1. TIBDatabase.CreateDatabase: extract full DB Name using reg ex in order to |
| 3 |
> |
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 excuting 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. TIBTable: generated Insert and Update SQL now include a RETURNING clause for |
| 24 |
> |
any Computed By or Identity Columns. The IBTables example has been updated to |
| 25 |
> |
illustrate the computation of the employee Full Name on update. |
| 26 |
> |
|
| 27 |
> |
4. TIBTable: The GeneratorField property is now published. |
| 28 |
> |
|
| 29 |
> |
5. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List. |
| 30 |
> |
When InsertSQL is generated, the Identity columns are not included in the list of values to |
| 31 |
> |
be inserted. A RETURNING clause is added to the insert statement to return the value of |
| 32 |
> |
each Identity column after the insert is executed. |
| 33 |
> |
|
| 34 |
> |
6. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause. |
| 35 |
> |
Similarly Insert Property Editor now generates Insert SQL with Computed By fields in |
| 36 |
> |
Insert..Returning clause. |
| 37 |
> |
|
| 38 |
> |
7. TIBGenerator: small performance improvement by not preparing query each time |
| 39 |
> |
a new value is generated. |
| 40 |
> |
|
| 41 |
> |
8. TIBSQL: Free resources when transaction changed - ensures new transaction is used. |
| 42 |
> |
|
| 43 |
> |
9. Property editors will now sync table name to a System Table when "Include System |
| 44 |
> |
Tables" is selected and the query is for a System Table. |
| 45 |
> |
|
| 46 |
> |
10. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field |
| 47 |
> |
values are no longer converted to milliseconds from TDateTime and then back again |
| 48 |
> |
to TDateTime (the conversion to milliseconds is the default TDataset approach). |
| 49 |
> |
|
| 50 |
> |
11. Property Editors handling of Stored Procedures. |
| 51 |
> |
* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and |
| 52 |
> |
which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select |
| 53 |
> |
query). |
| 54 |
> |
* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2). |
| 55 |
> |
|
| 56 |
> |
12. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName |
| 57 |
> |
can be used to select a package. If non-empty, the stored procedure name is |
| 58 |
> |
expected to be a stored procedure defined in the specified package and the |
| 59 |
> |
generated SQL will be as required for a stored procedure located in a package. |
| 60 |
> |
|
| 61 |
> |
13. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include |
| 62 |
> |
a "Package Name" drop down box to allow selection of a Firebird 3 Package from |
| 63 |
> |
which a stored procedure can be selected. With no package name selected, non-package |
| 64 |
> |
stored procedures are listed. |
| 65 |

1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf |
| 70 |
> |
changes. |
| 71 |
> |
|
| 72 |
> |
2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString. |
| 73 |
> |
Bug could result in truncated multi-byte character set values. |
| 74 |
> |
|
| 75 |
> |
3. Changes consequential on moving fbintf character set utility functions from |
| 76 |
> |
IFirebirdAPI to IAttachment. |
| 77 |
> |
|
| 78 |
> |
4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true |
| 79 |
> |
|
| 80 |
> |
5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally |
| 81 |
> |
results in autocomplete ignoring prefix text. |
| 82 |
> |
|
| 83 |
> |
6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when |
| 84 |
> |
entering a new name into the text box. |
| 85 |
> |
|
| 86 |
> |
7. IBCustomDataset: ensure that TIBStringField uses the field size reported by |
| 87 |
> |
Firebird rather than recomputing it. |
| 88 |
> |
|
| 89 |
> |
8. Property Editor positioning tidy up: All IBX Property editors should now be |
| 90 |
> |
screen centre. Previously some were "poDesigned" which may be inappropriate |
| 91 |
> |
for multi monitor desktops. |
| 92 |
> |
|
| 93 |
> |
10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node. |
| 94 |
> |
|
| 95 |
> |
11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending |
| 96 |
> |
a transaction and always reset the object. |
| 97 |
> |
|
| 98 |
> |
12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows. |
| 99 |
> |
|
| 100 |
> |
13. TIBXScript: Allow for override of database filename in Create Database statements. |
| 101 |
> |
|
| 102 |
> |
14. IBLocaldb: Support initialisation of the database from an SQL script in addition |
| 103 |
> |
to a gbak format archive. |
| 104 |
> |
|
| 105 |
> |
15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised. |
| 106 |
> |
|
| 107 |
> |
16. IBLocaldb: Drop database if error creating an empty database. |
| 108 |
> |
|
| 109 |
> |
17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset |
| 110 |
> |
unless selected node not in current dataset. |
| 111 |
> |
|
| 112 |
> |
18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package) |
| 113 |
> |
to TIBCustomService, and IBlocalDB code tidy up. |
| 114 |
> |
|
| 115 |
> |
19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable |
| 116 |
> |
behaviour due to uninitialised variable. |
| 117 |
> |
|
| 118 |
> |
20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from |
| 119 |
> |
integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode. |
| 120 |
> |
|
| 121 |
> |
21. IBSQL: When Database changed ensure that all resources are freed. |
| 122 |
> |
|
| 123 |
> |
22. IBCustomDataset: When database changed ensure that queries an unprepared. |
| 124 |
> |
|
| 125 |
> |
23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include: |
| 126 |
> |
* Line Wrap on SQL Token boundaries (on user command) |
| 127 |
> |
* auto-complete table names in drop down list of table names |
| 128 |
> |
* Double click on tablename or field name adds to SQL text |
| 129 |
> |
|
| 130 |
> |
24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d). |
| 131 |
> |
|
| 132 |
> |
25. IBTreeView: Call to FindNode: param type change from "array of Variant" to |
| 133 |
> |
TVariantArray. Seems to avoid memory corruption in Windows (probably a |
| 134 |
> |
workaround for a problem in fpc 3.0.4 win64). |
| 135 |
> |
|
| 136 |
> |
26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open. |
| 137 |
> |
|
| 138 |
> |
27. IBDatabaseInfo: Remove memory leak when accessing database operation counts. |

1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to |
| 143 |
|
include remote system name. |
| 144 |
|
|
| 145 |
|
2. TIBExtract: No longer include comment header and COMMIT statement for empty |
| 153 |
|
|
| 154 |
|
5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit |
| 155 |
|
|
| 156 |
+ |
6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures |
| 157 |
+ |
that BindFields is called when the query is next activated. Avoids FieldName |
| 158 |
+ |
not found error. |
| 159 |
+ |
|
| 160 |
+ |
7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general |
| 161 |
+ |
purpose and allows the programmer to define any action they want for Update, Insert |
| 162 |
+ |
or Delete. This may be complex SQL (similar to a Trigger), application specific |
| 163 |
+ |
filtering of updates, or use of statements such as Grant or Revoke instead of |
| 164 |
+ |
normal DML. See User Manual for more information. |
