How to get the last value from the url in OIC?
https://test.com:111/fscm/resources/11.13.18.05/invoices/11111/child/invoiceInstallments/
00030000000SDSDD00057708000000000000CB2F0000000SDSC000577080
I want to get 00030000000SDSDD00057708000000000000CB2F0000000SDSC000577080 value from the url. Which is invoiceInstallmentUniqId. Can anyone help me with this?
Thank you!
A simple option is to use regular expression:
Sample data:
SQL> with test(col) as
2 (select 'https://test.com:111/fscm/resources/11.13.18.05/invoices/11111/child/invoiceInstallments/00030000000SDSDD00057708000000000000CB2F0000000SDSC000577080' from dual)
Query:
3 select regexp_substr(col, '\w+$') result
4 from test;
RESULT
------------------------------------------------------------
00030000000SDSDD00057708000000000000CB2F0000000SDSC000577080

I am trying to build bigquery stored procedure where I need to pass the table name as a parameter. My code is:
CREATE OR REPLACE PROCEDURE `MKT_DS.PXV2DWY_CREATE_PROPERTY_FEATURES` (table_name STRING)
BEGIN
----step 1
CREATE OR REPLACE TABLE `MKT_DS.PXV2DWY_CREATE_PROPERTY_FEATURES_01` AS
SELECT DISTINCT XX.HH_ID, A.ECR_PRTY_ID, XX.ANCHOR_DT
FROM table_name XX
LEFT JOIN
(
SELECT DISTINCT HH_ID, ECR_PRTY_ID
FROM `analytics-mkt-cleanroom.Master.EDW_ECR_ECR_MAPPING`
WHERE HH_ID NOT LIKE 'U%'
AND ECR_PRTY_ID IS NOT NULL
)A
ON XX.HH_ID = A.HH_ID----one (HH) to many (ecr)
;
END;
CALL MKT_DS.PXV2DWY_CREATE_PROPERTY_FEATURES(`analytics-mkt-cleanroom.MKT_DS.Home_Services_Multi_Class_Aesthetic_Baseline_Final_Training_Sample`);
I followed a couple of similar questions here and here, tried writing an EXECUTE IMMEDIATE version of the above but not able to work out the right syntax.
I think issue is; the SELECT statement in my code is selecting multiple columns XX.HH_ID, A.ECR_PRTY_ID, XX.ANCHOR_DT and the EXECUTIVE IMMEDIATE setup is meant to work only for one column. But I'm not sure. Please advise. Thank you.
I am basically trying to write stored procedures for data pipeline building.
Hope below is helpful.
pass a parameter as a string.
CALL MKT_DS.PXV2DWY_CREATE_PROPERTY_FEATURES(`analytics-mkt-cleanroom.MKT_DS.Home_Services_Multi_Class_Aesthetic_Baseline_Final_Training_Sample`);
-->
CALL MKT_DS.PXV2DWY_CREATE_PROPERTY_FEATURES('analytics-mkt-cleanroom.MKT_DS.Home_Services_Multi_Class_Aesthetic_Baseline_Final_Training_Sample');
use EXECUTE IMMEDIATE since a table name can't be parameterized as a variable in a query.
----step 1
EXECUTE IMMEDIATE FORMAT("""
CREATE OR REPLACE TABLE `MKT_DS.PXV2DWY_CREATE_PROPERTY_FEATURES_01` AS
SELECT DISTINCT XX.HH_ID, A.ECR_PRTY_ID, XX.ANCHOR_DT
FROM `%s` XX
LEFT JOIN
(
SELECT DISTINCT HH_ID, ECR_PRTY_ID
FROM `analytics-mkt-cleanroom.Master.EDW_ECR_ECR_MAPPING`
WHERE HH_ID NOT LIKE 'U%%'
AND ECR_PRTY_ID IS NOT NULL
)A
ON XX.HH_ID = A.HH_ID----one (HH) to many (ecr)
;
""", table_name);
escape % in a format string with additional %

