If you want to return more than 1 value use this:

DECLARE @sqlstatement2      NVARCHAR(MAX);
DECLARE @retText            NVARCHAR(MAX);  
DECLARE @ParmDefinition     NVARCHAR(MAX);
DECLARE @retIndex           INT = 0;

SELECT @sqlstatement = 'SELECT @retIndexOUT=column1 @retTextOUT=column2 FROM XXX WHERE bla bla';

SET @ParmDefinition = N'@retIndexOUT INT OUTPUT, @retTextOUT NVARCHAR(MAX) OUTPUT';

exec sp_executesql @sqlstatement, @ParmDefinition, @retIndexOUT=@retIndex OUTPUT, @retTextOUT=@retText OUTPUT;

returned values are in @retIndex and @retText
