In this lesson, we will learn how to use the built-in SQL System functions to complete the query job. SQL System functions are commonly used, including string functions, date functions, Aggregate functions, and data type conversion, auto-increment functions, and null functions in other function frameworks. The several functions mentioned later have been used in the previous sections. Today we will learn the first two functions. String functions: 1. charindex (): Returns the starting positi

In the teaching management, in order to facilitate management and information collection will produce a variety of forms, such as "Student Information table", "Semester performance form", "volunteer to report" and so on. The author makes use of the powerful table function with WPS text to take the production of "Student Information table" as an example to demonstrate the process of making information table.

Teachers often use Excel to make forms, input student information, Excel powerful tabulation function, bring convenience to the teacher work, but in the form of data entry process will inevitably error, inadvertently will input some wrong data, such as duplicate ID number, out of range of invalid data. In fact, as long as a reasonable set of "data Validation" rules, you can avoid errors. Instance one: My id you don't use it. To facilitate the manage
