Returning array from BuildOp

[Grace J.]

Hi All, I have created a BuildOp stage which needs to return an array value. I need to return the value in date_out4 via the output interface outdata1. How can we return an array from BuildOp to datastage. What datatype we need to mention in datastage for date_out4? I tried like below,

APT_String date_out4[8];
oudata1.date_out4[1]=year1;
oudata1.date_out4[2]=month1;
oudata1.date_out4[3]=day1;

But it is giving error as follows... Please help

What are source lines 40-50, could you post those?

[Grace J.]

outdata1.date_out4[1]=year1;
outdata1.date_out4[2]=month1;
outdata1.date_out4[3]=day1;

[ArndW]

And how are these variables declared?

[Grace J.]

APT_String date_out4[8];
char year1,month1,day1;

[ArndW]

And how about "oudata1" or is it "outdata1"?

[Grace J.]

outdata1 only..

outdata1.date_out4[1]=year1;
outdata1.date_out4[2]=month1;
outdata1.date_out4[3]=day1;

[Sainath.Srinivasan]

Create a character string (say char tempStr[9] ) and store your result there.

Set the date_out4 from this value.

Thank You For Your Reply...I tried as follows...

[b]APT_String date_out4[8],temp[8];
temp[1]=year1;
temp[2]=month1;
temp[3]=day1;
outdata1.date_out4=temp;[/b]

I got the error as follows..

[b]And I tried as....[/b]

[b]APT_String date_out4[8],temp[8];
temp[1]=year1;
temp[2]=month1;
temp[3]=day1;
outdata1.date_out4[1]=temp[1];
outdata1.date_out4[2]=temp[2];
outdata1.date_out4[3]=temp[3];
writeRecord(0);[/b]

I got the error as...

Any idea of how to return an array value???

[Sainath.Srinivasan]

What I meant was to use a temporary char variable as below

Code: Select all

char tempStr[9]; // assuming 8 + 1 null

outdata1.date_str4 = tempStr; // direct setting without positional values

[Kryt0n]

APT_String date_out4[8];
oudata1.date_out4[1]=year1;
oudata1.date_out4[2]=month1;
oudata1.date_out4[3]=day1;

Never having tried a buildop I'm not sure what an APT_String is but guess a char pointer which then asks what are you trying to return, a set of dates or just one date?

If just one date, return just one string and strip it into day/month/year in DS (pretty much what Sainath has suggested).

If a set of dates, then you need to allocate space to the string for each date or assign date_out4 to the address of year1 etc (date_out4 looks to be a pointer, therefore it needs to look at an address not a value).

From what I can see, option 1 is what you are looking for.

(Of course, this is quite likely down to the fact I haven't done a buildop but why have you declared a date_out4 and then attempt to assign a value to oudata1.date_out4?)

[Sainath.Srinivasan]

Something I noticed after seeing Kryt0n's response....

You are declaring date_out4 but then attempt to set out_data1.date_out4.

They are two different variables.
