I have below query:
select 'my.MYNAME=' + name from hostnames;
my.MYNAME=abc
my.MYNAME=xyz
my.MYNAME=poi
The query is dynamic is gives3 result, it may give more result depending upon data.
I need following output:
my.MYNAME1=abc
my.MYNAME2=xyz
my.MYNAME3=poi
Numbers appending to MYNAME according to result it gives.
I have tried
select 'my.MYNAME={c}' + name from hostnames where (select count(*) as c from name);
but it is not working.
One way to go about it is:
SELECT CONCAT(CONCAT(CONCAT('my.MYNAME',ROWNUM),'='), name) FROM hostnames

When I search for the Dünyas word with a LIKE operator I can see the results but when I search Dünyası word with LIKE operator, it returns no results. Problem is not ı or ü letters I tried with i and u letters as well.
This query:
select * from DbDivx where NameTurkish like '%Dünyas%' =>
returns:
Boksörün Dünyası
Geleceğin Dünyası
Su Dünyası
However:
select * from DbDivx where NameTurkish like '%Dünyası%' =>
returns nothing.
Can you help me please?
http://sqlfiddle.com/#!6/8c359/1
create table test (someName nvarchar(300))
insert into test (someName)
select N'Boksörün Dünyası'
union all select N'Geleceğin Dünyası'
union all select N'Su Dünyası'
select * from test where someName like N'%Dünyası%'
Not having any issues with the above fiddle. Note that when i inserted data without the N in front of it, the like query did not return results.
hopefully this helps!
Is there an easy way to do URL decoding within the BigQuery query language? I'm working with a table that has a column containing URL-encoded strings in some values. For example:
http://xyz.com/example.php?url=http%3A%2F%2Fwww.example.com%2Fhello%3Fv%3D12345&foo=bar&abc=xyz
I extract the "url" parameter like so:
SELECT REGEXP_EXTRACT(column_name, "url=([^&]+)") as url
from [mydataset.mytable]
which gives me:
http%3A%2F%2Fwww.example.com%2Fhello%3Fv%3D12345
What I would like to do is something like:
SELECT URL_DECODE(REGEXP_EXTRACT(column_name, "url=([^&]+)")) as url
from [mydataset.mytable]
thereby returning:
http://www.example.com/hello?v=12345
I would like to avoid using multiple REGEXP_REPLACE() statements (replacing %20, %3A, etc...) if possible.
Ideas?
Below is built on top of #sigpwned answer, but slightly refactored and wrapped with SQL UDF (which has no limitation that JS UDF has so safe to use)
#standardSQL
CREATE TEMP FUNCTION URLDECODE(url STRING) AS ((
SELECT SAFE_CONVERT_BYTES_TO_STRING(
ARRAY_TO_STRING(ARRAY_AGG(
IF(STARTS_WITH(y, '%'), FROM_HEX(SUBSTR(y, 2)), CAST(y AS BYTES)) ORDER BY i
), b''))
FROM UNNEST(REGEXP_EXTRACT_ALL(url, r"%[0-9a-fA-F]{2}|[^%]+")) AS y WITH OFFSET AS i
));
SELECT
column_name,
URLDECODE(REGEXP_EXTRACT(column_name, "url=([^&]+)")) AS url
FROM `project.dataset.table`
can be tested with example from question as below
#standardSQL
CREATE TEMP FUNCTION URLDECODE(url STRING) AS ((
SELECT SAFE_CONVERT_BYTES_TO_STRING(
ARRAY_TO_STRING(ARRAY_AGG(
IF(STARTS_WITH(y, '%'), FROM_HEX(SUBSTR(y, 2)), CAST(y AS BYTES)) ORDER BY i
), b''))
FROM UNNEST(REGEXP_EXTRACT_ALL(url, r"%[0-9a-fA-F]{2}|[^%]+")) AS y WITH OFFSET AS i
));
WITH `project.dataset.table` AS (
SELECT 'http://example.com/example.php?url=http%3A%2F%2Fwww.example.com%2Fhello%3Fv%3D12345&foo=bar&abc=xyz' column_name
)
SELECT
URLDECODE(REGEXP_EXTRACT(column_name, "url=([^&]+)")) AS url,
column_name
FROM `project.dataset.table`
with result
Row url column_name
1 http://www.example.com/hello?v=12345 http://example.com/example.php?url=http%3A%2F%2Fwww.example.com%2Fhello%3Fv%3D12345&foo=bar&abc=xyz
Update with further quite optimized SQL UDF
CREATE TEMP FUNCTION URLDECODE(url STRING) AS ((
SELECT STRING_AGG(
IF(REGEXP_CONTAINS(y, r'^%[0-9a-fA-F]{2}'),
SAFE_CONVERT_BYTES_TO_STRING(FROM_HEX(REPLACE(y, '%', ''))), y), ''
ORDER BY i
)
FROM UNNEST(REGEXP_EXTRACT_ALL(url, r"%[0-9a-fA-F]{2}(?:%[0-9a-fA-F]{2})*|[^%]+")) y
WITH OFFSET AS i
));
It's a good feature request, but currently there is no built in BigQuery function that provides URL decoding.
