1. IBExtract: Identity columns - add additional check for null column for generator name. |
4 |
> |
|
5 |
> |
2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses. |
6 |
> |
The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further |
7 |
> |
information). However, this is also a very useful mechanism for returning updated computed by |
8 |
> |
column values. Values returned as a result of executing an Insert or Update statement |
9 |
> |
replace existing values in the current row for each corresponding column. |
10 |
> |
|
11 |
> |
Previously, if a dataset's select query included read only (computed by) fields then |
12 |
> |
an automatic row refresh was performed after an insert or update query had been processed, |
13 |
> |
irrespective of the setting of the "ForcedUpdates" property. This has changed such |
14 |
> |
that an automatic refresh is no longer performed if an insert or update query contains |
15 |
> |
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 executing a refresh query. |
19 |
> |
|
20 |
> |
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. |
22 |
> |
|
23 |
> |
3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as |
24 |
> |
they are called when the dataset row is being deleted, there is no value in |
25 |
> |
updating the current record from the query result. Instead, a new event handler |
26 |
> |
"OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and |
27 |
> |
an OnDeleteReturning event handler is provided then it is called with the IResults returned |
28 |
> |
by the query. The event handler can then interrogate the query results and |
29 |
> |
perform whatever action is necessary. For example to confirm, to the user, |
30 |
> |
the deletion of a row with the returned values. |
31 |
> |
|
32 |
> |
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 |
34 |
> |
illustrate the computation of the employee Full Name on update. |
35 |
> |
|
36 |
> |
5. TIBTable: The GeneratorField property is now published. |
37 |
> |
|
38 |
> |
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. |
42 |
> |
|
43 |
> |
7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause. |
44 |
> |
Similarly Insert Property Editor now generates Insert SQL with Computed By fields in |
45 |
> |
Insert..Returning clause. |
46 |
> |
|
47 |
> |
8. TIBGenerator: small performance improvement by not preparing query each time |
48 |
> |
a new value is generated. |
49 |
> |
|
50 |
> |
9. TIBSQL: Free resources when transaction changed - ensures new transaction is used. |
51 |
> |
|
52 |
> |
10. Property editors will now sync table name to a System Table when "Include System |
53 |
> |
Tables" is selected and the query is for a System Table. |
54 |
> |
|
55 |
> |
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 |
> |
to TDateTime (the conversion to milliseconds is the default TDataset approach). |
58 |
> |
|
59 |
> |
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). |
64 |
> |
|
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 |
> |
|
70 |
> |
14. 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. |
74 |
> |
|
75 |
> |
15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting |
76 |
> |
for password on reconnect. |
77 |
> |
|
78 |
> |
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 |
82 |
> |
DB info lookups" |
83 |
> |
|
84 |
> |
18. IBExtract: now supports DDL Triggers. |

|
1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf |
90 |
|
changes. |
100 |
|
5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally |
101 |
|
results in autocomplete ignoring prefix text. |
102 |
|
|
103 |
+ |
6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when |
104 |
+ |
entering a new name into the text box. |
105 |
+ |
|
106 |
+ |
7. IBCustomDataset: ensure that TIBStringField uses the field size reported by |
107 |
+ |
Firebird rather than recomputing it. |
108 |
+ |
|
109 |
+ |
8. Property Editor positioning tidy up: All IBX Property editors should now be |
110 |
+ |
screen centre. Previously some were "poDesigned" which may be inappropriate |
111 |
+ |
for multi monitor desktops. |
112 |
+ |
|
113 |
+ |
10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node. |
114 |
+ |
|
115 |
+ |
11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending |
116 |
+ |
a transaction and always reset the object. |
117 |
+ |
|
118 |
+ |
12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows. |
119 |
+ |
|
120 |
+ |
13. TIBXScript: Allow for override of database filename in Create Database statements. |
121 |
+ |
|
122 |
+ |
14. IBLocaldb: Support initialisation of the database from an SQL script in addition |
123 |
+ |
to a gbak format archive. |
124 |
+ |
|
125 |
+ |
15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised. |
126 |
+ |
|
127 |
+ |
16. IBLocaldb: Drop database if error creating an empty database. |
128 |
+ |
|
129 |
+ |
17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset |
130 |
+ |
unless selected node not in current dataset. |
131 |
+ |
|
132 |
+ |
18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package) |
133 |
+ |
to TIBCustomService, and IBlocalDB code tidy up. |
134 |
+ |
|
135 |
+ |
19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable |
136 |
+ |
behaviour due to uninitialised variable. |
137 |
+ |
|
138 |
+ |
20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from |
139 |
+ |
integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode. |
140 |
+ |
|
141 |
+ |
21. IBSQL: When Database changed ensure that all resources are freed. |
142 |
+ |
|
143 |
+ |
22. IBCustomDataset: When database changed ensure that queries an unprepared. |
144 |
+ |
|
145 |
+ |
23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include: |
146 |
+ |
* Line Wrap on SQL Token boundaries (on user command) |
147 |
+ |
* auto-complete table names in drop down list of table names |
148 |
+ |
* Double click on tablename or field name adds to SQL text |
149 |
+ |
|
150 |
+ |
24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d). |
151 |
+ |
|
152 |
+ |
25. IBTreeView: Call to FindNode: param type change from "array of Variant" to |
153 |
+ |
TVariantArray. Seems to avoid memory corruption in Windows (probably a |
154 |
+ |
workaround for a problem in fpc 3.0.4 win64). |
155 |
+ |
|
156 |
+ |
26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open. |
157 |
+ |
|
158 |
+ |
27. IBDatabaseInfo: Remove memory leak when accessing database operation counts. |
159 |
+ |

161 |
|
|
162 |
|
1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to |
177 |
|
that BindFields is called when the query is next activated. Avoids FieldName |
178 |
|
not found error. |
179 |
|
|
180 |
+ |
7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general |
181 |
+ |
purpose and allows the programmer to define any action they want for Update, Insert |
182 |
+ |
or Delete. This may be complex SQL (similar to a Trigger), application specific |
183 |
+ |
filtering of updates, or use of statements such as Grant or Revoke instead of |
184 |
+ |
normal DML. See User Manual for more information. |
185 |
