这个是ODBC API操作数据库的一组语句.
sprintf(sqls,"%sdasi_insert %d,'%s %d:%d',%d,%d",hisdb,vid,buf,hour,minu,ival,flags);
这个是格式化sqls的操作,将后面的参数hisdb,vid,buf,hour,minu,ival,flagsf分别格式化%sdasi_insert %d,'%s %d:%d',%d,%d中,buf,hour,minu对应的是'%s %d:%d'里面的.
SQLExecDirect(hstmt,(BYTE*)sqls,SQL_NTS); //这个是执行sql语句
SQLFreeStmt(hstmt,SQL_CLOSE); //这个是释放sql句柄.
ODBC API你可以晚上搜一下,有很多示例的.微软官网msdn上面也有API的具体用法.这样的资料很多的,你一看就知道了.
