I am working on a Jasper report using iReport 5.6 and IBM DB2 as data source. I am passing a list of strings as a parameter to the report and that is where the problem rises. The query is below;
SELECT customers.mobile_number,
COALESCE(Count(DISTINCT transaction_entries.transaction_id), 0) AS
number_of_transactions,
COALESCE(Sum(Abs(transaction_entries.amount)) / 100, 0) AS
volume_of_transactions
FROM transaction_entries
JOIN customers
ON customers.id = transaction_entries.customer_id
WHERE transaction_entries.transaction_type = 'Seasonal'
AND transaction_entries.notification_text <> 'Notification'
AND customers.mobile_number IN ( $p ! {listOfMobileNumbers} )
GROUP BY customers.mobile_number
When I try to generate the report I get the error Caused by: com.ibm.db2.jcc.am.SqlDataException: DB2 SQL Error: SQLCODE=-420, SQLSTATE=22018, SQLERRMC=DECFLOAT, DRIVER=3.66.46.
Any idea why ? and the possible solution ?
I would first verify that by commenting-out the last predicate of the WHERE clause avoids the error; i.e. redact the failing statement such that the IN predicate referencing the Jasper variable as input is no longer part of the query.
Then, determine what defines that variable replacement, from the output of the following query:
select '$p ! {listOfMobileNumbers}' from sysibm.sysdummy1
If the effect of the above query, used to reveal the data in that list, presents something like '1234,567,890', then I would suggest modifying the data that defines that list to reflect either of '1234','567','890' or 1234, 567, 890 instead.
FWiW: IMO the actual DDL [for column(s) or the TABLE] is much clearer to a reader than suggesting merely that:
The mobile_number field is returned from the database as a String and not a DECIMAL

I'm trying to add named parameters to a dataset query in a SSRS report (I'm using Report Builder), but I have had no luck discovering the correct syntax. I have tried #parameter, $1, $parameter and others, all without success. I suspect the syntax is just different for PostgreSQL versus normal SQL.
The only success I have had with passing parameters was based on this answer.
It involves using ? for every single parameter.
My query might look something like this:
SELECT address, code, remarks FROM table_1 WHERE date BETWEEN ? AND ? AND apt_num IS NULL AND ADDRESS = ?
This does work, but in the case of a query where I pass the same parameter to more than one part of the SELECT statement, I have to add the same parameter to the list multiple times as shown here. They are passed in this order, so adding a new parameter to an existing query results in having to reshuffle, and sometimes completely rebuild, the query parameters tab.
What are the proper syntax and naming requirements for adding named Parameters when using a PostgreSQL data source in SSRS?
From my comment, this is what it would look like with a regular join:
with inparms as (
select ? as from_date, ? as to_date, ? as address
)
select t.address, t.code, t.remarks
from inparms i
join table_1 t
on t.date between i.from_date and i.to_date
and t.apt_num is null
and t.address = i.address;
I said cross join in my comment because it is sometimes quicker when retrofitting somebody else's SQL instead of trying to untangle things (thinking of a friend who uses right join sometimes just to ruin my day).
Basically I want to retrieve rows of data that meet my clause conditions using Power Query.
I got 400 rows of lookup values in my spreadsheet.
Each row represent 1 lookup code for example, code AAA1, AAB2 and so on
So lets say I have a select statement and I want to construct the where clauses using the above codes so my end sql statement will look like
select * from MyTable where Conditions in ('AA1', 'AAB2')
so so far I have this
let
Source = Excel.CurrentWorkbook(){[Name="Table5"]}[Content],
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Form ID",
Int64.Type}}),
test = Sql.Database("myserver", "myDB", [Query="SELECT * FROM myTable where" & #"Changed Type" & "])"
in
test
Obviously that didnt work but thats my pseduo scenario anyway.
Please could you advice what to do?
Thank you

I would create a "lookup" Power Query based on the Excel table. I would set the "Load To" properties to "Only Create Connection".
Then I would start the main Query by connecting to the SQL server using the Navigator to select "MyTable". Then I would add a Merge step to the main Query, to join to the "lookup" Query, matching the "Conditions" column to the "lookup" code. I would set the Join Type to "Inner". The Merge properties window will show you visually if the 2 columns you select actually contain matching data.
This approach does not require any coding, and is easier to build, extend and maintain.
Mike Honey's join is best for your problem, but here's a more general solution if you find yourself needing other logic in your where clause.
