ExecuteArray and nullable int32 or nullable decimal values

ExecuteArray and nullable int32 or nullable decimal values

Postby HCRoman » Fri 24 Jun 2011 10:03

Hi devart team,

i have trouble with nullable int32 and nullable decimal parameters during ExecuteArray calls.

(I have not checked all other datatypes yet...)

The parameter has correct settings
param.IsNullable = true
and the values in the array also nullable types

I get an exception
InvalidCastException

Any help or bugfix??

I am using the last release build version:

6.30.160.0

Could you please tell us how we should modify this code to reproduce the error?
Code: Select all
//CREATE TABLE TEST (
//  ID NUMBER(38),
//  COL1 NUMBER(38),
//  COL2 NUMBER(38,9),
//  CONSTRAINT PK_TEST PRIMARY KEY (ID));

    using (OracleConnection conn = new OracleConnection(connStr)) {
        conn.Open();
        OracleCommand cmd = conn.CreateCommand();
        cmd.CommandText = "insert into test values (:id, :col1, :col2)";
        cmd.Parameters.Add("id", OracleDbType.Integer).Value = new Int32[] { 1 };
        cmd.Parameters.Add("col1", OracleDbType.Integer).Value = new Int32?[] { null };
        cmd.Parameters.Add("col2", OracleDbType.Number).Value = new Decimal?[] { null };
        cmd.ExecuteArray(1);
    }

Hi Shalex,

Yes,

append any not null value in your nullable datatype array!

Code: Select all
//CREATE TABLE TEST (
//  ID NUMBER(10),
//  COL1 NUMBER(5),
//  COL2 NUMBER(13,2),
//  CONSTRAINT PK_TEST PRIMARY KEY (ID));

    using (OracleConnection conn = new OracleConnection(connStr)) {
        conn.Open();
        OracleCommand cmd = conn.CreateCommand();
        cmd.CommandText = "insert into test values (:id, :col1, :col2)";
        cmd.Parameters.Add("id", OracleDbType.Integer).Value = new Int32[] { 1, 2 };
        cmd.Parameters.Add("col1", OracleDbType.Integer).Value = new Int32?[] { null, 55555};
        cmd.Parameters.Add("col2", OracleDbType.Number).Value = new Decimal?[] { null, 1.22m};
        cmd.ExecuteArray(2);
    }

The bug with OracleCommand.ExecuteArray() for nullable value types is fixed. We will post here when the corresponding build is available for download.
