1. IBExtract: Identity columns - add addition 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). Values returned as a result of executing an Insert or Update statement |
| 8 |
> |
replace existing values in the current row for each corresponding column. |
| 9 |
> |
|
| 10 |
> |
3. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List. |
| 11 |
> |
When InsertSQL is generated, the Identity columns are not included in the list of values to |
| 12 |
> |
be inserted. A RETURNING clause is added to the insert statement to return the value of |
| 13 |
> |
each Identity column after the insert is executed. |
| 14 |
> |
|
| 15 |
> |
4. TIBGenerator: small performance improvement by not preparing query each time |
| 16 |
> |
a new number is generated. |
| 17 |
> |
|
| 18 |
> |
5. TIBSQL: Free resources when transaction changed. |
| 19 |
> |
|
| 20 |
> |
6. Property editor will now sync table name to a System Table when "Include System |
| 21 |
> |
Tables" is selected and the query is for a System Table. |
| 22 |
> |
|
| 23 |
> |
7. Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause. |
| 24 |
> |
Similarly Insert Property Editor now generates Insert SQL with Computed By fields in |
| 25 |
> |
Insert..Returning clause |

1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf |
| 30 |
> |
changes. |
| 31 |
> |
|
| 32 |
> |
2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString. |
| 33 |
> |
Bug could result in truncated multi-byte character set values. |
| 34 |
> |
|
| 35 |
> |
3. Changes consequential on moving fbintf character set utility functions from |
| 36 |
> |
IFirebirdAPI to IAttachment. |
| 37 |
> |
|
| 38 |
> |
4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true |
| 39 |
> |
|
| 40 |
> |
5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally |
| 41 |
> |
results in autocomplete ignoring prefix text. |
| 42 |
> |
|
| 43 |
> |
6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when |
| 44 |
> |
entering a new name into the text box. |
| 45 |
> |
|
| 46 |
> |
7. IBCustomDataset: ensure that TIBStringField uses the field size reported by |
| 47 |
> |
Firebird rather than recomputing it. |
| 48 |
> |
|
| 49 |
> |
8. Property Editor positioning tidy up: All IBX Property editors should now be |
| 50 |
> |
screen centre. Previously some were "poDesigned" which may be inappropriate |
| 51 |
> |
for multi monitor desktops. |
| 52 |
> |
|
| 53 |
> |
10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node. |
| 54 |
> |
|
| 55 |
> |
11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending |
| 56 |
> |
a transaction and always reset the object. |
| 57 |
> |
|
| 58 |
> |
12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows. |
| 59 |
> |
|
| 60 |
> |
13. TIBXScript: Allow for override of database filename in Create Database statements. |
| 61 |
> |
|
| 62 |
> |
14. IBLocaldb: Support initialisation of the database from an SQL script in addition |
| 63 |
> |
to a gbak format archive. |
| 64 |
> |
|
| 65 |
> |
15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised. |
| 66 |
> |
|
| 67 |
> |
16. IBLocaldb: Drop database if error creating an empty database. |
| 68 |
> |
|
| 69 |
> |
17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset |
| 70 |
> |
unless selected node not in current dataset. |
| 71 |
> |
|
| 72 |
> |
18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package) |
| 73 |
> |
to TIBCustomService, and IBlocalDB code tidy up. |
| 74 |
> |
|
| 75 |
> |
19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable |
| 76 |
> |
behaviour due to uninitialised variable. |
| 77 |
> |
|
| 78 |
> |
20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from |
| 79 |
> |
integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode. |
| 80 |
> |
|
| 81 |
> |
21. IBSQL: When Database changed ensure that all resources are freed. |
| 82 |
> |
|
| 83 |
> |
22. IBCustomDataset: When database changed ensure that queries an unprepared. |
| 84 |
> |
|
| 85 |
> |
23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include: |
| 86 |
> |
* Line Wrap on SQL Token boundaries (on user command) |
| 87 |
> |
* auto-complete table names in drop down list of table names |
| 88 |
> |
* Double click on tablename or field name adds to SQL text |
| 89 |
> |
|
| 90 |
> |
24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d). |
| 91 |
> |
|
| 92 |
> |
25. IBTreeView: Call to FindNode: param type change from "array of Variant" to |
| 93 |
> |
TVariantArray. Seems to avoid memory corruption in Windows (probably a |
| 94 |
> |
workaround for a problem in fpc 3.0.4 win64). |
| 95 |
> |
|
| 96 |
> |
26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open. |
| 97 |
> |
|
| 98 |
> |
27. IBDatabaseInfo: Remove memory leak when accessing database operation counts. |

