Cosider the Following PassthruEsql Query

SELECT VALUE m from Members AS m WHERE (1=1) AND ( (0=1) or (m.SSN like '_Data_') or (m.MemberName.LastName like '_Data_') or (m.BirthDate = 7/23/1958 12:00:00 AM) or (m.Contact.Phone like '_Data_') )

When i run above PassthruEsqlQuery it gives following error :

IdeaBlade.EntityModel.v4.EntityServerException: The query syntax is not valid, near term '12', line 1, column 163. --->  System.Data.QueryException: The query syntax is not valid, near term '12', line 1, column 163.

When i remove m.birthdate part from PassthruEsqlQuery it works fine and gives me the result.

so pl. tell whats wrong with Date Part in above passthruESql Query.

Thanks

Since this is a pass through query, the syntax is validated by the Entity Framework and must meet EF eSQL requirements.  Date literals are a little tricky and need to be formatted something like this:
  Datetime 'yyyy-mm-dd hh:mm'
 
So, your birthdate clause should work if rewritten like this:
    (m.BirthDate = Datetime'1958-07-23 00:00')
 
Here's a link to some info on eSQL literal support:  http://msdn.microsoft.com/en-us/library/bb399176.aspx - http://msdn.microsoft.com/en-us/library/bb399176.aspx
