A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike + rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid + that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row + correspondes to a row of the linked DataSource. Any data aware control on the + replicated (e.g.) TPanel will then appear to have the appropriate value for the row. + +2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase. + When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change + takes place during database access. This may be useful when there are performance issues with + the change of cursor. Setting the property to false suppresses the change of cursor. + +3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery + and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to + Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of + making all changes permanent immediately rather than when the transaction is explicitly + committed. + +4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still + using the legacy Firebird API. Thanks to Gabor Boros for helping to this feature. + +IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000 + +Development version only. + +IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000 + +1. An internal select SQL Parser is now available for TIBCustomDataset descendents. + This is typically used during an "OnBeforeOpen" event handler to manipulate the + "Where" and "Having" clauses to implement user specified filters of arbitrary + complexity. + +2. A new Component Palette entry "Firebird Data Controls" is now available. This has + three new data aware controls dependent on IBX and which make use of the SQL Parser. + These are: + + - TIBLookupComboEditBox + - TIBDynamicGrid + - TIBTreeview + + TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete" + of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation + to revise the available list and restrict it to items that are prefixed by the + typed text (either case sensitive or case insensitive). Autoinsert allows a + newly typed entry to be added to the list dataset and included in the available + list items. + + TIBDynamicGrid is a TDBGrid descendent that provides for: + - automatic resizing of selected columns to fill the available row length + - automatic positioning and sizing of a "totals" control, typically at the + column footer, on a per column basis. + - DataSet resorting on header row click, sorting the dataset by the selected column. + A second click on the same header cell reversed the sort order. + - Support for a "Panel Editor". That is on clicking the indicator column, the row + is automatically expanded and a panel superimposed on it. The panel can have any + number of child controls, typically data aware controls with the same datasource + as the grid allowing for editing of additional fields and more complex editors. + - Reselection of the same row following resorting. + - A new cell editor that provides the same functionality as TIBLookupComboEditBox. + Its properties are specified on a per column basis and allows for one or more + columns to have their values selected from a list provided by a dataset. + Autocomplete and autoinsert are also available. The existing picklist editor + is unaffected by the extension. + + TIBTreeView is a data aware TCustomTreeView. + +3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a + zero scale will no longer return an error. An Int64 will be returned instead. + +4. TIBTransaction now has events for Before and After Transaction End and a new function + "GetEndAction" allowing the EndAction to be accessed by these event handlers. + +5. TIBQuery can now handle correctly queries which contain the same keyword parameter + repeated multiple times. + +6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error + check used to get in the way of using Stored Procedures, and "Update or Insert" + statements. + +7. Insert, Modify and Delete property Editors now support Query Generation from + Stored Procedures. + +8. Three new examples illustrate the use of the new IB Controls + + +IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100 + +1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter + setting performance. See "readme.field+param.names in the doc folder.(Thanks to + Gabor Boros for reporting this problem and for testing the improvements). + +2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case. + See readme.field+param.names in the doc folder. + +3. IBX SQL Editors will now automatically add double quotes around column names when the database + dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word. + +4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc + +5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once" + actions. + +6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with + thanks to Yuriy Kopnin for pointing this out). + +7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet. + +8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types + for both fields and parameter setting. + +9. Changes to the Select SQL in an IBCustomDataset descendent should now be + visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property. + +10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test, + when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true. + +11. TIBTable now has a property editor for "MasterFields" + +12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the + GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters. + +13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination + of settings is unrecognised. Selecting this radio button has no effect on the settings. + + IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
