Is it possible to select distinct value in PXSelector in Acumatica 5.x?
[PXSelector(typeof(Search<TestTable.Value, Where<TestTable.ID, Equal<Current<CurTable.ID>>>>))]
Values in TestTable are free form and can be duplicate. I would like selector to be able to select without duplicate value.
ID Value
1 Test1
1 Test2
1 Test1
Desire Result should show only 'Test1' and 'Test2'.
I would think you could use Search4 and do an aggregate:
[PXSelector(typeof(Search4<TestTable, Where<TestTable.ID, Equal<Current<CurTable.ID>>>, Aggregate<GroupBy<TestTable.Value>>>))]

I am using the Coalesce function to return a value from my preferred ranking of Columns but I also want to include the name of the column that the value was derived from.
`i.e
Table:
Apples Pears Mangos
4 5
**SQL **
; with CTE as
(
Select
Coalesce(Apples,Pears,Mangos) as QTY_Fruit
from Table
) select *, column name from QTY_Fruit
from CTE
Result:
QTY_Fruit Col Name
4 Pears`
I am trying to avoid a case statement if possible because there are about 12 fields that I will need to use in my Coalesce. Would love for an easy way to pull the column name based on value in QTY_Fruit. I'm all ears if the answer lies outside the use of subqueries but I figured this would be a start.
I've a problem to in building a query for Python SQLite3 to do the following:
Count a word which appears in columns, if word appears more than 1 time count one.
I've attached a picture to illustrate my table format.
I tried this but the result still counts duplicate values with same ID.
"SELECT id, value, count(value) FROM table WHERE type like'%hi%' GROUP BY value ORDER BY COUNT(*)<1 DESC"
The result needs to be like:
Hi all you need can be achieved with GROUP BY clause.
This should help:
SELECT
id
,value
,1 AS cnt
FROM table
GROUP BY id, value
ORDER BY id
What you're looking for is DISTINCT clause or GROUP BY as mentioned by Peter.
for GROUP BY use this syntax:
SELECT
id
,value
,1 AS cnt
FROM table
GROUP BY id, value
for DISTINCT use this one:
SELECT DISTINCT
id
,value
,1 AS cnt
FROM table
a is value entered by user.
cur.execute('SELECT * FROM table WHERE Column-name LIKE ?', ('%{}%'.format(a,))
The database must show value matching with entered value. It shows for one column only. I want to retrieve record for more than one column. Need to use OR operator but not sure the syntax. Could anyone plz help me.
Just expand the where clause with more conditions, separated by OR - accordingly, you need to repeat the bind parameters:
cur.execute('SELECT * FROM table WHERE col1 LIKE ? OR col2 LIKE ?', ('%{}%'.format(a, a))
The structure of my column family is something like
CREATE TABLE product (
id UUID PRIMARY KEY,
product_name text,
product_code text,
status text,//in stock, out of stock
mfg_date timestamp,
exp_date timestamp
);
Secondary Index is created on status, mfg_date, product_code and exp_date fields.
I want to select the list of products whose status is IS (In Stock) and the manufactured date is between timestamp xxxx to xxxx.
So I tried the following query.
SELECT * FROM product where status='IS' and mfg_date>= xxxxxxxxx and mfg_date<= xxxxxxxxxx LIMIT 50 ALLOW FILTERING;
It throws error like No indexed columns present in by-columns clause with "equals" operator.
Is there anything I need to change in the structure? Please help me out. Thanks in Advance.
cassandra is not supporting >= so you have to change the value and have to use only >(greater then) and <(lessthen) for executing query.
You should have at least one "equals" operator on one of the indexed or primary key column fields in your where clause, i.e. "mfg_date = xxxxx"
I am using a composite primary key consisting of 2 strings Name1, Name2, and a timestamp (e.g. 'Joe:Smith:123456'). I want to query a range of timestamps given an equality condition for either Name1 or Name2.
For example, in SQL:
SELECT * FROM testcf WHERE (timestamp > 111111 AND timestamp < 222222 and Name2 = 'Brown');
and
SELECT * FROM testcf WHERE (timestamp > 111111 AND timestamp < 222222 and Name1 = 'Charlie);
From my understanding, the first part of the composite key is the partition key, so the second query is possible, but the first query would require some kind of index on Name2.
Is it possible to create a separate index on a component of the composite key? Or am I misunderstanding something here?
You will need to manually create and maintain an index of names if you want to use your schema and support the first query. Given this requirement, I question your choice in data model. Your model should be designed with your read pattern in mind. I presume you are also storing some column values as well that you want to query by timestamp. If so, perhaps the following model would serve you better:
"[current_day]:Joe:Smith" {
123456:Field1 : value
123456:Field2 : value
123450:Field1 : value
123450:Field2 : value
}
With this model you can use the current day (or some known day) as a sentinel value, then filter on first and last names. You can also get a range of columns by timestamp using the composite column names.
