We found out that on some cases we get NET: Unknown Error 1.
Please take a look at this sample:
DDL:
Code: Select all
CREATE TABLE TEST
(
ID NUMBER(19) NOT NULL,
NAME VARCHAR2(1000 CHAR) NOT NULL,
LAST_UPDATED_DT DATE NOT NULL
);
CREATE UNIQUE INDEX AK_TEST_NAME ON TEST
(NAME);
CREATE OR REPLACE TRIGGER BIU_TEST_DT
BEFORE INSERT OR UPDATE
ON TEST REFERENCING NEW AS New OLD AS Old
for each row
begin
:new.last_updated_dt := sys_extract_utc(SYSTIMESTAMP);
end;
INSERT INTO TEST(ID,NAME)
VALUES(1,'TEST DATA');
INSERT INTO TEST(ID,NAME)
VALUES(2,'TEST DATA2');
COMMIT;Code: Select all
private static void Main(string[] args)
{
string connectionString = "User Id=<...>;Password=<...>;Direct=true;Data Source=<...>;Port=1521;SID=<...>;Pooling=true;Unicode=true";
using (var transaction = new TransactionScope(TransactionScopeOption.Required,
new TransactionOptions {IsolationLevel = IsolationLevel.ReadCommitted}))
{
using (OracleConnection connection = new OracleConnection(connectionString))
{
connection.Open();
using (var command = connection.CreateCommand())
{
var array = new decimal?[1];
array.SetValue((decimal?) 2, 0);
var arrayGenericName = new String[1];
arrayGenericName.SetValue("TEST DATA", 0);
var arrayLastUpdatedDate = new DateTime[1];
command.CommandText = "update TEST set name = :name where id = :id RETURNING LAST_UPDATED_DT INTO :LastUpdatedDt";
command.PassParametersByName = true;
var idParam = new OracleParameter("id", OracleDbType.Number)
{
Value = array,
Direction = ParameterDirection.Input
};
var genericNameParam = new OracleParameter("name", OracleDbType.VarChar)
{
Value = arrayGenericName,
Direction = ParameterDirection.Input
};
var lastUpdatedDateParam = new OracleParameter("LastUpdatedDt", OracleDbType.Date)
{
Value = arrayLastUpdatedDate,
Direction = ParameterDirection.Output
};
command.Parameters.Add(genericNameParam);
command.Parameters.Add(idParam);
command.Parameters.Add(lastUpdatedDateParam);
command.ExecuteArray(array.Length);
}
}
transaction.Complete();
}
Meanwhile I'm sending demo project to [email protected]
Thanks!
