如何使用 php 从 select 查询中插入数据

How to insert data from a select query using php

我想从另一个通过 ODBC.But 连接的数据库向 mysql table 插入数据 我无法进入 while 循环,这是我的代码 - N.B:为了安全起见,我没有提供数据库名称、用户和密码。 ODBC 连接声明为 '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);

?>

我该如何解决这个问题?

您只需 SQL 即可完成检查 here,例如:

     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%'

如果你真的想明白为什么不能输入while() {...},你需要考虑以下几点。

首先,您调用 odbc_connect(),它需要数据库源名称、用户名和密码作为第一个、第二个和第三个参数。它应该是这样的(无 DSN 连接):

<?php
...
$connStr = odbc_connect("Driver={MySQL ODBC 8.0 Driver};Server=server;Database=database;", "user", "pass");
if (!$connStr) {
    echo 'Connection error';
    exit;
}
...
?>

其次,在odbc_exec():

之后检查错误
<?php
...
$rs = odbc_exec($connStr, $query);
if (!$rs) {
    echo 'Exec error';
    exit;
}
...
?>
