I have two tables in my database, bill_datail and bill_log. I want to delete one record from table bill_log and after that trigger an action to do something in table bill_detail. My code for delete is the following:
DELETE FROM [mydatabase].[dbo].[Bill_Log]
WHERE [mydatabase].[dbo].[Bill_Log].[CU_BILL_ID] in
(SELECT
FROM [mydatabase].[dbo].[Bill_Log],[mydatabase].[dbo].[Bill_Detail]
where [mydatabase].[dbo].[Bill_Log].bill_id=37
and [mydatabase].[dbo].[Bill_Log].bill_id=[mydatabase].[dbo].[CU_Bill_Detail].cu_bill_id
and [mydatabase].[dbo].[Bill_Detail].Pay_date>20130206
and [CL_Com_Rec_Description] like '%اoffpage%'
and [mydatabase].[dbo].[Bill_Log].amount<0
and [mydatabase].[dbo].[Bill_Log].[Com_Act_Date]='2013/02/07')
go
CREATE TRIGGER [mydatabase].[dbo].[Bill_Log]
ON [mydatabase].[dbo].[Bill_Log]]
AFTER Delete
AS
---
BEGIN
-- get 'amount' from deleted record and sum it to field 'amount' of bill detail
END
But in delete action I get the following error:
'Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.
And I don't know how to fix the error and do the second part.
You only need to get a list of CU_BILL_ID to search. So remove all other fields from inner query and just select CU_BILL_ID.
DELETE FROM [mydatabase].[dbo].[CU_Bill_Log]
WHERE [mydatabase].[dbo].[CU_Bill_Log].[CU_BILL_ID] in
(SELECT cu_bill_id
FROM [mydatabase].[dbo].[CU_Bill_Detail]
where Pay_date>13930206)
and [mydatabase].[dbo].[CU_Bill_Log].cu_bill_id=37
and [mydatabase].[dbo].[CU_Bill_Log].cu_bill_id=
and [mydatabase].[dbo].[CU_Bill_Detail].
and [CL_Com_Rec_Description] like '%اoffpage%'
and [mydatabase].[dbo].[CU_Bill_Log].amount<0
and [mydatabase].[dbo].[CU_Bill_Log].[CL_Com_Act_Date]='2013/02/07'
go
Try this please.
if you want use of "in" keyword in your main query ,
the subquery must return just one column as result
Select ID,F_Name,L_Name
From Clients
Where ID in(
Select ClientID
From Orders
Where OrderNo > 120
)

In this query I inserting records into a new empty table I created. These records are derived from another table where I am left joining that table to itself, in order to output records that are not included in the recent table that is appended on top of an older table. So basically it outputs records that were deleted.

AND ot2.`account_number` IS NULL;
COMMIT;
END
I get an error stating: "SQL Error: Column "insert_date" in field list is ambiguous.
I'm not sure why because I have specified which table I am grabbing "insert_date" from when INSERTING and when SELECTING and JOINING..
Every row in your query has two columns called insert_date: one from the table you've aliased as "ot1", and one from the table (as it happens, the same table) you've aliased as "ot2".
The database system doesn't know which one you want, so you have to tell it by writing either "ot1.insert_date" or "ot2.insert_date", just as you do elsewhere in the query:
... ot2.`insert_date` = '2022-12-20'
...
... ot1.`insert_date` = '2022-12-10'
The same is true of the other columns you've listed to select.
You need to change this
SELECT
`insert_date`,
`updated`,
`account_number`,
`id_number`
to this
SELECT
ot1.`insert_date`,
ot1.`updated`,
ot1.`account_number`,
ot1.`id_number`
or this
SELECT
ot2.`insert_date`,
ot2.`updated`,
ot2.`account_number`,
ot2.`id_number`
or some combination
Issue
SQL Error: Column "insert_date" in field list is ambiguous error means that the query is trying to reference the "insert_date" column from both tables, ot1 and ot2.
Try the following:
SELECT
ot1.`insert_date`,
ot1.`updated`,
ot1.`account_number`,
ot1.`id_number`
Also, you have a typo in your query:
ON ot1.`account_number` = vdcaas2.`account_number` -> ON ot1.`account_number` = ot2.`account_number`
I have a table that I want to update that contains a column called 'expiration_days'. What I am doing is trying to update the records in the 'expiration_days' column by using an 'alias column' (not sure what to call it) that is apart of a subquery where I calculated the number of days until a user's password has expired. The column from the subquery that I want to take the values from and update them in the actual table is called 'countdown'. I named the subquery results 'query' (derived table). So far I have this:
UPDATE LOGIN_INFO
SET expiration_days = query.countdown
FROM (
select li.name as name, countdown = 365 - datediff(day, sl.pwdate, getdate())
from master..syslogins sl, LOGIN_INFO li
where li.name = sl.name) query
WHERE LOGIN_INFO.name = query.name
The issue I am having is I get this error: You cannot use a derived table in the FROM clause of an UPDATE or DELETE statement. ( I also get: Incorrect syntax near ')' on the subquery where clause)
Is there a way I can take the results from the calculated column in a select statement and update the column in the LOGIN_INFO table in one query or some other easy clean way?
