c++拆分字符串方法: #include <iostream>#include <string>#include <sstream>#include <algorithm>#include <iterator> int main() {using namespace std;string sentence = "Something in the way she moves...";istringstream iss(sente
一.C#在不同情况下连接SQLite字符串格式 1.Basic(基本的) Data Source=filename;Version=3; 2.Using UTF16(使用UTF16编码) Data Source=filename;Version=3;UseUTF16Encoding=True; 3.With password(带密码的) Data Source=filename;Version=3;Password=myPassword; 4.Using the pre 3.3x databas
1. // 根据字符串,拆分字符串,相当于vb中的split函数 function SplitString(const Source, ch: string): TStringList; var temp: String; i: Integer; begin Result := TStringList.Create; // 如果是空自符串则返回空列表 if Source = '' then exit; temp := Source; i := pos(ch, Source); while i <
一.拆分字符串为若干行 例一:要求将表emp中的'king'按照每行一个单词拆成四行 注意:substr(str,pos):截取pos位置开始的字符: substr(str,pos,len):从pos位置开始,选出接下去的len个字符 表emp: eid ename 1 ring 2 king 3 ting 4 ping 首先,建立表tmp(基干表,为了配合表一使用): tid 1 2 3 4 5 然后,select emp.ename,tmp.tid from emp,tmp where em
