Fix CI Failures

[nabdelgadir]

Description/Steps to reproduce

Currently there are five CI failures:

   1) juggler-v3
        datatypes
          "before all" hook for "should resolve top-level "type" property correctly":
      Error: ORA-00972: identifier is too long
   
 
   2) juggler-v3
        basic-querying
          "before all" hook in "basic-querying":
      Error: ORA-00955: name is already used by an existing object
   
 
   3) juggler-v3
        regexp operator
          "before all" hook: seed for "should return an error for invalid data types":
      Error: ORA-01400: cannot insert NULL into ("TEST"."USER"."ID")
   
 
   4) juggler-v4
        datatypes
          "before all" hook for "should resolve top-level "type" property correctly":
      Error: ORA-00972: identifier is too long
   
 
   5) juggler-v4
        basic-querying
          "before all" hook in "basic-querying":
      Error: ORA-00972: identifier is too long
   

The ORA-00972: identifier is too long error happens when an identifier is over 30 characters.

The failures are from the before hooks of the datatype.test.js and basic-querying.test.js files (not sure where regexp operator is from).

Acceptance Criteria

• Fix the errors so CI passes

As of Oracle DB 12.2 identifiers can be 128 characters. Do you need to test older DBs? Oracle 18 & 19 are also available - and there is a free Oracle XE 18 available.

Maybe check db versions and update Docker images.
and check sql statement in here and use debug string.
