Older ODBC Release Notes

## 1 Older ODBC Release Notes

### 1.1 odbc 1.0.6

#### 1.1.1 Improvements and New Features

- Error handling has been enhanced and better documented
  Own Id: OTP-4661

### 1.2 odbc 1.0.5

#### 1.2.1 Fixed Bugs and Malfunctions

- Some error messages originating from the sql-driver where corrupted so that odbc only returned the end of the error message. This has now been fixed.
  Own Id: OTP-4636 Aux Id: seq7766

#### 1.2.2 Improvements and New Features

- The erlang odbc process will now die normally if a connection can not be established. No connection no process it is expected. And as the client has already received the error message that would be the reason with which the erlang process would be stopped, the supervisor report will be superfluous. Naturally you may still get supervisor reports if the erlang process is stopped for any other reason than the above.

### 1.3 odbc 1.0.4

#### 1.3.1 Fixed Bugs and Malfunctions

- API function commit/3 is now exported.
  Own Id: OTP-4593 Aux Id: seq7766
- If an ODBC API function times out it will cause the client to exit with reason timeout. If this exit was caught and the client continued using the connection, the next request could get the answer meant for the previously timed out request, this is no longer the case.

#### 1.3.2 Improvements and New Features

- Improved error messages so that the implementation not shall shine through.
  Added possibility to let a connection return rows as tuples instead of lists.
  Own Id: OTP-4605 Aux Id: seq7766
- Scrollable cursors are nice but causes some overhead. For some connections speed might be more important than flexible data access and then you can disable scrollable cursor for a connection, limiting the API but gaining speed.

#### 1.4.2 Improvements and New Features

- The Erlang ODBC application consists of both Erlang and C code. The C code is delivered as a precompiled executable for windows and solaris. For the purpose of recompilation or compiling on some other platform there is a Makefile included.
  Own Id: OTP-4193 Aux Id: seq7190
- Expensive constructs such as lists:flatten/1, double buffering and string compare has been replaced by more efficient constructs or when possible totally eliminated.
  Own Id: OTP-4362
- New API that has an Erlang/OTP touch and feel instead of being a C-interface with Erlang syntax. The old interface is deprecated and will be removed in release R10.
  *** POTENTIAL INCOMPATIBILITY ***
  Own Id: OTP-4498
- API functions that became deprecated in version 0.9.1 has been removed.
