If user is entering 678.98 then it should display only 678 in one of the field of a window.
I have declare that field as numeric in database and number type reference in tables and columns in openbravo.
Use Math.floor()
import java.lang.Math;
...
value = 678.98;
roundeddown = Math.floor(value); // roundeddown == 678
See also this page about another rounding example.
Working directly with PostgreSql, use the floor() function
To insert data
INSERT INTO table ... VALUES( floor(678.98) ) ...
To select data
SELECT floor( field ) FROM table WHERE ....
Set Integer type reference in tables and columns in openbravo.

So, In the table, there are 3 columns as per Image , 3rd one is Record(Struct), conntaing 2 structs old and new. Inside those structs there are columns and values.
I can access each final column by this -change.old.name , But I want to convert them as normal columns and create another taable with that ?
tried unnest but doesn't work as it's not array.
Data structure image
UPDATE :
Finally got it sorted. Should select and convert all columns by selecting all of the nested data and set the alias as how we want or replace dot with an underscore. Then create a table with that.
create table abc
as
select
ID
,Created_on
,Change.old.add as Change_old_add
,Change.old.name as Change_old_name
,Change.old.count_people as Change_old_count_people
,Change.new.add as Change_new_add
,Change.new.name as Change_new_name
,Change.new.count_people as Change_new_count_people
FROM `project.Table`

I have a table with a few key columns created with nvarchar(80) => unicode.
I can list the full dataset with SELECT * statement (Table1) and can confirm the values I need to filter are there.
However, I can't get any results from that table if I filter rows by using as input an alphabet char on any column.
Columns in table1 stores values in cyrilic characters.
I know it must have to do with character encoding => what I see in the result list is not what I use as input characters.
Unicode nvarchar type should resolve automatically this character type mismatch.
What do you suggest me to do in order to get results?
Thank you very much.

I'm working on a website in node js and use SQLite as a database for the first time.
I want to be able to use real for some form data and I noticed that every real in my database are converted to integer once the query is made.
To vizualize the database i am using DB Browser and i checked if the columns are defined as REAL which they are.
If i try to query a data set as 0.1 in my DB I get this :
sqlite> select step_variable
from variables
where id=38;
0.0
After trying as suggested the command TYPEOF(step_variable) it returned :
0.0|real
In the SQLite CREATE TABLE command, one defines a data type affinity, not a data type. SQLite supports the following five column affinities: TEXT, NUMERIC, INTEGER, REAL, NONE.
Thus the data type you specify when creating a table does not enforce a certain data type. You can supply any data type you want or even omit the data type.
CREATE TABLE table1(
column1 ABC,
column2 Others,
column3 WHATEVER);
CREATE TABLE table2(column1, column2, column3);
Populate tables:
INSERT INTO table1 VALUES( 1, 'my text', 123.45);
INSERT INTO table2 VALUES( 1, 'my text', 123.45);
Now let us check what SQLite made out of it:
SELECT column1, TYPEOF(column1) from table1
SELECT column2, TYPEOF(column1) from table1
SELECT column3, TYPEOF(column1) from table1
With:
column TYPEOF(column)
------------------------
1 INTEGER
my text TEXT
123.45 REAL
When you go through a query result e.g. by using sqlite2_step you can use the sqlite3_column_type statement to confirm the column type - unless you know the result anyway and simply cast the result to the data type expected.

I found the solution it was simply that i didn't save my file after modifying it.
I'm trying to retrieve rows from a table where a subquery matches an variable. However, it seems as if the WHERE clause only lets me compare fields of the selected tables against a constant, variable or subquery.
I would expect to write something like this:
DATA(lv_expected_lines) = 5.
SELECT partner contract_account
INTO TABLE lt_bp_ca
FROM table1 AS tab1
WHERE lv_expected_lines = (
SELECT COUNT(*)
FROM table2
WHERE partner = tab1~partner
AND contract_account = tab1~contract_account ).
But obviously this select treats my local variable as a field name and it gives me the error "Unknown column name "lv_expected_lines" until runtime, you cannot specify a field list."
But in standard SQL this is perfectly possible:
SELECT PARTNER, CONTRACT_ACCOUNT
FROM TABLE1 AS TAB1
WHERE 5 = (
SELECT COUNT(*)
FROM TABLE2
WHERE PARTNER = TAB1.PARTNER
AND CONTRACT_ACCOUNT = TAB1.CONTRACT_ACCOUNT );
So how can I replicate this logic in RSQL / Open SQL?
If there's no way I'll probably just write native SQL and be done with it.
The program below might lead you to an Open SQL solution. It uses the SAP demo tables to determines the plane types that are used on a specific number of flights.
REPORT zgertest_sub_query.
DATA: lt_planetypes TYPE STANDARD TABLE OF s_planetpp.
PARAMETERS: p_numf TYPE i DEFAULT 62.
START-OF-SELECTION.
SELECT planetype
INTO TABLE lt_planetypes
FROM sflight
GROUP BY planetype
HAVING COUNT( * ) EQ p_numf.
LOOP AT lt_planetypes INTO DATA(planetype).
WRITE: / planetype.
ENDLOOP.
It only works if you don't need to read fields from TAB1. If you do you will have to gather these with other selects while looping at your results.
For those dudes who found this question in 2020 I report that this construction is supported since ABAP 7.50. No workarounds are needed:
SELECT kunnr, vkorg
FROM vbak AS v
WHERE 5 = ( SELECT COUNT(*)
FROM vbap
WHERE kunnr = v~kunnr
AND vkorg = v~vkorg )
INTO TABLE #DATA(customers).
This select all customers who made 5 sales orders within some sales organization.
In ABAP there is no way to do the query as in NATIVE SQL.
I would advice not to use NATIVE SQL, instead give a try to SELECT/ENDSELECT statement.
DATA: ls_table1 type table1,
lt_table1 type table of table1,
lv_count type i.
SELECT PARTNER, CONTRACT_ACCOUNT
INTO ls_table1
FROM TABLE1.
SELECT COUNT(*)
INTO lv_count
FROM TABLE2
WHERE PARTNER = TAB1.PARTNER
AND CONTRACT_ACCOUNT = TAB1.CONTRACT_ACCOUNT.
CHECK lv_count EQ 5.
APPEND ls_table1 TO lt_table1.
ENDSELECT
Here you append to ls_table1 only those rows where count is equals to 5 in selection of table2.
Hope it helps.
I know if I want to do this query by cqlengine:
select * from test
I should make a model to test table then do this:
testModel.objects.all()
this code will return all columns in test table but what if I want to do this:
select field1 from test
Is there any way to select optional fields from a table by cqlengine or I should have all column in query?
Thanks for help
You can use the method values_list() method on a queryset in cqlengine to just retrieve the specified values. Simply include the names of the columns to retrieve as string arguments.
So you could do something like:
field1_list = MyModel.objects.all().values_list('field1')
