If you have OUTPUT parameters you can do  DECLARE  retval int    DECLARE  sSQL nvarchar 500   DECLARE  ParmDefinition nvarchar 500    DECLARE  tablename nvarchar 50    SELECT  tablename   N products     SELECT  sSQL   N SELECT  retvalOUT   MAX ID  FROM      tablename    SET  ParmDefinition   N  retvalOUT int OUTPUT    EXEC sp executesql  sSQL   ParmDefinition   retvalOUT  retval OUTPUT   SELECT  retval    But if you don t  and can not modify the SP   -- Assuming that your SP return 1 value create table  temptable  ID int null  insert into  temptable exec mysp  Value1    Value2  select   from  temptable   Not pretty  but works

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

This was a long time ago  so not sure if this is still needed  but you could use   ROWCOUNT variable to see how many rows were affected with the previous sql statement    This is helpful when for example you construct a dynamic Update statement and run it with exec    ROWCOUNT would show how many rows were updated   Here is the definition

Here s something you can try  DECLARE   SqlStatement  NVARCHAR MAX                result     XML          DatabaseName  VARCHAR 100           SchemaName    VARCHAR 10           ObjectName    VARCHAR 200    SELECT    DatabaseName    some database           SchemaName      some schema           ObjectName      some object  Table View    SET  SqlStatement                         SELECT  result   CONVERT XML                                              STUFF    SELECT                                                        FROM                                                                                                                     SELECT TOP 100                                                                                                                          FROM     QUOTENAME  DatabaseName        QUOTENAME  SchemaName         QUOTENAME  ObjectName                                                               AS A1                                                      FOR XML PATH   row     ELEMENTS  ROOT   recordset                                                        1  0                                                                     EXEC sp executesql  SqlStatement N  result XML OUTPUT    result    result OUTPUT   SELECT DISTINCT     QUOTENAME r value  fn local-name       VARCHAR 200     AS ColumnName FROM  result nodes    recordset       AS records r  ORDER BY ColumnName

Return values are generally not used to  return  a result but to return success  0  or an error number  1-65K   The above all seem to indicate that sp executesql does not return a value  which is not correct  sp executesql will return 0 for success and any other number for failure   In the below   i will return 2727  DECLARE  s NVARCHAR 500  DECLARE  i INT  SET  s    USE  Blah   UPDATE STATISTICS  dbo   TableName   NonExistantStatisticsName     EXEC  i   sys sp executesql  s SELECT  i AS  Blah    SSMS will show this Msg 2727  Level 11  State 1  Line 1 Cannot find index  NonExistantStaticsName
