1. TIBXDataSet and Generators: Generator Names that are not all upper case or |
| 4 |
> |
not SQL Identifiers are now supported. |
| 5 |
> |
|
| 6 |
> |
2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is |
| 7 |
> |
passed to the Firebird engine for execution. |
| 8 |
> |
|
| 9 |
> |
3. TIBDataSet: Unidirectional datasets now give an error message if an attempt |
| 10 |
> |
is made to scroll back. |
| 11 |
> |
|
| 12 |
> |
4. New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf |
| 13 |
> |
|
| 14 |
> |
5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now |
| 15 |
> |
only enclosed in double quotes in SQL dialect 3 and when it needs to be. |
| 16 |
> |
|
| 17 |
> |
6. TIBLookupComboEditBox: when the list source opens, the ListField name is now |
| 18 |
> |
validated. If no match is found in the list of field names and the database has |
| 19 |
> |
been opened in SQL Dialect 3, then the ListField Name is converted to upper case |
| 20 |
> |
if it then matches a field name. Otherwise, a Listfield not valid exception occurs. |
| 21 |
> |
|
| 22 |

1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides" |
| 29 |
> |
and is used to override the default settings in the client side "firebird.conf" This |
| 30 |
> |
includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings". |
| 31 |
> |
Each line of the string list should be a setting in the same format as "firebird.conf". |
| 32 |
> |
For example "WireCompression = true" in order to request wire compression on the client side. |
| 33 |
> |
|
| 34 |
> |
Note: explicit settings in the client side "firebird.conf" appear to take precedence |
| 35 |
> |
over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings |
| 36 |
> |
also require a compatible setting in the server side "firebird.conf". For example |
| 37 |
> |
"WireCompression = true" must also be set in the server's "firebird.conf" for wire |
| 38 |
> |
compression to be used. |
| 39 |
> |
|
| 40 |
> |
Whether or not WireCompression or WireCrypt are in use can be checked using the information |
| 41 |
> |
returned with the Client/Server protocol version. See ibx/examples/dbadmin and |
| 42 |
> |
ibx/examples/dbinfo for examples of how to display this information. |
| 43 |
> |
|
| 44 |
> |
2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This |
| 45 |
> |
is a "convenience" property. If set the "WireCompression=true" is added to the |
| 46 |
> |
ConfigOverrides. If unchecked then this setting is removed. |
| 47 |
> |
|
| 48 |
> |
3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and |
| 49 |
> |
not "INT64". |
| 50 |
> |
|
| 51 |
> |
4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut |
| 52 |
> |
These are: |
| 53 |
> |
property TimestampFormat: string; |
| 54 |
> |
property DateFormat: string; |
| 55 |
> |
property TimeFormat: string; |
| 56 |
> |
|
| 57 |
> |
Respectively, these provide the date time format templates for SQL types: TIMESTAMP, |
| 58 |
> |
DATETIME and TIME. The format strings use the standard FPC date/time format |
| 59 |
> |
characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html). |
| 60 |
> |
|
| 61 |
> |
If any of the above properties are set to an empty string, then the locale default |
| 62 |
> |
is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the |
| 63 |
> |
locale default is extended by appending '.zzz' to include milliseconds. |
| 64 |
> |
|
| 65 |
> |
TIBCSVDataOut by default sets these properties to the empty string, while the other |
| 66 |
> |
two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively. |
| 67 |
> |
|
| 68 |
> |
5. New published property for TIBCSVDataOut: |
| 69 |
> |
property QuoteStrings: boolean (default true) |
| 70 |
> |
|
| 71 |
> |
If false then strings are unquoted, otherwise, the QuoteChar property value is |
| 72 |
> |
used to delimit each and every string in the output. |
| 73 |
> |
|
| 74 |
> |
6. New published properties for TIBCSVDataOut: |
| 75 |
> |
property FieldSeparator: string; |
| 76 |
> |
property HeaderSeparator: string; |
| 77 |
> |
|
| 78 |
> |
Respectively, these provide the separator character(s) used to separate fields |
