Hi all.
I will create procedure by sql query and have @name_table (nvarchar).
How do one procedure using for multiple table not use "EXCE"
example:

SQL

CREATE TABLE tbl_produces
(
   id int primary key,
   name nvarchar(250),
)

GO
INSERT INTO tbl_produces VALUES (1,'abc'),(2,'cde'),(3,'hfd')

GO
CREATE PROCEDURE return_table
(
    @table_name nvarchar(250)
)
AS
  SELECT * FROM @table_name  
Return

GO
" EXCE return_table 'tbl_produces' " = " SELECT * FROM tbl_produces "

How do i can use that? Help me ! Thank for help

Solution 1

Try this:

SQL

CREATE PROCEDURE return_table
    @table_name nvarchar(250)
AS
BEGIN
    DECLARE @sql NVARCHAR(MAX)  

    SET @sql = N'SELECT * FROM ' + @table_name
    EXEC(@sql)
END

Can see if you use query

SQL

CREATE PROCEDURE return_table
(
   @table_name_ nvarchar(250)
)
AS
  DECLARE @sqlStr nvarchar(max) ,
          @ParmDefinition nvarchar(MAX) 
  Set @sqlStr = 'SELECT * FROM @table_name' 
  SET @ParmDefinition = N'@table_name nvarchar(250),
  EXECUTE sp_executesql @sqlStr,
                        @ParmDefinition,
                        @table_name = @table_name_
  RETURN
  GO

for multiple table when i want create 1 function

SQL

CREATE FUNCTION [dbo].[return] ( ) 
RETURNS  TABLE 
AS
RETURN
(
	select * from 
	( 
       SELECT 'EXEC return_table ''tblProduct_01''' AS sp_executesql
       UNION ALL 
	SELECT 'EXEC return_table ''tblProduct_02''' AS sp_executesql	 
) AS T
)
GO

I is fail
