I'm trying to update fields from three different tables but I'm getting some errors:
UPDATE
a, b, c
SET
a.Locked = 0,
b.Locked = 0,
c.Locked = 0,
a.LockedByUsername = 'zolomon',
b.LockedByUsername = 'zolomon',
c.LockedByUsername = 'zolomon',
a.LockedAt = CURRENT_TIMESTAMP,
b.LockedAt = CURRENT_TIMESTAMP,
c.LockedAt = CURRENT_TIMESTAMP
FROM
TableA AS a
INNER JOIN TableB as b ON n.Objid = o.Objid
INNER JOIN TableC as c ON n.Namnid = e.Namnid
WHERE
a.Namn1 = 'FirstName LastName' AND b.objektkod='SomeIdentifier'
And the errors:
Msg 102, Level 15, State 1, Line 2
Incorrect syntax near ','.
You can't update fields from multiple tables on a single update query. There error you are getting is because this is not permitted:
update a, b, c
Since you can only update one table per update command.
As pointed out by other answers, in SQL an UPDATE updates only one table. That's normally enough for most practical needs. If you want to update several tables at the same time, you can just put the updates inside a transaction, and the effect will normally be the same.
If you are concerned about getting different timestamps (for your field lockedAt) first look into your database docs to check if your CURRENT_TIMESTAMP function refers to the start time of the transaction (e.g. PostgreSQL).
you cannot update multiple tables in one statement. an option would be to use a stored procedure
We can update it with join like this
UPDATE table1
INNER join table2 on table1.id=table2.tab1_id
INNER join table3 on table1.id=table3.tab1_id
SET table1.status=1,table2.status=1,table3.status=1,table1.name='Premjith'
WHERE table1.id=1

Goal: Create a query to pull the closest cycle count event (Table C) for a product ID based on the inventory adjustments results sourced from another table (Table A).
All records from Table A will be used, but is not guaranteed to have a match in Table C.
The ID column will be present in both tables, but is not unique in either, so that pair of IDs and Timestamps together are needed for each table.
Current simplified SQL
SELECT
A.WHENOCCURRED,
A.LPID,
A.ITEM,
A.ADJQTY,
C.WHENOCCURRED,
C.LPID,
C.LOCATION,
C.ITEM,
C.QUANTITY,
C.ENTQUANTITY
FROM
A
LEFT JOIN
C
ON A.LPID = C.LPID
WHERE
A.facility = 'FACID'
AND A.WHENOCCURRED > '23-DEC-22'
AND A.ADJREASONABBREV = 'CYCLE COUNTS'
ORDER BY A.WHENOCCURRED DESC
;
This is currently pulling the first hit on C.WHENOCCURRED on the LPID matches. Want to see if there is a simpler JOIN solution before going in a direction that creates 2 temp tables based on WHENOCCURRED.
I have a functioning INDEX(MATCH(MIN()) solution in Excel but that requires exporting a couple system reports first and is extremely slow with X,XXX row tables.
If you are using Oracle 12 or later, you can use a LATERAL join and FETCH FIRST ROW ONLY:
SELECT A.WHENOCCURRED,
A.LPID,
A.ITEM,
A.ADJQTY,
C.WHENOCCURRED,
C.LPID,
C.LOCATION,
C.ITEM,
C.QUANTITY,
C.ENTQUANTITY
FROM A
LEFT OUTER JOIN LATERAL (
SELECT *
FROM C
WHERE A.LPID = C.LPID
AND A.whenoccurred <= c.whenoccurred
ORDER BY c.whenoccurred
FETCH FIRST ROW ONLY
) C
ON (1 = 1) -- The join condition is inside the lateral join
WHERE A.facility = 'FACID'
AND A.WHENOCCURRED > DATE '2022-12-23'
AND A.ADJREASONABBREV = 'CYCLE COUNTS'
ORDER BY A.WHENOCCURRED DESC;
I have two columns in the same table that I want to join in Postgresql but for some reason I’m getting this error. Don’t know how to figure it out. Please help.
[42P01] ERROR: relation "a" does not exist
Position: 10
X table contains two pools(ABC,XYZ), ids, numbers and description. If an ID exists in one pool but not in the other, it should update description column to “ADD”. Pools need to be joined on number.
UPDATE A
SET A.Description = 'ADD'
FROM X AS A
LEFT JOIN X AS B ON B.number = A.number
AND B.id = 'ABC'
WHERE A.id = 'XYZ'
AND B.number IS NULL
AND A.Description IS NULL;
With standard SQL you can't do a join as part of an update, but what you can do is include a subquery to select the id's to update. The subquery can contain a join. I'm not entirely clear on what you're actually trying to accomplish, but you could do something like this:
UPDATE x SET description='ADD' WHERE number IN (
SELECT a.number FROM x AS a
LEFT OUTER JOIN x AS b ON a.number=b.number AND a.id='XYZ' AND b.id='ABC'
WHERE b.number IS NULL
);
This will join the table x with itself and will select (and update) any numbers's that don't have a matching number in the 'ABC' and 'XYZ' zone.
PostgreSQL does have a UPDATE FROM syntax that does let you update with complex subqueries. It's more flexible but it's non-standard. You can find an example of this type of query here.
I'm trying create a SELECT with GROUP BY in Firebird but I can't have any success. How could I do this ?

Using GROUP BY doesn't make sense in your example code. It is only useful when using aggregate functions (+ some other minor uses). In any case, Firebird requires you to specify all columns from the SELECT column list except those with aggregate functions in the GROUP BY clause.
Note that this is more restrictive than the SQL standard, which allows you to leave out functionally dependent columns (ie if you specify a primary key or unique key, you don't need to specify the other columns of that table).
