If you don t want to return self matches, add the expression S1.id <> S2.id to the join condition . Just remember that if you make this change, sessions that don t overlap with any other session will not show up which may very well be desired behavior . If you do want such sessions to show up, make sure that you change the join type to an outer join . You can perform logical transformation, converting the OR logic in the join condition to AND logic, and produce a shorter expression: winforms barcode reader Neodynamic.SDK.BarcodeReader.Sample ... - NuGet Gallery

KeepDynamic.com/barcode. android barcode scanner source code java. using resolution swing to insert barcodes in asp.net web,windows application. To permanently add our new task to your Ant installation, you can edit the defaults.properties file in the Ant distribution JAR, adding its name and class name to Ant permanently. Taking the permanent approach means you need not explicitly declare the taskdef element in your build files anymore. See the comments in build.xml for more details. If you think about it, for two sessions to overlap, one must end on or after the other starts, and start on or before the other ends . AND logic transformed from OR logic is usually more confusing and tricky than the source . It requires some getting used to . But converting to AND logic might be worthwhile because the optimizer can handle AND logic more efficiently . Here s the full solution query: SELECT S1.username, S1.id AS key1, S1.starttime AS start1, S1.endtime AS end1, S2.id AS key2, S2.starttime AS start2, S2.endtime AS end2 FROM dbo.Sessions AS S1 JOIN dbo.Sessions AS S2 ON S2.username = S1.username AND (S2.endtime >= S1.starttime AND S2.starttime <= S1.endtime); The next problem we ll look at requires you to combine, or merge, all overlapping sessions for the same user into one session group, returning the user, start time, and end time of the session group . The purpose of such a request is to determine the amount of time a user was connected, regardless of the number of simultaneous active sessions the user had . The solution to this problem would be especially helpful to service providers that allow multiple sessions at no extra charge . You might want to tackle the problem in steps: identify starting times of session groups, identify ending times of session groups, and then match each ending time to its corresponding starting time . winforms barcode scanner WinForm Barcode Reader with Webcam and C# - Code Pool
