I am attempting to update a field based upon data in a joined table. I've read that the Update command will not work with a table joins in the where clause. However, I cannot use the Exists command workaround as my condition is not the existence of a linked record, but rather a value in that linked record.
update stock S
set stm_auto_key=186086
From
STOCK Left Join
STOCK_RESERVATIONS On STOCK.STR_AUTO_KEY = STOCK_RESERVATIONS.STR_AUTO_KEY
Where
S.QTY_OH > 0 And
S.STM_LOT = 128729 And
STOCK_RESERVATIONS.IND_AUTO_KEY Is Null
The select statement works fine stand alone. However using it in an update command yields "SQL command not properly ended."
Thanks in advance...
I guess, you need something like this, because there might be no FROM clause in UPDATE statement:
update stock S
set stm_auto_key=186086
Where
S.QTY_OH > 0 And
S.STM_LOT = 128729 And
(SELECT STOCK_RESERVATIONS.IND_AUTO_KEY FROM STOCK_RESERVATIONS
WHERE S.STR_AUTO_KEY = STOCK_RESERVATIONS.STR_AUTO_KEY) Is Null

I'm trying to put together a query that updates a field within a table. I'm attempting to run a sub select query that gives me a number, and then use that number that resulted from the sub-query as part of the criteria for the update query.
USE EMMS
Update [2_import_VZW_tbl_SMTN]
set [2_import_VZW_tbl_SMTN].[Client_ID] =[tbl_Foundation_Account].[Client_ID]
where ([tbl_Foundation_Account].[Foundation_Account_ID] =
(Select TOP 1 tbl_Foundation_Account.Foundation_Account_ID
FROM tbl_Foundation_Account
INNER JOIN [2_Import_tbl_AWCDSU]
ON tbl_Foundation_Account.Foundation_Account_ID =
[2_Import_tbl_AWCDSU].[ECPD Profile ID]))
My issue is I keep receiving this error
The multi-part identifier
tbl_Foundation_Account.Foundation_Account_ID" could not be bound.
Am I using the sub-query incorrectly? When I've received this error before, it's been because of some ambiguity in the table or field names, but this time I've checked for all that and it should be fine. Can anyone explain what SQL sin I have committed?
On the error
The multi-part identifier
tbl_Foundation_Account.Foundation_Account_ID" could not be bound.
This is because the table column [tbl_Foundation_Account].[Client_ID] does not exists in the scope of outer UPDATEquery .
The only table the outer query has an inkling about is [2_import_VZW_tbl_SMTN] and it does not have a column like [tbl_Foundation_Account].[Client_ID].
It is akin to writing a column name with a typo or like you said
When I've received this error before, it's been because of some
ambiguity in the table or field names
Please try a query like below.
Note that I am using Inner query syntax and ensuring that a single value is returned by using
select top 1 [Client_ID]
in the inner query. rest of the query syntax is same.
USE EMMS
Update [2_import_VZW_tbl_SMTN]
set [2_import_VZW_tbl_SMTN].[Client_ID] =
(
select top 1 [Client_ID]
from [tbl_Foundation_Account]
where [Foundation_Account_ID] =
(
Select TOP 1 a.Foundation_Account_ID
FROM tbl_Foundation_Account a
INNER JOIN [2_Import_tbl_AWCDSU] b
ON a.Foundation_Account_ID = b.[ECPD Profile ID]
)
)
Another poster submitted this answer earlier, but then deleted it. I was able to try it before they deleted it and it works exactly how I needed it to work. I will use this as the right answer unless someone else can tell me why this is a bad Idea.
USE EMMS
Update [2_import_VZW_tbl_SMTN]
set [2_import_VZW_tbl_SMTN].[Client_ID] = [tbl_Foundation_Account].[Client_ID]
from [tbl_Foundation_Account]
where ([tbl_Foundation_Account].[Foundation_Account_ID] =
(Select TOP 1 tbl_Foundation_Account.Foundation_Account_ID
FROM tbl_Foundation_Account
INNER JOIN [2_Import_tbl_AWCDSU]
ON tbl_Foundation_Account.Foundation_Account_ID = [2_Import_tbl_AWCDSU].[ECPD Profile ID]))
I am trying to update a table using the information that exist from another table. the table that I want to update is called YVDtemp and the second table I am getting the information from is called yvs_textsMain. I also use a 3rd table to match any records that I dont have and this table is called YVD. Here is my update statement.
update Yvdtemp
set
NAME = yvd_textsmain.[name]
SPIC = yvd_textsmain.[rname]
EFFECT = yvd_textsmain.[desc]
where exists (
select yvd_textsMain.[name], yvd_textsMain.[rname], yvd_textsMain.[desc]
from YVD_textsMain
left outer join YVD
on (YVD_textsMain.[rname] = yvd.[spic])
where yvd.[spic] is null);
It seems that this statement is not working. It gives me an error "near 'spic': syntax error
but, when i use use the select statement apart from the update statement the select statement works and I get all the information that is not in YVD table and that information I want to pass it into YVDTemp table.
I am using SQLite.
As there is no matching condition between Yvdtemp and yvd_textsmain how will you map the rows in update statement.
Based on the requirement it looks like you are looking out for an Insert command which can be written as:
INSERT INTO Yvdtemp (NAME, SPIC, EFFECT)
Select yvd_textsMain.[name], yvd_textsMain.[rname], yvd_textsMain.[desc]
from YVD_textsMain
left outer join YVD
on (YVD_textsMain.[rname] = yvd.[spic])
where yvd.[spic] is null
You miss the commas
NAME = yvd_textsmain.[name],
SPIC = yvd_textsmain.[rname],
EFFECT = yvd_textsmain.[desc]
The Problem
I need to write an Update query where my SET references an outer joined table.
