下面比如我们要显示student表中所有的数据信息,我们就可以利用sqlite3_get_table()执行语句: select * from student 实现代码如下: void do_show_sample(sqlite3 *db) { char **result, *errmsg; int nrow, ncolumn, i, j, index; if (sqlite3_get_table(db, "select * from student", &result, &nro...
和sqlite3_exec()这种使用回调函数的方式不同,sqlite3_get_table()的功能要显得更加直接。它通过控制语句的传入,直接将参数赋值给指针传出。来看一下函数原型: #include<sqlite3.h>intsqlite3_get_table(sqlite3* db,char* order,char* **dResult,int*nRow,int*nColnm,char**errmsg);//参数释义/* ...

排序是在你的SQL语句中进行的，如SELECT ... ORDER BY ctime,sqlite3_get_table只是获取你sql语句的执行结果，得到一个一维数组，先记录字段名 接下来为字段的值 可以
sqlite3_get_table 使用举例 void GetTable() { sqlite3 * db; int result; char * errmsg = NULL; char **dbResult; //是 char ** 类型,两个*号 int nRow, nColumn; int i , j; int index; result = sqlite3_open( “c:\\Dcg_database.db ”, db ); if( result != SQLITE_OK ) { ...
