Snowflake Data Type Conversions
This section covers data type conversions between the Cloud Portal and Snowflake databases.
Anmerkung
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.

Notes on Date publishing:
Anmerkung
Alteryx Date columns can be published to existing Snowflake columns of Date, Datetime, and String type.
When Dates are published to Snowflake, the following date formats are supported. In some cases, missing data is inserted into the output value.
Alteryx date format | Snowflake date format |
|---|---|
yy-dd-mm | yy-dd-mm |
yy-mm-dd | yy-mm-dd |
dd-mm-yy | dd-mm-yy |
mm-dd-yy | mm-dd-yy |
mm-yy | mm-yy |
dd-mm | 1970-dd-mm |
mm-dd | 1970-mm-dd |
mm-yy | mm-yy-01 |
On publication, all dates are written in the following format:
yyyy-mm-dd.No other date formats are supported for writing to Snowflake as date values.
