In this article, I am going to explain how to call a stored procedure that accepts custom-defined table types. If you have to send multiple records in a single time to the DB from your front end, that's where we use custom defined table types.

These types allow multiple rows, which contain different data types like varchar, boolean, etc.

I have a table type below:

    SQL
   
 

     
    
x

            
          
USE [myown] GO 
/****** Object: UserDefinedTableType [dbo].[tblcustomers] Script Date: 6/2/2018 4:11:08 PM ******/
create TYPE [dbo].[tblcustomers] AS TABLE(
  [Title] [nvarchar](8) NULL, 
  [Suffix] [nvarchar](10) NULL, 
  [CompanyName] [nvarchar](128) NULL, 
  [SalesPerson] [nvarchar](256) NULL, 
  [EmailAddress] [nvarchar](50) NULL, 
  [PasswordHash] [nvarchar](128) NOT NULL, 
  [PasswordSalt] [nvarchar](10) NOT NULL
) GO

A stored procedure, which has table typed parameter is as follows:

    SQL
   
xxxxxxxxxx

USE [myown] GO create PROCEDURE [dbo].[fetchtblCusomters](
  @tblcustomers tblcustomers READONLY
) AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON -- Insert statements for procedure here select * from @tblcustomers END

Now we have to call this stored procedure in Mule, and my flow looks like below:

    </flow>
</mule> 

Mule Steps

Create a flow Variable object for the class SQLServerDataTable
Add columns to the table type object you have created.
1. records.addColumnMetadata("Suffix" ,java.sql.Types.NVARCHAR); — In here, Suffix is a column table and it is NVARCHAR SQL type
2. Once you are done adding columns, add rows to the table
  1. records.addRow('Dr', 'Hr', 'Mindtree', 'tiptpop', 'helllo.rai@gmai.com', '', '');
3. Now, using database connector, call the Stored Procedure, which has table type parameter.

Your SQL Server DB connection will be:

That's it, you have your multiple records flying through to SQL Server DB in a single time.
