DBIx::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.

This code is incomplete and may be buggy. Particularly, "VARCHAR(MAX)" is not supported yet. The data_type list for other DBs is also incomplete. Please report problems (and send patches.)

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