Looping through columns in Postgresql - postgresql

I want to execute the following query 3 times for 3 different columns
(pc = t1.postal_code, t1.postal_code_2, t1.postal_code_3).
update addresses t1 set
admin_name1 = t.admin_name1,
admin_name2 = t.admin_name2,
admin_name3 = t.admin_name3,
admin_name4 = t.admin_name4,
from (
select * from all_countries) t
where t.postal_code = pc and t1.country_ = t.country ;
Is there are way of writing the code only once, e.g. by means of a loop, and how can I implement it?

Can someone help me with the update function in Matlab to move values to MySQL?

I'm dealing with a problem with the update function in Matlab.
conn=database('MySQL','user','password');)
selectquery_select = 'SELECT * FROM inputs WHERE i_read = 0';
data_select = select(conn,selectquery_select);
for j=1:size(data_select)
id_data = data_select(j,1);
id_data = string(id_data.(1));
time_data = data_select(j,4);
time_data = string(time_data.(1));
time_dataform = datetime(time_data,'InputFormat','yyyy-MM-dd HH:mm:ss');
y0=data_select(j,2);
y0 = str2num(string(y0.(1)));
r0=data_select(j,3);
r0 = str2num(string(r0.(1)));
if id_data == "115"
run("C:\Users\...\uu.m")
update(conn,'inputs','i_read',1,'WHERE (ID_code = "115") AND WHERE (i_Time = time_data)');
end
end
Basically, I'm taking some value from the database when i_read is equal to 0 (i_read is a boolean variable in the database that should give 1 if the value is already processed and 0 if not). After a value is read, we want to change the i_read in the database from 0 to 1. We decide to use the update function, but this gave us the following error:
Error using database.odbc.connection/update
Too many input arguments.
Error in Patient_Identification (line 57)
update(conn,'inputs','i_read',1,'WHERE (ID_code = "112") AND WHERE (i_Time = ', time_data,')');
Someone is able to help us with this problem? Thank you.

How to calculate the percentage(%) in postgresql

I am not able to calculate the % in postgresql
Below the my code
v_total_repro_count = (select count(pm_task_run_bug_repro_id) from project.pm_task_run_bug_repro
where pm_task_run_bug_detail_id = 605)--5;
v_repro_count = (select count(pm_task_run_bug_repro_id) from project.pm_task_run_bug_repro
where execution_status = 'Reprod' and pm_task_run_bug_detail_id = 605)--3;
v_impact = select (5/3)*100; = answer = 100
v_impact = select (3/5)*100; = answer = 0
the answer getting 0 and 100 instead of 60%
Cast value to numeric
SELECT ROUND(( 3::NUMERIC/5::NUMERIC ) * 100);
If you want floating point results, you should use at least one float in your calculation, such that the entire expression is promoted to floating point:
select (3.0 / 5) * 100; -- returns 60

Update table rows in Postgresql taking too much time

I am trying to update around 6000 rows in a table but my query never finishes.
I have put the data to be updated in a temp table and using a join to update rows.
This was working pretty fast in Sql Server but in Postgresql it never finishes.
I am updating around 40 columns.
Here is the sql I am running.
UPDATE "STG_magento_de".sales_flat_order
SET customer_id = b.customer_id
,created_at = b.created_at
,updated_at = b.updated_at
,coupon_code = b.coupon_code
,box_id = b.box_id
,beautytrends_glossydots = b.beautytrends_glossydots
,billing_address_id = b.billing_address_id
,shipping_address_id = b.shipping_address_id
,base_discount_amount = b.base_discount_amount
,base_discount_canceled = b.base_discount_canceled
,base_discount_invoiced = b.base_discount_invoiced
,base_discount_refunded = b.base_discount_refunded
,base_grand_total = b.base_grand_total
,base_shipping_amount = b.base_shipping_amount
,base_shipping_canceled = b.base_shipping_canceled
,base_shipping_invoiced = b.base_shipping_invoiced
,base_shipping_refunded = b.base_shipping_refunded
,base_shipping_tax_amount = b.base_shipping_tax_amount
,base_shipping_tax_refunded = b.base_shipping_tax_refunded
,base_subtotal = b.base_subtotal
,base_subtotal_canceled = b.base_subtotal_canceled
,base_subtotal_invoiced = b.base_subtotal_invoiced
,base_tax_amount = b.base_tax_amount
,base_tax_canceled = b.base_tax_canceled
,base_tax_invoiced = b.base_tax_invoiced
,base_tax_refunded = b.base_tax_refunded
,base_to_global_rate = b.base_to_global_rate
,base_to_order_rate = b.base_to_order_rate
,base_total_canceled = b.base_total_canceled
,base_total_invoiced = b.base_total_invoiced
,base_total_invoiced_cost = b.base_total_invoiced_cost
,base_total_offline_refunded = b.base_total_offline_refunded
,base_total_online_refunded = b.base_total_online_refunded
,base_total_paid = b.base_total_paid
,base_total_qty_ordered = b.base_total_qty_ordered
,base_total_refunded = b.base_total_refunded
,increment_id = b.increment_id
,order_type = b.order_type
,STATUS = b.STATUS
,is_chargerun = b.is_chargerun
,chargeback_flag = b.chargeback_flag
,gift_message_id = b.gift_message_id
,dispatch = b.dispatch
FROM "STG_magento_de".sales_flat_order a
JOIN "STG_magento_de".sales_flat_order_temp b ON a.entity_id = b.entity_id
From the manual:
Note that the target table must not appear in the from_list, unless you intend a self-join (in which case it must appear with an alias in the from_list).
(emphasis mine)
So you actually want:
UPDATE "STG_magento_de".sales_flat_order
SET customer_id = b.customer_id,
....
from sales_flat_order_temp b --<< do NOT repeat the target table here
where "STG_magento_de".sales_flat_order = b.entity_id`
Unrelated, but: you should really avoid those dreaded quoted identifiers. They are much more trouble than they are worth.

