解説

When this property is set, the 本製品 scans the specified number of rows (objects) in the XML document to detect columns and datatypes. The scans follow nested objects, counting each object array as a single row.

If no schema (RSD) is available for the table, columns are determined dynamically using this scan. The behavior applies when using GenerateSchemaFiles or when a schema file is not present.

Higher values improve detection accuracy but may increase request time. Setting this property to 0 causes the 本製品 to parse the entire XML document.

This property is useful for controlling the trade-off between schema detection accuracy and query performance when parsing XML data.