Perhaps something along the lines of:
update login_info
set expiration_days = (select 365 - datediff(day,s1.pwdate,getdate())
from master..syslogins s1
where s1.name = li.name)
from login_info li
where exists(select 1
from master..syslogins s2
where s2.name = li.name)
NOTES:
the exists() clause is added to insure we don't erroneously update a row in login_info that doesn't have a match in syslogins, otherwise OP will need to modify the logic accordingly (ie, what to set expiration_days to if a matching rows does not exist in syslogins?)
if syslogins.pwdate is NULLable (I don't have access to a running ASE instance at the moment) then OP will need additional logic to handle the scenario where s1.pwdate is NULL; default countdown to some hardcoded value? or perhaps modify the exists() to include the additional clause and s2.pwdate is not NULL?
I'm unable to delete the rows of table A where its keys are WO_NO and ROW_NO.
I wrote the following query but giving an error saying, invalid relational operation.
This is what I tried.
begin
DELETE FROM A
WHERE WO_NO,ROW_NO in (SELECT WO_NO,ROW_NO
FROM G1614617_1
MINUS
SELECT WO_NO,ROW_NO
FROM hirplk_test1);
dbms_output.put_line(SQL%ROWCOUNT);
end;
/
The select query returns the row values WO_NO and ROW_NO. but I cannot delete the records from tab A. Can someone please correct me.
You need to put the two columns between parentheses if you want to compare them with a two column sub-query:
DELETE FROM A
WHERE (WO_NO,ROW_NO) in (SELECT WO_NO,ROW_NO
FROM G1614617_1
MINUS
SELECT WO_NO,ROW_NO
FROM hirplk_test1);
I m struggling to update one column for a table with a sub query. I have a table where currently one of the values is null.
Currently I have:
UPDATE DW1_PURCHASES SET DW1_PURCHASES.TOTAL_AMT =
(
SELECT DW1_PURCHASES.QUANTITY * DW1_PRODUCTS.PRICE
FROM DW1_PURCHASES, DW1_PRODUCTS
WHERE DW1_PURCHASES.PRODUCT_ID = DW1_PRODUCTS.PRODUCT_ID
)
Although subquery returns data which I need to insert I get a error of single row subquery returns multiple rows.How do I basically shift subquery result to the table?
Thanks.
You don't have to JOINthe update table inside the sub-query. Just correlate the sub-query with update table
UPDATE DW1_PURCHASES
SET DW1_PURCHASES.TOTAL_AMT =
(
SELECT DW1_PURCHASES.QUANTITY * DW1_PRODUCTS.PRICE
FROM DW1_PRODUCTS
WHERE DW1_PURCHASES.PRODUCT_ID = DW1_PRODUCTS.PRODUCT_ID
)
Note : If your DW1_PRODUCTS table has duplicated PRODUCT_ID then even now there is a possibility to get the same error
I'm quite new to SQL and I'm having issues with deleting a selected row/s from a table.
I've written a query that selects the desired rows from the table, but when I try to execute DELETE FROM table_name WHERE EXISTS it deletes all the rows in the database.
Here is my complete query:
DELETE FROM USR_PREF WHERE EXISTS (
SELECT *
FROM USR_PREF
WHERE USR_PREF.USR_ID = 1
AND ((USR_PREF.SRV NOT IN (SELECT SEC_ENTITY_FOR_USR_ACTION_VIEW.ENTITYT_ID
FROM SEC_ENTITY_FOR_USR_ACTION_VIEW
WHERE SEC_ENTITY_FOR_USR_ACTION_VIEW.USR_ID = 1
AND SEC_ENTITY_FOR_USR_ACTION_VIEW.ENTITYTYP_CODE = 2
AND USR_PREF.DEVICE IS NULL)
OR (USR_PREF.DEVICE NOT IN (SELECT SEC_ENTITY_FOR_USR_ACTION_VIEW.ENTITYT_ID
FROM SEC_ENTITY_FOR_USR_ACTION_VIEW
WHERE SEC_ENTITY_FOR_USR_ACTION_VIEW.USR_ID = 1
AND SEC_ENTITY_FOR_USR_ACTION_VIEW.ENTITYTYP_CODE = 3)))))
The select query returns the desired rows, but the DELETE command just deletes that entire table.
Please assist.
Your where clause WHERE EXISTS (SOME QUERY) is the problem here. You are basically saying "Delete everything if this subquery returns even one result".
You need to be more explicit. Perhaps something like:
DELETE FROM USR_PREF
WHERE USR_FIELD IN (
SELECT USR_FIELD
FROM USR_PREF
WHERE USR_PREF_T.USER_ID=1
AND ((USR_PREF.SRV NOT IN ...
and so on... With this, only records that match records returned in your subquery will be deleted.
