Warning

Avoid using the LONG and LONG RAW data types.

Rule Details

Severity Level: Major
Quality Area: Maintainability
Fixing times: 5 mins
Local-medium
Database Support: OracleDB (v8.1.5 +)

Reason

long and long raw data types have been deprecated by the Oracle Database since version 8i and provided for backward compatibility only.

There are many constraints to long datatypes in comparison to the lob types. Oracle strongly recommends to use lob instead of long data types.

Example

Non-Compliant Example

declare
   l_long long;
   l_raw  long raw;
begin
   do_something(l_long);
   do_something(l_raw);
end;
/
