Estoy tratando de insertar por lotes datos en SQL 2008 usando SqlBulkCopy
.Error al insertar datos usando SqlBulkCopy
Aquí está mi mesa:
IF OBJECT_ID(N'statement', N'U') IS NOT NULL
DROP TABLE [statement]
GO
CREATE TABLE [statement](
[ID] INT IDENTITY(1, 1) NOT NULL,
[date] DATE NOT NULL DEFAULT GETDATE(),
[amount] DECIMAL(14,2) NOT NULL,
CONSTRAINT [PK_statement] PRIMARY KEY CLUSTERED
(
[ID] ASC
) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
Aquí está mi código:
private DataTable GetTable()
{
var list = new List<DataColumn>();
list.Add(new DataColumn("amount", typeof(SqlDecimal)));
list.Add(new DataColumn("date", typeof(SqlDateTime)));
var table = new DataTable("statement");
table.Columns.AddRange(list.ToArray());
var row = table.NewRow();
row["amount"] = (SqlDecimal)myObj.Amount; // decimal Amount { get; set; }
row["date"] = (SqlDateTime)myObj.Date; // DateTime Date { get; set }
table.Rows.Add(row);
return table;
}
private void WriteData()
{
using (var bulk = new SqlBulkCopy(strConnection, SqlBulkCopyOptions.KeepIdentity & SqlBulkCopyOptions.KeepNulls))
{
//table.Columns.ForEach(c => bulk.ColumnMappings.Add(new SqlBulkCopyColumnMapping(c.ColumnName, c.ColumnName)));
bulk.BatchSize = 25;
bulk.DestinationTableName = "statement";
bulk.WriteToServer(GetTable()); // a table from GetTable()
}
}
así que estoy de error:
The given value of type
SqlDateTime
from the data source cannot be converted to typedate
of the specified target column.
Por qué ?? ¿Cómo puedo arreglar eso? ¡Ayudame por favor!
¿No debería ser eso "SqlBulkCopyOptions.KeepIdentity | SqlBulkCopyOptions.KeepNulls"? – rusty
