Unsupported Database Columns in Synced Record Types

Overview

This page provides information about the SQL data types that cannot be used when creating synced record types. If your source table contains a column type that is listed in the section for your database, that column cannot be mapped in your record type.

Unsupported data types

The various databases you can use with Appian have unique data types that may not be supported for synced record types. In general, Appian does not support binary, large object (LOB), spatial, or XML types, as well as any user-defined types. The following lists are provided as a reference and may not be comprehensive. Vendor-specific and user-defined types are generally not supported and may cause record types to not sync or other issues.

For binary types, you may still be able to manually map a field in your record type to that column, but it is not guaranteed to work correctly and may fail completely with a future version of Appian.

See the individual software sections for information about the specific types not supported by Appian.

If your table includes LONG or BIGINT columns, the safe range of values is from -2,147,483,647 to 2,147,483,647. Numbers outside that range may not be synced correctly. See the Number (Integer) data type for more information about number values in Appian.
