I have two tables in a sql database, I am trying to update a column from my committed table (committedtbl) with values from my vendor table (vendortbl) based on a common column from both tables.
There is a column with the vendor identification number (vendorno) in both tables, I tried adding the vendor description (vendorname) column from the vendortbl to the committedtbl but there are no values in it.
I need to insert values into the vendorname based on the corresponding numbers from vendorno... How do I accomplish this?
The vendorname column already exists in my committedtbl.
I have tried this, but got an error:
update v_vendorname
set v_vendorname = v_vendorno
from vendortbl vt
where v_vendorno = vt.v_venkey
update committedtbl
set c.vendorname = v.vendorname
from committedtbl c
inner join vendortbl v on v.vendorno = c.vendorno

Just to level set: i'm working within a Vertica database using SQL.
Let's say i have two tables: Table A and Table B. Let's also say that Table A is my final/master table used for data vis within Tableau (or something akin), and that Table B feeds certain columns into Table A based on matches within a tertiary table, Table C (which is not relevant to this conversation).
As is, Table A has columns:
ProgramName [varchar(50)]
CustomerName [varchar(50)]
Total_Cost [numeric(18,4)]
As is, Table B has columns:
CustomerCode [varchar(10)]
Total_Cost [numeric(18,4)]
What I would like to do is update Table A's CustomerName column to equal CustomerCode in Table B where the columns of total_cost_dollars equal each other across tables.
I've run this left join query to ensure that, when I do update Table A's CustomerName to equal CustomerCode, the total cost columns are exact/true matches for my entire data set.
SELECT
A.ProgramName,
A.CustomerName,
A.total_cost_dollars,
B.CustomerCode,
B.total_cost_dollars
FROM
TableA A
LEFT JOIN
TableB B
ON
B.total_cost_dollars = A.total_cost_dollars
WHERE
A.CustomerName IS NULL;
Any idea on how to solve this problem?
Since Vertica supports merge query, you can use merge statement:
merge into TableA A
using TableB B
ON (B.total_cost_dollars = A.total_cost_dollars)
when matched then
update
set
A.CustomerName = B.CustomerCode
where
A.CustomerName IS NULL;
I have tableA with the columns ID, ColumnHeader, Value.
I'm trying to update tableB where ID, and the value in tableB.ColumnHeader with tableB.Value.
Essentially, the column headers for tableB are in a column in Table A and not column headers themselves.
I'm stuck on specifying the table name. For example, how do I run this query when I only have tablename.____ where the blank is in a column in a separate table?
update tableB set table.____ .....
As seen in the screenshot below, in Table B, 4 should become 1, and 8 should become 2, and 12 should become 3. Thanks so much.
this is a example from Northwind database:
UPDATE dbo.Products
SET dbo.Products.CategoryID = c.CategoryID
FROM Products
INNER JOIN dbo.Categories c ON dbo.Products.CategoryID = c.CategoryID
I am not getting which table and column you want to update with which table and column.
also relationship is not clear.
This doesn't make sense to me. Are you trying to update table B or A? Are there like values in table B and A that you want updated?
The basic code is as shown below:
update tableb
set column id = 'value you're updating'
where column id = 'value you're looking for' --always make this unique like a key etc.
I have 3 tables: raw_sales, sales and details. raw_sales is being populated using COPY from a txt file. All the fields in raw_sales are either string or text. After importing, we run an sql to populate sales and details. There is a foreign key (sale_id) in details. Here's a sample INSERT command that we use to populate sales and details.
INSERT INTO sales (source, source_identifier)
(SELECT DISTINCT
'FOO' AS source,
"identifier" AS source_identifier
FROM raw_sales
LEFT JOIN sales
ON sales.source_identifier = raw_sales.identifier
AND sales.source = 'FOO'
WHERE sales.id IS NULL
AND identifier IS NOT NULL);
INSERT INTO details (sale_id, description)
(SELECT DISTINCT
sales.id AS sale_id,
"improvements" as description
FROM raw_sales
JOIN sales
ON sales.source_identifier = raw_sales.identifier
AND sales.source = 'FOO'
LEFT JOIN details AS existing
ON existing.sale_id = sales.id
WHERE existing.id IS NULL
AND "improvements" != '');
This seems to work fine. After this, there's another sql that's being ran to update existing tables. The query is as follows
UPDATE details SET
description = "improvements"
FROM raw_sales
JOIN sales
ON sales.source_identifier = raw_sales.identifier
AND sales.source = 'FOO'
JOIN details AS existing
ON existing.sale_id = sales.id
WHERE existing.id IS NOT NULL;
This query updates all rows in the details table to a single value, the first non-empty value from raw_sales table. How can I change the above sql so that it updates the existing records in the details table?
