Hello, I have a question.

When I use pgsqlConnection and pgsqlCommand
like following

...
DbConnection conn = new PgSqlConnection(connStr);
DbCommand command= new PgSqlCommand(SPName, conn as PgSqlConnection);

....
and use DbDataReader

using (DbDataReader Odbcdr = command.ExecuteReader())
{
PARAM_VALUE = dr[valueColName] == DBNull.Value ? 0 : Convert.ToDouble(dr[valueColName]),
}

and read like upper code.

but I face a error like this.




Decimal's scale value must be between 0 and 28, inclusive.

I know data is more than 28 size.
I can round, but When reading , It is faced error.
So I want to know How to read and round this data.

I try like following.
But it is same.

double dParmaValue = 0.0;
Double.TryParse(dr[valueColName].ToString(), out dParmaValue);


Please give me advice.

Please try using the latest (7.7.852) version of dotConnect for PostgreSQL. It can be downloaded from http://www.devart.com/dotconnect/postgresql/download.html (trial version) or from Registered Users' Area (for users with valid subscription only).

Is the issue reproduced with the latest version?
