从查询中检索信息，其中表名和值是参数SQL

Question

I am trying to retrieve a bunch of info from SQL procedure. It should receive two parameters, one of the parameters is a table name and the other is the value properly. Is there any way to retrieve that?

This is the query I've created so far:

CREATE PROCEDURE SP_Positions_Filtered
    @Parameter VARCHAR(200), 
    @Id VARCHAR(50)
AS
    SELECT 
        POSITION.*, 
        COALESCE((SELECT Category.Name 
                  FROM Category 
                  WHERE Category.Id = POSITION.Area), POSITION.Area) AS AreaName, 
        COALESCE((SELECT Country.Name 
                  FROM Country 
                  WHERE Country.Id = POSITION.Country), POSITION.Country) AS CountryName,
        COALESCE((SELECT Department.Name 
                  FROM Department 
                  WHERE Department.Id = POSITION.Department), POSITION.Department) AS DepartmentName,
        COALESCE((SELECT City.Name 
                  FROM City 
                  WHERE City.Id = POSITION.City), POSITION.City) AS CityName,
        COALESCE((SELECT Salary.Data_Range 
                  FROM Salary  
                  WHERE Salary.Id = POSITION.Wage), POSITION.Wage) AS SalaryRange
    FROM 
        POSITION
    WHERE
        (SELECT DISTINCT name FROM sys.columns WHERE name = @Parameter) = @Id

Could somebody help me out with this issue?

Thanks in advance.

You can achieve this using the Dynamic query inside the store procedure. see example below:

CREATE Procedure FC_Sample
@TableName Varchar (100) AS BEGIN DECLARE @query NVARCHAR(MAX); set @query = 'SELECT * from' + ' ' + @TableName EXECUTE sp_executesql @query END

And you can execute the Stored procedure as below:

EXEC FC_Sample 'ACIChemical'

Hope this is what you are looking for.
