IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000 |
| 2 |
+ |
|
| 3 |
+ |
1. An internal select SQL Parser is now available for TIBCustomDataset descendents. |
| 4 |
+ |
This is typically used during an "OnBeforeOpen" event handler to manipulate the |
| 5 |
+ |
"Where" and "Having" clauses to implement user specified filters of arbitrary |
| 6 |
+ |
complexity. |
| 7 |
+ |
|
| 8 |
+ |
2. A new Component Palette entry "Firebird Data Controls" is now available. This has |
| 9 |
+ |
three new data aware controls dependent on IBX and which make use of the SQL Parser. |
| 10 |
+ |
These are: |
| 11 |
+ |
|
| 12 |
+ |
- TIBLookupComboEditBox |
| 13 |
+ |
- TIBDynamicGrid |
| 14 |
+ |
- TIBTreeview |
| 15 |
+ |
|
| 16 |
+ |
TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete" |
| 17 |
+ |
of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation |
| 18 |
+ |
to revise the available list and restrict it to items that are prefixed by the |
| 19 |
+ |
typed text (either case sensitive or case insenstive). Autoinsert allows a |
| 20 |
+ |
newly typed entry to be added to the list dataset and included in the available |
| 21 |
+ |
list items. |
| 22 |
+ |
|
| 23 |
+ |
TIBDynamicGrid is a TDBGrid descendent that provides for: |
| 24 |
+ |
- automatic resizing of selected columns to fill the available row length |
| 25 |
+ |
- automatic positioning and sizing of a "totals" control, typically at the |
| 26 |
+ |
column footer, on a per column basis. |
| 27 |
+ |
- DataSet resorting on header row click, sorting the dataset by the selected column. |
| 28 |
+ |
A second click on the same header cell reversed the sort order. |
| 29 |
+ |
- Support for a "Panel Editor". That is on clicking the indicator column, the row |
| 30 |
+ |
is automatically expanded and a panel superimposed on it. The panel can have any |
| 31 |
+ |
number of child controls, typically data aware controls with the same datasource |
| 32 |
+ |
as the grid allowing for editing of additional fields and more complex editors. |
| 33 |
+ |
- Reselection of the same row following resorting. |
| 34 |
+ |
- A new cell editor that provides the same functionality as TIBLookupComboEditBox. |
| 35 |
+ |
Its properties are specified on a per column basis and allows for one or more |
| 36 |
+ |
columns to have their values selected from a list provided by a dataset. |
| 37 |
+ |
Autocomplete and autoinsert are also available. The existing picklist editor |
| 38 |
+ |
is unaffected by the extension. |
| 39 |
+ |
|
| 40 |
+ |
TIBTreeView is a data aware TCustomTreeView. |
| 41 |
+ |
|
| 42 |
+ |
3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a |
| 43 |
+ |
zero scale will no longer return an error. An Int64 will be returned instead. |
| 44 |
+ |
|
| 45 |
+ |
4. TIBTransaction now has events for Before and After Transaction End and a new function |
| 46 |
+ |
"GetEndAction" allowing the EndAction to be accessed by these event handlers. |
| 47 |
+ |
|
| 48 |
+ |
5. TIBQuery can now handle correctly queries which contain the same keyword parameter |
| 49 |
+ |
repeated multiple times. |
| 50 |
+ |
|
| 51 |
+ |
6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error |
| 52 |
+ |
check used to get in the way of using Stored Procedures, and "Update or Insert" |
| 53 |
+ |
statements. |
| 54 |
+ |
|
| 55 |
+ |
7. Insert, Modify and Delete property Editors now support Query Generation from |
| 56 |
+ |
Stored Procedures. |
| 57 |
+ |
|
| 58 |
+ |
8. Three new examples illustrate the use of the new IB Controls |
| 59 |
+ |

| 62 |
+ |
|
| 63 |
+ |
1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter |
| 64 |
+ |
setting performance. See "readme.field+param.names in the doc folder.(Thanks to |
| 65 |
+ |
Gabor Boros for reporting this problem and for testing the improvements). |
| 66 |
+ |
|
| 67 |
+ |
2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case. |
| 68 |
+ |
See readme.field+param.names in the doc folder. |
| 69 |
+ |
|
| 70 |
+ |
3. IBX SQL Editors will now automatically add double quotes around column names when the database |
| 71 |
+ |
dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word. |
| 72 |
+ |
|
| 73 |
+ |
4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc |
| 74 |
+ |
|
| 75 |
+ |
5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once" |
| 76 |
+ |
actions. |
| 77 |
+ |
|
| 78 |
+ |
6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with |
| 79 |
+ |
thanks to Yuriy Kopnin for pointing this out). |
| 80 |
+ |
|
| 81 |
+ |
7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet. |
| 82 |
+ |
|
| 83 |
+ |
8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types |
| 84 |
+ |
for both fields and parameter setting. |
| 85 |
+ |
|
| 86 |
+ |
9. Changes to the Select SQL in an IBCustomDataset descendent should now be |
| 87 |
+ |
visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property. |
| 88 |
+ |
|
| 89 |
+ |
10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test, |
| 90 |
+ |
when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true. |
| 91 |
+ |
|
| 92 |
+ |
11. TIBTable now has a property editor for "MasterFields" |
| 93 |
+ |
|
| 94 |
+ |
12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the |
| 95 |
+ |
GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters. |
| 96 |
+ |
|
| 97 |
+ |
13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination |
| 98 |
+ |
of settings is unrecognised. Selecting this radio button has no effect on the settings. |
| 99 |
+ |
|

| 106 |
+ |
|
| 107 |
+ |
1. In a TIBCustomDataset descendent, a generator now only sets the value when |
| 108 |
+ |
it is null. This allows for alternative user defined setting of the generator |
| 109 |
+ |
|
| 110 |
+ |
Many thanks to Julio Jiménez for this fix |
| 111 |
+ |
|
| 112 |
+ |
2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library |
| 113 |
+ |
and suggests that the user may have forgotten to install it. |
| 114 |
