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=EEEBOXSQLEXPRESS

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.

NAME

       DBIx::Class::Storage::DBI::ADO::MS_Jet - Support for MS Access over ADO

DESCRIPTION

       This driver is a subclass of DBIx::Class::Storage::DBI::ADO and DBIx::Class::Storage::DBI::ACCESS for connecting to MS Access via DBD::ADO.

       See the documentation for DBIx::Class::Storage::DBI::ACCESS for information on the MS Access driver for DBIx::Class.

       This driver implements workarounds for "TEXT/IMAGE/MEMO" columns, sets the cursor_class to DBIx::Class::Storage::DBI::ADO::MS_Jet::Cursor
       to normalize returned "GUID" values and provides DBIx::Class::InflateColumn::DateTime support for "DATETIME" columns.

EXAMPLE DSNs
	 # older Access versions:
	 dbi:ADO:Microsoft.Jet.OLEDB.4.0;Data Source=C:Users
kitoverDocumentsaccess_sample.accdb

	 # newer Access versions:
	 dbi:ADO:Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:Users
kitoverDocumentsaccess_sample.accdb;Persist Security Info=False'

TEXT
/IMAGE/MEMO COLUMNS
       The ADO driver does not suffer from the problems the ODBC driver has with these types of columns. You can use them safely.

       When you execute a "CREATE TABLE" statement over this driver with a "TEXT" column, it will be converted to "MEMO", while in the ODBC driver
       it is converted to "VARCHAR(255)".

       However, the caveat about LongReadLen having to be twice the max size of your largest "MEMO/TEXT" column +1 still applies. DBD::ADO sets
       LongReadLen to a large value by default, so it should be safe to just leave it unset. If you do pass a LongReadLen in your connect_info, it
       will be multiplied by two and 1 added, just as for the ODBC driver.
