Querying SQL Server 2012: Part II - CodeProject
8.1 CROSS APPLY The CROSS APPLY operator works like an INNER JOIN in that it can match rows from two tables and leaves out rows that were not matched by the other table in the result. The following query gets the top three most expensive orders regardless of customer and as a result each Person is duplicated three times in the result (once for each order, regardless of whether the order was placed by this Person)
There are a number of reasons for poor storage performance, but measuring it and understanding what needs to be measured and monitored is always a useful exercise

Either because you already have the data in a table, as in the case of table-valued parameters, or you skip the table entirely as you do with dynamic SQL or when you use many parameters. As I discussed above in the section Inline, Multi-Statement and Temp Tables, inline T-SQL functions gives the optimizer a degree of freedom which is not really good for its health
Second, the minimum and maximum memory amounts are important, especially since we gave the SQL Server account the permission to lock its pages in memory. John writes: I also like to go to model and change the recovery model from FULL since we use SIMPLE a lot, even in production and also change the datafile autogrowth setting from 1 MB
Paging in SQL Server 2005
The record count is used to prevent returning empty results when possible, and to support paging interfaces that calculate the number of pages available (such as GridView). If we were calling this stored procedure to populate a GridView, we would return @recct as a ReturnValue parameter instead of using a result set, but we will use a result set for demonstration purposes
MySQL :: MySQL 5.0 Reference Manual :: 12.16.1 GROUP BY (Aggregate) Functions
(Before MySQL 5.0.3, SUM() and AVG() return DOUBLE for all numeric arguments.) The SUM() and AVG() aggregate functions do not work with temporal values. But if it's not indexed, SQL would have to evaluate each row individually anyway.You can take the idea a stage further by using a WHERE clause on the query too
This formula just returns the "month offset from the base date", or the number number of months between the "base date" of 0 and the transaction's date, as an integer. i need the last amount entry ...if i have a amount entry on the last day of the month or before or on 10 of the next month i have to show that value in last month
Querying SQL Server 2012: Part I - CodeProject
That would at least qualify for a LEFT OUTER JOIN, but there are also CurrencyRates that do not have orders, which would also qualify a join between the tables for a RIGHT OUTER JOIN. Since order is not guaranteed in SQL Server it would be logical to use an ORDER BY, but maybe you really do want to skip a few random rows after which you select a few other random rows

From a relational standpoint, it is perfectly valid to GROUP BY fields that you know are attributes of an entity whose identifier is also included in the GROUP BY. One more common mistake is that people just mimic the expressions in their SELECT list in the GROUP BY clause, without thinking logically about what grouping is really necessary
How to use GROUP BY to concatenate strings in SQL Server? - Stack Overflow
I would have added it as a comment, but I don't have enough points yet :) I was using this idea for a view I was working on, however the items I was concatinating contained spaces
In other words, the query you used will return any record where the returned column values, taken together, are different from any other record in the result set.
