SELECT documents.abc FROM documents WHERE documents.def IN ""
Here's a sample code and double quote means the binding parameter. Parameter is the keyword from user's search work.
Currently, if user doesn't put any keyword, this code doesn't return any result either.
I want to select all documents.abc if parameter is null or empty.
Can you help this out?
Did you mean this?
SELECT documents.abc FROM documents WHERE $param IS NULL OR $param = '' OR documents.def IN ($param)

I wanted to pass a parameterized query in ado.net source and i rea don this post that only way to do this is to use expressions.
So here is my expression
"SELECT
LEDGER_YR_MO,
LOCATION,
FDR_FND_NO,
FDR_INVST_POOL_CD,
FISCAL_YR_BEG,
FISCAL_YR_END,
POST_DATE,
FDR_FND_TTL,
FDR_FND_TYPE_CD,
FDR_FND_PURP_CD,
FDR_CR_ELIG_FL,
FDR_ANN_CR_RATE,
FDR_MTH_CR_RATE,
FDR_CR_AMT,
FDR_TR_ELIG_FL,
FDR_ANN_TR_RATE,
FDR_MTH_TR_RATE,
FDR_60MTH_AVG_SHARE_PRC,
FDR_TR_AMT,
FDR_PROJ_GEP_INCM_AMT,
FDR_TR_AUGMENTATION_AMT,
FDR_GEP_NET_PAYOUT_AMT
FROM
FS0TST.UCOP_FDR_TR_CR where
LEDGER_YR_MO = '"+ (DT_WSTR,30) #[User::END_LEDGER_YR] +"' "
but when I click evaluate the expression , I see blank instead of variable ..does anyone know the possible issue:
Here is the evaluate expression looks like
SELECT
LEDGER_YR_MO,
LOCATION,
FDR_FND_NO,
FDR_INVST_POOL_CD,
FISCAL_YR_BEG,
FISCAL_YR_END,
POST_DATE,
FDR_FND_TTL,

FDR_ANN_CR_RATE,
FDR_MTH_CR_RATE,
FDR_CR_AMT,
FDR_TR_ELIG_FL,
FDR_ANN_TR_RATE,
FDR_MTH_TR_RATE,
FDR_60MTH_AVG_SHARE_PRC,
FDR_TR_AMT,
FDR_PROJ_GEP_INCM_AMT,
FDR_TR_AUGMENTATION_AMT,
FDR_GEP_NET_PAYOUT_AMT
FROM
FS0TST.UCOP_FDR_TR_CR where
LEDGER_YR_MO = ''
When you click the Evaluate Expression button, no code actually gets executed, so the only thing SSIS can look at is the static default value you gave your variable.
If you want to see a value instead of a blank in the Evaluate Expression, you have to give your variable a default value, even if you don't intend to use that value. When the SSIS package is executed, whatever code you use to populate the variable will overwrite the default value, so having a default value is harmless.
Helo. Today is my another fight day with OLAP raport with optional parameter. I have problem with MDX query. I wrote it like this:
select
NON EMPTY {{[Measures].[VALUE]}} ON COLUMNS,
NON EMPTY {
IIF(ISEMPTY([CUSTOMER].[${param}]) //CHECKING IF PARAMETER IS EMPTY
,{[CUSTOMER].[COUNTRY].Members},
{[CUSTOMER].[${param}]}
)
}ON ROWS
from [TRANSACTIONS]
${param} is my optional parameter for [CUSTOMER].[COUNTRY]. I unchecked "required" check button for my parameter, so OLAP should have all [VALUE] after executing it without parameter. And there is a problem, because after launching my OLAP raport parameter probably wants to be filled with something. It gives me an error.
Profile attribute 'param' not existing.
But I dont want to fill it with profile attribute. I have created list of values, and analytical driver for my parameter, which I use to pass possible values to my list box string parameter - ${param}.
Is there possibility to have OLAP report with optional parameter? Any BI master here?
I would be greatfull for any help.
Update: I have done something like this, I think this syntax is right, (I was checking SpagoBI examples)
WITH MEMBER [CUSTOMER].[SELECTED] AS ' Parameter("param") ' , SOLVE_ORDER = 2
MEMBER [CUSTOMER].[LEN] AS ' LEN(Parameter("param")) ', SOLVE_ORDER = 1
select
NON EMPTY {{[Measures].[VALUE]}} ON COLUMNS,
NON EMPTY {
IIF([CUSTOMER].[LEN]=0
,{[CUSTOMER].[COUNTRY].Members},
{[CUSTOMER].[CUSTOMER].[SELECTED]}
)
}ON ROWS
from [TRANSACTIONS]
But now I have same error for both possibilities (set/unset) parameter
javax.servlet.jsp.JspException: org.apache.jasper.JasperException: javax.servlet.ServletException: javax.servlet.jsp.JspException: com.tonbeller.jpivot.olap.model.OlapException: 1
Any ideas? Thanks :)
This question is a direct copy oF your previous posts:
https://stackoverflow.com/questions/38970610/olap-report-with-optional-parameter
Is ${param} is a string?