There are several problems with your query:
if details.id is a primary key (field id typically is), then what is the point in comparing it to NOT NULL? You're not using any left joins, there is no way it could possibly be NULL if it truly is an identifier.
UPDATE table t SET ... FROM ... requires linking the table t with something on the FROM section, but you're not, therefore each row of table will be updated to any single random row from the FROM results.
Perhaps you want to do this:
UPDATE details SET
description = "improvements"
FROM raw_sales
JOIN sales ON (sales.source_identifier = raw_sales.identifier AND sales.source = 'FOO')
JOIN details AS existing ON (existing.sale_id = sales.id)
WHERE existing.id = details.id;
I have one table named: ORDERS
this table contains OrderNumber's which belong to the same person and same address lines for that person.
However sometimes the data is inconsistent;
as example looking at the table screenshot: Orders table with bad data to fix -
you all can noticed that orderNumber 1 has a name associated to and addresses line1-2-3-4. sometimes those are all different by some character or even null.
my goal is to update all those 3 lines with one set of data that is already there and set equally all the 3 rows.
to make more clear the result expected should be like this:
enter image description here
i am currently using a MERGE statement to avoid a CURSOR (for loop )
but i am having problems to make it work
here the SQL
MERGE INTO ORDERS O USING
(SELECT
INNER.ORDERNUMBER,
INNER.NAME,
INNER.LINE1,
INNER.LINE2,
INNER.LINE3,
INNER.LINE4
FROM ORDERS INNER
) TEMP
ON( O.ORDERNUMBER = TEMP.ORDERNUMBER )
WHEN MATCHED THEN
UPDATE
SET
O.NAME = TEMP.NAME,
O.LINE1 = TEMP.LINE1,
O.LINE2 = TEMP.LINE2,
O.LINE3 = TEMP.LINE3,
O.LINE4 = TEMP.LINE4;
the biggest issues i am facing is to pick a single row out of the 3 randomly - it does not matter whihc of the data - row i pick to update the line/s
as long i make the records exaclty the same for an order number.
i also used ROWNUM =1 but it in multip[le updates will only output one row and update maybe thousand of lines with the same address and name whihch belong to an order number.
order number is the join column to use ...
kind regards
A simple correlated subquery in an update statement should work:
update orders t1
set (t1.name, t1.line1, t1.line2, t1.line3, t1.line4) =
(select t2.name, t2.line1, t2.line2, t2.line3, t2.line4
from orders t2
where t2.OrderNumber = t1.OrderNumber
and rownum < 2)
I have a two table 'Inventory' and 'Tendor' where Inventory has primary key pk_id ,i updated 'Inventory' table when Inventory.ti_name = Tendor.ki_name by using following query
Update Inventory A set (Used_NAME, ACCOUNT_NUMBER, ti_STATUS)
= (Select B.Using_NAME, B.ACCOUNT_NO, B.ki_STATUS from
Tendor B where A.ti_name = B.ki_name and a.pk_id is not null);
Anything wrong in this query or any optimized one??
After updation for those who is not satisfying the condition Inventory.ti_name = Tendor.ki_name i want to insert it as new rows in 'Inventory' table with primary key pk_id should be changed
how to do this? for pk_id do i need to do some logic like 'SEQ.NEXTVAL FROM DUAL'
Can anybody suggest a query
This query updates searches matching rows in tables inventory and tendor. When both tables contain row with the same value of ki_name, it updates row in table inventory. All rows from tendor, that was not found in inventory, will be inserted there:
merge into Inventory a
using Tendor b
on (A.ti_name = B.ki_name)
when matched then update
set a.Used_NAME = B.Using_NAME,
a.ACCOUNT_NUMBER = B.ACCOUNT_NO,
a.ti_STATUS = B.ki_STATUS
when not matched then
insert (pk_id, Used_NAME, ACCOUNT_NUMBER, ti_STATUS)
values (your_seq.nextval, B.Using_NAME, B.ACCOUNT_NO, B.ki_STATUS)
Also you can use sequence in insert statement.
