Improve naming mechanism of some components
Happy New Year to everyone !
I'm wondering if you can implement one new thing in your components...
TIBCDataSource put by a TIBCQuery makes automatically connection to this TIBCQuery. Could you extend this procedure by adding code that would name TIBCDataSource not standard IBCDataSource1 but eg. ds_ + name of Query component.
Example
I have IBCQuery component named qcompanies. New TIBCDataSource should be named dsqcompanies instead of IBCDataSource1.
If you are smart enough, you could recognize, that "q" a prefix of query component and name DataSource as ds_companies.It concern every your DAC component set.

Optimization (move from config to compiler preprocessor)
Create means to eliminate overhead at the compiler or configuration level. Compiler would be better because it would have 0 overhead in the resulting app; whereas config would have to check if the area was desired.
The use case for me is that I have an app, 100% non-visual. It runs as a batch job. This app could/should be able to run faster if it didn't bother doing things that a non-visual app doesnt care about. ie - master/detail.
Most libraries I have seen have a configurable .INC which control what the behavior is at compile time. This would be…

TUniLoader with Firebird - automaically calulate maximal value for RowsPerBatch
For Firebird the possible value for RowsPerBatch depends on the number of rows in the table because the maximal length of an SQL statement is 64KB.
For RowsPerBatch=0, UniDac should calculate the maximal possible value itself.2 votes -
TMSTableData Assign function not copy the data
The TMSTableData Component Assign function only copy the source table fields, but not copy the source data! I strongly recommend that can copy the all data like the TMSTable component.
for example:
self.MSTable1.First;
self.MSTableData1.Close;
self.MSTableData1.FieldDefs.Clear();
self.MSTableData1.Assign(self.MSTable1);
self.MSTableData1.Active:= true;The MSTableData1 not copy the MSTable1 data , but it copy the fields

Allow to connect with another Windows User
When TMSConnection.Authentication is auWindows the username is the currently logged in user, it woudl be good to have a way to connect as another user. There could be a new property TMSConnection.ImpersonateUser, if this is set and auWindows is set the connection will be done as if that user is logged in.

Do not create duplicate parameters when a parametername is used multiple times in a query text
When you have a query like
select *
from mytable
where COALESCE(DVALIDFROM, :PeriodTo) <= :PeriodToThen the params property of a TMSQuery component now contains the parameter 'PeriodTo' twice. This behaviour differs from the behaviour of TUniQuery. I think the behaviour of TMSQuery needs to be changed such that is has the behaviour of TUniQuery.

IBDAC - is there multiple overlapping transactions support ?
inidac page claims multiple transaction supports. IBDAC is rumored to be slcie of UniDAc but it does not claim overlapped and evenmere nested transactions support at http://www.devart.com/ibdac/features.html
I think that should be stated clearly whether this feature been removed from IBDAC or stays there.

Eliminate parethesis when using AddWhere
I would like complete control on how the parenthesis are added to the where clause. The way they are added now, it can result in a where clause that won't return what you're looking for.

How about including a version of Entity Developer?
Entity developer would be a great addition to Rad Studio for use with PGDac. Either with code generation, or just as a DB design tool.

Migration Wizard (Strip the .DB from tablenames if Paradox)
When converting from Paradox to SQLite, I ran into 2 problems.
1) the TableName.DB I used in paradox does NOT have a .DB ending in the actual tablename...
2) The data module where the "database1" was declared for the TUniConnection was not included in the files, and then the connections were not set to them. I had to open all the forms and remove the .db and set themI think that the Migration Wizard should handle those better...
