DBIx::Class::Storage::UserxContributedoPegl:DDcumentatiMicrosoft_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.

FURTHER	QUESTIONS?
       Check the list of additional DBIC resources.
