Storing the result of a FETCH in an array (Pro*C)

Hi,
I'm trying, inside a for loop, in Pro*C,
TO STORE the result of a fetch in an array,
but I don't want any repeated result in my result array (tableau_stockage in the example)
the following CODE doesnt WORK, a lot of identical data IS repeated.

How do i do that ? thanks IN advance

Code:

int i, j;
char v_period_name[1000]; 		
CHAR tableau_stockage[MAX_TAB_PERIOD][20]; 

/* initialisation */
        	for(i = 0; i < 1000; i++)
       		 {
			v_period_name[i] = '\0';
        	}      
 

EXEC SQL BEGIN DECLARE SECTION;	
varchar 	v_period_name_l[1000][25];
EXEC SQL END DECLARE SECTION;	

EXEC SQL DECLARE cursor_1 CURSOR FOR
                   SELECT 
                           myvalue
                      FROM mytable;
                      
EXEC SQL OPEN  cursor_1;              

while (1) 
        {   EXEC SQL                                                              
            FETCH cursor_1                                               
            INTO  :v_period_name_l;

for ( i = 0; i < Nb_Enr_Traites_Bloc; i++ )                                           
          {                       	          	    	
        
	      strncpy(v_period_name, (char *) v_period_name_l[i].arr, 16);
	      v_period_name[16] = '\0';	          	          
	       	       		       	       	      
 	      for (j = 0; j < MAX_TAB_PERIOD; j++)  
	            {	            	
	               if (!(strcmp(tableau_stockage[j], v_period_name) == 0))                                    
	                {	
	                	
	                if (tableau_stockage[j] == '\0'){
			  strcpy(tableau_stockage[j], v_period_name); 						
              		  tableau_stockage[j][16] = '\0';              		  		              	                      		  
                       }
              		  break; 
                    	}              	                            	            
                    }     	    	
          }  /* end for */

 }/* End while */            

        EXEC SQL CLOSE cursor_1;

Try some logic like this:

Code:

Read new record into temp variable
FoundIt = false
For I = 0 to MAX_TAB_PERIOD
  if TableRow[I] equals newitem
  {
    FoundIt = true;
    break;
  }
End For

if (FoundIt == true)
{
    Add newitem to the table
}

The other thing that you can do is use the keyword DISTINCT in your SQL SELECT statement.

thanks for your help
