We are attempting to update the LastUpdateDateTime column to the value of the Stamp column in another database, on another server via this query:
update [NEWTON-DB].NEWTON.dbo.vital_signs
set lastupdatedatetime =
coalesce ((select top 1 stamp
from [SERVER2].NEWTON.dbo.vital_sign
where rowguid in (select oldrowguid
from [NEWTON-DB].NEWTON.dbo.import_log
where tablename = 'vital_sign'
and newid = [NEWTON-DB].NEWTON.dbo.vital_signs.id)),
coalesce(lastupdatedatetime, getutcdate()))
The import_log table is simply the inner join to fetch the new id based off the old rowguid if that makes any sense.
When they were on the same server this query worked fine, but after migrating I get the following error:
The multi-part identifier "NEWTON-DB.NEWTON.dbo.vital_signs.id" could not be bound.
Is there something blindingly obvious we're missing. Thanks so much in advance!
5 Part identifers like this [NEWTON-DB].NEWTON.dbo.vital_signs.id don't work
You need to alias the table and then use the alias
e.g.
Select top 1 stamp
from [SERVER2].NEWTON.dbo.vital_sign t
where rowguid in (select oldrowguid
from [NEWTON-DB].NEWTON.dbo.import_log
where tablename = 'vital_sign'
and newid = t.id)

I am looking for an alternative for this query. I know that such query will end up with invalid identifier in Oracle. So please give me the same query for updating one filed from another field in another table.
update RBT_CMP_RECOM_9304
set FIRST_RECOM_NAME=(select rbt_cmp_base_code.RBT_NAME
from rbt_cmp_base_code
where rbt_cmp_base_code.RBT_CODE=RBT_CMP_RECOM_9304.FIRST_RECOM)
where rbt_cmp_base_code.RBT_CODE=RBT_CMP_RECOM_9304.FIRST_RECOM;
FYI:
RBT_CMP_RECOM_9304=(firt_recom,first_recom_name)
RBT_CMP_BASE_CODE = (rbt_code, rbt_name)
I get this error when I try it:
ORA-00904: RBT_CMP_BASE_CODE.RBT_CODE: invalid identifier
Regards.
One way is to repeat the subquery:
update RBT_CMP_RECOM_9304 r
set FIRST_RECOM_NAME = (select bc.RBT_NAME
from rbt_cmp_base_code bc
where bc.RBT_CODE = r.FIRST_RECOM
)
where exists (select 1
from rbt_cmp_base_code bc
where bc.RBT_CODE = r.FIRST_RECOM
);
EDIT:
If you are getting an error that more than one row is returned, then you have to decide which value. Nothing in your code suggests that this might be an issue (hint: sample data and desired results always help a question).
The easiest solution is to use and aggregation function:
update RBT_CMP_RECOM_9304 r
set FIRST_RECOM_NAME = (select max(bc.RBT_NAME)
from rbt_cmp_base_code bc
where bc.RBT_CODE = r.FIRST_RECOM
)
where exists (select 1
from rbt_cmp_base_code bc
where bc.RBT_CODE = r.FIRST_RECOM
);
But you might want to fix the rbt_cmp_base_code table so it doesn't have duplicates. From the table name, it sounds like there should be one row per code.
I have a small access database with some tables. I am trying the code in the sql design within access. I just want to randomly select a record within a table.
I created a simple table called StateAbbreviation. It has two columns: ID and Abbreviation. ID is just an autonumber and Abbreviation are different abbreviations for states.
I saw this thread here. So I tried
SELECT Abbreviation
FROM STATEABBREVIATION
ORDER BY RAND()
LIMIT 1;
I get the error Syntax error (missing operator) in query expresion RAND() LIMIT 1. So I tired RANDOM() instead of RAND(). Same error.
None of the others worked either. What am I doing wrong? Thanks.
Ypercude provided a link that led me to the right answer below:
SELECT TOP 1 ABBREVIATION
FROM STATEABBREVIATION
ORDER BY RND(ID);
Note that for RND(), I believe that it has to be an integer value/variable.
