Label:Introduction to OLE DB Wait eventsThe OLE DB wait type is one of the most common wait types in a SQL SERVER database. It means that a session (SPID) has a call request through SQL Server Native Client OLE DB provider and waits for the database to return the required data. It appears in the remote system or the ne

View SQL statements with high CPU usage Create indexes to reduce table scans Other Optimization Methods Summary Problems encountered Some colleagues reported that the server's CPU usage was too high. At first glance, it was basically 100%, my god. This is a big problem. Let's take a look. Let colleagues check the system process and find that the CPU usage of SQLServer is high. The first thought was whether the report was generated at a hi

stored procedure can be nested, that is, one stored procedure can invoke another stored procedure. When the invoked procedure starts executing, the nesting level is incremented, and the nesting level is reduced after the called procedure has finished executing. If the maximum nesting level is exceeded, the entire call process chain fails. You can use the @ @NESTLEVEL function to return the current nesting level. To estimate the size of the compiled stored procedure, use the following performan

query logical reads 20 times, pre-read 2 times, no physical read ..., and the table with the clustered index logic read 23 times, read 22 times! There are also statistical inaccuracies that result in physical reads 1 times! .... So it's a lot better than a stack table scan.Of course, in order to further analysis, in fact, the reason for the difference is simple: The table with the clustered index because of its stored structure (b-tree), so the logical IO is definitely 3 more, because from the

Snapshot replication: By setting a fixed time period for replication, the time cycle range can be set arbitrarily between one minute to one months, is the most stable of three replication functions. Things to replicate: through real-time monitoring of database updates, each update to the data and database objects to replicate, real-time performance is best, but the SQL

Transaction logs are very important but often ignored in the database structure. Since it is not as active as the schema in the database, few people are concerned about transaction logs. Transaction logs are records of database changes. They can record any operations on the database and save the record results in an independent file. Transaction logs are fully recorded for every transaction process. Based on these records, data files can be restored to the pre-transaction status. Starting from t
