Question:
Write an SQL statement:
Retrieve the 31st to 40th records in Table A (sqlserver, using the Automatically increasing ID as the primary key, note: the ID may not be consecutive .)
Answer (tested ):
1. Assume that the ID is continuous:
Select top10 *FromAWhereIDNot in(Select Top30 IDFromA)
Or
Select*FromAWhereIDBetween31And40
2. Assume that the ID is discontinuous:
Select top40 *FromAExcept Select Top30 *FromA
Or

index according to your layout selection. in dwt, where should the content in the LBI file be written?
This sentence plays a role. For example, if the "sales ranking" above is the right area of the selection, then after you confirm, the program will index. the content in the LBI (top10.lbi) corresponding to the "sales ranking" is fully read and written to the index. in dwt. At this time, you may have a question: if there is a lot of conten

Based on the author's years of Security Analysis on millions of lines of code, this article draws a conclusion about the vulnerability in application-layer logs. This article discusses the security aspects of applications, logs are often ignored, and proves that applications can obtain many benefits through real-time security checks. This article proposes an operational implementation approach and provides related risk and cost analysis.
