How do I Pass a parameter to a SQL Component Task where the source SQL statement is also a variable

Hi,

I have been tasked with making a complex package more generic.

To achieve this I need to pass a parameter to a SQL Component Task where the source SQL statement is also a variable.

So to help articulate my question further I have create a package and database as follows; -

USE [KWPlay]
GO
/****** Object:  Table [dbo].[tblTest]    Script Date: 05/14/2014 17:08:02 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[tblTest](
	[ID] [bigint] IDENTITY(1,1) NOT NULL,
	[Description] [nvarchar](50) NULL,
 CONSTRAINT [PK_tblTest] PRIMARY KEY CLUSTERED 
(
	[ID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

I populated this table with a single record.

I unit tested the SQL within SSMS as follows;

SELECT * FROM dbo.tblTest

Result; -

ID            Description

1             Happy

DECLARE @myParam NVARCHAR(100)
SET @myParam = 'Sad'
UPDATE dbo.tblTest SET [Description] = @myParam FROM dbo.tblTest WHERE ID = 1
SELECT * FROM dbo.tblTest

Result; -

ID   Description

1    Sad

Within the package I created two variables as follows; -

Name: strSQL

Scope: Package

Data Type: String

Value: UPDATE dbo.tblTest SET [Description] = @myParam FROM dbo.tblTest WHERE ID = 1

Name: strStatus

Scope: Package

Data Type: String

Value: Happy

I then created a single ‘Execute SQL Task’ component within the control flow as follows; -

However when I run the above package I get the following error; -

SSIS package "Package.dtsx" starting.

Error: 0xC002F210 at Execute SQL Task, Execute SQL Task: Executing the query "UPDATE dbo.tblTest SET [Description] = @myParam FR..." failed with the following error:"Parameter name is unrecognized.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

Task failed: Execute SQL Task

Warning: 0x80019002 at Package: SSIS Warning Code DTS_W_MAXIMUMERRORCOUNTREACHED. The Execution method succeeded, but the number of errors raised (1) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.

SSIS package "Package.dtsx" finished: Failure.

I also tried; - 

Name: strSQL

Scope: Package

Data Type: String

Value: UPDATE dbo.tblTest SET [Description] = ? FROM dbo.tblTest WHERE ID = 1

However I received the error; - 

SSIS package "Package.dtsx" starting.
Error: 0xC002F210 at Execute SQL Task, Execute SQL Task: Executing the query "UPDATE dbo.tblTest SET [Description] = ? FROM dbo...." failed with the following error: "Parameter name is unrecognized.".

Kind Regards,
