Specifies the number of columns that the provider detects when dynamically determining table columns.

Data Type

string

Default Value

"10"

Remarks

This property applies when TypeDetectionScheme is set to ColumnCount.

The connector uses this value to determine how many columns to generate when a schema definition file is not available, such as when using GenerateSchemaFiles.

This property is useful for controlling schema inference when the number of columns is known in advance but no schema definition exists.
