What is similar in mssql to $dbh->listfields($tbl) in mysql
You can use the following query to get the columns in a table from MS SQL Server:
select syscolumns.name from syscolumns
join sysobjects on sysobjects.id = syscolumns.id
where sysobjects.name = ?
(you supply the table name as the argument to execute
to provide the data for the placeholder.
Alternatively you can use the INFORMATION_SCHEMA view which basically does the same thing:
select COLUMN_NAME from information_schema.columns
where table_name = ?