One more workaround is using a user-defined function.
#standardSQL
CREATE TEMPORARY FUNCTION URL_DECODE(enc STRING)
RETURNS STRING
LANGUAGE js AS """
try {
return decodeURI(enc);;
} catch (e) { return null }
return null;
""";
SELECT ven_session,
URL_DECODE(REGEXP_EXTRACT(para,r'&kw=(\w|[^&]*)')) AS q
FROM raas_system.weblog_20170327
WHERE para like '%&kw=%'
LIMIT 10
I agree with everyone here that URLDECODE should be a native function. However, until that happens, it is possible to write a "native" URLDECODE:
SELECT id, SAFE_CONVERT_BYTES_TO_STRING(ARRAY_TO_STRING(ps, b'')) FROM (SELECT
id,
ARRAY_AGG(CASE
WHEN REGEXP_CONTAINS(y, r"^%") THEN FROM_HEX(SUBSTR(y, 2))
ELSE CAST(y AS bytes)
END ORDER BY i) AS ps
FROM (SELECT x AS id, REGEXP_EXTRACT_ALL(x, r"%[0-9a-fA-F]{2}|[^%]+") AS element FROM UNNEST(ARRAY['domodossola%e2%80%93locarno railway', 'gabu%c5%82t%c3%b3w']) AS x) AS x
CROSS JOIN UNNEST(x.element) AS y WITH OFFSET AS i GROUP BY id);
In this example, I've tried and tested the implementation with a couple of percent-encoded page names from Wikipedia as the input. It should work with your input, too.
Obviously, this is extremely unwieldly! For that reason, I'd suggest building a materialized join table, or wrapping this in a view, rather than using this expression "naked" in your query. However, it does appear to get the job done, and it doesn't hit the UDF limits.
EDIT: #MikhailBerylyant's post below has wrapped this cumbersome implementation into a nice, tidy little SQL UDF. That's a much better way to handle this!
I am trying to fire this query in MS Access
SELECT file_number,
IIF(invoice_type='Spent on Coding',SUM(CINT(invoice_amount)), 0) as CodingExpense
FROM invoice
GROUP BY file_number
I am getting this error
Error in list of function arguments: '=' not recognized. Unable to
parse query text.
I tried replacing IIF with SWITCH to no avail.
What's wrong with my query and how to correct this?
AFAIK, you need that round the other way:
Sum(IIF(invoice_type="Spent on Coding",CINT(invoice_amount), 0)) as CodingExpense
However, I would suggest:
Round(Sum(IIF(invoice_type="Spent on Coding",invoice_amount, 0)),0) as CodingExpense
I have a query and I would like to use an IIf function as part of the criteria. Here is the full SQL:
SELECT Hits.HitID, Hits.ListingID, Hits.HitCount, Hits.HitDate, Hits.HitTypeID, Hits.IsDeleted
FROM Hits
WHERE (((Hits.HitDate)>=[Forms]![frmReports]![txtStartDate]) AND ((Hits.IsDeleted)="N"));
Here is the piece of code that causing me anguish:
>=[Forms]![frmReports]![txtStartDate]
If I have a date on frmReports, this will work fine; however, if no date is entered, this returns 0 records (I want it to return ALL records, if this is the case).
How can I make this work?
Try this:
SELECT Hits.HitID, Hits.ListingID, Hits.HitCount, Hits.HitDate, Hits.HitTypeID, Hits.IsDeleted
FROM Hits
WHERE (((Hits.HitDate)>=nz([Forms]![frmReports]![txtStartDate],"1/1/1")) AND ((Hits.IsDeleted)="N"));
or this
SELECT Hits.HitID, Hits.ListingID, Hits.HitCount, Hits.HitDate, Hits.HitTypeID, Hits.IsDeleted
FROM Hits
WHERE (((Hits.HitDate)>=[Forms]![frmReports]![txtStartDate]) AND ((Hits.IsDeleted)="N"))
OR (([Forms]![frmReports]![txtStartDate] = "") AND (Hits.IsDeleted="N"));