-->

SELECT "Rental".*, "Rental".ora_rowscn as TimeStamp FROM "Rental"
inner join "UserBranch" on "UserBranch"."fkBranchId" = "Rental"."fkBranchId"
WHERE "Rental"."IsDeleted"='N' ;
This query returns me invalid identifier exception in oracle 10g. I'm a beginner and don't know why the exception is coming. please help. Thank you.
Select "Rental".* ,"UserBranch"."fkBranchId", "Rental".ora_rowscn as TimeStamp from "Rental","UserBranch"
where "UserBranch"."fkBranchId" = "Rental"."fkBranchId"
and "Rental"."IsDeleted"='N';
without joins it works perfectly for me
Please try to get your values with the below query :
SELECT Rental.*, Rental.ora_rowscn as TimeStamp FROM Rental
inner join UserBranch on UserBranch.fkBranchId = Rental.fkBranchId
WHERE Rental.IsDeleted='N' ;
I want to get the number of selected rows as well as the selected data. At the present I have to use two sql statements:
one is
select * from XXX where XXX;
the other is
select count(*) from XXX where XXX;
Can it be realised with a single sql string?
I've checked the source code of sqlite3, and I found the function of sqlite3_changes(). But the function is only useful when the database is changed (after insert, delete or update).
Can anyone help me with this problem? Thank you very much!
SQL can't mix single-row (counting) and multi-row results (selecting data from your tables). This is a common problem with returning huge amounts of data. Here are some tips how to handle this:
Read the first N rows and tell the user "more than N rows available". Not very precise but often good enough. If you keep the cursor open, you can fetch more data when the user hits the bottom of the view (Google Reader does this)
Instead of selecting the data directly, first copy it into a temporary table. The INSERT statement will return the number of rows copied. Later, you can use the data in the temporary table to display the data. You can add a "row number" to this temporary table to make paging more simple.
Fetch the data in a background thread. This allows the user to use your application while the data grid or table fills with more data.
try this way
select (select count() from XXX) as count, *
from XXX;
select (select COUNT(0)
from xxx t1
where t1.b <= t2.b
) as 'Row Number', b from xxx t2 ORDER BY b;
just try this.
You could combine them into a single statement:
select count(*), * from XXX where XXX
or
select count(*) as MYCOUNT, * from XXX where XXX
To get the number of unique titles, you need to pass the DISTINCT clause to the COUNT function as the following statement:
SELECT
COUNT(DISTINCT column_name)
FROM
'table_name';
Source: http://www.sqlitetutorial.net/sqlite-count-function/
For those who are still looking for another method, the more elegant one I found to get the total of row was to use a CTE.
this ensure that the count is only calculated once :
WITH cnt(total) as (SELECT COUNT(*) from xxx) select * from xxx,cnt
the only drawback is if a WHERE clause is needed, it should be applied in both main query and CTE query.
In the first comment, Alttag said that there is no issue to run 2 queries. I don't agree with that unless both are part of a unique transaction. If not, the source table can be altered between the 2 queries by any INSERT or DELETE from another thread/process. In such case, the count value might be wrong.
Once you already have the select * from XXX results, you can just find the array length in your program right?
If you use sqlite3_get_table instead of prepare/step/finalize you will get all the results at once in an array ("result table"), including the numbers and names of columns, and the number of rows. Then you should free the result with sqlite3_free_table
int rows_count = 0;
while (sqlite3_step(stmt) == SQLITE_ROW)
{
rows_count++;
}
// The rows_count is available for use
sqlite3_reset(stmt); // reset the stmt for use it again
while (sqlite3_step(stmt) == SQLITE_ROW)
{
// your code in the query result
}
I am using Postgresql9.2 and SQLAlchemy0.8 . I have a stored procedure in database which has many out parameters and i want them to use by dot notation. But so far I have failed miserably. Below is how my code looks like.
An example to show what i am doing is as follows.
CREATE OR REPLACE FUNCTION stored_proc_name(IN in_user_id bigint, IN in_amount bigint,
OUT pout_one bigint, OUT pout_two bigint )
RETURNS record AS
$BODY$
begin
select count(*) as AliasOne into pout_one from tabe_names where conditions;
select user_name as AliasTwo into pout_two from table_name where condition;
end;
$BODY$
LANGUAGE plpgsql VOLATILE
COST 100;
ALTER FUNCTION stored_proc_name(bigint, bigint)
OWNER TO postgres;
My code snippet is as following:
#session object from sessionmaker
result_obj = session.execute(func.stored_proc_name(user_id, amount))
print result_obj.fetechall()
#The above print statement prints following on the console.
>> [('(1,100)',)]
Clearly the above result fetches string. What I want is something like result_obj.pout_one and use it in my code.
Is there any way of achieving it. A working code snippet will be highly appreciated.
Thanks a lot!
You could try something like this:
query = select([column('pout_one'), column('pout_two')],
from_obj=[func.stored_proc_name(user_id, amount)])
session.execute(query)
The inspiration for this is from the SQLAlchemy list where someone asked a similar question. This could result in the desired output (I can't test it right now).
So I have an update statement:
UPDATE billing_infos set card_number = ''
FROM orders
WHERE billing_infos.order_id = orders.id ...);`
How would I find the count of how many records are updated by this statement?
I'm doing this in my console through ActiveRecord::Base.connection.execute() so it's just returning a <PG::Result:0x007f9c99ef0370> object.
Anyone know how I could do this using SQL or a Rails method?
p = ActiveRecord::Base.connection.execute(<query>)
p.cmd_status
This gives the command status. Something like
UPDATE 16
For more methods on PG::Result, refer here
While solution showed by Vimsha will definitely work, there is also another solution (assuming you use recent enough pg), which could be a bit nicer:
with u as (
update ... returning 1
)
select count(*) from u;
That's one query, and it's technically a select, so you run it as any other select.
As mentioned in a comment of another answer, the easiest way is to use the cmd_tuples attribute of the result
result = ActiveRecord::Base.connection.execute("insert into tbl select 'test' col")
puts result.cmd_tuples
result
1
