Exemple #1 Exemple avec mssql_field_type()


<?php
// Connexion à MSSQL et sélection de la base de données
mssql_connect('MANGO\SQLEXPRESS', 'sa', 'phpfi');
mssql_select_db('php');

// Envoi d'une requête MSSQL
$query = mssql_query('SELECT [name] FROM [php].[dbo].[persons]');

// Affiche le type de champ et sa taille
echo '\'' . mssql_field_name($query, 0) . '\' est de type ' . 
     strtoupper(mssql_field_type($query, 0)) . 
     '(' . mssql_field_length($query, 0) . ')';

// Libère le résultat
mssql_free_result($query);

If you need a more detailed discription of your column type,



This query shows your true datatypes like:



binary => binary 

varbinary => varbinary 

varchar => varchar 

bit => bit

char => char

datetime => datetime

smalldatetime => smalldatetime 

decimal => decimal 

real => real

tinyint => tinyint 

smallint => smallint 

smallmoney => smallmoney 

money => money

nchar => nchar 

ntext => ntext 

text => text

numeric => numeric

nvarchar => nvarchar 

 



SELECT     sysobjects.name AS tableName, syscolumns.name AS columnName, systypes.name AS columnType

FROM         sysobjects INNER JOIN

                      syscolumns ON sysobjects.id = syscolumns.id INNER JOIN

                      systypes ON syscolumns.type = systypes.type AND syscolumns.xusertype = systypes.xusertype

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);



}
