在linux下通过C语言基于freetds连接sql2000

在linux下通过C语言基于freetds连接sql2000

安装好freetds之后
添加库的环境变量
$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/freetds/lib/
之后开vi
#include <stdio.h>
#include <string.h>
#include <stdio.h>
#include <unistd.h>
#include </usr/local/freetds/include/sybfront.h>
#include </usr/local/freetds/include/sybdb.h>

{

}

dbinit();

if(dbsqlexec(dbprocess) == FAIL){
echo("query fail...");
return 0;
}
DBINT result_code;
char uid[20];
char nickname[100];
char email[200];
int rows = 0;
while((result_code = dbresults(dbprocess))!= NO_MORE_RESULTS)
{
if(result_code == SUCCEED)
{

}
}

dbclose(dbprocess);

return 0;

}
