fetch_array中的sqlsvr_fetch_array

Question

So I have a PHP script I am convering from MSSQL to SQLSRV and I am having some difficulty.

I have this

 while($row = sqlsrv_fetch_array($result, SQLSRV_FETCH_ASSOC))
{

$time = time() - strtotime('today');

$row2sql = "SELECT SUM(mnyAmount) AS 'Total' FROM dbo.tblTransactions WHERE intPerson='".$row[intPerson]."'";
$row3sql = "SELECT SUM(mnyAmount) AS 'Total' FROM dbo.tblTransactions WHERE intPerson='".$row[intPerson]."' AND strDate>'".$row[strDate]."' AND mnyAmount<'0'";
$row4sql = "SELECT SUM(mnyAmount) AS 'Total' FROM dbo.tblTransactions WHERE intPerson='".$row[intPerson]."' AND strDate>'".$row[strDate]."' AND mnyAmount>'0'";

$row2 = sqlsrv_fetch_array($row2sql, SQLSRV_FETCH_ASSOC);
$row3 = sqlsrv_fetch_array($row3sql, SQLSRV_FETCH_ASSOC);
$row4 = sqlsrv_fetch_array($row4sql, SQLSRV_FETCH_ASSOC);

Which essentially pulls data based on the search and then cross references their data per row. In MySQL this wouldn't be a problem - but seem to be having difficult here?

Basically, if I search "Smith" it will bring up all users with Smith in their name...(for example three rows) then I want it to get each of their balances respectively.

Can anyone help please?

Thank you.

Answer 1

You're missing the call to sqlsrv_query for each of your queries.

ie you should have something like this for each of your sub queries (see example 1 http://www.php.net/manual/en/function.sqlsrv-fetch-array.php ):

$sql = "SELECT SUM(mnyAmount) AS 'Total' FROM dbo.tblTransactions WHERE intPerson='".$row[intPerson]."'";
$stmt = sqlsrv_query( $conn, $sql );
if( $stmt === false) {
    die( print_r( sqlsrv_errors(), true) );
}

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

sqlsrv_free_stmt( $stmt);

Given that you have used both MySQL and SQLServer, it is probably worth looking at using PDO ( http://uk3.php.net/pdo ). This will allow you to alter configuration instead of having to edit code should you need to change db server. It also makes code consistent.

This would be the fixed code. The first parameter of sqlsrv_fetch_array has to be a resource, you're giving a string here. You have to execute the query first before "unzipping" it.

while($row = sqlsrv_fetch_array($result, SQLSRV_FETCH_ASSOC))
{

$time = time() - strtotime('today');

$row2sql = "SELECT SUM(mnyAmount) AS 'Total' FROM dbo.tblTransactions WHERE intPerson='".$row[intPerson]."'";
$row3sql = "SELECT SUM(mnyAmount) AS 'Total' FROM dbo.tblTransactions WHERE intPerson='".$row[intPerson]."' AND strDate>'".$row[strDate]."' AND mnyAmount<'0'";
$row4sql = "SELECT SUM(mnyAmount) AS 'Total' FROM dbo.tblTransactions WHERE intPerson='".$row[intPerson]."' AND strDate>'".$row[strDate]."' AND mnyAmount>'0'";
//$connection is the connection variable you get from opening a connection to the database
$result2 = sqlsrv_query($connection, $row2sql);
$result3 = sqlsrv_query($connection, $row3sql);
$result4 = sqlsrv_query($connection, $row4sql);
$row2 = sqlsrv_fetch_array($result2, SQLSRV_FETCH_ASSOC);
$row3 = sqlsrv_fetch_array($result3, SQLSRV_FETCH_ASSOC);
$row4 = sqlsrv_fetch_array($result4, SQLSRV_FETCH_ASSOC);
