Urgent --Multiple updates with one Query on the same column - either SP or Query

Posted on 2004-09-21
Last Modified: 2006-11-17
i have a column that is auto populated daily of type varchar.  I would like a stored procedure that I could execute nightly that would go through the table and update it accordingly.

The table consists of values like "1 year", "2 years", ect.  I want to strip the year(s) off of the table as well as look for some other things.

Is this possible to do in a simple query or stored procedure?

you can use something like this

UPDATE TableNAme SET TableName.Duration = Replace(Replace([Duration],"years",""),"year","")

What sort of other things do you want to look for?

the table contains auto, none, and other values considered invalid so I want to set those to 0.  So the query above will just leave me with the number?

Hmm - something like this, I think:

UPDATE MyTable SET MyField=Str$(Val([MyField]))

should do it. This will update the field to the number if it starts with a number - otherwise, it updates it to 0.

oops, I forgot one thing.  the column also contains either Auto or other.  I have to treat these differently and I have to leave those alone.  I deal with them in the asp code.  so i could do a where myfield <> "other" or myfield <>"auto".  right?

Something like this in that case:

UPDATE MyTable SET MyField=IIf([MyField]='Auto' Or [MyField]='Other',[MyField],Str$(Val([MyField])))

I *think* that will work from asp.
