Type mismatch error in RB15.03, NexusDB V3.51, and XE5

edited March 2014 in End User
Hi,

I was attempting to run (print preview) an End User Report with datetime
search criteria using the latest ReportBuilder and NXDB releases in my
XE5 app and I encountered an error:

"NexusDB:: Query execution failed:
Error in statement: Type mismatch ['2012-03-31 00:00:00']

[$3CA0/15520]."

Could the datetime search criteria be missing the "Timestamp" prefix
when generating the SQL to textually represent a datetime?

I have also posted this to the NexusDB newsgroups and am seeing if they
have a solution. While I wait for an _official_ solution I may have
found a workaround/fix for the issue:

daSQL.pas function "FormatParamValue" (lines 6632 to 6796) looks control
how date/time parameters are structured. From line 6696 looks to have
database-specific date/time formatting depending on the DBMS used.
Modifying lines 6713 and 6731 to include "dtParadox, dtOther" appears to
allow the SQL generator to format the search criteria correctly [for use
in an NexusDB database]. Not ideal but it works for the moment.


Opening a report in ReportDesigner, and editing DataSettings, I am
unable to select dtNexusDB as a database type - only dtOther is
available. Also Session Type only has NexusDBSession available. Only
within XE5 under the Properties tab [when ppDesigner1 is selected] does
it list more options.

    Will,

    Make sure you are using the plug-in installed by ReportBuilder to Public
    Documents\RBuilder\XE5\Demos\EndUser Databases\NexusDB. There is a
    ReadMe.doc included and a full example for using the end-user components.

    For Delphi design-time install the packages. For run-time include daNexusDB
    in the 'uses'

    When you do the above, the Designer DataSettings SessionType can be set to
    NexusDBSession and once you configure that then the DatabaseType to
    dtNexusDB. These values are provided by the daNexusDB plug-in.

    daSQL contains special code for NexusDB, you can search the unit to find all
    occurrences. There is special formatting logic for dtNexusDB database type.

    Hi Nard,

    William,

    Has the DateTime format changed between Nexus 3 and Nexus 2? Please provide
    details of how version Nexus DB version 3 breaks compatibility with version
    2.

    For what its worth the daNexusDB is definitely more up to date than the
    one supplied by NexusDB. I use a RB supplied one, slightly modified to
    improve performance (blockreadsize set for some queries, NIL passed to
    TnxQuery.create()) and SQL type is set to sqSQL2 instead of the sqSQL1.
    Other than that its identical and works out of the box.

    Hi Nard,

    The datetime format is still the same however the NexusDB database was
    being handled as dtOther which meant the datetime formatting was being
    formatted incorrectly in daSQL.pas.

    Comparing the daNexusDB.pas files between the one provided in the latest
    NXDBV3 release and latest RBPro15 release there are a few distinct
    differences.

    RBPro15 daNexusDB.pas (modified 2006-04-26):
    - has an additional function ContainsSQLFunctionCall(..)
    - has a string array "NexusDBFunctions"
    - adds ".ZZZ" to time formatting (GetSearchCriteriaTimeFormat)
    - uses a TnxQuery (when NexusDBV2 detected) for collecting views in
    GetTableNames

    NexusDB V3 daNexusDB.pas (modified 2009-07-03):
    - uses nxllMemoryManager and replaces "FreeAndNil" with "nxFreeAndNil"
    - defines a constant dtNexusDB = dtOther
    - returns time formatting (GetSearchCriteriaTimeFormat) as "HH:NN:SS"


    You can probably see my hesitation to use the RB version by the large
    gap in the date modified on each daNexusDB.pas file. I am unsure what
    the absence of the ContainsSQLFunctionCall(..) function, or the
    differences in general, will do to end-user reporting functionality.


    Note: both "HH:NN:SS" and "HH:NN:SS.ZZZ" both appear valid when
    converting a string timestamp as shown by this example:

    select
    timestamp '2014-04-01 05:00:00'
    ,timestamp '2014-04-01 05:00:00.123'
    ,timestamp '2014-04-01 13:00:00'
    ,timestamp '2014-04-01 13:00:00.123'
    from #dummy;

    William, as I said earlier, I've been using the RB version of daNexus
    for yonks and I'm pretty sure its more up to date (in functionality
    terms) than the NexusDB one. It support "views" for one thing, and Nexus
    extensions like CURRENT_TIMESTAMP. I've tweaked it to make it a bit
    faster, but essentially it works properly.

    Cheers Paul,

    I did notice that there was an extra file in the RB folder
    (daNexusDBReg.pas). I'm considering doing a merge/sync of the NXDB and
    RB daNexusDB.pas files [into the NXDB file]. The missing
    "ContainsSQLFunctionCall" function in the NXDB one is a worry, as is the
    missing NexusDBFunctions array.

    Searching the RB dev guide PDF, it doesn't say what the differences are
    between SQL1 and SQL2, but to use SQL2 on more modern databases.

    I will give the RB install a go, though the installation instructions
    don't seem to apply to the new Win32/Win64 IDE.

    Thanks

    William,

    I recommend...

    - restoring daSQL.pas back to its original (and correct) state.

    - using the Dade NexusDB plugin installed with ReportBuilder, it supports
    the dtNexusDB DatabaseType. Using dtOther will produce incorrect SQL
    syntax - as you have experienced.

    Your issues are caused by using incorrect DADE plugin code. We only have
    resources to support the NexusDB plug-in code installed with RB. :)

    Are your "...NIL passed to TnxQuery.create()) and SQL type is set to
    sqSQL2 instead of the sqSQL1..." optimisations only made in
    daNexusDB.pas? I can see several references to "TnxQuery.Create(Self)"
    scattered throughout. Is it a 'search & replace' job for "sqSQL1" and
    "TnxQuery.Create(Self)"?