You don't specify why you want to group (because it doesn't make much sense to do it with this query). Maybe instead you want to ORDER BY, or you want the first row for each M_CODIGO.
I want this stored procedure to work concurrently, but as I see in PgAdmin it doesn't. One process is blocked by another one (waits him to finish). Seems to me, update query has no problems with being running concurrently. So this is all about INSERT, am I right? I tried to set ROW SHARE EXCLUSIVE LOCK on update query, but I've reached deadlock.
UPDATE product p SET category_id = m.internal_category_id, category_from=m.cat_prior FROM main_table m
WHERE p.mpn=m.mpn AND
p.vendor_id = m.internal_vendor_id AND
m.new_prod=false and
m.internal_category_id IS NOT NULL AND
(category_from is null or category_from<=m.cat_prior);
INSERT INTO product(vendor_id, category_id, mpn, name, category_from)
SELECT DISTINCT ON(m.mpn, m.internal_vendor_id) m.internal_vendor_id, m.internal_category_id, m.mpn, m.prod_name, m.cat_prior
FROM main_table m
LEFT OUTER JOIN product ON product.mpn=m.mpn AND product.vendor_id=m.internal_vendor_id
WHERE m.new_prod='1' AND m.internal_vendor_id IS NOT NULL
AND product.mpn IS NULL;
UPDATE main_table m SET internal_product_id = p.id
FROM product p
WHERE p.mpn=m.mpn AND p.vendor_id = m.internal_vendor_id ;
UPDATE vendor SET has_products = true FROM (SELECT DISTINCT v.id as id FROM vendor v INNER JOIN product p ON p.vendor_id = v.id) AS r WHERE vendor.id = r.id;
UPDATE vendor SET has_products = false FROM (SELECT DISTINCT v.id as id FROM vendor v LEFT JOIN product p ON p.vendor_id = v.id WHERE p.vendor_id IS NULL) AS r WHERE vendor.id = r.id;
Seems to me, update query has no problems with being running
concurrently. So this is all about INSERT, am I right?
Both can be problematic but UPDATE tends to be more problematic with regard to interlocking.
When an UPDATE modifies a row and another UPDATE tries to modify the same row, the second is put to wait until the first transaction commits or rolls back.
On the other hand, when two INSERTs hit the same table, the second one is made to wait only if there's a unique index on the table and both statements are trying to insert the same indexed value. Which is unusual because that would lead to an index violation error unless the first transaction aborts.
Just by looking at a piece of code, it's hard to know whether concurrent calls will hit the same rows or not, it depends on the data. However in your case it's a bit suspicious that your first UPDATE doesn't seem to take any parameter.
I was having some trouble with an SQL 2k sproc and which we moved to SQL 2k5 so we could used Table Value UDF's instead of Scalar UDF's.
This is simplified, but this is my problem.
I have a temporary table that I fill up with product information. I then pass that product information into a UDF and return the information back to my main results set. It doesn't seem to work.
Am I not allowed to pass a Temporary Table value into an CROSS APPLY'd Table Value UDF?
--CREATE AND FILL #brandInfo
SELECT sku, upc, prd_id, cp.customerPrice
FROM products p
JOIN #brandInfo b ON p.brd_id=b.brd_id
CROSS APPLY f_GetCustomerPrice(b.priceAdjustmentValue, b.priceAdjustmentAmount, p.Price) cp
--f_GetCUstomerPrice uses the AdjValue, AdjAmount, and Price to calculate users actual price
When I put dummy values in for b.priceAdjustmentValue and b.priceAdjustmentAmount it works great. But as soon as I try to load the temp table values in it bombs.
Msg 207, Level 16, State 1, Line 140
Invalid column name 'b.priceAdjustmentValue'.
Msg 207, Level 16, State 1, Line 140
Invalid column name 'b.priceAdjustmentAmount'.
Have you tried:
--CREATE AND FILL #brandInfo
SELECT sku, upc, prd_id, cp.customerPrice
FROM products p
JOIN #brandInfo b ON p.brd_id=b.brd_id
CROSS APPLY (
SELECT *
FROM f_GetCustomerPrice(b.priceAdjustmentValue, b.priceAdjustmentAmount, p.Price) cp
)
--f_GetCUstomerPrice uses the AdjValue, AdjAmount, and Price to calculate users actual price
Giving the UDF the proper context in order to resolve the column references?
EDIT:
I have built the following UDF in my local Northwind 2005 database:
CREATE FUNCTION dbo.f_GetCustomerPrice(#adjVal DECIMAL(28,9), #adjAmt DECIMAL(28,9), #price DECIMAL(28,9))
RETURNS TABLE
AS RETURN
(
SELECT Level = 'One', AdjustValue = #adjVal, AdjustAmount = #adjAmt, Price = #price
UNION
SELECT Level = 'Two', AdjustValue = 2 * #adjVal, AdjustAmount = 2 * #adjAmt, Price = 2 * #price
)
GO
And referenced it in the following query without issue:
SELECT p.ProductID,
p.ProductName,
b.CompanyName,
f.Level
FROM Products p
JOIN Suppliers b
ON p.SupplierID = b.SupplierID
CROSS APPLY dbo.f_GetCustomerPrice(p.UnitsInStock, p.ReorderLevel, p.UnitPrice) f
Are you certain that your definition of #brandInfo has the priceAdjustmentValue and priceAdjustmentAmount columns defined on it? More importantly, if you are putting this in a stored procedure as you mentioned, does there exist a #brandInfo table already without those columns defined? I know #brandInfo is a temporary table, but if it exists at the time you attempt to create the stored procedure and it lacks the columns, the parsing engine may be getting tripped up. Oddly, if the table doesn't exist at all, the parsing engine simply glides past the missing table and creates the SP for you.
