Inserting hexadecimal in 1 row into MYSQL

Hi all, I'm currently doing my final year project and im stuck on the following section.

Whenever i read from the RFID reader, its a 96 bit hexa value. However when i try to insert that value into MYSQL it appears to be in 12 different rows instead of in 1 row. For example, if the hexa value was 0A 60 00 00 00 00 00 00 00 00 00 01, Whenever use the insert function below, it appears as 12 different entries.(0A) would be in the first row, (60) would be in the second row and so on.

Can someone please help me solve the problem. Thanks.

the codes are as follow:

void CT1121Dlg::DisplayTagData(int cnt,int tag_len,int start_index)

MYSQL *pConnection;
char Query[256];
int a;
int z = 25;
int fields;
pConnection = mysql_init(NULL);

CString s,s0;
int i,j;
unsigned char t;
for(i = 0; i < cnt; i++)
s.Format("NO.%d: ",start_index+i+1);

for(j = 0; j < tag_len; j++)
t = IdBuf.Ids[j];
if(t < 0x10)
s0.Format("0%X ",t);

sprintf(Query, "insert into t(d) values ((%X))",t);
if ( mysql_query(pConnection,Query) == 0 )
{pResult = mysql_store_result( pConnection );
if ( pResult != NULL )
fields = mysql_num_rows( pResult );
printf( "Retrieved %u rows\n", fields );}
printf( "Query failed\n" );
s0.Format("%X ",t);

s += s0;
