Description

TAutoIncFieldsMode is an auto incremental fields detection mode that optimizes dataset time.

Some OLEDB providers, like SQL Server one, exchange additional data packets with a DB server to detect if a field is an auto-incrementing one. On a large SELECT list, this may affect performance critically.

TAutoIncFieldsMode items are

• afAll - try to detect if any field is an auto-increment field or not.
• afFirst - stop the detection of auto-increment fields after the first one is found.
• afNone - do not detect auto-increment fields.
