    <p>I looked at the SQLTeam website but now am having a new problem cause I have an IDENTITY column and their example does not. </p> <p>I have SQL Server 2008 and VS 2008. I am trying to execute the InsertPIF SP using C# and a table UDT, but am getting an exception. I have looked at a SQLTeam website example with a Table UDT, but their example doesn't have an identity column like mine does.</p> <p>However, their example table doesn't have an identity column like mine. What I am trying to do should be simple. I have tried many different variations of this, but essentially:</p> <pre><code>ALTER PROCEDURE [dbo].[InsertPIF] @InputFileParam parseInputFile READONLY AS INSERT dbo.ParentTable SELECT strRow FROM @InputFileParam GO </code></pre> <p>where</p> <pre><code>CREATE TABLE [dbo].[ParentTable]( [ParentID] [int] IDENTITY(1,1) NOT NULL, [strInput] [varchar](8000) NULL, PRIMARY KEY NONCLUSTERED (...) </code></pre> <p>and type:</p> <pre><code>CREATE TYPE [dbo].[parseInputFile] AS TABLE( [NumCols] [int] IDENTITY(1,1) NOT NULL, [strRow] [varchar](500) NOT NULL, PRIMARY KEY CLUSTERED (...) </code></pre> <p>What I am trying to do is to execute the above SP to insert new records into the ParentTable. Example:</p> <pre><code>INSERT INTO ParentTable(strInput) VALUES ('A3|BB|C|DDD') INSERT INTO ParentTable(strInput) VALUES ('A4|GOB|BLDY|GOOK') INSERT INTO ParentTable(strInput) VALUES ('A5|Hello|My|Darling') </code></pre> <p>Here is more of my C# code prior to the AppendData section:</p> <pre><code>DataTable dt = new DataTable(); String[] header = myStringArray[0].Split('|'); DataRow dr = dt.NewRow(); DataColumn dc = new DataColumn(); dc.DataType = typeof(Int32); dc.ColumnName = “NumCols”; dc.AutoIncrement=true; dt.Columns.Add(dc); DataColumn dc2 = new DataColumn(); dc2.DataType = typeof(string); dc2.ColumnName = “strRow”; dt.Columns.Add(dc2); dr["NumCols"] = 1; dr["strRow"] = "AA|BBB|CC|DD|E"; dt.Rows.Add(dr); ... SqlConnection conn = new SqlConnection(connString); SqlCommand cmd = conn.CreateCommand(); cmd.CommandText = "dbo.InsertPIF"; cmd.CommandType = CommandType.StoredProcedure; cmd.Connection = conn; SqlParameter param = cmd.Parameters.AddWithValue("@InputFileParam", SqlDbType.Structured); param.Value = dt; conn.Open(); RowsAffected = cmd.ExecuteNonQuery(); </code></pre> <p>I set identity to be turned on for the <code>ParentTable</code>, but it seems like I have to execute this each session, so I'm not sure how to remove identity requirement or else to make identity remain on. Exception:</p> <p>INSERT into an identity column not allowed on table variables. The data for table-valued parameter '@InputFileParam' doesn't conform to the table type of the parameter.</p> <p>How do I execute this SP?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
