DBIx::Class::Storage::UDBIx::Class::Storage::DBI::ADO::Microsoft_SQL_Server(3)

NAME
       DBIx::Class::Storage::DBI::ADO::Microsoft_SQL_Server - Support for
       Microsoft SQL Server via DBD::ADO

SYNOPSIS
       This subclass supports MSSQL server connections via DBD::ADO.

DESCRIPTION
       The MSSQL specific functionality is provided by
       DBIx::Class::Storage::DBI::MSSQL.

EXAMPLE DSN
	 dbi:ADO:provider=sqlncli10;server=EEEBOX\SQLEXPRESS

CAVEATS
   identities
       "_identity_method" is set to @@identity, as "SCOPE_IDENTITY()" doesn't
       work with DBD::ADO. See "IMPLEMENTATION NOTES" in
       DBIx::Class::Storage::DBI::MSSQL for caveats regarding this.

   truncation bug
       There is a bug with MSSQL ADO providers where data gets truncated based
       on the size of the bind sizes in the first prepare call:

       <https://rt.cpan.org/Ticket/Display.html?id=52048>

       The "ado_size" workaround is used (see "ADO Providers" in DBD::ADO)
       with the approximate maximum size of the data_type of the bound column,
       or 8000 (maximum VARCHAR size) if the data_type is not available.

       Please report problems with this driver and send patches.

   LongReadLen
       "LongReadLen" is set to "LongReadLen * 2 + 1" on connection as it is
       necessary for some LOB types. Be aware of this if you localize this
       value on the $dbh directly.

   binary data
       Due perhaps to the ado_size workaround we use, and/or other reasons,
       binary data such as "varbinary" column data comes back padded with
       trailing "NULL" chars.  The Cursor class for this driver
       (DBIx::Class::Storage::DBI::ADO::Microsoft_SQL_Server::Cursor) removes
       them, of course if your binary data is actually "NULL" padded that may
       be an issue to keep in mind when using this driver.

   uniqueidentifier columns
       uniqueidentifier columns come back from ADO wrapped in braces and must
       be submitted to the MSSQL ADO driver wrapped in braces. We take care of
       this transparently in this driver and the associated Cursor class
       (DBIx::Class::Storage::DBI::ADO::Microsoft_SQL_Server::Cursor) so that
       you don't have to use braces in most cases (except in literal SQL, in
       those cases you will have to add the braces yourself.)

   fractional seconds
       Fractional seconds with DBIx::Class::InflateColumn::DateTime are not
       currently supported, datetimes are truncated at the second.
