Supported data types

The following table shows the supported Microsoft SQL Server source data types and their default mapping to Replicate data types.

When replicating to a Microsoft SQL Server-based target, the source and target data types are the same, apart from the exceptions described in Homogeneous replication.

For information on how to view the data type that is mapped in the target, see the section for the target endpoint you are using.

For additional information about Replicate data types, see Replicate data types.

Information note

When row size exceeds 8060, the VARCHAR, NVARCHAR, and VARBINARY data types will be stored out-of-row. To replicate such data, use the source lookup function described in Data Enrichment.

Information note

Collatable data types are indicated by an asterisk (*).
