Alternative for goto

Code:
 
#!/bin/sh
label:
echo sql poll
 v=`sqlplus -s <<!
 HR/HR
 set pages 0 echo off feed off
 select distinct status from
 emp
 where
 id=5;
 !
 `
echo $v;
echo it comes here after false
if [ "$v" -eq 4 ]
then
echo if condition true
sqlplus -l scott/tiger <<EOF
select * from department;
EXIT
EOF
else
   sleep 30;
   goto label
fi


If the condition fails in the above script then it needs to sleep for 30 seconds then go to label and poll the database tabel. I read there is no goto in bourne shell so i tried to use other options like funtions but i could not finish this task. can someone help me to fix this. I tried like below . I am a absolute beginner in shell script so couldnot catch the concepts well.Thanks for your help in advance

Code:
 
#!/bin/sh
start(){
echo sql poll
 v=`sqlplus -s <<!
 HR/HR
 set pages 0 echo off feed off
 select distinct status from
 emp
 where
 id=5;
 !
 `
echo $v;
}
rval=start
if [ "$rval" -eq 4 ]
then
echo if condition true
sqlplus -l scott/tiger <<EOF
select * from department;
EXIT
EOF
else
   sleep 30;
   start
fi

DB2_FETCH_ROW(3)							 1							  DB2_FETCH_ROW(3)

db2_fetch_row - Sets the result set pointer to the next row or requested row

SYNOPSIS
bool db2_fetch_row (resource $stmt, [int $row_number]) DESCRIPTION
Use db2_fetch_row(3) to iterate through a result set, or to point to a specific row in a result set if you requested a scrollable cursor. To retrieve individual fields from the result set, call the db2_result(3) function. Rather than calling db2_fetch_row(3) and db2_result(3), most applications will call one of db2_fetch_assoc(3), db2_fetch_both(3), or db2_fetch_array(3) to advance the result set pointer and return a complete row as an array. PARAMETERS
o $stmt - A valid stmt resource. o $row_number - With scrollable cursors, you can request a specific row number in the result set. Row numbering is 1-indexed. RETURN VALUES
Returns TRUE if the requested row exists in the result set. Returns FALSE if the requested row does not exist in the result set. EXAMPLES
Example #1 Iterating through a result set The following example demonstrates how to iterate through a result set with db2_fetch_row(3) and retrieve columns from the result set with db2_result(3). <?php $sql = 'SELECT name, breed FROM animals WHERE weight < ?'; $stmt = db2_prepare($conn, $sql); db2_execute($stmt, array(10)); while (db2_fetch_row($stmt)) { $name = db2_result($stmt, 0); $breed = db2_result($stmt, 1); print "$name $breed"; } ?> The above example will output: cat Pook gold fish Bubbles budgerigar Gizmo goat Rickety Ride Example #2 i5/OS recommended alternatives to db2_fetch_row/db2_result On i5/OS it is recommended that you use db2_fetch_both(3), db2_fetch_array(3), or db2_fetch_object(3) over db2_fetch_row(3)/db2_result(3). In general db2_fetch_row(3)/db2_result(3) have more issues with various column types in EBCIDIC to ASCII translation, including possible truncation in DBCS applications. You may also find the performance of db2_fetch_both(3), db2_fetch_array(3), and db2_fetch_object(3) to be superior to db2_fetch_row(3)/db2_result(3). <?php $conn = db2_connect("","",""); $sql = 'SELECT SPECIFIC_SCHEMA, SPECIFIC_NAME, ROUTINE_SCHEMA, ROUTINE_NAME, ROUTINE_TYPE, ROUTINE_CREATED, ROUTINE_BODY, IN_PARMS, OUT_PARMS, INOUT_PARMS, PARAMETER_STYLE, EXTERNAL_NAME, EXTERNAL_LANGUAGE FROM QSYS2.SYSROUTINES FETCH FIRST 2 ROWS ONLY'; $stmt = db2_exec($conn, $sql, array('cursor' => DB2_SCROLLABLE)); while ($row = db2_fetch_both($stmt)){ echo "<br>db2_fetch_both {$row['SPECIFIC_NAME']} {$row['ROUTINE_CREATED']} {$row[5]}"; } $stmt = db2_exec($conn, $sql, array('cursor' => DB2_SCROLLABLE)); while ($row = db2_fetch_array($stmt)){ echo "<br>db2_fetch_array {$row[1]} {$row[5]}"; } $stmt = db2_exec($conn, $sql, array('cursor' => DB2_SCROLLABLE)); while ($row = db2_fetch_object($stmt)){ echo "<br>db2_fetch_object {$row->SPECIFIC_NAME} {$row->ROUTINE_CREATED}"; } db2_close($conn); ?> The above example will output: db2_fetch_both MATCH_ANIMAL 2006-08-25-17.10.23.775000 2006-08-25-17.10.23.775000 db2_fetch_both MULTIRESULTS 2006-10-17-10.11.05.308000 2006-10-17-10.11.05.308000 db2_fetch_array MATCH_ANIMAL 2006-08-25-17.10.23.775000 db2_fetch_array MULTIRESULTS 2006-10-17-10.11.05.308000 db2_fetch_object MATCH_ANIMAL 2006-08-25-17.10.23.775000 db2_fetch_object MULTIRESULTS 2006-10-17-10.11.05.308000 SEE ALSO
