Supported data types

The following table shows the source data types that are supported when using Qlik Replicate and the default mapping to Qlik Replicate data types. Note that source data types are only mapped to Qlik Replicate data types when the target endpoint is not Microsoft SQL Server-based. For information on data type mapping and collation support when the target endpoint is Microsoft SQL Server-based, see 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 Qlik Replicate data types, see Replicate data types.

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

Non-supported data types

Tables that include columns with the following data types are not supported by Qlik Replicate.

CURSOR

User-defined data types are supported according to their base-type. For example, a user-defined data type based on DATETIME is handled as a DATETIME data type.