Normally Power query only generates row filters on an equality expression, but you can put any code you want in a Table.SelectRows filter, like each List.Contains({"AA1", "AAB2"}, [Conditions])
So for your table, your query would look something like:
let
Source = Excel.CurrentWorkbook(){[Name="Table5"]}[Content],
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Form ID", Int64.Type}}),
test = Sql.Database("myserver", "myDB"),
yourTable = test{[Name="myTable"]}[Data],
filtered = Table.SelectRows(yourTable, each List.Contains(#"Changed Type"[Form ID], [Conditions]))
in
filtered
The main downside to using the library functions is that Table.SelectRows only knows how to generate SQL where clauses for specific expression patterns, so the row filter probably runs on your machine after downloading the whole table, instead of having the Sql Server run the filter.
I am trying to determine a solution to filter records using LIKE with a multi-valued parameter. In a simplistic example a user wants to return a set of 5-digit Object codes by entering the following in a parameter window in a SSRS report:
#parm_Object
1,24,333,34567
This ideally would return Object codes satisfying the following criteria:
1 : All Object codes starting with '1'
24: All Object codes starting with '24'
333: Similar
34567: Object code '34567'
I guess a starting point for me would be to determine whether this could be handled in the actual query, or should I do it on the SSRS side.
general good practice is to get rid of the data you don't need ASAP. so that would be in the query.
a SSRS multivalued parameter will show up as a comma separated list in the query.
the first step is to get from this comma separated list to a table (or table function), then you can join this table and apply like operators
for example
SELECT *
FROM INFORMATION_SCHEMA.COLUMNS a
INNER JOIN dbo.split1('test,fafa,tata') b
ON 1=1
WHERE a.COLUMN_NAME like b.Value + '%'
will return rows having column names starting with test, fafa or tata. the dbo.split1 function you have to write your own or get one from the internet. the link suggested by Tab Alleman for example.
here is the code i execute...
dc.rs = dc.st.executeQuery("select count(*) from Accounts where date_join = CDATE(25-11-2012)");
It returns 0 rows even though I have 3 accounts in database that will match this.
The format i use when i insert date is
CDATE(day-month-year)
I tried also this format, but still returns nothing..
CDATE('25-November-2012')
I also use that format when i search using dates. But i can't understand why it returns no rows.
i get this error when I try to use the getDate(1) after I query that..
[Microsoft][ODBC Microsoft Access Driver]Restricted data type attribute violation on column number 1 (Expr1000)
Is there any wrong with my where clause?
Change the where clause to data_join = CDATE('25-11-2012')
I have a database that has two tables that need to be linked, but in one table the data is padded with zeros. For example, the tables may look like this:
CUSTOMER.CUSTNUM = 00000000123456
CUSTOMERPHONE.CUSTNUM = 123456
I can't figure out how to get these tables to properly join.
What I'm trying to do now is trick Crystal Reports into specifying the Join clause by adding the following to the selection expert:
Right ({CUSTOMER.CUSTNUM}) = {CUSTOMERPHONE.CUSTNUM}
That's not working though, and I get no records at all in my report.
Any ideas?
Crystal doesn't like heterogeneous joins.
Options:
use a command object, which will give you more control over the linkage
create a SQL Expression that performs the desired concatination; link fields in the record-selection formula
use a subreport for the linked table
alter the table to make the data types compatible
create a SQL view that performs the joins
First thing, why does CUSTOMER.CUSTNUM have leading zeros in the first place? It seems to me that it should be a NUMERIC data type instead of a VARCHAR. CUSTNUM should be consistent in all of the tables. Just a thought.
Anyway, to answer your question, you could try creating a SQL Command in Crystal to join the two tables. In the join, just use your database's function for converting from a varchar to a number. For example, in Access you could do:
SELECT *
FROM `Customer`
LEFT OUTER JOIN `Orders` ON `Orders`.`Numeric Customer ID` = CLng(`Customer`.`Varchar Customer ID`)
If fastest performance isn't an issue, you can accomplish this using Select Expert. I think the problem is your formula.
Try changing your formula from this:
{CUSTOMERPHONE.CUSTNUM} = Right({CUSTOMER.CUSTNUM})
to this:
{CUSTOMERPHONE.CUSTNUM} = Right({CUSTOMER.CUSTNUM}, Length({CUSTOMERPHONE.CUSTNUM}))