If it is a string then the following should function:
WITH MEMBER [Measures].[x] AS ${param}
SELECT
NON EMPTY {[Measures].[x]} ON COLUMNS
FROM [TRANSACTIONS];
Does it function?
If it does not function then the question is not really mdx related - as for some reason your syntax or the way the parameter is moving to the client is wrong.
note
The above is the equivalent of this super simple script:
WITH
MEMBER [Measures].[x] AS "hello world"
SELECT
NON EMPTY
{[Measures].[x]} ON 0
FROM [Adventure Works];
Do you have AdvWrks cube? Try these:
WITH
MEMBER [Measures].[x] AS "I'm not empty"
SELECT
{
IIF
(
(IsEmpty([Measures].[x])) //<< this returns False
,[Product].[Product Categories].[Category].MEMBERS
,{[Measures].[x]} //<< this is what IIF returns
)
} ON 0
FROM [Adventure Works];
It returns this:
Now I tested out IsEmpty:
WITH
MEMBER [Measures].[x] AS "I'm not empty"
SELECT
{
IIF
(
(NOT //<< added this to check functionality of IsEmpty
IsEmpty([Measures].[x]))
,[Product].[Product Categories].[Category].MEMBERS //<< this is what IIF returns
,{[Measures].[x]}
)
} ON 0
FROM [Adventure Works];
We get the following:
What I think is happening in your scenario is this - the param is not empty but is actually a zero length string:
WITH
MEMBER [Measures].[x] AS ""
SELECT
{
IIF
(
(
IsEmpty([Measures].[x]))
,[Product].[Product Categories].[Category].MEMBERS
,{[Measures].[x]} //<< the zero length string goes to here
)
} ON 0
FROM [Adventure Works];
Results in:
mySQL NOOB question:
Table has a column = AgeGroup. It is populated with the following data options: U40, 40-44, 45-49, 50-54, 55-59, 60+.
I have a form which allows the user to select the 'Gender' and 'AgeGroup' they wish to view. This then uses a "WHERE" clause of "SELECT" SQL query. It uses in the following format:
FROM
#__test1
WHERE
EventName = '2011EoSummer' AND
Gender = {$REQUEST:Gender};
if(isset($_REQUEST['Age'])) AND AgeGroup = {$_REQUEST['Age']}
In the form, there is a option to get all ages via "Overall" but there is no data called "Overall" in the AgeGroup column. Overall should default to ALL age groups, but I don't know how this would read in the SQL query.
Example 1 URL: /&Gender=Men&AgeGroup=U40 => would display data in 'U40' 'Men'
Example 2 URL: /&Gender=Men&Age=Overall => would display ALL Age data
If I'm reading this right, when you have "overall" selected you want to return all the age groups (so as not to limit by any age group)?
If so you need to remove the AgeGroup clause in your SQL statment.
<?PHP
$sql = "SELECT * FROM tbl WHERE Gender = {$_REQUEST['gender']}";
if(isset($_REQUEST['age']))
{
$sql.= " AND AgeGroup = {$_REQUEST['age']}"
}
?>
This will default to overall, so you may want to change the logic appropriately, hope I got what you were after, if not ignore it!
Also as a side note $_REQUEST isn't the best to use, if your using a form as your action collector set it to post and use $_POST instead, if you cant use $_GET to pull your data out of the url instead of request.
Edit: Added in brackets to make it easier to read.
My situation is
I have a parameter, this is a list, allowing multi values. That mean the first record in the list is 'Select All'
When user select All I need to include in my report all records that match with the list plus those that are blank. (My dataset is returning these)
When user select only 1 or a few I want to include only these records. No those that are blank
My problem:
I have a filter in my dataset that evaluate a parameter in a list, but I need to add a conditional filter to include a blank records when the selection will be "Select All"
I tried to use expression but this doesn't work
Filter expression
Fields!NAME.Value in = Parameters!List.Value !!!!!!!!!!!! Work Fine
But I need to change it like as
If Parameters!List.Value = 'Select All' Then
Fields!NAME.Value in = Parameters!List.Value or Fields!NAME.Value = " "
Else
Fields!NAME.Value in = Parameters!List.Value
End
Can you give an advice who can I resolve it please !!!
I'm working in SSRS R2
Thanks!!
This worked for me
Expression: =IIF(Parameters!pLocation.Value <> " All Locations", Fields!LOCATION.Value, FALSE)
Operator: =
Value: =IIF(Parameters!pLocation.Value <> " All Locations", Parameters!pLocation.Value, FALSE)
If you use Filter on your Dataset, try this:
Expression: [NAME]
Operator: IN
Value (fx): =Split(Replace(Join(Parameters!List.Value, ","), "Select All", " "), ",")
Try to work along this path. Basically you can reconstruct the multi value items into a string with Join(), and deconstruct it again into array by using Split(); where in between, you can manipulate them, for modifying (e.g. converting "Select All" into " "), adding (imitating "OR"), or removing extra items.
