IBProvider 3.13.3. First new year release and free access to LCPI ADO.NET Data Provider for OLEDB

Firebird driver

A half year before we product first release of LCPI ADO.NET Data Provider for OLEDB, which became powerful alternative of standard .Net OLE DB Provider and provide advanced opportunities for all Firebird and Interbase users in .Net Framework:

  • Automatic generation of command parameters which you do not need to enter manually anymore;
  • Named and unnamed parameters, also IN, OUT and IN-OUT parameters;
  • Connection pooling and SQL statement pooling which let your code run even faster;
  • Nested (┬źnested_trans=true┬╗) and distributed (TransactionScope, EnlistTransaction) transactions;
  • All data types, including GUID, TIME (Dialect 3), DATE (Dialect 3) and multidimensional arrays;
  • The MARS technology which enables working simultaneously with several active DataReader objects;
  • And hey, ExecuteScalar now really loads one value only, not the entire record
  • Multiple parameter-containing commands in one statement (SQL scripts);

Up to this day LCPI ADO.NET Data Provider for OLEDB was available only in professional version of IBProvider but now you can download it on the download page together with first release of IBProvider in the new year:

Dozens of new options for Firebird and .NET Framework

Hey!

If you have ever worked with Firebird or Interbase using the standard .NET provider for OLE DB (System.Data.OleDb), you will have likely encountered issues like this:

  • The necessity to add ALL parameters manually.
  • Even though the OLE DB provider supports parameter generation for commands, the .NET provider doesn’t use it, so you as the programmer must do that work on your own.
  • The lack of support for named parameters. Although they actually exist, using them in reality requires a whole set of complex manipulations (the steps needed to add a parameter to a collection, etc.).
  • The impossibility of using multiple DataReader objects at the same time (Multiple Active Result Sets).
  • No execution of SQL scripts which contain several SQL expressions per command. This list of difficulties a .NET developer has to deal with is far from complete. Now it’s all different in a fundamentally new .NET Data Provider for OLE DB

Are your data access components ready for Firebird 3?


Firebird 3 driver for OLE DB

We are continuing to actively add new functionality of Firebird 3 DBMS to IBProvider.

Let us remind you that already 2 months ago we added support of BOOLEAN data type from Firebird 3. In the new version of IBProvider Professional, we added support of PACKAGE instruction.

Now you can put in order a bulk of database procedures and functions and group them by sense into individual modules (PACKAGE). This arrangement will substantially simplify understanding and maintenance of SQL code.

Know how to add execution of SQL-scripts in your programs!

online poker news

Do you want to enable execution of SQL scripts in your programs and spend less time for exhausting coding?

Do you want to create a table, a generator and a trigger, to add data to the table, to make data selection and then to delete all this in one command? For example:


set autoddl on;
set transaction;
create generator GEN_ID_TEST_TABLE;
create table TEST_TABLE (ID INTEGER NOT NULL PRIMARY KEY,TEXT BLOB SUB_TYPE TEXT);
create trigger BI_TEST_TABLE for TEST_TABLE
 before insert
 as
 begin
  if(NEW.ID IS NULL) then NEW.ID=GEN_ID(GEN_ID_TEST_TABLE,1);
 end;
insert into TEST_TABLE (text) values('record 1');
insert into TEST_TABLE (text) values('record 2');
set term !!;
select * from TEST_TABLE!!
set terminator ;!!
TEST_TABLE;
set autoddl off;
drop table TEST_TABLE;
drop generator GEN_ID_TEST_TABLE;
commit;

Now it is possible with new IBProvider! IBProvider v.3.3.0.11117 allows to run a command with several SQL queries (SQL scripts).

Do you use TIME and TIMESTAMP in your applications? The new IBProvider version will further simplify your work!

Have you ever lost microseconds when working with the type TIME?
Definitely, if you have ever tried to use them. In the previous versions of IBProvider, time was stored in OLE DB structure of DBTYPE_DBTIME type that does not support fractions of a second.


In the new IBProvider version, time data types have been improved
. The new properties dbtime_rules and dbtimestamp_rules allow to set time storage not only in DBTIME/DBTIMESTAMP but also in WSTR and in the new type of MS SQL 2008 – DBTIME2 without losing milliseconds.

Is it possible to write a similar Firebird database driver?

Today we are (IBProvider team) overwhelmingly happy because we have finally released the final build of the 3rd version of IBProvider.

Is it possible to write a similar database driver?

Of course, you can write it! All you need is a strong desire and 7 years of free time. Exactly the same time it took us to write the third version of IBProvider.
