I use method findAllRolesById for select data from table with param id=2.
When printing the results of the method findAllRolesById, I see an incorrect selection for me that I would like to see
I expected to see this result:
Because my table contains the following data:

A question concerning Azure Data Factory.
I need to persist the iterator value from a lookup activity (an Id column from a sql table) to my sink together with other values.
How to do that?
I thought that I could just reference the iterator value as #{item().id} as source and a destination column name from from my sql table sink. That doesn’t seems to work. The resulting value in the destination column is NULL.
I have used 2 look up activities, one for id values and the other for remaining values. Now, to combine and insert these values to sink table, I have used the following:
The ids look up activity output is as following:
I have one more column to combine with above id values. The following is the look up output for that:
I have given the following dynamic content as the items value in for each as following:
#range(0,length(activity('ids').output.value))
Inside for each activity, I have given the following script activity query to insert data as required into sink table:
insert into t1 values(#{activity('ids').output.value[item()].id},'#{activity('remaining rows').output.value[item()].gname}')
The data would be inserted successfully and the following is the reference image of the same:
I am not new to ETL and trying to become familiar with Talend. I cannot seem to get any output of a stored procedure (using tMSSqlSP) or a query (using tMSSqlRow). NOTE: Things I read indicated that tMSSqlRow doesn't produce columnar output but not sure that is correct.
The job shown below runs but no output comes from the tMSSqlSP component. The trace debug shows that the output title is null. However, manual execution of the SP in SSMS succeeds, showing both objid and title.
The SP performs a simple query accepting a single input parameter (int) and outputs two columns -- the objid (int) and the title (string):
create procedure st_sp_case_title_get
#objid int
as
select [objid], [title] from [dbo].[table_case] where [objid] = #objid
You need to use tParseRecordSet in order to retrieve and parse result sets from tMSSqlRow and tMSSqlSP :
Define a column to be your result set (mine is called result) of type Object, in addition to your input columns (my input param is personid). In tMSSqlSP parameters tab, set personid as type IN, and result to be of type RECORD SET.
tParseRecordSet schema :
It parses the result column and gets Firstname and Lastname columns (your objid, and title columns)
tMSSqlRow is very similar. Check my previous answer here for an example.
I have to do a select from a table and insert into another identical(same structure) table on two different DB connections.
This is my code:
from("direct:" + getId)
.toD("sql:classpath:" +getSql1 + "?datasource= DataSourse1&usePlaceHolder=true"))
.setHeaders("Results", simple(${body})
toD("sql:classpath:" +getSql2 + "?datasource= DataSourse2&usePlaceHolder=true"))
where
getSQL1 : Select * FROM Product1
and
getSQL2 :Insert Into Product2 Values(${headers.results})
It does not work because of the data format I'm trying to insert, I suppose. What I get from the Select is something like this:
[{ID=130, DESCRIPTION=Product130}]
So, I need to clean my data and get only 130, 'Product130'
Any help? Thanks.
Assuming your actual code works and you're just transferring one record, change the getSql1 select option part to this:
"?datasource= DataSourse1&usePlaceHolder=true&outputType=SelectOne"
That puts a map into your message body as a result, instead of List of Map. No need to copy the result into a header. With Camel's SQL component, it will look for named query parameters in your message body if the body type is a Java Map.
Next change your insert to use the parameters within the Map:
insert into Product2 (ID, DESCRIPTION) values (:#ID, :#DESCRIPTION)
Notice I included the column names. This is for safety and good practice. If by chance the column order isn't the same as the origin table, this will still work.
When i have the follow query:
str(db(db.items.id==int(row)).select(db.items.imageName)) + "\n"
The output includes the field name:
items.imageName
homegear\homegear.jpg
How do i remove it so that field name will not be included and just the selected imagename.
i tried referencing it like a list [1] gives me an out of range error and [0] i end up with:
<Row {'imageName': 'homegear\\homegear.jpg'}>
The above is not a list, what object is that and how can i reference on it?
Thanks!

db(db.items.id==int(row)).select(db.items.imageName) returns a Rows object, and its __str__ method converts it to CSV output, which is what you are seeing.
A Rows object contains Row objects, and a Row object contains field values. To access an individual field value, you must first index the Rows object to extract the Row, and then get the individual field value as an attribute of the Row. So, in this case, it would be:
db(db.items.id==int(row)).select(db.items.imageName)[0].imageName
or:
db(db.items.id==int(row)).select(db.items.imageName).first().imageName
The advantage of rows.first() over rows[0] is that the former returns None in case there are no rows, whereas the latter will generate an exception (this doesn't help in the above case, because the subsequent attempt to access the .imageName attribute would raise an exception in either case if there were no rows).
Note, even when the select returns just a single row with a single field, you still have to explicitly extract the row and the field value as above.
I am having a PostgreSQL function:
func(timestamp,timestamp,Integer[],varchar[])
I want to design a JasperReports report to fetch data from the function. For this, I created parameter of type list to take input from user and pass it as varchar array.
For this, I am trying to use the following query:
select * from func($P{interval_start}::timestamp,$P{interval_end}::timestamp,array[$P!{idParameter}],array[$P!{usersParameter}])
But when I am running the report, it gives error like column user1(passed from parameter) does not exist.
I also tried:
select * from func($P{interval_start}::timestamp,$P{interval_end}::timestamp,array[$P!{idParameter}],array[$P{usersParameter}])
But it says:

Please suggest, how to pass string array to PostgreSQL function from iReport?
