Add LIMIT query in php - php

Question

How can I add LIMIT query in it? I have adding it in
$SQL = "SELECT * FROM eins_policy LIMIT 500 ";
but it did not display the list.
For example:
If I choose 500 records per page;
Total records is 3560 records;
If now I on page 1, meaning (Page number – 1) * 500 = 0, and my Offset is 0;
If now I on page 2, meaning (Page number – 1) * 500 = (2 – 1) * 500 = 500, and Offset is 500, meaning 501 to 1000 is the records fetched;
If now I on page 3, meaning (Page number – 1) * 500 = (3 – 1) * 500 = 1000, and Offset is 1000, meaning 1001 to 1500 is the records fetched;
policylist.php
function eins_listPolicy($page, $record ,$search)
{
//connect to database
base_connectDatabase();
$searchs = explode(" ", $search);
$SQL = "SELECT * FROM eins_policy ";
$countSearch = 0;
foreach ($searchs as &$value) {
if ($countSearch == 0) {
$SQL .= "WHERE ";
} else {
$SQL .= "AND ";
}
$SQL .= "(eins_plcy_code LIKE '%".$value."%' OR
eins_plcy_client IN (SELECT eins_clnt_id FROM eins_client WHERE eins_clnt_full_name LIKE '%".$value."%') OR
eins_plcy_insurance_company IN (SELECT eins_icomp_id FROM eins_insurance_company WHERE eins_icomp_name LIKE '%".$value."%') OR
eins_plcy_agent IN (SELECT eins_agent_id FROM eins_agent WHERE eins_agent_user_id IN (SELECT base_u_id FROM base_users WHERE base_u_name LIKE '%".$value."%')) OR
eins_plcy_policy_type IN (SELECT base_u_id FROM base_users WHERE base_u_name LIKE '%".$value."%') OR
eins_plcy_start_date LIKE '%".$value."%' OR
eins_plcy_end_date LIKE '%".$value."%' OR
eins_plcy_payment_status = '".$value."' OR
eins_plcy_status LIKE '%".$value."%')
";
$countSearch ++;
}
$result = base_executeSQL($SQL);
$total = base_num_rows($result);
if(is_int($total/$record)) {
$tpages = $total/$record;
} else {
$tpages = floor($total/$record)+1;
}
$start = $record * ($page-1);
$adjacents = 3;
$reload = 'policy_list.php';
$count = 0;
$zeroRecord = false;
$RSQL = "LIMIT ".$start.", ".$record."";
$getPolicySQL = base_executeSQL($SQL.$RSQL);
while($Policy_row = base_fetch_array($getPolicySQL))
if (base_num_rows($getPolicySQL)!= 0) {
$inscompName = eins_getInscompDetail($Policy_row["eins_plcy_insurance_company"]);
$agentName = eins_getAgentDetail($Policy_row["eins_plcy_agent"]);
$clientName = eins_getClientDetail($Policy_row["eins_plcy_client"]);
$polocytypeName = eins_getPolicytypeDetail($Policy_row["eins_plcy_policy_type"]);
$count = $count + 1;
echo "<tr>";
echo "<td>". $count ."</td>";
echo "<td>". $Policy_row["eins_plcy_code"] ."</td>";
echo "<td>". $polocytypeName['eins_ptype_name'] ."</td>";

echo "</tr>";
}
if (base_num_rows($getPolicySQL)== 0) {
echo "<tr><td colspan = \"9\" align = \"center\">There is no record!</td></tr>";
$zeroRecord = true;
}
if($zeroRecord == false) {
echo "<tfoot bgcolor=\"white\">";
echo "<tr>";
echo "<td colspan=\"10\">";
$record .= "&search=".$search;
eins_paginate($reload, $page, $tpages, $adjacents, $record, $total) ;
echo "</td>";
echo "</tr>";
}
//close the database
base_closeDatabase();
}

Answer 1

The correct usage of LIMIT is LIMIT offset, max rows
First 500 rows : ... LIMIT 0,500
The next 500: ... LIMIT 500,500 and so on.
