前言

通过 YMP 迁移 Oracle 到 YashanDB 对象后，YMP 已经提供了校验功能，推荐使用 YMP 的校验功能。如果需要更复杂的对比方法，可采用本文中的对比思路和方法。

思路

保存 Oracle 的 DBA_*数据字典视图到某用户的表，然后通过 YMP 传到 YashanDB，最后使用 YashanDB 的 DBeaver 图形界面通过 SQL 来查询不一致。

方法

1、在 Oracle 执行，保存 Oracle 的 DBA_*数据字典视图到 Oracle 用户的表

create user oracle identified by welcome1;
grant dba, resource, connect to oracle;
 
create table oracle.dba_objects as select * from sys.dba_objects;
create table oracle.dba_tables as select * from sys.dba_tables;
create table oracle.dba_indexes as select * from sys.dba_indexes;
create table oracle.dba_ind_columns as SELECT INDEX_OWNER, INDEX_NAME, TABLE_OWNER, TABLE_NAME, COLUMN_NAME, COLUMN_POSITION, COLUMN_LENGTH, DESCEND FROM SYS.DBA_IND_COLUMNS;
create table oracle.dba_constraints as SELECT OWNER, CONSTRAINT_NAME, CONSTRAINT_TYPE, TABLE_NAME, INDEX_NAME, INDEX_OWNER, R_OWNER, R_CONSTRAINT_NAME, DELETE_RULE, STATUS, DEFERRABLE, DEFERRED, VALIDATED, GENERATED FROM SYS.DBA_CONSTRAINTS;
create table oracle.dba_cons_columns as SELECT OWNER, CONSTRAINT_NAME, TABLE_NAME, COLUMN_NAME, POSITION FROM SYS.DBA_CONS_COLUMNS;
 
create table oracle.dba_types as select * from sys.dba_types;
create table oracle.dba_views as SELECT OWNER, VIEW_NAME, TEXT_LENGTH, TEXT_VC FROM SYS.DBA_VIEWS;
create table oracle.dba_sequences as select * from sys.dba_sequences;
create table oracle.dba_source as select * from sys.dba_source;
create table oracle.dba_triggers as SELECT OWNER, TRIGGER_NAME, TRIGGER_TYPE, TRIGGERING_EVENT, TABLE_OWNER, BASE_OBJECT_TYPE, TABLE_NAME, COLUMN_NAME, REFERENCING_NAMES, WHEN_CLAUSE, STATUS, DESCRIPTION, ACTION_TYPE FROM SYS.DBA_TRIGGERS;

复制代码

2、通过 YMP 将 Oracle 用户下的第一步保存的数据字典信息表同步到 YashanDB 数据库的 Oracle 用户

3、在 YashanDB 执行，保存 SYS 的 DBA_*数据字典视图到 Yashan 用户的表

create user yashan identified by welcome1;
grant dba to yashan;
 
create table yashan.dba_objects as select * from sys.dba_objects;
create table yashan.dba_tables as select * from sys.dba_tables;
create table yashan.dba_indexes as select * from sys.dba_indexes;
create table yashan.dba_ind_columns as SELECT INDEX_OWNER, INDEX_NAME, TABLE_OWNER, TABLE_NAME, COLUMN_NAME, COLUMN_POSITION, COLUMN_LENGTH, DESCEND FROM SYS.DBA_IND_COLUMNS;
create table yashan.dba_constraints as SELECT OWNER, CONSTRAINT_NAME, CONSTRAINT_TYPE, TABLE_NAME, INDEX_NAME, INDEX_OWNER, R_OWNER, R_CONSTRAINT_NAME, DELETE_RULE, STATUS, DEFERRABLE, DEFERRED, VALIDATED, GENERATED FROM SYS.DBA_CONSTRAINTS;
create table yashan.dba_cons_columns as SELECT OWNER, CONSTRAINT_NAME, TABLE_NAME, COLUMN_NAME, POSITION FROM SYS.DBA_CONS_COLUMNS;
 
create table yashan.dba_types as select * from sys.dba_types;
create table yashan.dba_views as SELECT OWNER, VIEW_NAME, TEXT_LENGTH, TEXT FROM SYS.DBA_VIEWS;
create table yashan.dba_sequences as select * from sys.dba_sequences;
create table yashan.dba_source as select * from sys.dba_source;
create table yashan.dba_triggers as SELECT OWNER, TRIGGER_NAME, TRIGGER_TYPE, TRIGGERING_EVENT, TABLE_OWNER, BASE_OBJECT_TYPE, TABLE_NAME, COLUMN_NAME, REFERENCING_NAMES, WHEN_CLAUSE, STATUS, DESCRIPTION, ACTION_TYPE FROM SYS.DBA_TRIGGERS;

