MySQL Data Type Conversions
This section covers data type conversions between the Cloud Portal and MySQL databases.
注記
The Alteryx data types listed in this page reflect the raw data type of the converted column. Depending on the contents of the column, the Transformer Page may re-infer a different data type, when a dataset using this type of source is loaded.
Access/Read

Write/Publish
注記
MySQL enforces a limit of 65,535 bytes per row. During publishing, row sizes that are larger than this limit yield a Row size too large error, and the job fails.

注記
If you are appending to an existing table where a column's Alteryx data type is not mapped to the column data type in the target table, a validation error is thrown, as the platform writes unmapped types as String data type.