|
| 102 |
> |
1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to |
| 103 |
> |
include remote system name. |
| 104 |
> |
|
| 105 |
> |
2. TIBExtract: No longer include comment header and COMMIT statement for empty |
| 106 |
> |
tables when data included in output. |
| 107 |
> |
|
| 108 |
> |
3. Profiling: IBSQL now has conditional compilation flags to enable query performance |
| 109 |
> |
and timing information to be written to stdout. This may be used to locate |
| 110 |
> |
performance bottlenecks. |
| 111 |
> |
|
| 112 |
> |
4. SQLParser: only call "OnChanging" event handler when value is different. |
| 113 |
> |
|
| 114 |
> |
5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit |
| 115 |
> |
|
| 116 |
> |
6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures |
| 117 |
> |
that BindFields is called when the query is next activated. Avoids FieldName |
| 118 |
> |
not found error. |
| 119 |
> |
|
| 120 |
> |
7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general |
| 121 |
> |
purpose and allows the programmer to define any action they want for Update, Insert |
| 122 |
> |
or Delete. This may be complex SQL (similar to a Trigger), application specific |
| 123 |
> |
filtering of updates, or use of statements such as Grant or Revoke instead of |
| 124 |
> |
normal DML. See User Manual for more information. |

|
| 128 |
> |
1. TIBEvents: Fix uninitialised variable that could result in lost events. |
| 129 |
> |
|
| 130 |
> |
2. TIBExtract: Added support for FB3 "USAGE" privilege. |
| 131 |
> |
|
| 132 |
> |
3. TIBExtract: data formatted as Charset set "octets" is now output using |
| 133 |
> |
hexadecimal notation. |
| 134 |
> |
|
| 135 |
> |
4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements |
| 136 |
> |
using a simple XML format. |
| 137 |
> |
|
| 138 |
> |
5. TIBExtract: extract of individual Triggers and Stored Procedures can now include |
| 139 |
> |
grants to these objects. |
| 140 |
> |
|
| 141 |
> |
6. TIBExtract: Stored Procedures and Views output in dependency order to avoid |
| 142 |
> |
dependency problems restoring complex databases. |
| 143 |
> |
|
| 144 |
> |
7. TIBXScript: This component has been restructured to allow for the processing of |
| 145 |
> |
embedded XML in INSERT statements and to support interactive sources in addition |
| 146 |
> |
to non-interactive data sources such as files. |
| 147 |
> |
|
| 148 |
> |
8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported. |
| 149 |
> |
|
| 150 |
> |
9. TIBXScript: ISQL compatiable Set statements are now supported: |
| 151 |
> |
SET SQL DIALECT |
| 152 |
> |
SET TERM |
| 153 |
> |
SET AUTODDL |
| 154 |
> |
SET BAIL |
| 155 |
> |
SET ECHO |
| 156 |
> |
SET COUNT |
| 157 |
> |
SET STATS |
| 158 |
> |
SET NAMES <character set> |
| 159 |
> |
|
| 160 |
> |
10. IBVersion unit added to hold current IBX Version Number information. |
| 161 |
> |
|
| 162 |
> |
11. TIBExtract: Use character rather than byte length for VarChar procedure arguments., |
| 163 |
> |
and domain definitions. |
| 164 |
> |
|
| 165 |
> |
12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers |
| 166 |
> |
fully supported. |
| 167 |
> |
|
| 168 |
> |
13. TIBExtract: when a database dump includes data, the generator values are now also set. |
| 169 |
> |
|
| 170 |

