"text": "Please see the post of Mr James Bott here\n<!-- l --><a class=\"postlink-local\" href=\"http://forums.fivetechsupport.com/viewtopic.php?f=3&t=26787&p=149225&hilit=persisting+data#p149225\">viewtopic.php?f=3&t=26787&p=149225&hilit=persisting+data#p149225</a><!-- l -->\n\nPlease also see MSDN Article about Persisting recordsets on local disk\n[url:2m3m1qmi]http://msdn.microsoft.com/en-us/library/windows/desktop/ms675273(v=vs.85).aspx[/url:2m3m1qmi]\n\nWe can read recordset(s) from a remote server, save them locally and disconnect from the server. We can continue to work with the saved recordset(s) and if we make any modifications we can upload the modifications to the Server, when we next connect to server.\nThis feature is useful in remote locations where connectivity to main server is not reliable and need for update data is minimal.\n\nThis example shows how to use this feature. Experts in ADO who are wellversed with this feature need to read no further. This post is intended for starters of ADO and those who are not familiar with this feature.\n\nThis example does not use the FW_ ADO functions and users without these functions also can test this example.\n(This example uses only FW_CreateMDB function. If you do not have that function, you may use an alternative or use an exsisting MDB)\n\nThis example\n1. Creates a new MDB with a Table\n2. Connects to MDB, Opens the table in a recordset and displays in browse\n3. Saves the recordset locally. closes connection and renakes MDB as MDD. This is to sumulate non-availability of the server.\n4.and 5: Uses the local recordset to edit and add records locally\n6. Renaems MDD to MDB, Connects to Database and attaches the connection object to our local recordset Then all changes in the local recordset are UPLOADED to the Server.\n7. View the table on the server to confirm uploading all changes.\n\nPlease compile the program as it is and un in any folder you like.\nFor each step the program explains the stage of the program. It is better you keep the source code open and watch the same along with each step executed by the program.\n[code=fw:2m3m1qmi]<div class=\"fw\" id=\"{CB}\" style=\"font-family: monospace;\"><span

And even you do it, can you do it optimally and without errrors at all?\n\nWith the persistent recordset, you need to do only two operations:\noRs:ActiveConnection := <justopened connection object>\noRs:UpdateBatch()\n\nOfcourse you need to use TRY..CATCH for all ADO methods.\n\nYou may say that you do not want to modify the data but only want for reference. The why not GetRows() enough?\nYes but only for that session.\nWhen the user closes the application and reopens, the information in the array is lost.

All this is static information as at the time when we executed the query. The recordset does not get updated on its own unless we explicitly execute oRs:Requery() or in suitable cases oRs:ReSync().\n\nWith a view to keep our browse uptodate, we can not keep executing oRs:Requery() or oRs:Resync() continuously. What Mr Rick refers to is when to do this.\n\nXBrowse and TDataRow do this to some extent.

This can be done directly from ADORDD code or through a trigger or procedure in the server. We have to decide.\n\n4) Every time any replace, delete, addnew takes place the ADORDD first looks in NEEDREFRESH for the table \n\n5) If the datetime in NEEDREFRESH table is newer than the RDD area array element with the datetime last refresh of our recordset we refresh it again resetting the RDD area array element.\n\nOne can install a procedure at the server to run at certain hours when no one its connected to clean up this table.\n\nIts a trade off between integrity and speed.\n\nThis is only primary proposal study phase and at the end we might go other way.\nWe will start working it middle August.\n\nNevertheless I would like very much to have you opinion.",

The programmer anyway will face lots of problems and learn by mistakes. Anyway for small tables we may compare COUNT(*) with oRs:RecordCount() and decide, though it is slow and not foolproof.\n\nWhen opening a table it is easy for us to identify the primary key and also if it is auto-increment.\n\nSQLSERVER specific: In case the table has auto-increment primary key, we can use \"SELECT IDENT_CURRENT(‘tablename’)\" to know the last primary key value inserted. This is faster even than Max(PrimaryKey).\n\nSome programmers may use rowVersion or timestamp fields. It is possible to identify such fields while opening the table. In such cases comparing the max() values indicates activity by other users.\n\nNext question is how frequently we need to keep checking for other users' inserts. We can't keep checking continuously.\nIf the reocrdset is ordered on the primary key, it may be enough to check when (i) DBGOBOTTOM() and (ii) when DBSKIP( +n ) hits EOF.\nIn other cases we may need to do it with every SKIP() but this may slowdown the skips.

I go by your tests about the acceptability or otherwise of this approach from speed point of view.\n\nCan you please try this query for reliability and speed?\nSELECT `AUTO_INCREMENT` FROM INFORMATION_SCHEMA.TABLES\nWHERE TABLE_SCHEMA = 'DatabaseName' AND TABLE_NAME = 'TableName';\n\nBetter we do not interfere with triggers etc. Better to leave it to their database programmers.",

"text": "Buenas tardes, \nestoy comenzando a convertir mis bases de datos DBF a MYSQL.

