SQL Server Data Type Conversions
This section covers data type conversions between the Cloud Portal and SQL Server databases.
注意
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.
