選擇* mssql + php

Question

我想顯示結果：

require 'connection.php';
$connectionInfo = array("UID" => $usr, "PWD" => $pwd, "Database" => $db);

$conn = sqlsrv_connect($serverName, $connectionInfo);
$tsql = "SELECT * FROM tadatable";    

/* Execute the query. */    

$stmt = sqlsrv_query( $conn, $tsql);    

if ( $stmt )    
{    
       $id = $stmt['id']; 
      echo"<td>".$stmt['name']."</td>"; 
}     echo"<td>".$stmt['name2']."</td>"; 
else     
{    
     echo "Error in statement execution.\n";    
     die( print_r( sqlsrv_errors(), true));    
}    

sqlsrv_free_stmt( $stmt);    
sqlsrv_close( $conn);

沒有執行數據。 只是空白頁，您能看看有什么問題嗎？ MSSQL / PHP /正常工作...

Answer 1

sqlsrv_query
返回成功的語句資源，如果發生錯誤則返回FALSE。

使用sqlsrv_query成功執行查詢后，可以使用sqlsrv_fetch_array或使用sqlsrv_fetch_array直接獲取第一個結果來獲取結果。

$stmt = sqlsrv_query( $conn, $tsql);   
if($stmt === false) {
    die( print_r( sqlsrv_errors(), true) );
}
// loop results with `sqlsrv_fetch_array`
while( $row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC) ) {
    echo $row['id'].", ".$row['name'].", ".$row['name2']."<br />";
}

Answer 2

我覺得您錯過了可滾動數組。

更改以下行。

$stmt = sqlsrv_query( $conn, $tsql, array(), array( "Scrollable" => 'static' ));

Answer 3

<?php  
require 'connection.php';

//$serverName = "(local)";

$connectionInfo = array("UID" => $usr, "PWD" => $pwd, "Database" => $db);  
$conn = sqlsrv_connect( $serverName, $connectionInfo);

if( $conn === false ){  
 echo "Could not connect.\n";  
 die( print_r( sqlsrv_errors(), true));  
}  


$tsql = "SELECT * FROM tadatable";

if( sqlsrv_query( $conn, $tsql))  
{  
      //echo "Statement executed.";  

 while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_ASSOC) ) {
     echo $row['id'].", ".$row['name'].", ".$row['name2']."<br />";
   }

}   
else  
{  
      echo "Error in statement execution.\n";  
      die( print_r( sqlsrv_errors(), true));  
}  


sqlsrv_close($conn);  
?>
