Spring Integration - Stored Procedure Example - Microsoft SQL Server (Express)

Overview

This example provides a simple example using the Stored Procedure Outbound Gateway. This example will call Stored Procedure as well as a User-defined Function using Microsoft SQL Server (Express).

Setup

Pre-requisites

Access to a Microsoft SQL Server or Microsoft SQL Server Express database instance.

This sample was tested against: Microsoft SQL Server 2008 R2 RTM - Express (Which can be downloaded and used for free). The sample should also work for newer versions (including the full version) of Microsoft SQL Server. You can download Microsoft SQL Server Express 2008: SQL Server Express:

• https://www.microsoft.com/en-us/download/details.aspx?id=23650

If you have trouble accessing a remote instance of Microsoft SQL Server Express, see:

• https://support.microsoft.com/default.aspx?scid=kb;EN-US;914277#method2

JDBC Driver

This sample uses the jTDS driver, which is considered to be faster than Microsoft's JDBC driver. Nevertheless, the sample should work with either driver.

Creating the Stored Procedure

USE [your database name]
GO

IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[CAPITALIZE_STRING]') AND type in (N'P', N'PC'))
DROP PROCEDURE [dbo].[CAPITALIZE_STRING]
GO

SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

-- ===========================================================

CREATE PROCEDURE [dbo].[CAPITALIZE_STRING]
	@inoutString VARCHAR(100) OUTPUT
AS
BEGIN
	-- SET NOCOUNT ON added to prevent extra result sets from
	-- interfering with SELECT statements.
	SET NOCOUNT ON;

	select @inoutString = upper(@inoutString);

END

GO

Creating the Function

USE [sitest]
GO

IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[GET_COOL_NUMBER]') AND type in (N'FN', N'IF', N'TF', N'FS', N'FT'))
DROP FUNCTION [dbo].[GET_COOL_NUMBER]
GO

SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

-- Description:	Simple Function that returns a constant number
-- ===========================================================

CREATE FUNCTION [dbo].[GET_COOL_NUMBER]
(
)
RETURNS int
AS
BEGIN
	DECLARE @cool_number int = 12345;
	RETURN @cool_number;
END

GO

Setting up the DataSource

You may have to update the Microsoft SQL Server properties in:

/src/main/resources/META-INF/spring/integration/spring-integration-context.xml

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
	destroy-method="close">
	<property name="driverClass" value="net.sourceforge.jtds.jdbc.Driver" />
	<property name="jdbcUrl" value="jdbc:jtds:sqlserver://172.16.48.128:1433/sitest" />
	<property name="user" value="sitest" />
	<property name="password" value="integration" />
</bean>

Run the Sample

• running the "Main" class from within STS (Right-click on Main class --> Run As --> Java Application)

• or from the command line:

  $ gradlew :stored-procedures-ms:run
