Saprfc table with filter

Question

我是新的php saprfc。我使用我們的集成函數，但現在我需要讀取表格中的行。但是我怎麼做只讀幾行，按照一個標準過濾結果，因爲這個表有幾百萬行。

可能嗎？

這是最近使用的代碼部分，在很大的表格上也可以很好地工作。我希望它也能幫助別人。

//Try to connect to SAP using our Login array 
    $rfc = saprfc_open ($saplogin); 
    IF (! $rfc) { ECHO "The RFC connection has failed with the following error:".saprfc_error();EXIT; } 
    //We must know if the function really exists 
    $fce = saprfc_function_discover($rfc, "RFC_READ_TABLE"); 
    IF (! $fce) { ECHO "The function module has failed.";ECHO $rfc;EXIT; } 
    //Convert to uppercase the name of the table to show 
    $Table = "HERE_THE_TABLE_NAME"; 
    //Pass import parameters 
    saprfc_import ($fce,"QUERY_TABLE",$Table);saprfc_import ($fce,"DELIMITER","/"); 
    //Pass table parameters 
    saprfc_table_init ($fce,"OPTIONS"); 
    saprfc_table_append ($fce,"OPTIONS", array ("TEXT"=>"TABLE_FIELD_NAME = '{$input}'")); //input field, filter by this variable 
    saprfc_table_init ($fce,"FIELDS"); 
    saprfc_table_append ($fce,"FIELDS", array ("FIELDNAME"=>"INT_UI")); //wanted answer field 
    saprfc_table_init ($fce,"DATA"); 
    //Call and execute the function 
    $rc = saprfc_call_and_receive ($fce); 
    if ($rc != SAPRFC_OK) 
     { 
     if ($rfc == SAPRFC_EXCEPTION) { echo ("Exception raised: ".saprfc_exception($fce)); } 
     else { echo ("Call error: ".saprfc_error($fce)); } 
     exit; 
     } 
    //Fetch the data from the internal tables 
    $data_row = saprfc_table_rows ($fce,"DATA");$field_row = saprfc_table_rows ($fce,"FIELDS"); 
    for($i=1; $i<=$data_row ; $i++) 
    { $DATA[$i] = saprfc_table_read ($fce,"DATA",$i);$TEST[] = SPLIT("/",$DATA[$i]['WA']); } // get the rows to $TEST variable 


    //release the function and close the connection 
    saprfc_function_free($fce);
