1. sqlite does not have the built-in function of ToUpper. It doesn't matter. We can create it; 2. sqlite cannot directly create user-defined functions. It cannot be easily created and used as in SQL server. It doesn't matter. We can still create it.

As data volumes grow at an alarming rate, the database management system continues to focus on performance issues. This paper mainly introduces a performance tuning technique named function index (functional index). Creating and using functional

  A few days ago, N Articles reported that C #/. NET was too slow and required to delete some features of C #/. NET. C #/. NET Slow seems to be recognized by the industry, no matter how you prove C #/. NET is actually not much slower than C ++, but

It is often used to convert strings and numbers. It is easy to collect and sort them. Then you can use atof (convert string to float type) atoi (convert string to integer type) atol (convert string to integer type) strtol (convert string to floating

In the previous article (pointing to a function pointer example), we mentioned that there are two logically inconsistent syntax rules for using a function pointer to implement such an operation, and we will discuss it in the form of a question, in
