Question

I had a table like this

id   |   name 
------------------
1    |   SAM1
2    |   SAM2
1    |   SAM1
3    |   SAM3
7    |   SAM7
6    |   SAM6

I need to show the results using this query

SELECT name,id FROM tblnameWHERE id IN (1,2,7,6,1)

and getting the following result

id   |   name 
------------------
1    |   SAM1
2    |   SAM2
7    |   SAM7
6    |   SAM6

My problem is this skipped last id , ie 1 . I need something like this

id   |   name 
------------------
1    |   SAM1
2    |   SAM2
7    |   SAM7
6    |   SAM6
1    |   SAM1

With out using the loop query ( like follows ) any other method for doing this ?

$ids=array(1,2,7,6,1);
$i=0;
foreach($ids as $id){

$sql=mysql_query("SELECT * FROM tblname WHERE id=$id");
// Store value to array 

}

Please help

The query

SELECT name,id FROM tblname WHERE id IN (1,2,7,6);

should show duplicate rows; e.g. if there are really in the table two distinct rows with the very same id, then the query will show them (since there’s no DISTINCT keyword).

Instead, if you want to create duplicate lines starting from a table containing single lines, you have to join your table with a table having repeated 1 (in your case); another way could be to use union like this:

SELECT  name, id FROM tblname WHERE id IN (1,2,7,6)
  UNION ALL
SELECT name, id FROM tblname WHERE id = 1;

Edit

Since your id is a primary key, it will be unique, hence the “problem” you’re experiencing. If you want to allow duplicate rows on insert, remove the primary key. If you need it, consider the possible solutions suggested above.
