I read some stuff on OBIEE Evaluate function and could not really understand as I am new to this.
EVALUATE('GetValue(%1,''SELECT MAX(P3_LST37) INTO :strValue FROM MV_ITEMSX WHERE ITEM_NUMBER = XXXX '' )' AS VARCHAR(2000), "Product")
Can you please help me to understand the function describe above?
Thanks
The Evaluate function enables you to send a function to the database to evaluate and return data to OBIEE. For security purposes you must use references in the function rather than the values themselves.
For example, if I have a column "Core"."Date" which returns the date as a string and want to use the TO_DATE function of evaluate, I would issue the following evaluate expression:
EVALUATE('TO_DATE(%1,'DD-MON-YYYY') AS DATE',"Core"."Date")
Hope that helps.

I have a statement like "Animal Association" from the database. I want to get its short form. It means, only the first letter of each word like this "AA". In the blade file, I got the whole statement as follows,
<p>{{ $animal->user->club->name}}</p>
So, how can I get a short form of this name?
Thank You!
If you are using MySQL 8+, then a raw select with REGEXP_REPLACE should work here:
$users = DB::table('animals')
->select(DB::raw("SELECT REGEXP_REPLACE(name, '(\\w)\\w+\\s*', '$1')"))
->get();
This very common problem where we ran into, I can provide you a function that will solve your problem. I am sharing two solutions and you can use any of these solutions.
using function
You can use this function in your model and solve your problem.
public function getNameAbbreviate($string){
$abbreviation = "";
$string = ucwords($string);
$words = explode(" ", "$string");
foreach($words as $word){
$abbreviation .= $word[0];
}
return $abbreviation;
}
There is probably no one-line solution, the solution which I provided is readable and understandable.
using regex
This solution is easy to apply and in case you can't make the first method work then go with this.
<p>{{ preg_split("/\s+/", $animal->user->club->name) }}</p>
using regex we can get a direct solution but I personally don't like it or recommend it.
I am trying to write logic for a search query. There are many different conditions with different parameters. One parameter sent from form is code. So there are code values in two different tables: competitions and responses. What I need is to check the params[:code] value first in competitions table and if it does not exist then check in responses table. If it does not exist in either table then it should return nil. I am trying to write it in a single if statement. The code I tried is below:
competitions = Competition.includes(:event, :responses)
if params[:code].present?
competitions = (competitions.where(code: params[:code])) ||
(competitions.joins(:responses).where(responses: { code: params[:code] }))
The above code checks only the value of competitions.where(code: params[:code]). If that value is [], then it is not evaluating the second condition. What changes should I do to make the above code work as per the requirements mentioned above?
competitions.where(code: params[:code]) returns a Relation object which is always truthy.
Luckily enough, it implements #presence method, returning either the value if it’s not blank, or nil. So, this should work:
competitions.where(code: params[:code]).presence || ...
Is there a way to escape a "?" in a eloquent whereRaw Statement? (Using laravel 6.x)
example:
ExampleModel::whereRaw(' "table"."json_field"::jsonb ?| array[\'test\', \'test2\'] ')->get();
This gets sent to the db as
where "table"."json_field"::jsonb $1| array['test', 'test2']
And well, thats not what i wanted to query...
Tried with '\?', put it in a binding (Laravel doc) - still no success.
Also i didn't find a reference in the docs ...
In my Usecase i want it to compare a json object with the psql comparing "?|" (Postgres Doc)
Thanks in advance!
the question is pretty old but my answer might help anyway.
The solution is very simple: just escape the questionmark with another questionmark.
The code of your example would look like this:
ExampleModel::whereRaw(' "table"."json_field"::jsonb ??| array[\'test\', \'test2\'] ')->get();
This solution has been tested with Laravel 7.28.3.
Didn't test but try using PDO:
$whereRaw = DB::connection()->getPdo()->quote(' "table"."json_field"::jsonb ?| array["test", "test2"] ');
ExampleModel::whereRaw($whereRaw)->get();
Well, didn't find an answer, but a workaround:
Don't use the question mark operators!
Instead i went for the named function. I found the named function via
SELECT
oprname,
oprcode || '(' || format_type(oprleft, NULL::integer) || ', '
|| format_type(oprright, NULL::integer) || ')' AS function
FROM pg_operator
WHERE oprname = '?|';
( Found there: big thanks to this guys post!)
So my Eloquent query now looks like:
ExampleModel::whereRaw('jsonb_exists_any("table"."json_field"::jsonb, array[\'test\', \'test2\'])')->get();
At least its working ¯\_(ツ)_/¯
How can I do the following:
data: ls_header type BAPIMEPOHEADER.
" fill it
write ls_header.
currently I'm getting an error because write can not parse the complex type to a string. Is there a simple way to get this code running in abap?
You could use something like:
DATA: g_struct TYPE bapimepoheader.
DO.
