How to use a list of strings as a parameter of data service

Hello.

I need to create a service that receives a list of string as parameter. I read the thread list of values as param - is possible to bring down the query? but I was unable to make it work.

In the my namespace, I defined an element:

< xs: element name = "keyList" >
< xs:simpleType >
< xs:list itemType = "XS: String" / >
< / xs:simpleType >
< / xs: element >

In my dataservice, I stated the following function:

declare function tns:list ($keyList as element (bt: keyList)) as {element(bt:employee) *}

for $key in $keyList
for $employee in emp:EMPLOYEES()
where (fn:upper - eq fn:upper-case(fn:string($key))) case($employee/STR_KEY)
return
< bt: employee >
< bt: name > {fn:data($employee/STR_NAME)} < / bt: name >}
< / bt: employee >
};

When I test this situation, the generated SQL code considers that all the keys as the only parameter:
(...)
WHERE (UPPER (t1." STR_NAME") =?)
(...)

So, if I try a string of a list, it works:
(...)
WHERE (UPPER (t1." THE STR_NAME") ="STRING1")
(...)

But with two or more strings...
(...)
WHERE (UPPER (t1." THE STR_NAME") ="WORD1 WORD2")
(...)

What I am doing wrong?

Also, on the wire, I mentioned, I would like to know how I could make the reference "for $paramString in $paramStrings / AN_ELEMENT ' using my code.

Best regards and thanks for your time!

My answer in list of values as param - is possible to bring down the query? has been

I think you want:

for $paramString in $paramStrings / AN_ELEMENT

and you have:

for $key in $keyList

$keyList is a single element that contains a complete list, so $key is the only element that contains a complete list. And that is why it does not work for you.

Yourself and the other poster are doing more complicated things they should be. You can simply use the following (you need not specify a child of $keyList here). The ' * ' after XS: String means minOccurs = 0 maxOccurs = unlimited.

declare function tns:list($keyList_as_xs:string*)...

for $key in $keyList
...

  • How to use a list in a query so that you can sort the list according to an attached table?

    1. my initial query returns the phone numbers with inconsistent structures. Example:

    -555 (555) - 5678

    666-555-5678.

    555.5678 (444)

    1-888-555-5678

    2. I have to loop through the list and perform a certain number of cleaning functions, this is why the list looks like this:

    555-555-5678.

    666-555-5678.

    444-555-5678.

    888-555-5678.

    3. now, I need to use this list in a query, if I can use the first three digits to seek a regional indicative table sign and its link and be able to sort by area code. The indicative table looks like this:

    ThreeDigitCode AreaID

    555                         1

    666                         2

    444                         1

    888                         4

    I need to put the phone in the query list, so I can do a search of the areaID and the comparable information to a table that says AreaID 1 is Eastern and his sort-position is 1, etc..

    Thanks in advance for your advice.

    You can add an empty your query column, when you select the phone

    numbers and use this column to store the ThreeDigitCode:

    SELECT phone_number, '' as threeDigitCode FROM #your_table#

    then clean up the numbers and place the 3 digits in others

    column. And then using query of query to join phone numbers with

    area codes:

    
  



  SELECT *
  FROM phone_number
    INNER JOIN area_codes ON area_codes.threeDigitCode =
phone_number.threeDigitCode

  • Re: how to use &lt; af:validateLongRange &gt; to string

    Hi all

    I use Jdev11.1.2.3.0

    I have a field as a description of the type.i chain validation for this field set to enter characters 0-20 more than this by using < af:validateLongRange >

    < af:validateLongRange
    minimum = "1" messageDetailMinimum = "Please enter valid values" hintMinimum = "Please enter valid values" / >

    < maximum af:validateLength = "20" / >

    Here I can only record the numeric values up to 20. but I'm not able to store strings (letters) when I'm in the string values is to show the error as I said in the messageDetailMinimum.so how come off this.can any one help me please...

    Thank you

    G.Shilpa.

    This, I do not understand. You want to limit the entry for max 20 characters independently which characters. That's what the maximumLength property = "20" is for. There is no need in this case validation. However, if you must have a validation, you can use a regular expression as validator

    autoSubmit = "true" >

    messageDetailNoMatch = 'Length violation' / >

  • How to use % symbol for parameters in conditions in Discoverer

    Hi all

    In fact, I have to add four settings in that
    two param should be % (average for select all) as a default.

    That is to say that we use LIKE '%' in the query.

    the problem is when I enter a value for a parameter, it should train for this value,
    and if I need anything, I should enter the "%" symbol,

    so, for what Iam confused how to use this,

    Although I tried with a few options, it receives satisfactory results.

    someone will help me please to achieve this.

    Thank you in advance

    Published by: user10271105 on Sep 17, 2008 03:37

    Hello

    You can create a parameter and give % as default. If you set the condition to use AS and when the default is used for the parameter, then the query contains LIKE '%' and everything is selected.

    If you are using a list of values with your parameter, then you must add the '%' to your list of values so that the user can select this value.

    However, this method will not work if some values in your database contains characters of percentage, because the condition LIKE 'ABC DEF %' will return as well as ABC % DEF ABCXYZDEF.

    Unfortunately like escape syntax is not available in discoverer, so you have to invent a value that the user can enter for all, for example ALL the default value for the parameter.

    Then use a similar State to:

    question LIKE: param OR item = DECODE (: param,'* ALL *', item)
