SELECT sysxml.XPathValue(O.CAST(xmlOrder VARCHAR(1000) CHARACTER SET UNICODE), '//ORDER/PO_NUMBER/*') AS PO_Number,
sysxml.XPathValue(O.CAST(xmlOrder VARCHAR(1000) CHARACTER SET UNICODE), '//ORDER/DATE/*') AS theDate
FROM COMMON.OrderLog O
WHERE sysxml.XPathValue(O.CAST(xmlOrder VARCHAR(1000) CHARACTER SET UNICODE), '//ORDER/BILLTO/*') = 'Mike';
The CAST is not part of O, and xmlOrder probably is.
So instead of this:
O.CAST(xmlOrder ...
you probably need to do this in all three lines:
CAST(O.xmlOrder ...

I have a table in my app
CREATE TABLE VisitDetails (VisitId INTEGER, UserId TEXT, VisitNumber
TEXT, JobId INTEGER, JobNumber TEXT, StatusId INTEGER, Status TEXT,
SignatureRequired BOOL, StatusDate TIMESTAMP DEFAULT CURRENT_TIMESTAMP
,StartDate TIMESTAMP DEFAULT CURRENT_TIMESTAMP, EndDate TIMESTAMP
DEFAULT CURRENT_TIMESTAMP, IsPPMJob BOOL)
and it was working fine but now I need to alter this table to make already existing column 'VisitId' to become the primary key. Can somebody help me please? It might work by adding Unique constraint to VisitId column of the table but I am trying to put some efficient solution !
You can't change SQLite tables field's primary key once the table is created,
Possible solution is,
Create new table with desired primary key
Copy all data
Drop old table

I want to update details using linq to entities. But instead of takin a new aspx page i want to update details in another view. will it work.? and please give the linq to entity update query
Let us assume:
db is the context of your Database Entity.
Table_name is the name of Table you need to update.
row_id is the value you are using to search for the data in the Table.
To update using linq you need to fetch the record first using the below query:
var data = (from r in db.Table_name
where r.id == row_id
select r).FirstOrDefault();
Now to update the values just update them. For example:
data.Name = "Firstname lastname"
data.IsActive = true;
.
.
and so on
After you have updated the values in data you need to Save the changes made by you by this command:
db.SaveChanges();
That's it.
