The actual example code below can put the results of a query into a custom table, and you can then query the data from this custom table:
With AA as
(SELECT ticketnumber, TicketType, versionnumber, Stagename, dtanalyzed,
Gisprocessid, Processstatus , dtreceived, USERID, USERNAME, FIRSTNAME,
LASTNAME, numberofdays from
Report_performanceofanalyzer
WHERE (dtanalyzed is NULL)
UNION all
SELECT ticketnumber, TicketType, versionnumber, Stagename, dtana

Dynamic | data | Database Suppose we add more shippers to the table, as shown in Listing 4 (the ShipperID column has the identity attribute and SQL Server automatically generates a value for that column).
"Listing 4: Insert some records into the Shippers table"
INSERT into Shippers VALUES (' Shipper4 ', ' (111) 222-9999 ')
INSERT into Shippers VALUES (' Shipper5 ', ' (111) 222-8888 ')

Imagine a scenario under high concurrency: Suppose we store name=aty in the cache and set the expiration time. When the cache expires, there are exactly 10 client-initiated requests that need to read the value of name. Using the guava cache ensures that only one thread is allowed to load data (such as from a database), while other threads wait for the thread to return results. This avoids a large number of user requests to penetrate the cache.

Bitwise and of Numbers Range
Original title link bitwise AND of Numbers Range
Calculating the results of all numbers in the range of [m:n] [m:n] [m:n]
First you need to clarify a few knowledge points a (a+1) A (A + 1) a \ (A + 1) the lowest bit must be 0 0b 0 B 0 \ b The result must be 0 a (a+1) (A + 2) ... (A+k) A (A + 1) (A + 2) ... (A + K) a \ (A + 1) \ (A + 2) \ The lowest bit of \ (A + K) must be 0.
So if n > m, then [M:N] [m:n] [m:n
