Question

I have a table valued function called split in my database and I want to use it in a stored procedure.

When I say entity I mean department in company, as you know companies has department, section and other divisions under each other. When user creates entity it should have parent which is the company or another entity and maybe have a child which is another entity e.g IT>Development>software… etc.

Each one has id. I am storing these ids in one column like this 1,2,1. I need to split them when am showing to users.

Here is my function:

 ALTER FUNCTION [dbo].[Split](@String varchar(50), @Delimiter char(1))       
 returns @temptable TABLE (items varchar(50))       
 as       
 begin       
  declare @idx int       
  declare @slice varchar(50)       

 select @idx = 1       
    if len(@String)<1 or @String is null  return       

 while @idx!= 0       
 begin       
    set @idx = charindex(@Delimiter,@String)       
    if @idx!=0       
        set @slice = left(@String,@idx - 1)       
    else       
        set @slice = @String       

  if(len(@slice)>0)  
        insert into @temptable(Items) values(@slice)       

   set @String = right(@String,len(@String) - @idx)       
    if len(@String) = 0 break       
   end   
  return       
 end

Here is my stored procedure:

alter   procedure [dbo].[Emp_CompanyHirarchy]
@FK_CompanyId varchar(50),
@FK_EntityId varchar(50)
AS
  SELECT     
     Employee.EmployeeId, Employee.EmployeeNo,   
     Employee.EmployeeName, Employee.EmployeeArabicName, 
     OrgEntity.EntityName, OrgCompany.CompanyName, 
     Employee.DOB, Employee.Email
  FROM         
     Employee 
  INNER JOIN
     OrgEntity ON Employee.FK_EntityId = OrgEntity.EntityId 
  INNER JOIN
     OrgCompany ON OrgEntity.FK_CompanyId = OrgCompany.CompanyId
  WHERE     
     (Employee.FK_EntityId IN (dbo.Split(EntityHierarchy)))

Answer 1

In General;

Select items From dbo.Split(YourColumnOrVariable,',')

In your case, (since you are using IN) WHERE clause should be as;

WHERE (Employee.FK_EntityId IN (Select Items FROM dbo.Split(EntityHierarchy)))
--Items is the column name of the returning table
