We have hit problems using Access 97 as a front end to our contacts database. The limitations are in the functionality within the constructed interface, not an issue such as too many records (Although speed is also an issue here). We are therefore looking to other types of front-ends to replace Access. , Could anyone provide any relative Pros and Cons to using... , , Access 2000 , FoxPro , Oracle Forms , VB6 , HTML + ASP , C++ , J++ , Delphi , , .. to construct the front-end interface. Any pointers would be gratefully received! , , Thanks, , Paul

Hi, I am trying to send SQL queries to MS Access 97 using Java but I only seem to get any response if I have a simple query of the form SELECT * FROM CUSTOMERS., , If I want to send something just slightly more complicated then it doesn't work, for example SELECT SURNAME FROM CUSTOMERS., , The code that I am using is:, Statement stmt = dbCon.createStatement ();, ResultSet rs = stmt.executeQuery (sqlStatement); //error occurs here, ResultSetMetaData rsmd = rs.getMetaData();, , Is there a particular format that Access needs when sending a query or is this a problem with it?, , Thanks, Andrea

Does anyone have any experience with using MS SQL-server 2000 (or 7) for bulky databases (1 million+ customer register). It will recieve fairly complex statistical queries (eg. for finding customer behaviours and segmenting them)., How does it stand up to the challenge compared to eg. Oracle ?, Anything thats especially (maybe even notoriously) important to keep in mind with SQL-server ?, , Regards, , Torben Rohde, ------------ [URL=http://www.des.dk]www.des.dk[/URL]

I have the big problem, that my database has grown a lotsince installation time. Normally the db is about 500kB. We write some dates in one table. And when you start the Computer again, this table is empty. So the size of the db have to be always nearly the same. Now the gdb-file is about 2MB!! How can it be??, Exists a tool to clean the database of such effects (garbage in it, or something like that)?, , Thank U all, , Bruno

I am having trouble calling a SQL Server 7.0 Stored Procedure from C++ that returns a recordset and an output parameter., , Here's the criteria - I wish to bind parameters at run time and I need to return an output parameter. Presumably, I need to use rs.Open not execute in order to get the recordset - the problem is that I don't get the output parameters if I am opening the recordset., The stored procedure may change so I don't really want to implement a static wrapper for it., I have tried to implement this with ADO, MFC DAO and MFC ODBC support classes., , A sample piece of code that does exactly what I need would be ideal...

Suppose I have a table that looks like, , ID CAR1 CAR2 CAR3 ..., --------------------------------------, 001 HONDA PONTIAC FORD, 002 NISSAN TOYOTA HONDA, 003 MITSU MAZDA NISSAN, , etc..., , I want to build a query that retreives the total number of occurances of each type of car. For example,, , CAR COUNT, --------------, HONDA 2 , PONTIAC 1, NISSAN 2, MITZU 1, FORD 1, TOYOTA 1, MAZDA 1, , I know how to do it if there is only one column of CAR, however, I'm not sure when you have mulitple columns.

I develop system for stores still in CLipper 5.3 I will change to Delphi. Is the InterBase the best choice for use in customers that will not pay for traditional products as SQLServer and others ? Is IB faster enough to run in PIII 800Mhz 128 MB RAM as server for 2 to 10 machines in a LAN ? And does it keep fast even when grow about to 200,000 to 300,000 register in two or three tables ? My system handle 20 to 2000 register in terms of sells and 50 to 5000 registers in terms of selled products a day. If IB is not the best choice what should i use ?, Thank You !

I recently tried to create a new table using Corel Paradox 10. I chose INTERBASE (using the free Interbase 6 download)for the table type. One table was easily created, but a second table, where I chose DATE for the date field created an error, telling me that Interbase was using TIMESTAMP. Unfortunately, TIMESTAMP is not a choice on the field type dropdown dialogue. Going the otherway and using Interbase SQL, I could create a table with a DATE datetype, but Paradox wouldn't let me add it to the datamodel on a form. Any ideas how to get around this problem?, Would I still have the problem with the Corel Linux version and Interbase for FreeBSD/Linux? (I have Corel Office for Linux on order).

I have two clients conected to the same database. When a client update a record in a table, I don't know how to update the records for the other client (the client must refresh the data to update the records). How can I do this automatically?, Thanks in advance.

Hi there,, , I'm having trouble inserting a value into one of my interbase tables. The table in question has 5 fields, the primary key Operator_ID has a trigger set on it to autoincrement. It is a NOT NULL field as it is the primary key, so I don't enter a value via my Delphi front end. I have also set the required property for this field in Delphi to false., , I consistently am getting the message 'Field XXX requires a value however'., , Should interbase not handle this itself the trigger type is BEFORE INSERT. Within delphi I am using a DataModule with a an IBdatabase/IBTransaction/IBTable and a standard datasource as components and am attempting o do the insert via a navigation component and dbgrid. , , Any suggestions this thing is driving me crazy slowly but surely., , Thanks in advance, PL
