将DataTable存储到SQL Server列

Question

I'm trying to store a DataTable into a single column in a SQL Server table. The idea behind this is a user runs a SQL command and the returned output is stored into a datatable, then I want that datatable to be stored into a SQL Server logging table. Later on I want to be able to retrieve that entire datatable back for displaying on a logging aspx page.

Currently I'm just storing it as a big string but that doesn't give me column headers and the formatting is kinda funky as well as being inefficient.

TIA

Another Idea is to create two tables in your database. It is slightly complex.

One Table contains two columns, Let name the table PTable.

Columns:

ID and ColumnID ID is the primary key and ColumnID contains the name of your column in datatable

After creating this table create another table. It will consists of three fields. Let name it STable. This table stores the columns of you datatable.

Columns:

stblID, PtblID and PtColumnID StbID is the primary key in this table, PtblID is the Primary key of PTable and PtColumnID is the ColumnID of PTable. This table stores the rows of table. Now store the data in this table and receive the data when you need it.

and the simplest idea is to create a table in your datbabase having an xml column and store your datatable as an xml.