4、利用数据库能力，直接对比 Oracle 用户和 YashanDB 用户的差异。以下只是参考 SQL，请根据需要更改以下 SQL：

1）查询视图差异

SELECT
        object_type,
        owner,
        object_name,
        o_status,
        y_status
FROM
        (
        SELECT
                nvl(o.object_type, y.object_type) object_type,
                nvl(o.owner, y.owner) owner,
                nvl(o.object_name, y.object_name) object_name,
                o.status o_status,
                y.status y_status
        FROM
                (
                SELECT
                        object_type,
                        owner,
                        object_name,
                        status
                FROM
                        oracle.DBA_OBJECTS
                WHERE
                        OWNER IN ('HR', 'OE', 'SH', 'BI', 'PM', 'IX')
                        AND OBJECT_TYPE = 'VIEW') o
        FULL OUTER JOIN
        (
                SELECT
                        object_type,
                        owner,
                        object_name,
                        status
                FROM
                        yashan.DBA_OBJECTS
                WHERE
                        OWNER IN ('HR', 'OE', 'SH', 'BI', 'PM', 'IX')
                                AND OBJECT_TYPE = 'VIEW') y
ON
                o.object_type = y.object_type
                AND o.owner = y.owner
                AND o.object_name = y.object_name
        ORDER BY
                o.object_type,
                o.owner,
                o.object_name
)
WHERE
        nvl(o_status, 'NOT_EXISTS_IN_ORACLE') != nvl(y_status, 'NOT_EXISTS_IN_YASHAN')
;

2）查询 PROCEDURE 差异

SELECT
        object_type,
        owner,
        object_name,
        o_status,
        y_status
FROM
        (
        SELECT
                nvl(o.object_type, y.object_type) object_type,
                nvl(o.owner, y.owner) owner,
                nvl(o.object_name, y.object_name) object_name,
                o.status o_status,
                y.status y_status
        FROM
                (
                SELECT
                        object_type,
                        owner,
                        object_name,
                        status
                FROM
                        oracle.DBA_OBJECTS
                WHERE
                        OWNER IN ('HR', 'OE', 'SH', 'BI', 'PM', 'IX')
                        AND OBJECT_TYPE = 'PROCEDURE') o
        FULL OUTER JOIN
        (
                SELECT
                        object_type,
                        owner,
                        object_name,
                        status
                FROM
                        yashan.DBA_OBJECTS
                WHERE
                        OWNER IN ('HR', 'OE', 'SH', 'BI', 'PM', 'IX')
                                AND OBJECT_TYPE = 'PROCUDURE') y
ON
                o.object_type = y.object_type
                AND o.owner = y.owner
                AND o.object_name = y.object_name
        ORDER BY
                o.object_type,
                o.owner,
                o.object_name
)
WHERE
        nvl(o_status, 'NOT_EXISTS_IN_ORACLE') != nvl(y_status, 'NOT_EXISTS_IN_YASHAN')

3）查询 INDEX 差异

SELECT
        TABLE_OWNER,
        TABLE_NAME,
        o_index_colum_list,
        y_index_colum_list

                o.index_colum_list o_index_colum_list,
                y.index_colum_list y_index_colum_list
        FROM
                (
                SELECT
                        TABLE_OWNER,
                        TABLE_NAME,
                        LISTAGG(COLUMN_NAME, ',') WITHIN GROUP(
                ORDER BY
                        COLUMN_POSITION) index_colum_list
                FROM
                        oracle.DBA_IND_COLUMNS
                WHERE
                        TABLE_OWNER IN ('HR', 'OE', 'SH', 'BI', 'PM', 'IX')
                GROUP BY
                        TABLE_OWNER,
                        TABLE_NAME) o
        FULL OUTER JOIN
(
                SELECT
                        TABLE_OWNER,
                        TABLE_NAME,
                        LISTAGG(COLUMN_NAME, ',') WITHIN GROUP(
                ORDER BY
                        COLUMN_POSITION) index_colum_list
                FROM
                        yashan.DBA_IND_COLUMNS
                WHERE
                        TABLE_OWNER IN ('HR', 'OE', 'SH', 'BI', 'PM', 'IX')
                GROUP BY
                        TABLE_OWNER,
                        TABLE_NAME) y
ON
                o.TABLE_OWNER = y.TABLE_OWNER
                AND o.TABLE_NAME = y.TABLE_NAME

4）查询约束差异