There is an alternative for this.
Add one more item to the paramater dataset values say "Not Available" as Label and value with the null. then there will be no change in the stored procedure and you can retrieve the data.
If the user select the specific item then he will get those values only. If he selects all then he will get the data for the null also with the all the others.
Hope this will help
You can put the logic in just one location if you do it this way.
You filter on the parameter, unless it's all values then the filter always matches.
Just a little cleaner.
Expression: =IIF(Parameters!pLocation.Value <> " All Locations", Fields!LOCATION.Value, " All Locations")
Operator: =
Value: =Parameters!pLocation.Value
User Form Input - City
User Form Input - Venue
User Form Input - Cover
User Form Input - Time
User Form Input - Date
User Form Input - Number1
User Form Input - Number2
(if any are blank they are coverted to '*' on the way in. But could be whatever works.)
my $grabgig = $hookup->prepare(qq{SELECT `VenueNumber`,`Venue`,`CoverCharge`,`SetLength`,`City`,`Owner`,`Date`,`Time`,`Image1`,`Number`
FROM `gigs`
WHERE VenueNumber > ? AND `City` = ? AND `Venue` = ? AND `CoverCharge` = ?
AND Date = ? AND `Number` > ? AND `Number` < ?
AND `Time` LIKE ? LIMIT ?,?});
##########################################
$grabgig->execute('100',$city,$venue,$cover,'*',$number1,$number2,?,'0','6')
or die "Did not execute";
That is a basic example above.
I want to be able to return results based on the City Input.
If more input is present, then narrow down results accordingly.
But the query returns nothing if fields are empty (*).
I tried wildcards and so on then, I experimented with LIKE and NOT LIKE.
This seemingly simple search is driving me nuts.
Can someone help this newbie?
OK, I'm pretty unsure what you mean, BUT, my best undererstanding of what you're trying to do is to query like you do now BUT if a particular field is not populated in the form, to avoid adding that field to the where clause; as opposed to current query which instead does and myField="*".
Correct?
If that's so, you need to build your query, and replacement list, in pieces:
my $sql = qq{SELECT MY_FIELD_LIST_TOO_LAZY_TO_TYPE FROM `gigs` WHERE 2=2};
my #replacement_values = (); # These go into execute() instead of "?"s
if ($city ne "*") {
$sql .= qq[AND city = ?];
push #replacement_values, $city;
}
if ($number1 ne "*") {
$sql .= qq[AND number > ?];
push #replacement_values, $number1;
}
# ... more values processed the same way
my $grabgig = $hookup->prepare($sql);
$grabgig->execute(#replacement_values) or die "Did not execute";
If you want to do it more intelligently (i.e. to generalize), you will have the form fields in a hash; have a config hash mapping the form field name to the DB column name and the operator, and instead do the above as:
my %fields = (
city => ["city" , "="]
,number1 => ["number", ">"]
,number2 => ["number", "<"]
);
my $sql = qq{SELECT MY_FIELD_LIST_TOO_LAZY_TO_TYPE FROM `gigs` WHERE 2=2};
my #replacement_values = (); # These go into execute() instead of "?"s
foreach my $field (keys %form_data) {
next unless exists $fields{$field};
if ($form_data{$field} ne "*") {
$sql .= qq[ AND $fields{$field}->[0] $fields{$field}->[1] ?];
push #replacement_values, $form_data{$field};
}
}
my $grabgig = $hookup->prepare($sql);
$grabgig->execute(#replacement_values) or die "Did not execute";
I am assuming that you want to construct a query where only a few input parameters have valid values and the rest are undefined. If that is indeed what you want, here is what you could do: Construct the query dynamically. Here are the steps you could take assuming you are using CGI.pm and assuming that the where clause is just a series of "this = that" - In your case you have different operators - but the idea is the same.
First construct a "where" string from the CGI query parameter (Sorry untested code):
my $qrystr = '';
foreach ($query->param) {
if (my $val = $query->param($_)) {
$qrystr .= "where $_ = " . $dbh->quote($val) . ' and ';
}
}
$qrystr .= "where 1 = 1";
Now you can just prepare and execute the query : "select * from table $qrystr"
If you want automatic quoting you will have to use bind parameters which is an easy extension of the code above
Update There was a missing "where" in the last true clause "1 = 1" - Sorry, added it now
Sorry, the formatting bar was not appearing so, I rebooted. Now I cannot edit my question or comment.
What I am trying to do is provide a search for the users.
They select a city from a dropdown then some optional data can be entered / selected to narrow the results.
The optional data May or May Not be present in the table, could be a blank field.
I would like the results to show based on the selected criteria of the search in that City.
So, WHERE selected "input city" = "tables city column" look for the other options (ignore that particular criteria if field is empty) and return any matches that exist for that city.
I am then pushing into array in a While for output display.
I guess it would be like a car query. Select make where doors = 2 and color = red and engine = hamsterwheel but, the color field may be empty in the database..
