How to use String Function Find() in a String Value Test?

Hi,
i intend to match a substring of the string returned from my UUT when using a String Value Test - VI call.
I write the returned string to a Local Variable type String (Locals.data_read) and in the Limits Tab - under Expected String Value am using Find(Locals.data_read, "Connected"). When i Check the expression for Errors - i get a warning "Expected String, found Number {64-bit Floating Point}. this value will cause a run-time error."
What am i missing?
Thanks
Kech
Solved!
Go to Solution.

The Find function evaluates to a number:
Number Find(String string, String stringToSearchFor, Number indexToSearchFrom = 0, Boolean ignoreCase = False, Boolean searchInReverse = False)
Returns: The zero-based character index, starting at the beginning of the string, of the first character in the substring.  The function returns -1 if it does not find the substring.
It looks to me like you need to do a numeric step type.  Not a string value test.
Or you can do something like this:
Find(Locals.data_read, "Connected") < 0 ? "Doesn't Matter What Is Here" : Locals.data_read
Hope this helps,

  • REGEXP_REPLACE: How to use a function over the found strings?

    Hello,
    Consider the following:
    select regexp_replace('A1BBCCA2BBCC', '(A.)', '[\1]')
    from dual
    '[A1]BBCC[A2]BBCC'Now I try to put a function on the replaced strings:
    select regexp_replace('A1BBCCA2BBCC', '(A.)', lower('[\1]'))
    from dual
    '[A1]BBCC[A2]BBCC'The result is the same i.e. the function lower has been executed with my reg. expression as a parameter, not the result strings. How can I execute the function passing as a parameter not the reg. expression but the strings, that have been found? (Of course, my real need is to use a custom function, not "lower").
    Thanks in advance.
    Best Regards,
    Beroetz

    I'm sure there must be a simpler way, but this is my first thought... (although strictly speaking in this example I could get rid of the lower function and just include 'a' hardcoded.)

  • How to use NODIM func with out it's values being rounded

    I created a new calculated key figure in Query Designer 3.x, and used the function NODIM() - Value with out dimensions. When I use this function, the values are rounding off to the nearest value.
    For example, I have a value 0.000075 US$, when I use NODIM function the value is displayed as 0.000080. Value is getting rounded to nearest value.
    I tried using absolute value it did not work.
    Can any one tell me how to use NODIM function with out it's value being rounded to nearest value.
    Thanks,

    Hi,
    According to your description, you might want that "Notice" field has a default value when form is created and users can be able to change the value of that
    field.
    As a workaround, you can add an action rule in “Name” field via InfoPath to fill the default value in “Notice” field only when “Name” field is not blank and “Notice”
    field is blank.
    Settings of the rule are as below, you can modify it based on your need:
    Here is a link about how to add an action rule in InfoPath form, you can use it as a reference:

  • How to use complex function as condition in Oracle Rule Decision Table?

    How to use complex function as condition in Oracle Rule Decision Table?
    We want to compare an incoming date range with the date defined in the rules. This date comparison is based on the input date in the fact & the date as defined for each rule. Can this be done in a decision table?

    I see a couple of problems here.
    First, what you posted below is not a syntactically valid query. It seems to be part of a larger query, specifically, this looks to be only the GROUP BY clause of a query.

As you discovered, if you attempt to do so, you'll find it doesn't work. If you stop and think about how SQL is processed, it should make sense to you why the SQL is not valid.
    If you want to apply a filter condition such as:
    trunc(max(RD.DATERECEIVED)) BETWEEN TO_DATE('01/08/2011','DD/MM/YYYY') AND TO_DATE('01/08/2011','DD/MM/YYYY')you should do it in a HAVING clause, not a where clause:

  • Use REGEXP_INSTR to find a text string with space(s) in it

    I am trying to use REGEXP_INSTR to find a text string with space(s) in it.
    (This is in a Function.)
    Let's say ParmIn_Look_For has a value of 'black dog'. I want to see if
    ParmIn_Search_This_String has 'black dog' anywhere in it. But it gives an error
    Syntax error on command line.
    If ParmIn_Look_For is just 'black' or 'dog' it works fine.
    Is there some way to put single quotes/double quotes around ParmIn_Look_For so this will
    look for 'black dog' ??
    Also: If I want to use the option of ignoring white space, is the last parm
    'ix' 'i,x' or what ?
    SELECT
    REGEXP_INSTR(ParmIn_Search_This_String,
    '('||ParmIn_Look_For||')+', 1, 1, 0, 'i')
    INTO Position_Found_In_String
    FROM DUAL;

  • How to use Aggregate Functions during Top N analysis?

    Say i want to find top 5 highest salaries and their totals and average. In that case how to use aggregate functions. Please give me an example on this.

    Message was edited by:
    user642387

    Hi,
    Yes, you can do that with aggregate functions.
    First, do a sub-query to retrieve all the salaries (in descending order), then say "WHERE ROWNUM <= 5" in the main query. Use the aggregate SUM and AVG functions in the main query.
    Analytic functions are easier to use for jobs like this, once you get familiar with them. If you're not leaving the field this month, then it's probably worthwhile for you to get familiar with analytic functions.

  • How to use Min function to get FileName into a Variable

    I was wondering how to use MIN function in Evaluate variable in package to get the first file name from the list(Datastore)
    With reference to Merging Flat Files into a single file Post number-4
    Thanx

    Hi Diwakar,
    That List data store should be table, than only it will gives the min of the filename string,
    If it is a file datastore, Min function does not works properly it will returns a first name in the file data store.
    so please, use an interface to upload the List filedatastore into some other temp table. From that table you can use variable to get Min value of file name.
    Thanks

    Hi Satish,
    You know, the real power of forums like these is the search functionality. First you locate the correct forum, you succeeded in that and then you locate the search field and type in your question. In your case "check function module"
    I suggest you do this right away and be amazed at all of the answers about his topic. Maybe you'll even find some topic about exactly the same issue with a different solution than check function modules and on top of that you learn something this way. Talk about win-win situation

  • Error using LISTAGG function to aggregate the strings.

    HI
    I am using LISTAGG function to aggregate the strings but throws a error ORA - 19011
    The output of the aggregated function exeeds the varchar limit.
    I dont know how to change it to a LOB.
    Can you please help me.
    This is the code.
    I have used both the functions.
    RTRIM(XMLAGG(XMLELEMENT(e,FDCT.USER_NAME || ' ')).extract('//text()'), ' ')

    LISTAGG(FDCT.USER_NAME, ',') WITHIN GROUP (ORDER BY FDCT.USER_NAME)
    Edited by: 787819 on Jun 22, 2011 1:46 PM

    If a function returns a VARCHAR2, then it will error (or sometimes truncate depending on function) when reaching the limit of the datatype.
    Perhaps an alternative would be to write your own user-defined aggregate function that works with a CLOB.

  • How to use standard function keys as custom keys

    how to use standard function keys as custom keys.
    i have encountered that problem while developing a screen, there i'm supposed to use standard function key F2 ( which actually meant for choose) for clearing the screen fields where the cursor is present and f1 for saving data that entered in screen fields, etc...
    kindly help me out.

    Hi ,
    Solution to use SAP reserve function keys F1 .. F4 (mostly this requirement comes up for RF screens) can be acheived by assigning your new Function code using the Menu path Utilities --> F key Consistency in the Menu Painter (SE41) . Once you assign your cutom function code to the standard Fn keys the only remaining step is to make sure that you set a curson on any of the field on sceen by using the Key Word "SET CURSOR" .
    If you dont use the key word SET CURSOR in the PBO of the screen then you might not see any response for F4.
    Thanks
