Question

Migrating to AddDeviseToUsers (20140704194919)

== 20140704194919 AddDeviseToUsers：迁移 =================================

-- change_table(:users) (36.9ms) ALTER TABLE "RA_USERS" ADD "EMAIL" VARCHAR2(255) DEFAULT '' NOT NULL OCIError: ORA-00600: 内部错误代码，参数：[kkdlSetColDTypeDfltProps0], [], [], [], [], [], [], []: ALTER TABLE

"RA_USERS" 添加 "EMAIL" VARCHAR2(255) DEFAULT '' NOT NULL 耙子中止了！

StandardError：发生错误，所有后续迁移都已取消：

OCIError: ORA-00600: 内部错误代码，参数：[kkdlSetColDTypeDfltProps0], [], [], [], [], [], [], []: ALTER TABLE "RA_USERS" ADD "EMAIL" VARCHAR2 (255) DEFAULT '' NOT NULLstmt.c:230:in oci8lib_210.so

数据库是Oracle 从来没有遇到过这个问题，可能是我需要解决的数据库锁定问题或其他问题？

Answer 1

我发现它无法将非空列添加到已经包含数据的表中。 Oracle 这样做是为了保持数据库的完整性。