ASSIGN COMPONENT sy-index OF STRUCTURE g_struct TO FIELD-SYMBOL(<f>).
IF sy-subrc NE 0.
EXIT.
ENDIF.
WRITE: / <f>.
ENDDO.
Perhaps not exactly the answer you expect: If you list each field.
This can be done quite easy via the Pattern-mask in SE38:
Select the Write-pattern:
Enter the structure you want:
Select the fields
Confirm with "Copy"
Confirm and you get
WRITE: bapimepoheader-po_number,
bapimepoheader-comp_code,
bapimepoheader-doc_type,
bapimepoheader-delete_ind,
bapimepoheader-status,

Now you can make a simple replacement of bapimepoheader with ls_header and you have an output of all fields of the structure.
Maybe this is not elegant and you must adapt your report, if the structure changes. But I like this way, because often I don't need all fields and I can select the fields in an easy way.
I know two ways, one is procedural, the other is oop.
Here is the procedural approach.
Select the structure's fields (or whatever else You might need ) from the data-dictionary table DD03L into a local internal table.
Loop over the table into a work-area
Check, whether current field is a flat single datatype, and if so,
Assign component workarea-fieldname of structure ls_header into anyfieldsymbol
Write anyfieldsymbol
Do You need the code ?
Class CL_ABAP_CONTAINER_UTILITIES was specially introduced for that by SAP.
Use FILL_CONTAINER_C method for output the structure in a WRITE manner:
DATA: ls_header type BAPIMEPOHEADER.
CALL METHOD CL_ABAP_CONTAINER_UTILITIES=>FILL_CONTAINER_C
EXPORTING
IM_VALUE = ls_header
IMPORTING
EX_CONTAINER = DATA(container)
EXCEPTIONS
ILLEGAL_PARAMETER_TYPE = 1
others = 2.
WRITE container.
You can write your structure to a string and then output the string. Same method idoc segments are created.
I've got a function in an oracle database. I need to call it from delphi. I use the following code:
procedure TForm1.Run;
var
q:TADOQuery;
begin
q:=TADOQuery.Create(nil);
q.Connection:=ADOConnection1;
q.ParamCheck:=false;
q.SQL.Add('BEGIN');
q.SQL.Add(' :RES:=Search(:P_DATE);');
q.SQL.Add('END;');
q.Parameters.AddParameter.Name:='P_DATE';
q.Parameters.ParamByName('P_DATE').Direction:=pdInput;
q.Parameters.ParamByName('P_DATE').DataType:=ftDate;
q.Parameters.ParamByName('P_DATE').Value:=Now;
q.Parameters.AddParameter.Name:='RES';
q.Parameters.ParamByName('RES').DataType:=ftFloat;
q.Parameters.ParamByName('RES').Direction:=pdOutput;
q.Parameters.ParamByName('RES').Value:=1;
q.ExecSQL;
//...
I get ora-06550 error, saying invalid number or type of parameters. If I change the P_DATE parameter to sysdate, i.e. :RES:=Search(sysdate);, it works fine.
So how can I pass an "in" parameter of type DATE to an oracle function from delphi?
Found ORA-06550 when Oracle stored function is called.. However this relates to Kylix Pascal IDE. Am I expected to meet the same behaviour for delphi? Didn't try to use oracle procedure instead of a function. Maybe this issue can be solved some how else...
Oracle doesn't have a date type for bind variables - you need to explicitly convert the bind variable to a date:
:res := search(to_date(:p_date, 'dd/mm/yyyy'));
You should then be able to pass your variable as a string matching the date format you've specified.
Try to send this parameter as a string:
.........
q.SQL.Add('BEGIN');
q.SQL.Add(' :RES:=Search(TO_DATE(:P_DATE,''YYYYMMDD''));');
q.SQL.Add('END;');
q.Parameters.AddParameter.Name:='P_DATE';
q.Parameters.ParamByName('P_DATE').Direction:=pdInput;
q.Parameters.ParamByName('P_DATE').DataType:=ftString;
q.Parameters.ParamByName('P_DATE').Value:=FormatDateTime('yyyymmdd',Now);
..........
You're doing it wrong (and I think you had a previous question deleted as being a duplicate that asked this same question (different function, but same idea) just a couple of days ago).
You're calling the function wrong in the first place.
.........
q.SQL.Add('BEGIN');
q.SQL.Add(' SELECT Search(TO_DATE(:P_DATE,''YYYYMMDD'')) FROM System.Dual;');
q.SQL.Add('END;');
q.Parameters.AddParameter.Name:='P_DATE';
q.Parameters.ParamByName('P_DATE').Direction:=pdInput;
q.Parameters.ParamByName('P_DATE').DataType:=ftDate;
q.Parameters.ParamByName('P_DATE').Value:=Now;
q.Open;
if not q.IsEmpty then // or not q.Eof
Res := q.Fields[0].AsFloat;
