StringVARCHAR 
IntegerBIGINT

NOTE: The Trifacta platform may infer Integer columns containing very large or very small values as String data type. Before you publish, you should verify that your columns containing extreme values are interpreted as Integer type.You can import a target schema to assist in lining up your columns with the expected target. For more information, see Overview of Target Matching.

FloatFLOAT 
BoolBIT 
DatetimeDATETIME2If a time-only value is published as an append to a pre-defined DATETIME2 column, then the output column is prepended with 1900-01-01.
Datetime (with time value only)TIMEIf a value is published as an append to a pre-defined TIME column, then any date information is dropped from the output.
DatetimeVARCHAR

If a Datetime value is published as an append to a pre-defined VARCHAR column, then the output column contains the string value of whatever appears in the Transformer page.

When you publish results from a job through the Export Results window to SQL DW, all Datetime column values are written as String type.
