I want to calculate the experience of the employees

which was in the excel sheet i export the data to the

sqlserver using the query

select * into ManPowerCommon FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=D:\Book.xls;HDR=YES',
'SELECT * FROM [Common$]')

in the excel sheet d date in d format 5th january 2005

first I replace d string th or nd or rd or st by space

then i apply d query


select datediff(year,replace(F9,substring(F9,patindex('%nd%',F9)+ patindex('%rd%',F9)+ patindex('%th%',F9)+ patindex('%st%',F9),2),' '),convert(varchar(20),getdate()))
as "ExpInHC(in Years)", datediff(month,replace(F9,substring(F9,patindex('%nd%',F9)+ patindex('%rd%',F9)+ patindex('%th%',F9)+ patindex('%st%',F9),2),' '),convert(varchar(20),getdate()))"ExpInHC(in Month)"
from ManPowerCommon where F9 != 'Date of Joining HC'and F9 != 'Null' and patindex('%ust_%',f9)<=3

it will work for otherdates except the date having d month name

"August" because it will search d path index for d day and also

st which is in august add the both indexpositions but it is not

displayed. can u suggest me how to take only one index except

"st" in august.

Waiting for suggestion ....

Thanks

Rajashekar."

Either replace "st " with space, instead of replacing just "st", or assume that "august" has become "augu" and treat that as a "valid" month, or re-replace "augu" with "august" AFTER the "st" replace with space so that it becomes "august" again.
