Tags: resource statement second Ora online table also requires a script mergeThis is the ultimate problem, because the complexity of optimization itself is difficult to summarize, many times the method of optimization is not the use of the mysterious technology, but only a level of ideological differences, and these are likely to lead to significant performance differences.So sometimes we need to figure out what the demand is and whether SQL itself is

There were no things left idle in the past two days, and the project was soon launched. I read all the SQL statements I wrote in the project. With reference to the experience of optimizing SQL statements in previous years and the summary of SQL statement optimization methods on the Internet, and the powerful SQL analys

and oracle call interface.1. In the oracle development environment, we can use the dbms_lob package for processing! Dbms_lob package is powerful and simple to use. It can be used to read internal lob objects or process bfile objects. However, there is a difference between the two. Read and Write operations can be performed when processing internal lob objects (blob, clob), but read operations can only be p

their definition does not paste and be changed. Contention for a latch increases the execution time of the statement and reduces concurrency. Soft parsing any ill-resolved parsing isSoft parsing。 If you submit a statement that is the same as a reusable SQL statement in a shared type, the database reuses that existing code. Reuse code is also known asLibrary Cache Hit。 General, soft parsing is preferable to hard parsing because the database can
