ORA-00932
ORA-00932:inconsistent datatypes: expected string got string
Cause:One of the following:

  • An attempt was made to perform an operation on incompatible datatypes. For example, adding a character field to a date field (dates may only be added to numeric fields) or concatenating a character field with a long field.
  • An attempt was made to perform an operation on a database object (such as a table or view) that is not intended for normal use. For example, system tables cannot be modified by a user. Note that on rare occasions this error occurs because a misspelled object name matched a restricted object's name.
  • An attempt was made to use an undocumented view.
Action:If the cause is

  • different datatypes, then use consistent datatypes. For example, convert the character field to a numeric field with the TO_NUMBER function before adding it to the date field. Functions may not be used with long fields.
  • an object not intended for normal use, then do not access the restricted object.

I was told there would be no (date) math

Hey all While debugging an analytical function issue using 9.2.0.5 I run this idiotic query SELECT TRUNC(SYSDATE) - TRUNC(SYSDATE) - TRUNC(SYSDATE) FROM DUAL And it errors out with ORA-00932