SystemVerilog array random seed of Shuffle function

I get the same output everytime I run the code below.
module array_shuffle;
integer data[10];
initial begin
foreach (data[x]) begin
data[x] = x;
end
$display("------------------------------\n");
$display("before shuffle, data contains:\n");
foreach (data[x]) begin
$display("data[%0d] = %0d", x, data[x]);
end
data.shuffle();
$display("------------------------------\n");
$display("after shuffle, data contains:\n");
foreach (data[x]) begin
$display("data[%0d] = %0d", x, data[x]);
end
end
endmodule
Output:
------------------------------
before shuffle, data contains:
data[0] = 0
data[1] = 1
data[2] = 2
data[3] = 3
data[4] = 4
data[5] = 5
data[6] = 6
data[7] = 7
data[8] = 8
data[9] = 9
------------------------------
after shuffle, data contains:
data[0] = 8
data[1] = 6
data[2] = 7
data[3] = 9
data[4] = 5
data[5] = 0
data[6] = 1
data[7] = 4
data[8] = 2
data[9] = 3
Is there a way to seed the randomization of the shuffle function?
Shuffle returns the same result every time because you probably run the simulator with the same seed. This is the intended behavior, because when you run a simulation and find a bug, you want to be able to reproduce it, regardless of any design (and to some extent testbench) changes. To see a different output, try setting the seed on the simulator command line. For Incisive this is:
irun -svseed 1 // sets the seed to 1
irun -svseed random // will set a random seed
It's also possible to manipulate the seed of the random number generator using set_randstate, but I wouldn't mess with that.

Converting classic ASP ADODB script to TSQL

Hi i inherited a load of old classic ASP code that makes some updates to some tables in what i think was old MS access db.
The databases have now been converted to SQL and work OK, however i have a need to convert some old ASP code to the equivalent TSQL. TSQL is NOT my strong point and would appreciate some help converting the vb script to the equivalent TSQL for a stored procedure called 'UpdateCircuitOrdersComments' its not the basic syntax i'm struggling with, its more what can be done IE FOR's IF's Cases, loops etc in order to achieve the below in sql.
I know the code below is not great or could be done far better, but that's what i inherited sorry.
Every field is available to me via c# parameters passed to the sproc using ajax apart from the "Contract Period"
Looking forward to learning from any sound advice from you guys...
The script is below:

The loops don't appear to do much other then iterate over the record set. It is unlikely that you will need to do this in T-SQL as you can probably deduce everything from queries.
Most of it just looks like update statements
-- Check that current maintenance rate will be superseded
UPDATE maintenancetable
SET StartDate = #startSerial,
EndDate = #endSerial,
CircuitNum = #circuitNumber,
ModifiedDate = CURRENT_TIMESTAMP
WHERE CircuitID=#circuitId
AND (Startdate < #startSerial OR EndDate > #endSerial)
The contract period is a bit confusing it seems to be getting the first item of an array so maybe this is the equivalent of
SELECT TOP 1 ContractPeriod FROM circuits WHERE ID=#id
-- ? ORDER BY ContractPeriod ?