See also doc/IBX4LazarusGuide.pdf for important information on |
| 175 |

upgrading to IBX2. |

1. Size property of TIBStringField is now the width in characters of the field |
| 178 |
> |
and not the byte length. This applies only to multi-byte character sets such |
| 179 |
> |
as UTF8. The original approach aligned with TStringField. However, the TStringField |
| 180 |
> |
code is not recognised as a bug and hence this change to align the behaviour. |
| 181 |
> |
The TStringField change is expected in fpc 3.2.0. |
| 182 |
> |
|
| 183 |
> |
2. A new property AutoFieldSize: boolean has been added to TIBStringField. When |
| 184 |
> |
true (default) then Size property value saved in the lfm is ignored. Size is |
| 185 |
> |
always set from the dynamic information read from the database. It is unclear |
| 186 |
> |
why anyone would want to override this and set Size to false. |
| 187 |
> |
|
| 188 |
> |
3. ibxscript: should now handle correctly a Case..End statement within a procedure |
| 189 |
> |
block. |
| 190 |
> |
|
| 191 |
> |
4. IBDatabase: new property - CreateIfNotExists. If true and database does not |
| 192 |
> |
exist when an attempt is made to connect to it (run time only) then an attempt |
| 193 |
> |
is made to create the database. |
| 194 |
> |
|
| 195 |
> |
5. IBDatabase: new event - OnCreateDatabase. This event is called after a database |
| 196 |
> |
has been successfully created as a result of a call to CreateDatabase or when |
| 197 |
> |
creating a database after it was found not to exist. |
| 198 |
> |
|
| 199 |
> |
6. DBControlGrid: a race condition could result in the wrong row image being |
| 200 |
> |
written to the cache. This has been avoided by a trip round the message |
| 201 |
> |
loop before rendering the row image. |
| 202 |
> |
|
| 203 |
> |
7. DBControlGrid: It is strongly recommended not to open the source DataSet for |
| 204 |
> |
a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is |
| 205 |
> |
known to risk corrupt rendering of row images when the control is first |
| 206 |
> |
displayed. If necessary use "Application.QueueAsyncCall" to delay opening |
| 207 |
> |
of the dataset (see DBControlGrid examples) until the Form's Window has been created. |
| 208 |
> |
|
| 209 |
> |
8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with |
| 210 |
> |
a TDateEdit control located on an editor panel. |
| 211 |
> |
|
| 212 |
> |
9. TIBExtract: brought up-to-date plus many bug fixes. |
| 213 |
> |
|
| 214 |
> |
10. DBControlGrid: Removed memory leak when updating rows. |
| 215 |
> |
|
| 216 |
> |
11. TIBCMLocalDBSupport: fixed invalid free on upgrade. |
| 217 |

1. IBCustomDataset: When calling SetCodePage, no longer request transliteration |
| 221 |
> |
when target codepage is CP_NONE. This is a workaround for |
| 222 |
> |
http://bugs.freepascal.org/view.php?id=30622. |
| 223 |
> |
|
| 224 |
> |
2. DBLog option removed from TIBStatisticalService - not supported by server |
| 225 |
> |
since Firebird 1.5. |
| 226 |
> |
|
| 227 |
> |
3. ibxscript: An error is no longer generated for "on commit preserve rows" or |
| 228 |
> |
similar. |
| 229 |
> |
|
| 230 |
> |
4. IBCodePage: updated mapping between codepages and character id. |
| 231 |
> |
|
| 232 |
> |
5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in |
| 233 |
> |
Firebird. Character sets with a char width of two are not UTF16. |
| 234 |
> |
|
| 235 |
> |
6. Strings received from the database are now always transliterated into UTF8 |
| 236 |
> |
regardless of the database character set or connection character set. This |
| 237 |
> |
is for compatibility with the LCL. |
| 238 |

1. IBBlob: Defer reading of blob until read method called. This avoids having to |
| 242 |
|
read in an entire blob just to get the size of the blob. General performance |
