Argumenty
[ @ source_dbms= ] "source_dbms'
Is the name of the DBMS from which the data types are mapped.source_dbms is sysname, and can be one of the following values:Wartość
Description
MSSQLSERVER
urządzenie źródłowe jest SQL Server Baza danych.
ORACLE
urządzenie źródłowe jest baza danych Oracle.
Należy określić ten parametr.
[ @source_version= ] 'source_version'
Is the version number of the source DBMS.source_version is varchar(10), with a default value of NULL.[ @ source_type= ] "source_type'
Is the data type in the source DBMS.source_type is sysname, with no default.[ @source_length= ] source_length
Is the length of the data type in the source DBMS.source_length is bigint, with a default value of NULL.[ @source_precision= ] source_precision
Is the precision of the data type in the source DBMS.source_precision is bigint, with a default value of NULL.[ @source_scale= ] source_scale
Is the scale of the data type in the source DBMS.source_scale is int, with a default value of NULL.[ @source_nullable= ] source_nullable
Is if the data type in the source DBMS supports a value of NULL.source_nullable is bit, with a default value of 1, which means that NULL values are supported.[ @ destination_dbms = ] "destination_dbms'
Is the name of the destination DBMS.destination_dbms is sysname, and can be one of the following values:Wartość

[ @ destination_version= ] "destination_version'
Is the product version of the destination DBMS.destination_version is varchar(10), with a default value of NULL.[ @ destination_type= ] "destination_type" wyjście
Is the data type listed in the destination DBMS.destination_type is sysname, with a default value of NULL.[ @destination_length= ] destination_length OUTPUT
Is the length of the data type in the destination DBMS.destination_length is bigint, with a default value of NULL.[ @destination_precision= ] destination_precision OUTPUT
Is the precision of the data type in the destination DBMS.destination_precision is bigint, with a default value of NULL.[ @destination_scale= ] destination_scaleOUTPUT
Is the scale of the data type in the destination DBMS.destination_scale is int, with a default value of NULL.[ @destination_nullable= ] destination_nullableOUTPUT
Is if the data type in the destination DBMS supports a value of NULL.destination_nullable is bit, with a default value of NULL.1 oznacza, że wartości NULL są obsługiwane.[ @dataloss= ] datalossOUTPUT
Is if the mapping has the potential for data loss.dataloss is bit, with a default value of NULL.1 oznacza, że istnieje ryzyko utraty danych.

Remarks
sp_getdefaultdatatypemapping jest używany we wszystkich typach replikacja między SQL Server i różna-SQL Server DBMS.
sp_getdefaultdatatypemapping zwraca domyślny typ danych docelowego, który najlepiej pasuje do typu określonego urządzenie źródłowe danych.
Uprawnienia
Tylko członkowie sysadmin stała rola serwera mogą być wykonać sp_getdefaultdatatypemapping.
