———- Pos function Returns the index value of the first character in a specified substring that occurs in a given string. Unit System Category string handling routines function Pos(Substr: string; S: string): Integer; Description Pos searches for a substring, Substr, in a string, S. Subst...
1.使用StringUtils,需要导包 String strs = "abcdef1003535197"; System.out.println("===2===" + StringUtils.substringBefore(strs, "3")); //从开始截取到第一个“3”(不包含) System.out.println("===3===" + StringUtils.substringBefore SQL中字符串截取...

Pos:Locates a substring in a given string.The Pos method returns an index of the first occurence of Substr in Str, starting the search at Offset.This method returns zero if Substr is not found or Offset is invalid (for example, if Offset exceeds the String length or is less ...

This function searches for a substring within another string and returns the substring’s position in that string. If you use Pos to search for a character — [Delphi] i := Pos(‘w’, ‘Hello, world!’); — the compiler generates the binary code that transforms the character to a strin...
