Public Instance methods

Return instance of Sequel::ADO::MSSQL::Dataset with the given opts.

[Source]

    # File lib/sequel/adapters/ado/mssql.rb, line 15
15:         def dataset(opts=nil)
16:           Sequel::ADO::MSSQL::Dataset.new(self, opts)
17:         end

execute_ddl(sql, opts={})

Just execute so it doesn‘t attempt to return the number of rows modified.

[Source]

    # File lib/sequel/adapters/ado/mssql.rb, line 20
20:         def execute_ddl(sql, opts={})
21:           execute(sql, opts)
22:         end

execute_dui(sql, opts={})

Issue a separate query to get the rows modified. ADO appears to use pass by reference with an integer variable, which is obviously not supported directly in ruby, and I‘m not aware of a workaround.

    # File lib/sequel/adapters/ado/mssql.rb, line 28
28:         def execute_dui(sql, opts={})
29:           return super unless @opts[:provider]
30:           synchronize(opts[:server]) do |conn|
31:             begin
32:               log_yield(sql){conn.Execute(sql)}
33:               res = log_yield(ROWS_AFFECTED){conn.Execute(ROWS_AFFECTED)}
34:               res.getRows.transpose.each{|r| return r.shift}
35:             rescue ::WIN32OLERuntimeError => e
36:               raise_error(e)
37:             end
38:           end
39:         end
