Here i have an usable code for all u:



   I wanted to know if a field is nullable or if it's defined as a primary key, here are those functions definitions:



*Aditional Notes:

    if any of the tables are replicated in another database exactly , this code will not work well.



//-----to know if a field is nullable-------

function mssql_field_nullable($ip,$user,$pass,$table,$field)//starting from 1st field

{

      $conn=mssql_connect($ip,$user,$pass)or die;

      mssql_select_db('master');

      $result=mssql_query("SELECT syscolumns.isnullable

FROM sysobjects INNER JOIN

    syscolumns ON sysobjects.id = syscolumns.id WHERE sysobjects.name ='$table' AND syscolumns.isnullable = 1");

      $x=mssql_num_rows($result);

      mssql_close($conn);

      return ($x==1?1:0);



}

//-------to know if a field is a primary key-------

function mssql_field_key($ip,$user,$pass,$table,$field)//starting from 1st field

{

      $conn=mssql_connect($ip,$user,$pass)or die;

      mssql_select_db('master');

      $result=mssql_query("SELECT sysindexkeys.colid FROM sysobjects INNER JOIN sysindexkeys ON sysobjects.id = sysindexkeys.id WHERE sysobjects.name ='$table' AND sysindexkeys.colid = $field");

      $x=mssql_num_rows($result);

      mssql_close($conn);

      return ($x==1?1:0);



}
