sp_setdefaultdatatypemapping (Transact-SQL)

Marks an existing data type mapping between Microsoft SQL Server and a non-SQL Server database management system (DBMS) as the default. This stored procedure is executed at the Distributor on any database.

Arguments

• [ @mapping_id= ] mapping_id
  Identifies an existing data type mapping. mapping_id is int, with default value of NULL. If you specify mapping_id, then the remaining parameters are not required.

• [ @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.

  Value	Description
  MSSQLSERVER	The source is a SQL Server database.
  ORACLE	The source is an Oracle database.
  NULL (default)

  You must specify this parameter if mapping_id is 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. You must specify this parameter if mapping_id is 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 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.

  Value	Description
  MSSQLSERVER	The destination is a SQL Server database.
  ORACLE	The destination is an Oracle database.
  DB2	The destination is an IBM DB2 database.
  SYBASE	The destination is a Sybase database.
  NULL (default)

• [ @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'
  Is the data type listed in the destination DBMS. destination_type is sysname, with a default value of NULL.

• [ @destination_length= ] destination_length
  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
  Is the precision of the data type in the destination DBMS. destination_precision is bigint, with a default value of NULL.

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

• [ @destination_nullable= ] destination_nullable
  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 means that NULL values are supported.

Return Code Values

0 (success) or 1 (failure)

Remarks

sp_setdefaultdatatypemapping is used in all types of replication between SQL Server and a non-SQL Server DBMS.

The default data type mappings apply to all replication topologies that include the specified DBMS.

Permissions

Only members of the sysadmin fixed server role can execute sp_setdefaultdatatypemapping.
