Argumenty

• [ @mapping_id= ] mapping_id
  Identifies an existing data type mapping.mapping_id is int, with default value of NULL.Jeśli określisz mapping_id, a następnie pozostałe parametry nie są wymagane.

• [ @ 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	Opis
  MSSQLSERVER	Źródło jest SQL Server bazy danych.
  ORACLE	Źródło jest baza danych Oracle.
  NULL(default)

  Ten parametr należy określić, jeśli mapping_id ma wartość NULL.

• [ @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.Ten parametr należy określić, jeśli mapping_id ma wartość NULL.

• [ @source_length_min= ] source_length_min
  Is the minimum length of the data type in the source DBMS.source_length_min is bigint, with a default value of NULL.

• [ @source_length_max= ] source_length_max
  Is the maximum length of the data type in the source DBMS.source_length_max is bigint, with a default value of NULL.

• [ @source_precision_min= ] source_precision_min
  Is the minimum precision of the data type in the source DBMS.source_precision_min is bigint, with a default value of NULL.

• [ @source_precision_max= ] source_precision_max
  Is the maximum precision of the data type in the source DBMS.source_precision_max is bigint, with a default value of NULL.

• [ @source_scale_min= ] source_scale_min
  Is the minimum scale of the data type in the source DBMS.source_scale_min is int, with a default value of NULL.

• [ @source_scale_max= ] source_scale_max
  Is the maximum scale of the data type in the source DBMS.source_scale_max 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 NULL.1 oznacza, że wartości NULL są obsługiwane.

• [ @ destination_dbms =] 'destination_dbms"
  Is the name of the destination DBMS.destination_dbms is sysname, and can be one of the following values.
