|
a returning clause that updates one or more fields on the current row. A full row |
| 16 |
|
refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any |
| 17 |
|
field values and the select query contains read only fields. Use of Insert/update |
| 18 |
< |
returning should be significantly more efficient than excuting a refresh query. |

returning should be significantly more efficient than executing a refresh query. |

|
This behaviour change is intended to be backwards compatible and there should be no need to change |
| 21 |
|
existing programs, other than to improve performance by using the new capability. |

| 24 |

they are called when the dataset row is being deleted, there is no value in |

"OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and |

an OnDeleteReturning event handler is provided then it is called with the IResults returned |

by the query. The event handler can then interrogate the query results and |

perform whatever action is necessary. For example to confirm, to the user, |

4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for |
| 33 |

any Computed By or Identity Columns. The IBTables example has been updated to |

6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List. |
| 39 |
|
When InsertSQL is generated, the Identity columns are not included in the list of values to |
| 40 |
|
be inserted. A RETURNING clause is added to the insert statement to return the value of |
| 41 |
|
each Identity column after the insert is executed. |

6. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause. |

7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause. |

Similarly Insert Property Editor now generates Insert SQL with Computed By fields in |
| 45 |

Insert..Returning clause. |

11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field |
| 56 |
|
values are no longer converted to milliseconds from TDateTime and then back again |
| 57 |

12. Property Editors handling of Stored Procedures. |
| 60 |
|
* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and |
| 61 |
|
which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select |
| 62 |
|
query). |
| 63 |
|
* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2). |

< |
12. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName |
| 65 |
> |
13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName |
| 66 |
|
can be used to select a package. If non-empty, the stored procedure name is |
| 67 |
|
expected to be a stored procedure defined in the specified package and the |
| 68 |
|
generated SQL will be as required for a stored procedure located in a package. |
| 69 |

13. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include |

| 71 |
|
a "Package Name" drop down box to allow selection of a Firebird 3 Package from |
| 72 |
|
which a stored procedure can be selected. With no package name selected, non-package |
| 73 |
|
stored procedures are listed. |

16. IBDatabase: use IAttachment for connection default character set id, code page |
| 79 |
+ |
and character set name. |
| 80 |

|
| 81 |

17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise |

DB info lookups" |

18. IBExtract: now supports DDL Triggers. |

19. Add a property Editor for TIBUpdate.RefreshSQL. |
| 87 |
+ |
|
| 88 |
+ |
20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input |
| 89 |
+ |
parameters. This stops an exception being raised when the field cannot be |
| 90 |
+ |
located in the record buffer. |
| 91 |
+ |
|
| 92 |
+ |
21. Property Editors now automatically include System Tables when opened and when the query table |
| 93 |
+ |
is a System Table. |
| 94 |
+ |
|
| 95 |
+ |
22. FB3UserManager example added to illustrate use if IBX for managing user logins, passwords |

and connections using IBX and with single or multiple security databases. |
