Specifies the number of rows the provider scans to determine data types for custom field columns.

Data Type

string

Default Value

"100"

Remarks

This property controls how many rows the driver examines when detecting data types for columns created by custom fields.

Increasing the value can improve accuracy in determining data types but may decrease performance, especially for large tables. Decreasing the value can improve performance, but may cause some data types to be inferred incorrectly.

This property is useful when working with tables that contain many custom fields or when data type detection requires higher accuracy.
