我连接到一个Access 2010数据库。问题是我的查询没有返回一个数字。任何帮助表示赞赏。谢谢。
/* Connect to the 'Fileber.accdb' database */
rc = SQLDriverConnect(hDbc, NULL, szDSN, _countof(szDSN),
szConnStrOut, 255, &iConnStrLength2Ptr, SQL_DRIVER_NOPROMPT);
if (SQL_SUCCEEDED(rc))
{
printf("%s: Successfully connected to database. Data source name: \n %s\n", DAM, szConnStrOut);
const char* TOTL;
TOTL = "SELECT COUNT(*) FROM tblClients";
printf("%s: Total of Clients %s.\n", TOTL);
}
else
{
printf("%s: Couldn't connect to %s.\n", DAM, szDSN);
}