    Perhaps the RB devs will implement your changes (or ask for your
    daNexusDB.pas file?) in an upcoming update? :)

    I changed 3 methods (search for 'Tomsie'), changing sender to nil and
    setting blockreadsize:

    procedure TdanxSession.GetTableNames(const aDatabaseName: string; aList:
    TStrings);
    var
    lDatabase: TnxDatabase;
    {$IFDEF NEXUS2}
    lQuery: TnxQuery;
    {$ENDIF}
    begin

    {get the database}
    lDatabase := TnxDatabase(GetDatabaseForName(aDatabaseName));

    {Database must be active to get table names}
    lDatabase.Connected := True;

    {get list of table names from a table object}
    if lDatabase.Connected then
    lDatabase.GetTableNames(aList);

    {$IFDEF NEXUS2}
    {get list of view names from a query object}
    if (lDatabase.Connected) and not(lDatabase.ReadOnly) then
    begin
    {create a temporary NexusDB query}
    lQuery := TnxQuery.Create(nil);
    {Tomsie change for performance}
    lQuery.BlockReadSize := 1024*1024;

    try
    ....... etc
    endl

    procedure TdanxDataSet.GetFieldNamesForSQL(aList: TStrings; aSQL: TStrings);
    var
    lQuery : TnxQuery;
    begin
    aList.Clear;

    {create a temporary NexusDB query}
    {Tomsie changed Self to nil as its MUCH faster}
    lQuery := TnxQuery.Create(nil);
    {Tomsie change for performance}
    lQuery.BlockReadSize := 1024*1024;
    try
    ....... etc
    end;

    procedure TdanxDataSet.GetFieldsForSQL(aList: TList; aSQL: TStrings);
    var
    lQuery : TnxQuery;
    lField : TppField;
    liIndex : Integer;
    begin
    aList.Clear;

    {create a temporary NexusDB query}
    lQuery := TnxQuery.Create(nil);
    {Tomsie change for performance}
    lQuery.BlockReadSize := 1024*1024;

    Thanks Paul,

    I've now reverted to the RB source and implemented your speed
    tweaks...Only problem now is that I'm getting the "type mismatch" error
    again on my search criteria (!).

    Doing a trace I've discovered that the database type is still coming
    back as dtOther instead of dtNexusDB despite setting ppDesigner as
    dtNexusDB/SQL2/case insensitive.

    Adding a breakpoint to function TdanxSession.GetDatabaseType(...) and
    running in debug mode, it is not being called before determining the
    [print preview] report search criteria.

    The search [for what I've missed] continues...

    Hi William,

    To fix existing reports, open in the Designer and for each Query DataView,
    access the Query Designer and then select Ok. This will save the new
    DatabaseType as part of the query definition.

    Hi Nard,

    I get "Range check error" messages if I try your instructions in the
    64bit version of the application.
    I was able to do it in the 32bit version of our application however, and
    run the report successfully. The report was then able to be accessed in
    the 64bit version after that also.

    I'm hoping a similar solution will present itself with the internal
    (hard coded) RB reports I am getting "range check" errors on.

    Hi Nard,

    Since this issue started we have updated RBPro to 15.04 and NexusDB
    V4[.0005]. I've still got this error (see the exception log below).

    It seems to be related to how a datetime field is handled if used as a
    search item. The 'Print Preview' search window displays datetime fields
    with separate date and time components.

    I'm not sure what else to do. I've checked data settings and saved the
    report as the RB15 version but to no effect. I've also given the End
    User Reporting components their own connection/session to prevent
    threading issues, to no effect.

    I am using the DADE plugin you have supplied (in
    Users\Public\PublicDocuments\RBuilder\Delphi XE5\Demos\4. EndUser
    databases\NexusDB).

    There are no SQL syntax handling differences between NXDBV3 and NXDBV4
    as far as I know of.

    Hi William,

    I recommend re-reading this thread thoroughly. I just did and the all the
    answers are there.

    - for example, see my postApril 4 about fixing your existing reports and
    your reply....

    - you can trace the code in daSQL.pas, the method TdaSQL.FormatParamValue
    has the following code used to format date/datetime/time for NexusDB.if
    (DatabaseType in [dtNexusDB, dtElevateDB]) then
    begin
    case aDataType of
    dtDate: Result := 'DATE ' + '''' + FormatDateTime(lsDateFormat,
    lDateTime, ppFormatSettings) + '''';
    dtDateTime: Result := 'TIMESTAMP ' + '''' +
    FormatDateTime(lsDateFormat, lDateTime, ppFormatSettings) + ' ' +
    FormatDateTime(lsTimeFormat, lDateTime, ppFormatSettings) + '''';
    dtTime: Result := 'TIME ' + '''' + FormatDateTime(lsDateFormat,
    lDateTime, ppFormatSettings) + '''';
    end;
    end;


    - If your old reports are not getting into that logic, then you still have
    dtOther being used - which was the issue all along. These settings are saved
    down with your old report and you need to update them as above.

    - From April 4 post...

    Hi Nard

    I have done some more experimenting with ways to fix the old report and
    have managed to get the report working, but in order to do so I had to:

    - go to the Data tab
    - open each dataset
    - remove then re-add all data fields (by toggling the "All fields"
    checkbox does this quickly)
    - save the report
    (check that it worked by print previewing the report)

    Simply opening the Query designer and clicking OK was not enough in this
    case.


    Thanks and regards,
