How to pass a list of parameter to stored procedure and perform batch insert in SQL Server

Question

I'm using Spring JDBCTemplate to connect to the SQL Server.

I have a list of Objects that needed to be inserted into a table of SQL Server.

What I did is the following:

public void batchInsert(final List<Bean> list) {

    final String sql = "insert into temp"
            + "(id, name, amount, location, time, price) "
            + " values (?, ?, ?, ?, ?, ?)";

    getJdbcTemplate().batchUpdate(sql, new BatchPreparedStatementSetter() {

        @Override
        public void setValues(PreparedStatement ps, int i) throws SQLException {
            Bean vo = list.get(i);
            ps.setString(1, vo.getId());
            ps.setString(2, vo.getName());
            ps.setDouble(3, vo.getAmount());
            ps.setString(4, vo.getLocation());
            ps.setString(5, vo.getTime());
            ps.setDouble(6, vo.getPrice());
        }

        @Override
        public int getBatchSize() {
            return list.size();
        }
    });
}

But now, I'd like to pass the parameter List<Bean> list to a stored procedure which handle the batch insert as high efficient as possible.

May I ask how to implement this?

Answer 1

First of all don't write query directly as it can be security breach to Your application. For bulk data storage the way normally get followed is XML Way. Try to implement it through XML.

Answer 2

You can use Table variable parameter for your stored procedure :

CREATE TYPE RecordList AS TABLE (Id Int, Name NVarChar(100), Amount int, location nvarchar(100), ...)

CREATE PROCEDURE test 
    @RecordList dbo.RecordList READONLY
AS Begin
    Insert Into temp (id, name, amount, location , ...)
    Select id, name, amount, location, ...)
    from @RecordList
End

I don't work with Spring JDBCTemplate but you can use following reference in order to use table variable parameter in C#:
