.NET SQL CE Core - Not enough storage is available to complete this operation
I am using SQL CE to store data in my application. I got an error with the below code after executing it for around 3000 times:
"Not enough storage is available to complete this operation"
The error is happened on a LIVE application.
SqlCeConnection开发者_JAVA百科 connection;
SqlCeTransaction transaction;
try
{
connection = new SqlCeConnection(connectionString);
connection.Open();
transaction = connection.BeginTransaction();
SqlCeCommand deleteCmd = connection.CreateCommand();
deleteCmd.CommandText ="Delete from EJData where ID=@id";
deleteCmd.Parameters.Add("@id", SqlDbType.Int, Int32.MaxValue.ToString().Length, "ID");
adapter.DeleteCommand = deleteCmd;
adapter.DeleteCommand.Transaction = transaction;
DataRow[] r = dataSet.Tables[0].Select("ID >=" + firstRecordID + " and ID<=" + lastRecordID);
foreach (DataRow row in r)
{
row.Delete();
}
adapter.Update(dataSet,"EJData" );
transaction.Commit(CommitMode.Immediate);
transaction.Dispose();
transaction = null;
}
catch ( ... )
{
...
}
finally
{
if (adapter.DeleteCommand != null)
{
adapter.DeleteCommand.Dispose();
}
connection.Close();
}
when declaring the parameter use this: deleteCmd.Parameters.Add("@id", SqlDbType.Int, "ID");
