Question

I am using C# to write a method that returns the following information about a table: column names, column types, column sizes, foreign keys.

Can someone point me in the right direction on how to accomplish this ?

Answer 1

To get the FK and Schema you should be able to use:

DA.FillSchema()   DS.Table('Name').PrimaryKey  

OR calling sp_fkey using the method demonstrated below

Code Snippet from AND Another Link

    private void LoanSchema()     {           private List<String> tablesList = new List<String>();          private Dictionary<String, String> columnsDictionary = new Dictionary<String, String>();            string connectionString = 'Integrated Security=SSPI;' +           'Persist Security Info = False;Initial Catalog=Northwind;' +           'Data Source = localhost';           SqlConnection connection = new SqlConnection();           connection.ConnectionString = connectionString;           connection.Open();            SqlCommand command = new SqlCommand();           command.Connection = connection;           command.CommandText = 'exec sp_tables';           command.CommandType = CommandType.Text;            SqlDataReader reader = command.ExecuteReader();             if (reader.HasRows)            {                while (reader.Read())                   tablesList.Add(reader['TABLE_NAME'].ToString());            }            reader.Close();             command.CommandText = 'exec sp_columns @table_name = '' +            tablesList[0] + ''';            command.CommandType = CommandType.Text;            reader = command.ExecuteReader();              if (reader.HasRows)             {                 while (reader.Read())                           columnsDictionary.Add(reader['COLUMN_NAME'].ToString(), reader['TYPE_NAME'].ToString());              } }
