This article will explain in detail what are the problems in optimizing your database performance, and the content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

You may not take advantage of these details when optimizing your database. You need to ask yourself about the performance of your database. The following editor will explain what are the problems in optimizing your database performance?

What are the problems with optimizing your database performance

1. Assuming that your database does not need the ability to store special characters, especially those specified in the Unicode standard, have you replaced the nchar type with various applicable field types such as char in the system?

two。 Are you using the smalldatetime type instead of datetime? If you don't know the difference between the two types, this is a brief introduction: the smalldatetime type can store dates from January 1, 1900 to June 6, 2079, while the datetime type extends this range from January 1, 1753 to December 31, 9999. Do you need such a large area?

3. Do you routinely use bit types instead of smallint types? If so, do you know the price? This may not affect your program, but the smallint type can be indexed, not the bit type.

4. SQL Server 2000 allows null values in bit type fields and is the default. Some people want this, while others do not.

5. How do you deal with null values in fields? The default is to allow null values, but a better way is to disable null values and allow zero-length strings.

What are the problems with optimizing your database performance

6. Have you ever thought about the maximum number of rows that can be contained in the table? Have you compared this number with the data page size of 8060 bytes?

7. Did you make good use of the standard fields? (check out the tools on the menu-> options-> Standard fields)

8. Is there a timestamp field in your table? If not, do you know when this field will be useful?

9. Do all your watches have a block index? Do you know when a table should have a block index and when it is worthless?

10. Do you use the sp_ prefix when naming stored procedures? Do you realize what impact this has on performance?

A good way to avoid these common development problems is to use SSW's SQL Auditor, which can review far more than the 10 things I've listed. The price of SQL Auditor is reasonable. The best thing is that you can download the beta version and try it 20 times before you pay for it. SSW's trial strategy attracted me, probably because I often downloaded some trial software with a 14-day limit and then forgot to run it until the trial period was over.

On the optimization of your database performance what questions to share here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
