SQL Fiddle

Oracle 11g R2架构设置：

CREATE TABLE SCORES (Score ) AS
          SELECT '1-2' FROM DUAL
UNION ALL SELECT '10-1' FROM DUAL
UNION ALL SELECT '999-999' FROM DUAL
UNION ALL SELECT '99-99' FROM DUAL
UNION ALL SELECT '1000-1000' FROM DUAL;

查询1 ：

SELECT SCORE,
       CASE WHEN REGEXP_LIKE( SCORE, '^\d{1,3}-\d{1,3}$' )
            THEN 'Valid'
            ELSE 'Invalid'
            END AS Validity
FROM   SCORES

<强> Results ：

|     SCORE | VALIDITY |
|-----------|----------|
|       1-2 |    Valid |
|      10-1 |    Valid |
|   999-999 |    Valid |
|     99-99 |    Valid |
| 1000-1000 |  Invalid |

将格式编号的列检查添加到编号oracle