I can do this fairly easily with SQL Server but I'm having a heck of a time figuring out the syntax in Oracle as I'm only allow a single table in an update query.
I have written the following Oracle query:
UPDATE SalesExt_tmp tmp
SET slsrep = (SELECT three_dig_rep
FROM dw_sls_rep_conv sls
WHERE sls.aims_rep = tmp.slsrep)
WHERE EXISTS (SELECT three_dig_rep
FROM dw_sls_rep_conv sls
WHERE sls.aims_rep = tmp.slsrep)
AND tmp.sysind = 'AIM';
This takes care of the intersection but I need to deal with values in SalesExt_tmp that do not have equivalent matches in dw_sls_rep_conv (I plan to add a case statement to set null values to a default value). To do this I need to set up dw_sls_rep_conv as an outer joined table. But this is where I get stuck.
SQL Server Example
In SQL Server the solution is a piece of cake as you can have multiple tables in an Update Query:
UPDATE SalesExt_tmp tmp
LEFT JOIN dw_sls_rep_conv sls ON sls.aims_rep = tmp.slsrep
SET tmp.slsrep = sls.three_dig_rep
WHERE tmp.sysind = 'AIM';
But I can't for the life of me figure out how to do this in Oracle. I understand that this query will allow my slsrep field to be set to NULL in some occasions which causes me to fear that this operation may not be allowed.
Questions
1) Firstly is this possible in Oracle? (It's got to be, right?)
2) How do I need to restructure my query to pull this off? I'm guessing my WHERE EXISTS clause needs to go... but I'm still stuck as to where to place my JOIN.
If I understood you correctly, you want to set the value to NULL if there is no match in the dw_sls_rep_conv table? If so, just drop your EXISTS condition and all the rows will be updated:
UPDATE SalesExt_tmp tmp
SET slsrep = (SELECT three_dig_rep
FROM dw_sls_rep_conv sls
WHERE sls.aims_rep = tmp.slsrep)
WHERE tmp.sysind = 'AIM';
If there is a match in the dw_sls_rep_conv table, then the slsrep column will be updated with selected value, otherwise, with NULL.
Have you considered using a subquery in your where clause that performs the outer join as you stated like this:
UPDATE SalesExt_tmp tmp
SET slsrep = (SELECT three_dig_rep
FROM dw_sls_rep_conv sls WHERE sls.aims_rep = tmp.slsrep)
WHERE
tmp.rowid in
(SELECT tmp1.rowid
FROM SalesExt_tmp tmp1,
dw_sls_rep_conv sls
WHERE
tmp1.slsrep = sls.aims_rep (+)
AND tmp1.sysind = 'AIM' );
I am new to SQL and despite hours of searching, cannot figure out the SQL query to update records in my members table, based on conditions in my payments table. I'm very confused whether I use a JOIN (and if so what kind) or a Subquery?
Here's what I have so far:
UPDATE wp_mcra_members
SET wp_mcra_members.dues_paid = 1
JOIN wp_mcra_payments ON wp_mcra_payments.member = wp_mcra_members.ID
WHERE wp_mcra_payments.year_paid = '2013' and wp_mcra_payments.reason = 'Dues';
I want the databased to search for any records in the Payments table that meet my conditions of being year 2013 and labeled Dues. Then I want the Members table to update the field dues_paid based on any found records matching those conditions, where the Member ID = Payments Member
The syntax for an update with a join varies by database. Here is generic syntax using a subquery in the where clause:
UPDATE wp_mcra_members
SET dues_paid = 1
where wp_mcra_members.id in (select wp_mcra_payments.member
from wp_mcra_payments
WHERE wp_mcra_payments.year_paid = '2013' and
wp_mcra_payments.reason = 'Dues'
) ;
The syntax you supplied looks like it would work if you are using SQL Server. Oracle does not support JOINs with UPDATE, instead look into using MERGE or Gordon's answer would also work there.
Assuming however you are using MySQL, a JOIN in the UPDATE statement would probably have a better performance than using IN:
UPDATE wp_mcra_members
JOIN wp_mcra_payments ON wp_mcra_payments.member = wp_mcra_members.ID
SET wp_mcra_members.dues_paid = 1
WHERE wp_mcra_payments.year_paid = '2013'
and wp_mcra_payments.reason = 'Dues';
Could really use some help with an update query...(SQL Serer 2008 R2 Express)
I have two tables, tblJP and tblMaster.
I only have a string field that matches between the two tables.
tblJP AND tblMaster
I need to update tblJP.LangString with tblMaster.Long_text when
tblJP.short_text = tblMaster.short_text AND tblMaster.Lang = 'jp'
Any help would be greatly appreciated. I am spinning my wheels trying all sorts of logic and syntax from creating temp tables to other types of joins all with no luck.
A simple update with an INNER JOIN should do the trick.
UPDATE tblJP
SET tblJP.LangString = tblMaster.Long_Text
FROM tblJP
INNER JOIN tblMaster ON tblMaster.alt_text = tblJP.short_text
WHERE tblMaster.Lang = 'jp'
WARNING: Never run an update statement against your production server without first testing it against a development server - especially when someone else wrote the SQL.
You could also use MERGE
MERGE INTO tblJP
USING (SELECT *
FROM tblMaster
WHERE Lang = 'jp') AS SOURCE
ON SOURCE.alt_text = tblJP.short_text
WHEN MATCHED THEN
UPDATE SET LangString = SOURCE.Long_Text;
In the event that the JOIN returns multiple rows you will be alerted to the problem with an error The MERGE statement attempted to UPDATE or DELETE the same row more than once.
