sql - Stored Procedure cant detect SET? -

-

im trying make stored procedure reads different .dbf files every time execute it, making dynamic stored procedure. problem is, im not in sql yet , im having errors. error:

procedure or function 'readdbf' expects parameter '@sql', not supplied.

i know missing and/or making makes stored procedure not understand please can point in in right direction?

this code:

`

use devssis  go  exec master.dbo.sp_msset_oledb_prop n'vfpoledb', n'allowinprocess', 1  go create procedure readdbf ( @path nvarchar(1000), @name nvarchar(50), @sql varchar(max) ) begin set @sql = 'select * openrowset(''vfpoledb.1'', ''' + @path +'''; ''; '', ''select * ''' + @name + ''')' end exec @sql go

`

im using sql 2005 btw

i suspect want define @sql local variable in stored procedure, not parameter:

create procedure readdbf (   @path nvarchar(1000),   @name nvarchar(50) ) begin     declare @sql nvarchar(max)     set @sql = 'select * openrowset(''vfpoledb.1'', ''' + @path +'''; ''; '', ''select * ''' + @name + ''')';     exec(@sql); end;

if learning dynamic sql, should learning use sp_executesql rather exec.

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
