How to insert data from a select query using php - php

Question

I wan to insert data to mysql table from another database which is connected via ODBC.But I cannot enter into the while loop, here is my code -
N.B: For security I dont provide db name, user and pass.
ODBC connection declared as 'connStr'
<?php
$connStr = odbc_connect("database","user","pass");
$conn = mysqli_connect("server","user","pass","database");
//$result_set=mysqli_query($conn,$datequery);
//$row=mysqli_fetch_array($result_set);
echo "<br>";
echo "<br>";
$query="select cardnumber, peoplename, creditlimit, ROUND(cbalance,2) as cbalance, minpay from IVR_CardMember_Info
where cardnumber not like '5127%'" ;
$rs=odbc_exec($connStr,$query);
$i = 1;
while(odbc_fetch_row($rs))
{ //echo "Test while";
$cardnumber=odbc_result($rs, "cardnumber");
$peoplename=odbc_result($rs, "peoplename");
$creditlimit=odbc_result($rs, "creditlimit");
$cbalance=odbc_result($rs, "cbalance");
$minpay=odbc_result($rs, "minpay");
$conn = mysqli_connect("server","user","pass","database");
$sql= "INSERT INTO test_data(cardnumber, peoplename, creditlimit, cbalance, minpay) VALUES ('cardnumber', 'peoplename', 'creditlimit', 'cbalance', 'minpay') ";
if(!(mysqli_query($conn,$sql))){
//echo "Data Not Found";
echo "<br>";
}
else{
echo "Data Inserted";
echo "<br>";
}
echo $i++ ;
}
echo "<br>";
odbc_close($connStr);
?>
How can I solve this?

Answer 1

If you really want to understand why you can't enter while() {...}, you need to consider the following.
First, your call to odbc_connect(), which expects database source name, username and password for first, second and third parameter. It should be something like this (DSN-less connection):
<?php
...
$connStr = odbc_connect("Driver={MySQL ODBC 8.0 Driver};Server=server;Database=database;", "user", "pass");
if (!$connStr) {
echo 'Connection error';
exit;
}
...
?>
Second, check for errors after odbc_exec():
<?php
...
$rs = odbc_exec($connStr, $query);
if (!$rs) {
echo 'Exec error';
exit;
}
...
?>

you can do it with just SQL check it here, like:
INSERT INTO test_data(cardnumber, peoplename, creditlimit, cbalance, minpay)
SELECT cardnumber, peoplename, creditlimit,
ROUND(cbalance,2) as cbalance, minpay from IVR_CardMember_Info
where cardnumber not like '5127%'
