In the past two days, the ACCESS database was reluctantly used, and the result was put together by the bool data type.Bool help information in access: "yes" and "no", and fields that only contain one of the two (Yes/No, true/false, or on/off ).In MSSQL, MySQL contains integer data that is expressed as 1 or 0 in bits.The query statement in MSSQL: Select * from use

If you use this statement in MS SQL Server: The code is as follows Copy Code Select Top 2 * from test01 Oracle's statement: The code is as follows Copy Code SELECT * FROM (select RowNum r, * from test) Ttwhere TT.R > and TT.R (preferably with a plsql cursor) In DB2: The code is as follows Copy Code SELECT * FROM payment to fetch first 5 row only--check the top 5 records

SQL Server randomly reads several records from a table: Example: The code is as follows Copy Code Select top Id,title from News order by NEWID () After optimization In MSSQL, the following methods were used to randomly read more than 3W of data, which took only 1-2 seconds. But in the actual use, certainly does not randomly read so many data MSSQL The c

Label:Currently, Haproxy has been used to load balance the MSSQL read library, which runs well in the production environment.However, this scenario has drawbacks: the client needs to choose whether to use a read library or a write library. This is still not convenient, if you can implement automatic routing is better, that is, let Haproxy automatically choose to send the request to read library or write library.I plan to write a haproxy module that im

Label:Today, database operations are increasingly becoming a performance bottleneck for the entire application, which is especially noticeable for web applications. It's not just about the performance of the database that DBAs need to worry about, it's something that our programmers need to focus on. When we design the database table structure, we need to pay attention to the
