Check if record has been changed

there are times when you want to check if a table has been touched
before you do a process such as a refresh. here is code that can be
placed in a table to check whether any data in the record set has been
changed

boolean hasChanged()
{
SysDictTable sysDictTable;
int f;
fieldId fieldId;
;

sysDictTable = new SysDictTable(this.TableId);

for (f = 1; f <= sysDictTable.fieldCnt(); f++)
{
fieldId = sysDictTable.fieldCnt2Id(f);

if (this.orig().(fieldId) != this.(fieldId))
return true;
}
return false;
}

Manually upgrade Date and Time fields

after an AX2009 upgrade, if you happen to forget to upgrade a Date and
Time field combination on a table to the new DateTime field, use this
simple job.

in the case below, SysDatabaseLog's CreatedTime did not seem to be
upgraded to be incorporated into the new CreatedDateTime field.

=======

static void AX2009Upgrade_ManuallyUpgradeDateTime(Args _args)
{
DEL_SysUpgradeTimeZone listOfColumnsToBeUpgraded;
ReleaseUpdateDB_TimezoneUpgrade timezoneUpgradeClass;
;

ReleaseUpdateDB41_Basic::upgradeToDateTime
(
tablenum(SysDatabaseLog),

fieldnum(SysDatabaseLog, CreatedDateTime),

fieldnum(SysDatabaseLog, CreatedDateTime),

fieldnum(SysDatabaseLog, DEL_CreatedTime)
);

while
select
listOfColumnsToBeUpgraded
order by
listOfColumnsToBeUpgraded.RefTableId
where
listOfColumnsToBeUpgraded.Status == SysUpgradeTimeZoneStatusEnum::Ready
{
timezoneUpgradeClass =
ReleaseUpdateDB_TimezoneUpgrade::construct(
listOfColumnsToBeUpgraded.data() );
timezoneUpgradeClass.run();
}
pause;
}

How to recover database from MDF in SQL Server without an LDF

because there are times when you need to do something dodgy to save the day.

1. Detach database and move your mdf to save location.
2. Create new database of same name, same files, same file location
and same file size.
3. Stop SQL server.
4. Swap mdf file of just created DB to your save one.
5. Start SQL. DB will go suspect.
6. ALTER DATABASE yourdb SET EMERGENCY
7. ALTER DATABASE yourdb SET SINGLE_USER
8. DBCC CHECKDB (yourdb, REPAIR_ALLOW_DATA_LOSS)
9. ALTER DATABASE yourdb SET MULTI_USER
10. ALTER DATABASE yourdb SET ONLINE

Creating XML in the new AX

good info

Wrong argument types for comparison

this is not the first time this piece of code has helped me to get rid
of a weird error:

ERROR:
Error executing code: Wrong argument types for comparison.

Stack trace:
(C) \Classes\QueryRun\next
(C) \Classes\FormDataSource\executeQuery
(C) \Forms\MyForm\Data Sources\MyFormDatasource\Methods\executeQuery - line 4
(C) \Classes\FormDataSource\linkActive
(C) \Forms\MyForm\Data Sources\MyFormDatasource\Methods\linkActive - line 3

SOLUTION:
on the form init,

public void init()
{
super();
this.query().dataSourceNo(1).clearDynalinks();
}

Counting how long a job takes

use this code to keep track of how long a piece of code takes to execute

timeofday starttime = timenow();
;
//your cool code here

info(strfmt("Total time taken: %1", time2StrHMS(timenow() - starttime)));
