SQLite doesn't support a NOT LIKE b, you need to use NOT (a LIKE b). It doesn't support xor or the extract function natively, so those have to be emulated.

    # File lib/sequel/adapters/shared/sqlite.rb, line 537
    def complex_expression_sql_append(sql, op, args)
      case op
      when :"NOT LIKE", :"NOT ILIKE"
        sql << NOT_SPACE
        complex_expression_sql_append(sql, (op == :"NOT ILIKE" ? :ILIKE : :LIKE), args)

    end

constant_sql_append(sql, constant) click to toggle source

SQLite has CURRENT_TIMESTAMP and related constants in UTC instead of in localtime, so convert those constants to local time.

    # File lib/sequel/adapters/shared/sqlite.rb, line 557
    def constant_sql_append(sql, constant)
      if c = CONSTANT_MAP[constant]
        sql << c
      else
        super
      end
    end

delete() click to toggle source

SQLite performs a TRUNCATE style DELETE if no filter is specified. Since we want to always return the count of records, add a condition that is always true and then delete.

    # File lib/sequel/adapters/shared/sqlite.rb, line 568
    def delete
      @opts[:where] ? super : where(1=>1).delete
    end

explain(opts=nil) click to toggle source

Return an array of strings specifying a query explanation for a SELECT of the current dataset. Currently, the options are ignore, but it accepts options to be compatible with other adapters.

    # File lib/sequel/adapters/shared/sqlite.rb, line 575
    def explain(opts=nil)
      # Load the PrettyTable class, needed for explain output
      Sequel.extension(:_pretty_table) unless defined?(Sequel::PrettyTable)

      ds = db.send(:metadata_dataset).clone(:sql=>"EXPLAIN #{select_sql}")
      rows = ds.all
      Sequel::PrettyTable.string(rows, ds.columns)
    end

having(*cond) click to toggle source

HAVING requires GROUP BY on SQLite

    # File lib/sequel/adapters/shared/sqlite.rb, line 585
    def having(*cond)
      raise(InvalidOperation, "Can only specify a HAVING clause on a grouped dataset") unless @opts[:group]
      super
    end

quoted_identifier_append(sql, c) click to toggle source

SQLite uses the nonstandard ` (backtick) for quoting identifiers.

    # File lib/sequel/adapters/shared/sqlite.rb, line 591
    def quoted_identifier_append(sql, c)
      sql << BACKTICK << c.to_s.gsub(BACKTICK_RE, DOUBLE_BACKTICK) << BACKTICK
    end

select(*cols) click to toggle source

When a qualified column is selected on SQLite and the qualifier is a subselect, the column name used is the full qualified name (including the qualifier) instead of just the column name. To get correct column names, you must use an alias.

    # File lib/sequel/adapters/shared/sqlite.rb, line 599
    def select(*cols)
      if ((f = @opts[:from]) && f.any?{|t| t.is_a?(Dataset) || (t.is_a?(SQL::AliasedExpression) && t.expression.is_a?(Dataset))}) || ((j = @opts[:join]) && j.any?{|t| t.table.is_a?(Dataset)})
        super(*cols.map{|c| alias_qualified_column(c)})
      else
        super
      end
    end

supports_cte?(type=:select) click to toggle source

SQLite 3.8.3+ supports common table expressions.

    # File lib/sequel/adapters/shared/sqlite.rb, line 608
    def supports_cte?(type=:select)
      db.sqlite_version >= 30803
    end

supports_derived_column_lists?() click to toggle source

SQLite does not support table aliases with column aliases

    # File lib/sequel/adapters/shared/sqlite.rb, line 613
    def supports_derived_column_lists?
      false
    end

supports_intersect_except_all?() click to toggle source

SQLite does not support INTERSECT ALL or EXCEPT ALL

    # File lib/sequel/adapters/shared/sqlite.rb, line 618
    def supports_intersect_except_all?
      false
    end

supports_is_true?() click to toggle source

SQLite does not support IS TRUE

    # File lib/sequel/adapters/shared/sqlite.rb, line 623
    def supports_is_true?
      false
    end

supports_multiple_column_in?() click to toggle source

SQLite does not support multiple columns for the IN/NOT IN operators

    # File lib/sequel/adapters/shared/sqlite.rb, line 628
    def supports_multiple_column_in?
      false
    end

supports_timestamp_timezones?() click to toggle source

SQLite supports timezones in literal timestamps, since it stores them as text. But using timezones in timestamps breaks SQLite datetime functions, so we allow the user to override the default per database.

    # File lib/sequel/adapters/shared/sqlite.rb, line 635
    def supports_timestamp_timezones?
      db.use_timestamp_timezones?
    end

supports_where_true?() click to toggle source

SQLite cannot use WHERE 't'.

    # File lib/sequel/adapters/shared/sqlite.rb, line 640
    def supports_where_true?
      false
    end
