1 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

61 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
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.

101 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
102
103 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
104
105 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
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
115 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
116
117 1. Conditional compilation used to limit registration of TIntegerField to
118 Lazarus versions less than 1.1
119
120 2. When a database connection is created, character set is now by default set
121 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
122 1250 to 1254.
123
124
125 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
126
127 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
128
129
130 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
131
132 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
133 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
134
135 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
136 package is changed to do this (which it should do).
137
138 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
139
140 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
141
142 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
143
144 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
145
146 4. Property editors should now correctly resize.
147
148 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
149 (restored original functionality)
150
151 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
152 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
