/* send SQL query */
 if (mysql_query(conn, "SELECT * FROM branch")) {

here is the code in question:




char input[80];
printf ("Enter a branch name: ");
scanf ("%s",input);

char phrase[125];

strcpy(phrase,"SELECT Title FROM Book Branch WHERE BranchName=");
strcat(phrase,input);


/* send SQL query */
if (mysql_query(conn,phrase))
//mysql_query
{
fprintf(stderr, "%s\n", mysql_error(conn));
exit(1);
}

//etc.....
