NAME

DBIx::SQLEngine::Driver::Sybase::MSSQL - Support Microsoft SQL via DBD::Sybase

SYNOPSIS

DBI Wrapper: Adds methods to a DBI database handle.

  my $sqldb = DBIx::SQLEngine->new( 'dbi:Sybase:server=MyServer' );

Portability Subclasses: Uses driver's idioms or emulation.

  $sqldb->select_dbms_flavor('MSSQL');

  $hash_ary = $sqldb->fetch_select( 
    table => 'students' 
    limit => 5, offset => 10
  );

DESCRIPTION

This package provides a subclass of DBIx::SQLEngine::Driver::Sybase which compensates for configurations in which DBD::Sybase is being used to communicate with a Microsoft SQL Server database.

If you are connecting to a Microsoft SQL Server through ODBC, you should use the regular MSSQL driver; see DBIx::SQLEngine::Driver::MSSQL

For more information, see "Using DBD::Sybase with MS-SQL" in DBD::Sybase.

Under Development

Note that this driver class has been added recently and not yet tested in real-world conditions.

About DBMS Flavors

This subclass of the Sybase driver must be specifically triggered, because the package is unable to automatically detect the difference between using DBD::Sybase with a Sybase server and using it with a Microsoft server.

To do this, call select_dbms_flavor after connecting:

  my $sqldb = DBIx::SQLEngine->new( 'dbi:Sybase:server=MyServer' );
  
  $sqldb->select_dbms_flavor('MSSQL');

For more information, see the documentation for the superclass, DBIx::SQLEngine::Driver::Sybase.

INTERNAL STATEMENT METHODS (DBI STH)

No Placeholders

When using DBD::Sybase to talk to a Microsoft SQL Server, "?"-style placeholders are not supported.

Uses the NoPlaceholders trait. For more information, see DBIx::SQLEngine::Driver::Trait::NoPlaceholders.

INTERNAL STATEMENT METHODS (DBI STH)

Statement Handle Lifecycle

prepare_execute()

After the normal prepare_execute cycle, this also sets the sth's LongReadLen to dbms_longreadlen_bufsize().

dbms_longreadlen_bufsize()

Set to 1_000_000.
