I am new to using Talend.
The first table is fed into tHashOutput1. This part works fine.
The tHashOutput1 is fed into tHashOut2 and tHashOutput3.
From tMap_3 is fed from user . When i try to feed tHashInput3 into the tMap i am not allowed to do this. What is wrong with this.
Please make sure that tHashInput3have the schema of tHashOutput1, as you can see there is a small yellow warning on the tHashInput3 but it not exist on tHashInput2. Also, there is no output from the tMap3 to see if it works.

so here's my problem. The below works:
=DLookUp("[CylindersCompleted]","WO_User_Input_Save","WorkOrder=331091")
Unfortunately I need 331091 to be Combo4. Once I change the formula to:
=DLookUp("[CylindersCompleted]","WO_User_Input_Save","WorkOrder"= [Combo4]") or
=DLookUp("[CylindersCompleted]","WO_User_Input_Save","WorkOrder"= Combo4) or
=DLookUp("[CylindersCompleted]","WO_User_Input_Save","[WorkOrder]"= [Combo4])
=DLookUp("[CylindersCompleted]","WO_User_Input_Save","[WorkOrder]= [Combo4]")
I've been testing all the variations in Immediate Window and all result in Compile error: Expected: expression. Getting the same error in my other database which is why I created this one. One table, one record along with one unbound form. Table has WorkOrder and CylindersCompleted which are both Number and the form has one Combo and one textbox which are both Number. I'm putting the Dlookup formula in the Control Source of the textbox. I'm hoping someone can help me solve this issue so I can apply it to my other database which is much more complicated. Thanks in advance.
=DLookUp("[CylindersCompleted]","WO_User_Input_Save","WorkOrder"= [Combo4]")
Should be:
=DLookUp("[CylindersCompleted]","WO_User_Input_Save","WorkOrder=" & [Combo4])
In original script there is part of code where is this
filepathsource='C:\Users\...';
strFP=dir([filepathsource '*.txt']);
Which works nicely.
Problem is that i need to change that filepathsource to some more dynamic so i did.
filepathsource=string(strcat(app.folderPath,'\',string(app.currentCount),'\'));
strFP=dir([filepathsource '*.txt']);
But i end with error
Error using dir
Name must be a text scalar.
And i need original formating because i get errors later in script. Is there any way how can i fix it? I tried everything but always is something somewhere wrong. And i just dont understand whats difference between original filepathsource and the one that i created bot are strings. (output of my filepathsource is correct when i display it)
I am trying to run below code to read all csv files available at location C:/q/BitCoin/Input.Getting an error and dont know what the solution is?csv files are standard ones with three fields.
raze{[x]
inputdir:`:C:/q/BitCoin/Input;
filelist1:key inputdir;
filelist2:` sv' inputdir,'filelist1;
filelist3:string filelist2;
r:flip`Time`Qty`Price!("ZFF";",")0:x;
select from r
} each `$filelist3
Hard coding the file names and running below code works but I don't want to hard code
raze {[x]
r:flip`Time`Qty`Price!("ZFF";",")0:x;
select from r
} each (`$"C:/q/BitCoin/Input/bitbayPLN.csv";`$"C:/q/BitCoin/Input/anxhkAUD.csv")
Getting below error
An error occurred during execution of the query.
The server sent the response:
filelist3
Can someone help with issue?
The reason that you are receiving the error 'filelist3 is because filelist3 is defined in the lambda and outside of the lambda it is not recognised or defined. There are various ways to overcome this as outlined below.
Firstly you can essentially take all of the defined work done on the inside of the lambda and put it on the right side of the each.
raze{[x] r:flip`Time`Qty`Price!("ZFF";",")0:x; select from r
} each `$(string (` sv' `:C:/q/BitCoin/Input,'(key `:C:/q/BitCoin/Input)))
Or if you wanted to you could create a function which will generate filelist3 for you and use that on the right hand side of the each also.
f:{[inputdir] filelist1:key inputdir; filelist2:` sv' inputdir,'filelist1; filelist3:string filelist2; filelist3}
raze{[x] r:flip`Time`Qty`Price!("ZFF";",")0:x; select from r
} each `$f[`:C:/q/BitCoin/Input]
I hope this helps.
Many thanks,

I am currently using SQL Server 2008R2.
I am using this script:
SELECT a.productname, a.orderdate, a.workarea
FROM database1table1 AS a
WHERE a.orderdate >='2016/08/01'
Which gives the output:
PRODUCT NAME ORDER DATE WORKAREA
x 2016/08/07 NULL
y 2016/08/09 HOLDING
z 2016/08/10 ACTION
a 2016/08/12 ACTION
My problem arises when I amend the above script to read,
...
WHERE a.orderdate >='2016/08/01'
**AND a.workarea NOT IN ('HOLDING')**
When I do this, not only does it remove 'HOLDING', but it also removes the NULL rows as well, which I definitely do not want.
Please can you suggest an amendment to the script to prevent the NULLS being removed - I only want to see the value 'HOLDING' taken out.
With many thanks!
You can try a workaround
AND ISNULL(a.workarea,'') NOT IN ('HOLDING')
It will transform all null a.workarea in the "where" the "not in" works correctly
I'm trying to analyze how postgreSQL parse a query, and after some postgreSQL source code tracing with embedding printf() here and there, I've known that the query will be parsed into raw parse tree with raw_parser, which located in file parser.c.
The strange thing is, I've already embedded a printf() dummy in the raw_parser, and after re-installing the postgreSQL and execute a query, my printf() dummy is not printed to the screen!
Can anybody please help me, where I went wrong?
Thanks in advance :D
if you use printf(stderr, "...."), then you can find result in server log. Don't forget - you are not work with server directly. For debugging purposes there are a elog function - it's like printf for client application:
elog(NOTICE, "some text");
a format string is same like printf's format - but you must to remember, PostgreSQL uses a different formats than glibc - so you can to show only integer or float variables. String variables uses different format than is C zero finished string.
