ZQuery.Post without field xyz

Post by nlanger »

If I fetch an SQL command from a view and it contains a field that cannot be changed (from another table), it works fine for ZQuery.Edit and ZQuery.Post. An error occurs (from MS-SQLserver) with ZQuery.Insert and ZQuery.Post because the field must not be modified with.

Can I remove the field from the set of fields to be changed?

In Zeos 6.6.6 it worked with: TZDataset(QU_).SetFieldDesc(F,True);

Hello Norbert,

this sounds like a bug if Zeos ignores the field for updates but doesn't ignore it for inserts. Is the field correctly marked as ReadOnly? I added some preliminary release notes. Maybe the chapter "Zeos now respects TField.ProviderFlags" will help you?

Best regards,

Jan

Another option might be to use TZUpdateSQL. There you can specify an operation to carry out on the database for each operation.

Hello jan

Yes, that fits, if I deleted "pfInUpdate" from the ProviderFlags, the field is not taken into account in the update. :D

Thanks

Alternative is to use threaded splash screen
