I have a problem with saving 4000 characters to varchar2(4000) oracle 10g column
it lets me save just 2000 characters and when I try to save exceeding 2000 character

I get tihs error

Can’t save: GENERAL_ NOTE exceeds the maximum length of 4000

this is subsonic column definition
TableSchema.TableColumn colvarGeneralNote = new
TableSchema.TableColumn(schema);
colvarGeneralNote.ColumnName = “GENERAL_NOTE”;
colvarGeneralNote.DataType = DbType.String;
colvarGeneralNote.MaxLength = 4000;
colvarGeneralNote.AutoIncrement = false;
colvarGeneralNote.IsNullable = true;
colvarGeneralNote.IsPrimaryKey = false;
colvarGeneralNote.IsForeignKey = false;
colvarGeneralNote.IsReadOnly = false;
colvarGeneralNote.DefaultSetting = @””;
colvarGeneralNote.ForeignKeyTableName = “”;
schema.Columns.Add(colvarGeneralNote);

I can’t save a string with exceeding 2000 characters to my varchar2(4000) column

Please advise me for that issue

Thanks – Adem

    it could mean that you are inserting multi-byte data.
    try changing field definition to : varchar2(4000 char)

    also what is nls_length_semantics in your db and the Characterset.
