Hi there,
I have two columns in my table_a. Both are date_col.
In some cases in Col_date_1 my values are given like this: 11(YYYY)- Dec
In Col_date_2 my values are given like this: Dec- 12(YYYY)
But I need all the dates from Col_date_1 to have the same format:
from 11(YYYY)- Dec to Dec -11(YYYY)
Any tips?
Thanks |

| Use datetime fields for dates, then you won't have these type of issues and searches will be a lot faster. |

Select
cast (c_S as varchar (1) ) as c_S
,(cast(tt_Date as datetime) as tt_date
,O_c
,(cast(I_Date as datetime) as I_Date
,(cast(year(I_Date) as varchar(4))+ '-' + cast(month(I_Date) as varchar(2))) as G
,(cast(year(S_Date) as varchar(4))+ '-' + cast(month(S_Date) as varchar(2))) as S_M
,cast(DATEDIFF(month,I_Date,tt_Date) as varchar (4)) as PP
INTO FINAL_TABLE
FROM date
I have error:
msg 156,level 16, state 1, line 4
If instead of using datetime i use date:
Select
cast (c_S as varchar (1) ) as c_S
,(cast(tt_Date as date) as tt_date
,O_c
,(cast(I_Date as date) as I_Date
,(cast(year(I_Date) as varchar(4))+ '-' + cast(month(I_Date) as varchar(2))) as G
,(cast(year(S_Date) as varchar(4))+ '-' + cast(month(S_Date) as varchar(2))) as S_M
,cast(DATEDIFF(month,I_Date,tt_Date) as varchar (4)) as PP
INTO FINAL_TABLE
FROM date
I have the extraction without errors but still some rows from Col_tt_date are not converted properly and still in reverse.
I dont know what to do,
Thank you

I have extracted the wrong dates into a new table.
Now I just need to update the table and convert the date.
Any tip for the query.
No clue.
Thank you
