Help in retreiving database data using a loop

Question

Hi, new here, please help me with my problem.
In my database table, (SQL) I have 2 coloumns AgtName and Tier1.
Within this table there are these data
AgtName Tier1
a b
b c
c d
d NA
e b
My orginal plan was to use JSTL to retreive the data in a loop function. It will search the second coloumn and retreive data in a zigzag style. It would also stop when the data is NA
An example is when the search paramater is 'a', it would retreive the data like this ' b c d NA'
If it is 'e', it would be 'b c d NA'
These are my codes
<c:choose>
<c:when test="${param.search!=null}">
<sql:query var="result2" dataSource="${dataSource}">
select * from testinzigzag
where Name like ?
<sql:param value="${param.search}" />
</sql:query>
<c:forEach var="row2" items="${result2.rows}">
<c:choose>
<c:when test="${row2.UpperTier!='NA'}">
${row2.UpperTier}
<c:set var="loopVar" value="${row2.UpperTier}" />
<!-- Start:You will have to start the coding part here -->
<c:choose>
<c:when test="${row2.UpperTier!='NA'}">
<sql:query var="result3" dataSource="${dataSource}">
select * from testinzigzag
where Name like ?
<sql:param value="${row2.UpperTier}" />
</sql:query>
<c:forEach var="row3" items="${result3.rows}">
${row3.UpperTier}
<c:choose>
<c:when test="${row3.UpperTier!='NA'}">
<sql:query var="result4" dataSource="${dataSource}">
select * from testinzigzag
where Name like ?
<sql:param value="${row3.UpperTier}" />
</sql:query>
<c:forEach var="row4" items="${result4.rows}">
${row4.UpperTier}
<c:choose>
<c:when test="${row4.UpperTier!='NA'}">
<sql:query var="result5" dataSource="${dataSource}">
select * from testinzigzag
where Name like ?
<sql:param value="${row4.UpperTier}" />
</sql:query>
<c:forEach var="row5" items="${result5.rows}">
${row5.UpperTier}
</c:forEach>
</c:when>
</c:choose>
</c:forEach>
</c:when>
</c:choose>
</c:forEach>
</c:when>
</c:choose>
<!-- End: You will have to end the coding part here -->
</c:when>
<c:when test="${row2.UpperTier=='NA'}">
No Upper Tier
</c:when>
</c:choose>
</c:forEach>
</c:when>
</c:choose>

Sorry for the doublepost, continuing from the last post
I can only code it in a way that it is not done in a loop. Assuming i have 50 tiers, I would not to do it 50 times. Is there a way that I can do it in a loop?
