在JDBC中传递table参数给SQL server stored procedure

SQL Server JDBC驱动不支持直接传递Table参数给stored procedure
我的做法是先创建一个临时表，将需要插入的数据先插入到临时表里面，然后把这个临时表作为参数，传送给stored procedure。使用了Preparestatement来避免SQL注入问题。
先创建User Defined Table

CREATE TYPE UserIdList AS TABLE(
	userId uniqueidentifier NOT NULL
);

再创建存储过程：

CREATE PROC insertIntoExamArrange
	@subjectId uniqueidentifier,
	@startTime datetime2(0),
	@duration time(7),
	@site nvarchar(255),
	@examName nvarchar(255),
	@studentIdList dbo.UserIdList READONLY,
	@supervisorIdList dbo.UserIdList READONLY
AS
BEGIN
DECLARE @op TABLE (
			colGuid uniqueidentifier
		);
DECLARE @examId uniqueidentifier;
	BEGIN TRAN
		INSERT INTO dbo.ExamArrange
			(subjectId,startTime,duration,site,examName)
		OUTPUT inserted.examId
		INTO @op
		VALUES(@subjectId, @startTime, @duration, @site, @examName);
		
		SELECT TOP 1 
			@examId = colGuid
		FROM @op;
		
		INSERT INTO dbo.Exam_Student_Relationship
			(examId,studentId)
		SELECT @examId, userId
		FROM @studentIdList;
		
		INSERT INTO dbo.Exam_Supervisor_Relationship
			(examId,supervisorId)
		SELECT @examId, userId
		FROM @supervisorIdList;
	COMMIT
END

根据下面的SQL语句，生成相应的Java代码

DECLARE @studentList UserIdList;
INSERT INTO @studentList 
	VALUES('38C6D0B1-948D-412F-80BA-5BADDD7ABF53'),
	('A3E7AAFF-3C0A-4B27-B92E-15DC5FA479BA');
DECLARE @supervisorList UserIdList;
INSERT INTO @supervisorList
VALUES
	('DE6E2A5B-05D9-484A-B225-C8C7265A816B'),
	('2EEBE00E-117D-4382-9828-93C7F6922F75');
	
EXEC dbo.insertIntoExamArrange 
	'D5C544C2-9983-4805-8599-44DDE095289D','2015-12-18 18:16:30','1:50:33',
	'测试楼','编译原理临时考试',@studentList,@supervisorList;

下面是对应上面SQL语句的java代码

public void insertExamArrange(ExamArrange arr, List<User> supervisors,
		List<User> students) throws SQLException {
	StringBuilder query = new StringBuilder();
	if (students.size() > 0) {
		query.append(" DECLARE @studentList UserIdList; "
				+ " INSERT INTO @studentList VALUES(?) ");
		for (int i = 0; i < students.size() - 1; ++i) {
			query.append(" ,(?) ");
		}
		query.append(" ; ");
	}else{ 
		assert students.size()==0;
		query.append(" DECLARE @studentList UserIdList; ");
	}
	if (supervisors.size() > 0) {
		query.append(" DECLARE @supervisorList UserIdList; "
				+ " INSERT INTO @supervisorList  VALUES(?) ");
		for (int i = 0; i < supervisors.size() - 1; ++i) {
			query.append(" ,(?) ");
		}
		query.append(" ; ");
	}else{
		assert supervisors.size()==0;
		query.append(" DECLARE @supervisorList UserIdList; ");
	}
	query.append(" EXEC dbo.insertIntoExamArrange "+
		" ?,?,?,?,?,@studentList,@supervisorList; ");
	
	try(PreparedStatement pre = getConnection().prepareStatement(query.toString())){
		int preIndex = 1;
		
		for(int i=0;i<students.size();++i){
			pre.setString(preIndex, students.get(i).getUserId());
			++preIndex;
		}
		
		for(int i=0;i<supervisors.size();++i){
			pre.setString(preIndex, supervisors.get(i).getUserId());
			++preIndex;
		}
		
		pre.setString(preIndex,arr.getSubjectId());
		++preIndex;
		
		pre.setTimestamp(preIndex, arr.getStartTime());
		++preIndex;
		
		pre.setTime(preIndex, arr.getDuration());
		++preIndex;
		
		pre.setString(preIndex, arr.getSite());
		++preIndex;
		
		pre.setString(preIndex, arr.getExamName());
		++preIndex;
		
		pre.execute();
	}
}