I have come up with a table called [InvoiceNumbers] and when a person wishes to create a new Invoice, I open the [InvoiceNumber] table, go to the bottom in Ascending order and add a new record +1 and immediately assign the new transaction the next Invoice Number oRs:Update() .. and out, ready for the next transaction, which works quite will in a multi-user application. \n\nIf the User wishes to cancel the transaction before I commit the detail .. so be it. There is just a sequence gap in the committed Invoice transactions.\n\nRao does have a GOOD point about using an AutoNumber on the InvoiceNumber field letting the database issue the next number, however using AutoNumber especially on a primary key can EASILY lead to 'Sql Injection' from a malicious attacker that may ( covertly ) gain access to your system, as 'unlikely' as that may be .. Database Security is a BIG issue today and creating your Own Invoices Numbers under program control ( not database control ) is a good ( security ) selling point.\n\nRick Lipkin",

One of the potential problems that can arise with auto-increment fields is that if the table is later merged o copied to another table, append from another table, or transported somewhere else, or even if restructured -these numbers will change. i.e... you don't have any control over auto-increment fields.\n\nRestarting sequences every month will generate duplicated invoice numbers. I think you'd want to keep monthly sequences a part from invoice numbers which must be unique. \n\nIn this case I would declare the field as \"unique\" -that will ensure that even if badly coded, the invoice number will not be duplicated. It wouldn't be too hard to obtain the last invoice number used with a sql sentence using max. Then inside a transaction I would -try-and-retry to create the record with max(invoice#) + 1. The trying-and-re-trying inside a transaction will help solve the problem of other users racing to create an invoice # with the same number.\n\nI hope that helps.\n\n\nReinaldo.",

"text": "Hello everyone;\n\nAs you see from my previous posts, I do not like auto-increment fields as unique invoice numbers and I have explained why. I've also explained how a unique index on the invoice number can easily and safely solve the problem. \n\nOn this post I offer some SQL code (ADS compatible) that relies on a RowVersion field type to accomplish the same. This is how I use it on my applications. The idea here is to keep a single sequences table where all sequences are kept. The table fields are \"TableName\", \"FieldName\", \"Sequence\" and \"RowVersion\". This last field is of type row version. Whenever a new sequences for any given field on a table is needed, simply update the sequence by adding 1 as long as the rowversion field hasn't changed, we can guarantee no one else has changed the field on a race condition. \n\nJust like auto-inc fields rowversion fields are maintained by the SQL engine and incremented anytime a record is updated.\n\nHere is the code which explains itself a lot better than words:\n\n[code=fw:231a9f9o]<div class=\"fw\" id=\"{CB}\" style=\"font-family: monospace;\"><span style=\"color: #B900B9;\">//-------------------------------------------------</span><br /><span style=\"color: #B900B9;\">//</span><br />DECLARE @num INTEGER ;<br />DECLARE @rv INTEGER ;<br />DECLARE @numrows INTEGER ;<br />DECLARE @c CUROSR AS <span style=\"color: #0000ff;\">SELECT</span> <span style=\"color: #000000;\">[</span>sequence<span style=\"color: #000000;\">]</span>, <span style=\"color: #000000;\">[</span>rowversion<span style=\"color: #000000;\">]</span> <span style=\"color: #0000ff;\">FROM</span> sequences <span style=\"color: #0000ff;\">WHERE</span> table = :<span style=\"color: #000000;\">table</span> AND field = :<span style=\"color: #000000;\">field</span>;<br /><br />@numrows = <span style=\"color: #000000;\">0</span> ;<br /><br /><span style=\"color: #00C800;\">WHILE</span> @numrows=<span style=\"color: #000000;\">0</span> <span style=\"color: #00C800;\">DO</span><br /><br /> OPEN @c;<br /> FETCH @c;<br /><br /> @rv = @c.rowversion ;<br /> @num = @c.rowversion + <span style=\"color: #000000;\">1</span> ;<br /> CLOSE @c;<br /><br /> <span style=\"color: #B900B9;\">//if rowversion has changed then someone else has updated the record.</span><br /> <span style=\"color: #0000ff;\">UPDATE</span> Sequences SET <span style=\"color: #000000;\">[</span>Sequence<span style=\"color: #000000;\">]</span> = @num <span style=\"color: #0000ff;\">WHERE</span> <span style=\"color: #000000;\">[</span>rowversion<span style=\"color: #000000;\">]</span> = @rv; <br /><br /> @numrows = ::<span style=\"color: #000000;\">stmt</span>.UpdateCount ;<br /><br />END;<br /><span style=\"color: #0000ff;\">SELECT</span> @num <span style=\"color: #0000ff;\">FROM</span> system.iota ;<br /><span style=\"color: #B900B9;\">//-------------------------------------------------</span><br /> </div>[/code:231a9f9o]\n\nYou might have to translate this code into the SQL flavor being used but you get the idea.\n\nReinaldo.",

Since we can use both SQL tables and DBFs in the same app, I am thinking I can continue to use the same DBF which allows locking and thus is a simple solution.\n\nI also have a database class that has auto-incrementing using the above table, so I can solve the SQL auto-increment issue too. I think I can implement both of these with the new ADORDD by simply making one change--adding the VIA clause to the sequencing DBF, so that it is uses the DBFCDX RDD.\n\nJames",

This takes a fraction of a second.\n\nOver all the years I've used the system, with probably millions of invoices generated on systems from1 to 20 users, I've never had a single duplicate number generated.\n\nTim",
