Description
Influences what is included in data packets and how the information in data packets is used.
Set Options to customize how the provider communicates with client datasets. Options is a set that specifies:
- Whether nested detail sets and BLOB data are included in data packets or fetched separately.
- Whether data packets include field component properties such as formats, display names, and maximum & minimum values.
- Whether data packets are provided on a read-only basis, and whether specific types of changes (insertions, edits, or deletions) are disabled.
- Whether changes to master table fields should cause corresponding updates to detail tables.
- Whether a single update can affect multiple server records.
- Whether the client's records are refreshed when it applies updates.
- Whether the client can send SQL statements that override the provider's dataset.
Note: Not all options are supported by an InternetExpress client. Specifically, InternetExpress clients don't support poFetchBlobsOnDemand, poFetchDetailsOnDemand, poDisableInserts, poDisableEdits, psDisableDeletes, poPropogateChanges, and poAllowCommandText.
