我要mssql版本的别给我Mysql和Oracle的
mysql> select * from t_fengchujun;
+------+--------------------+------+
| a
| b
| c
|
+------+--------------------+------+
|
1 | fsdf-fefw-few-fegh | d
|
|
2 | fhtre-reh-eh-jeg |fd|
|
3 | hjre-heg-wfbc
|d |
+------+--------------------+------+
3 rows in set (0.00 sec)
mysql> select a,
->SUBSTRING_INDEX(concat(b,'----'),'-',1) as b1,
->SUBSTRING_INDEX(SUBSTRING_INDEX(concat(b,'----'),'-',2),'-',-1) as b2,
->SUBSTRING_INDEX(SUBSTRING_INDEX(concat(b,'----'),'-',3),'-',-1) as b3,
->SUBSTRING_INDEX(SUBSTRING_INDEX(concat(b,'----'),'-',4),'-',-1) as b4,
->c
-> from t_fengchujun;
+------+-------+------+------+------+------+
| a
| b1
| b2 | b3 | b4 | c
|
|
1 | fsdf| fefw | few| fegh | d
|
|
2 | fhtre | reh| eh | jeg|fd|
|
3 | hjre| heg| wfbc |
|d |
就是这种效果如何达到，上边是mysql的希望能转换成mssql的
