Oracle returns CASCADE=0, SET_NULL=2, and NO_ACTION=1 `decode (f.delete_rule, 'CASCADE', 0, 'SET NULL', 2, 1) as delete_rule` So when it returns 1, which in the current code corresponds to DatabaseMetaData.importedKeyRestrict, it will now be mapped to NO_ACTION because Oracle does not have the RESTRICT reference option. NO_ACTION behaves likes RESTRICT for it.

) Oracle returns CASCADE=0, SET_NULL=2, and NO_ACTION=1 `decode (f.delete_rule, 'CASCADE', 0, 'SET NULL', 2, 1) as delete_rule` So when it returns 1, which in the current code corresponds to DatabaseMetaData.importedKeyRestrict, it is mapped to RESTRICT, which is not supported in Oracle. Instead of that, it will now be mapped to NO_ACTION. The resolveRefOptionFromJdbc function was moved from Constraints.kt to DatabaseDialect.kt.
