Specifies how the provider determines the data types of columns in the generated schema.

Possible Values

Data Type

string

Default Value

"RowScan"

Remarks

When this property is set to None, all columns are returned as string values without data type inference.

When this property is set to RowScan, the server scans a sample of rows to heuristically infer column data types. The number of rows scanned is determined by the RowScanDepth property.

This property is useful for controlling the method of type inference during schema discovery.
