Why are my SQL Server results always wrong?
This may mean forcing your users to select from a calendar control or set of drop-downs, because if you’re letting them type, you can never be absolutely certain whether they meant August 9th or September 8th. One query strategy that I have always found problematic is the use of BETWEEN for date range queries.
Is it possible to return the wrong result in Excel?
The following can never return the wrong results (e.g. will always return all of the data for February, and only the data for February), regardless of what you do to the data types of the parameters or underlying columns: DECLARE @start datetime = ‘20160201’, @end datetime = DATEADD(MONTH, 1, ‘20160201’); SELECT
When do you miss data in SQL Server?
If the parameter is smalldatetime, then BETWEEN @start AND @sdt will include any data from March 1st with a time of midnight. If the parameter is datetime2, the end range is rounded down, so in theory, you could miss data from 23:59:59.997 (or .9999999 if the underlying data type is datetime2 ).
When does a scrollable cursor return to the calling batch?
For a scrollable cursor, all the rows in the result set are returned to the calling batch, procedure, or trigger when the procedure exits. When returned, the cursor position is left at the position of the last fetch executed in the procedure.
Why are the events returned from the wrong date?
The user might not even notice that the events returned are from the wrong date, since often internationalization is missed at the presentation layer too – so it will display 9/8/2016, just like the user typed.
What causes a query to behave like an inner join?
A situation I see a lot out on forums is when a user is performing an outer join but the query behaves like an inner join. This is often because some of the criteria meant for the outer table is expressed in the WHERE clause instead of the JOIN clause.
What happens if you make a Power Query error?
The good news is that you can always discard changes and start again. Data type errors will not prevent the data loading into the query; instead, those cells will be loaded as blank. Queries and Connections pane shows the error and indicates the number of lines with errors.
When to use in, not, and like in SQL?
Some SQL keywords that help you build complex statements include IN, NOT, and LIKE. LIKE uses wildcards, which are used to query similar values, but IN and NOT return precise record sets based on specific values.