| 79 |
> |
in data and header rows. Both default to ','. |
| 80 |
> |
|
| 81 |
> |
7. New published properties for TIBCSVDataOut and TIBBlockFormatOut: |
| 82 |
> |
TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object; |
| 83 |
> |
property OnFormatTextString; |
| 84 |
> |
|
| 85 |
> |
This event handler can be used to process text strings before they are included |
| 86 |
> |
in the output e.g. to replace unprintable characters with alternative strings. |
| 87 |
> |
This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT. |
| 88 |
> |
|
| 89 |
> |
8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name. |
| 90 |
> |
Uses "FindParam" if in order to find out if a parameter with a given name exists |
| 91 |
> |
and without raising and exception if it does not. |
| 92 |
> |
|
| 93 |
> |
9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure |
| 94 |
> |
consistency with SQL queries. |
| 95 |
> |
|
| 96 |
> |
10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery. |
| 97 |
> |
When true, SQL statement parameter names are parsed case sensitive. Note for |
| 98 |
> |
TIBDataSet only applies to Select query. |
| 99 |
> |
|
| 100 |
> |
11. IBEvents: removing a TIBEvent component from a form should no longer result in |
| 101 |
> |
an IDE exception. |
| 102 |
> |
|
| 103 |
> |
12. LocalDBSupport: initial database creation should now work correctly |
| 104 |
> |
when the schema source is an sql file. |
| 105 |
> |
|
| 106 |
> |
13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent" |
| 107 |
> |
when defined, this handler will be called by the internal TIBXScript during |
| 108 |
> |
initial database creation when the schema source is an sql file and may be used |
| 109 |
> |
to provide a visual indication of progress in console mode. |
| 110 |
> |
|
| 111 |
> |
14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set |
| 112 |
> |
to true while a new local database is being created and its schema populated. |
| 113 |
> |
Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions |
| 114 |
> |
when the database is disconnected/connected during the create DB procedure. |
| 115 |
> |
|
| 116 |
> |
15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement |
| 117 |
> |
are now always ignored and replaced by the user name and password provided as |
| 118 |
> |
the login parameters for the TIBDatabase referenced from the TIBXScript. The |
| 119 |
> |
IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is |
| 120 |
> |
completely ignored if this property is true. |
| 121 |
> |
|
| 122 |
> |
16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes |
| 123 |
> |
to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise |
| 124 |
> |
ImageIndex and SelectImageIndex values on AddNode. |
| 125 |
> |
|
| 126 |
> |
17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now |
| 127 |
> |
read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share |
| 128 |
> |
the same database connection. |
| 129 |
> |
|
| 130 |
> |
18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property. |
| 131 |
> |
if provided, this should be an conditional SQL expression suitable for |
| 132 |
> |
including in an SQL Select statement "where" clause. If non-empty and the |
| 133 |
> |
"Filtered" property is true then the SQL expression provided as the value of |
| 134 |
> |
the "Filter" property is "ANDed" with any existing condition statement |
| 135 |
> |
in the SQL statement's "Where" clause. |
| 136 |
> |
|
| 137 |
> |
If the "Filter" property is set at run time, the "Filtered" property is true |
| 138 |
> |
and the dataset is already open, then the dataset is closed and re-opened automatically. |
| 139 |
> |
|
| 140 |
> |
The "Filter" condition may include IBX style parameters. In which case, their |
| 141 |
> |
value must be set by the dataset's "OnBeforeOpen" event handler. |
| 142 |
> |
|
| 143 |
> |
This is a public property for TIBDataSet and TIBQuery query and intended for |
| 144 |
> |
use at run time. |
| 145 |
> |
|
| 146 |
> |
Note: The property is a published property of TIBTable. The TIBTable functionality |
| 147 |
> |
is unaffected by this change. |
