how to use table type in .net
1. Create Table type in Sqlserver2008.
CREATE TYPE dbo.WordTable as table( [WordText] [nchar](100) NULL, [WordCount] [int] NULL)
And the target table is:
CREATE TABLE [dbo].[A_WordCount]( [id] [int] IDENTITY(1,1) NOT NULL, [WordText] [nchar](100) NULL, [WordCount] [int] NULL)
2.Create Store Procedure.
ALter PROCEDURE [dbo].[A_Words] @Word as dbo.WordTable READONLYASBEGIN insert into dbo.A_WordCount(WordCount,WordText) select w.WordCount,w.WordText from @Word w END
3. First we will create a table. Then we will pass this table to the store procedure.
public static DataTable ConvertToTable(List<WordClass> wordLst) { DataTable dt = new DataTable(); dt.Columns.Add("WordText", typeof (string)); dt.Columns.Add("Count", typeof (int)); foreach (var word in wordLst) { DataRow row = dt.NewRow(); row["WordText"] = word.WordValue; row["Count"] = word.Count; dt.Rows.Add(row); } return dt; }
public static void WriteData(DataTable dtTable) { commandText = "dbo.[A_Words]"; SqlConnection con; try { using (con = new SqlConnection(connectionString)) { SqlCommand cmd = new SqlCommand(commandText, con); cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.Add(new SqlParameter("@Word", SqlDbType.Structured)); cmd.Parameters["@Word"].Value =http://www.mamicode.com/ dtTable; con.Open(); cmd.ExecuteNonQuery(); con.Close(); } } catch (Exception) { throw; } }
