CreateParameter Method (PgSqlCommand)
Creates a new instance of a
PgSqlParameter object.
This sample shows how to create a parameter using
CreateParameter function.
Public void CreateParam(PgSqlConnection pgConnection)
{
PgSqlCommand pgCommand = new PgSqlCommand("SELECT * FROM Test.Dept WHERE DeptNo=:Deptno",pgConnection);
PgSqlParameter myParam = pgCommand.CreateParameter();
myParam.PgSqlType = Devart.Data.PostgreSql.PgSqlType.Int;
myParam.Value = 10;
myParam.ParameterName = "Deptno";
pgCommand.Parameters.Add(myParam);
pgConnection.Open();
PgSqlDataReader pgReader = null;
try
{
pgReader = pgCommand.ExecuteReader();
while (pgReader.Read())
{
Console.WriteLine(pgReader.GetInt32(0) + ", " + pgReader.GetString(1) + ", " + pgReader.GetString(2));
}
}
finally
{
pgReader.Close();
pgConnection.Close();
}
}
Public Sub CreateParam(ByVal pgConnection As PgSqlConnection)
Dim pgCommand As New PgSqlCommand("SELECT * FROM Test.Dept WHERE DeptNo=:Deptno", pgConnection)
Dim myParam As PgSqlParameter = pgCommand.CreateParameter()
myParam.PgSqlType = Devart.Data.PostgreSql.PgSqlType.Int
myParam.Value = 10
myParam.ParameterName = "Deptno"
pgCommand.Parameters.Add(myParam)
pgConnection.Open()
Dim pgReader As PgSqlDataReader = Nothing
Try
pgReader = pgCommand.ExecuteReader()
While pgReader.Read()
Console.WriteLine(pgReader.GetInt32(0).ToString() + ", " _
+ pgReader.GetString(1) + ", " _
+ pgReader.GetString(2))
End While
Finally
pgReader.Close()
pgConnection.Close()
End Try
End Sub
