SQL server stored procedure return a table

Question

I have a stored procedure that takes in two parameters  I can execute it successfully in Server Management Studio  It shows me the results which are as I expect  However it also returns a Return Value   It has added this line    SELECT  Return Value     return value   I would like the stored procedure to return the table it shows me in the results not the return value as I am calling this stored procedure from MATLAB and all it returns is true or false   Do I need to specify in my stored procedure what it should return  If so how do I specify a table of 4 columns  varchar 10   float  float  float

I had a similar situation and solved by using a temp table inside the procedure  with the same fields being returned by the original Stored Procedure   CREATE PROCEDURE mynewstoredprocedure AS  BEGIN  INSERT INTO temptable  field1  field2  EXEC mystoredprocedure  param1   param2  select field1  field2 from temptable  --  mystoredprocedure returns field1  field2   END

Consider creating a function which can return a table and be used in a query   https   msdn microsoft com en-us library ms186755 aspx  The main difference between a function and a procedure is that a function makes no changes to any table   It only returns a value   In this example I m creating a query to give me the counts of all the columns in a given table which aren t null or empty   There are probably many ways to clean this up   But it illustrates a function well   USE Northwind  CREATE FUNCTION usp listFields  schema VARCHAR 50    table VARCHAR 50   RETURNS  query TABLE       FieldName VARCHAR 255        BEGIN     INSERT  query     SELECT          SELECT        table     RTRIM COLUMN NAME       CONVERT VARCHAR  COUNT             FROM    schema      table                  WHERE isnull    RTRIM COLUMN NAME           lt  gt      UNION      FROM INFORMATION SCHEMA COLUMNS WHERE TABLE NAME    table and TABLE SCHEMA    schema     RETURN END   Then executing the function with   SELECT   FROM usp listFields  Employees     produces a number of rows like   SELECT  Employees EmployeeID   CONVERT VARCHAR  COUNT     FROM dbo Employees  WHERE isnull  EmployeeID      lt  gt    UNION SELECT  Employees LastName   CONVERT VARCHAR  COUNT     FROM dbo Employees  WHERE isnull  LastName      lt  gt    UNION SELECT  Employees FirstName   CONVERT VARCHAR  COUNT     FROM dbo Employees  WHERE isnull  FirstName      lt  gt    UNION

You can use an out parameter instead of the return value if you want both a result set and a return value  CREATE PROCEDURE proc name   param int out AS BEGIN     SET  param   value SELECT     FROM  Table  WHERE Condition END GO

Here s an example of a SP that both returns a table and a return value   I don t know if you need the return the  Return Value  and I have no idea about MATLAB and what it requires     CREATE PROCEDURE test AS  BEGIN      SELECT   FROM sys databases      RETURN 27 END  --Use this to test DECLARE  returnval int  EXEC  returnval   test   SELECT  returnval

The Status Value being returned by a Stored Procedure can only be an INT datatype   You cannot return other datatypes in the RETURN statement   From Lesson 2  Designing Stored Procedures      Every stored procedure can return an integer value known as the   execution status value or return code    If you still want a table returned from the SP  you ll either have to work the record set returned from a SELECT within the SP or tie into an OUTPUT variable that passes an XML datatype   HTH   John

A procedure can t return a table as such  However you can select from a table in a procedure and direct it into a table  or table variable  like this   create procedure p x as begin declare  t table col1 varchar 10   col2 float  col3 float  col4 float  insert  t values  a   1 1 1  insert  t values  b   2 2 2   select   from  t end go  declare  t table col1 varchar 10   col2 float  col3 float  col4 float  insert  t exec p x  select   from  t

I do this frequently using Table Types to ensure more consistency and simplify code  You can t technically return  a table   but you can return a result set and using INSERT INTO    EXEC     syntax  you can clearly call a PROC and store the results into a table type  In the following example I m actually passing a table into a PROC along with another param I need to add logic  then I m effectively  returning a table  and can then work with that as a table variable           Check if my table type and or proc exists and drop them         IF EXISTS  SELECT   FROM sys objects WHERE type    P  AND name    returnTableTypeData   DROP PROCEDURE returnTableTypeData GO IF EXISTS  SELECT   FROM sys types WHERE is table type   1 AND name    myTableType   DROP TYPE myTableType GO          Create the type that I ll pass into the proc and return from it         CREATE TYPE  dbo   myTableType  AS TABLE       someInt   int  NULL       somenVarChar   nvarchar  100  NULL   GO  CREATE PROC returnTableTypeData      someInputInt INT       myInputTable myTableType READONLY --Must be readonly because AS BEGIN      --Return the subset of data consistent with the type     SELECT               FROM          myInputTable     WHERE         someInt  lt   someInputInt  END GO   DECLARE  myInputTableOrig myTableType DECLARE  myUpdatedTable myTableType  INSERT INTO  myInputTableOrig   someInt somenVarChar   VALUES   0  N Value 0       1  N Value 1       2  N Value 2     INSERT INTO  myUpdatedTable EXEC returnTableTypeData  someInputInt 1   myInputTable  myInputTableOrig  SELECT   FROM  myUpdatedTable   DROP PROCEDURE returnTableTypeData GO DROP TYPE myTableType GO
