How to put large text data (~20mb) into sql cs 3.5 database?
- by Anindya Chatterjee
I am using following query to insert some large text data :
internal static string InsertStorageItem =
"insert into Storage(FolderName, MessageId, MessageDate, StorageData) values ('{0}', '{1}', '{2}', @StorageData)";
and the code I am using to execute this query is as follows :
string content = "very very large data";
string query = string.Format(InsertStorageItem, "Inbox", "AXOGTRR1445/DSDS587444WEE", "4/19/2010 11:11:03 AM");
var command = new SqlCeCommand(query, _sqlConnection);
var paramData = command.Parameters.Add("@StorageData", System.Data.SqlDbType.NText);
paramData.Value = content;
paramData.SourceColumn = "StorageData";
command.ExecuteNonQuery();
But at the last line I am getting this following error :
System.Data.SqlServerCe.SqlCeException was unhandled by user code
Message=The data was truncated while converting from one data type to another. [ Name of function(if known) = ]

Now my question is how am I supposed to insert such large data to sqlce db?
