[sublogix] Operator.IsNull and Operator.IsNotNull ? Your last visit to this thread was on 1/1/1970 12:00:00 AM

How to query some table using sublogix to make 'is not null' or 'is null' conditions?

I need something like this:

IList contracts = repository.Select()
.Where("AccountId", Operator.Equals, SlxAccountId)
.And(Operator.IsNotNull("EndingDate"))
.Execute();

or this:

IList contracts = repository.Select()
.Where("AccountId", Operator.Equals, SlxAccountId)
.And("EndingDate", Operator.IsNotNull)
.Execute();

Unfortunately, there are no workaround - i've tried so:

IList contracts = repository.Select()
.Where("AccountId", Operator.Equals, SlxAccountId)
//.And("EndingDate", Operator.IsNot, DBNull.Value )
//.And("EndingDate", Operator.IsNot, null )
//.And("EndingDate", Operator.Equals, DBNull.Value )
//.And("EndingDate", Operator.Equals, null )
.Execute();

Of course, I can use client-side LINQ expressions, but it's not good desision:

IList contracts = repository.Select()
.Where("AccountId", Operator.Equals, SlxAccountId)
.Execute()
.Where(x => x.Endingdate == null && x.Startdate != null ).ToList();

Andrei,

I have posted a new version of Sublogix (version 1.3.0.0) which fixes this bug. To query for null values you can do the following:

var repo = new Repository(ConnectionString);
var list = repo.Select()
	       .Where("Assistant", Operator.Is, DBNull.Value)
	       .Execute();

To get this new version use the NuGet package manager to get the updated assembly.

Ryan
