

(accs.EVENT_DT>'5/18/1992')

now throws this error:

ERROR: ORA-01843: not a valid month

accs.EVENT_DT is a field of type DATE and SQL-Plus displays it like 10-Sep-03

I'm thinking that I need to express the date to which I want to compare accs.EVENT_DT properly. That is to say I need to convert 5/18/1992 (in this example) to a properly formated date expression.

Any ideas?

I'm not an oracle expert, but sql server has a function called CAST() which you could use to force your char data to datetime. You might look at your oracle docs to see if there is something similar.

Could also be that your ORA is configured for a date format other than mm/dd/yyyy

it's sure that your oracle is set to the format dd/mm/yyyy

Prove to use (accs.EVENT_DT>to_date('05/18/1992','mm/dd/yyyy')
