Uses CROSS APPLY to join the given table into the current dataset.

    # File lib/sequel/adapters/shared/mssql.rb
590 def cross_apply(table)
591   join_table(:cross_apply, table)
592 end
disable_insert_output() click to toggle source

Disable the use of INSERT OUTPUT

    # File lib/sequel/adapters/shared/mssql.rb
595 def disable_insert_output
596   clone(:disable_insert_output=>true)
597 end
escape_like(string) click to toggle source

MSSQL treats [] as a metacharacter in LIKE expresions.

600 def escape_like(string)
601   string.gsub(/[\\%_\[\]]/){|m| "\\#{m}"}
602 end
insert_select(*values) click to toggle source

Insert a record, returning the record inserted, using OUTPUT. Always returns nil without running an INSERT statement if disable_insert_output is used. If the query runs but returns no values, returns false.

    # File lib/sequel/adapters/shared/mssql.rb
613 def insert_select(*values)
614   return unless supports_insert_select?
615   with_sql_first(insert_select_sql(*values)) || false

627   clone(:into => table)
628 end
mssql_unicode_strings() click to toggle source

Use the database’s mssql_unicode_strings setting if the dataset hasn’t overridden it.

    # File lib/sequel/adapters/shared/mssql.rb
541 def mssql_unicode_strings
542   opts.has_key?(:mssql_unicode_strings) ? opts[:mssql_unicode_strings] : db.mssql_unicode_strings
543 end
nolock() click to toggle source

Allows you to do a dirty read of uncommitted data using WITH (NOLOCK).

    # File lib/sequel/adapters/shared/mssql.rb
631 def nolock
632   lock_style(:dirty)
633 end
outer_apply(table) click to toggle source

Uses OUTER APPLY to join the given table into the current dataset.

    # File lib/sequel/adapters/shared/mssql.rb
636 def outer_apply(table)
637   join_table(:outer_apply, table)
638 end
output(into, values) click to toggle source

Include an OUTPUT clause in the eventual INSERT, UPDATE, or DELETE query.

The first argument is the table to output into, and the second argument is either an Array of column values to select, or a Hash which maps output column names to selected values, in the style of insert or update.

Output into a returned result set is not currently supported.

Examples:

dataset.output(:output_table, [Sequel[:deleted][:id], Sequel[:deleted][:name]])
dataset.output(:output_table, id: Sequel[:inserted][:id], name: Sequel[:inserted][:name])
    # File lib/sequel/adapters/shared/mssql.rb

655   case values
656   when Hash
657     output[:column_list], output[:select_list] = values.keys, values.values
658   when Array
659     output[:select_list] = values
660   end
661   output[:into] = into
662   clone(:output => output)
663 end
quoted_identifier_append(sql, name) click to toggle source

MSSQL uses [] to quote identifiers.

    # File lib/sequel/adapters/shared/mssql.rb
666 def quoted_identifier_append(sql, name)
667   sql << '[' << name.to_s.gsub(/\]/, ']]') << ']'
668 end
returning(*values) click to toggle source

Emulate RETURNING using the output clause. This only handles values that are simple column references.

    # File lib/sequel/adapters/shared/mssql.rb
671 def returning(*values)
672   values = values.map do |v|
673     unless r = unqualified_column_for(v)
674       raise(Error, "cannot emulate RETURNING via OUTPUT for value: #{v.inspect}")
675     end
676     r
677   end
678   clone(:returning=>values)
679 end
select_sql() click to toggle source

On MSSQL 2012+ add a default order to the current dataset if an offset is used. The default offset emulation using a subquery would be used in the unordered case by default, and that also adds a default order, so it’s better to just avoid the subquery.

    # File lib/sequel/adapters/shared/mssql.rb
685 def select_sql
686   if @opts[:offset]
687     raise(Error, "Using with_ties is not supported with an offset on Microsoft SQL Server") if @opts[:limit_with_ties]

Protected Instance Methods

_import(columns, values, opts=OPTS) click to toggle source

If returned primary keys are requested, use OUTPUT unless already set on the dataset. If OUTPUT is already set, use existing returning values. If OUTPUT is only set to return a single columns, return an array of just that column. Otherwise, return an array of hashes.

Calls superclass method
    # File lib/sequel/adapters/shared/mssql.rb
794 def _import(columns, values, opts=OPTS)
795   if opts[:return] == :primary_key && !@opts[:output]
796     output(nil, [SQL::QualifiedIdentifier.new(:inserted, first_primary_key)])._import(columns, values, opts)

803   else
804     super
805   end
806 end
compound_from_self() click to toggle source

If the dataset using a order without a limit or offset or custom SQL, remove the order. Compounds on Microsoft SQL Server have undefined order unless the result is specifically ordered. Applying the current order before the compound doesn’t work in all cases, such as when qualified identifiers are used. If you want to ensure a order for a compound dataset, apply the order after all compounds have been added.

Calls superclass method
    # File lib/sequel/adapters/shared/mssql.rb
815 def compound_from_self
816   if @opts[:offset] && !@opts[:limit] && !is_2012_or_later?

860   end
861 end