You need both a variable and a time seed to not get the same sequence(s) each time you open Access and run the query - and to use Access SQL in Access:
SELECT TOP 1 Abbreviation
FROM STATEABBREVIATION
ORDER BY Rnd(-Timer()*[ID]);
where ID is the primary key of the table.
Please try this, it is helpful to you
It is possible by using a stored procedure and function, which I created it's have a extra column which you could be create in your table FLAG name and column all field value should be 0 Then it works
create Procedure proc_randomprimarykeynumber
as
declare #Primarykeyid int
select top 1
#Primarykeyid = u.ID
from
StateAbbreviation u
left join
StateAbbreviation v on u.ID = v.ID + 1
where
v.flag = 1
if(#Primarykeyid is null )
begin
UPDATE StateAbbreviation
SET flag = 0
UPDATE StateAbbreviation
SET flag = 1
WHERE ID IN (SELECT TOP 1 ID
FROM dbo.StateAbbreviation)
END
ELSE
BEGIN
UPDATE StateAbbreviation
SET flag = 0
UPDATE StateAbbreviation
SET flag = 1
WHERE ID IN (#Primarykeyid)
END
SET #Primarykeyid = 1
SELECT TOP 1
ID, Abbreviation
FROM
StateAbbreviation
WHERE
flag = 1
It is made in stored procedure run this and get serial wise primary key
exec proc_randomprimarykeynumber
Thanks and regard
Try this:
SELECT TOP 1 *
FROM tbl_name
ORDER BY NEWID()
Of course this may have performance considerations for large tables.
I've tried searching for this particular topic here, but haven't found the answer... Anyway, my aim is to update table (let's call it t_item), specifically column owner_id with values depending on another table (t_item_geo which is in turn linked to t_geo).
I'm not entirely sure whether the syntax below is actually valid for update statements.
UPDATE t_item SET owner_id= 6993 WHERE t_item.owner_id in
(SELECT t_item.owner_id FROM
t_item,
t_item_geo,
t_geo
WHERE
t_item.id = t_item_geo.item_id and
t_item_geo.geo_id = t_geo.id and
t_item.owner_id in (SELECT id FROM t_user WHERE network_id='fffffff') and
t_geo.id in (SELECT id FROM t_geo WHERE full_name = 'yyyyyyy')
);
Anyway, my problem with this query is that it updates far more rows than it should - if I separate just the select statement Oracle returns ~750 rows but the udpate itself updates more than 4000 rows. It's almost as if the condition was completely ignored - which would point me to perhaps incorrect syntax.
I need to update specific value in the table based on the select from few other 'joined' tables. Hope it makes sense.
Thanks for any contribution!
UPDATE: sorry - maybe it wasn't clear from the question itself, but the correct number of edited items should be ~750 and not ~4000. Thanks!
try this
MERGE INTO t_item
USING
(
SELECT t_item.owner_id FROM
t_item,
t_item_geo,
t_geo,
t_item.rowid rowid_sub
WHERE
t_item.id = t_item_geo.item_id and
t_item_geo.geo_id = t_geo.id and
t_item.owner_id in (SELECT id FROM t_user WHERE network_id='fffffff') and
t_geo.id in (SELECT id FROM t_geo WHERE full_name = 'yyyyyyy')
) on (rowid = rowid_sub)
WHEN MATCHED THEN
UPDATE SET owner_id= 6993;
I've been trying for a few hours (probably more than I needed to) to figure out the best way to write an update sql query that will dissallow duplicates on the column I am updating.
Meaning, if TableA.ColA already has a name 'TEST1', then when I'm changing another record, then I simply can't pick a value for ColA to be 'TEST1'.
It's pretty easy to simply just separate the query into a select, and use a server layer code that would allow conditional logic:
SELECT ID, NAME FROM TABLEA WHERE NAME = 'TEST1'
IF TableA.recordcount > 0 then
UPDATE SET NAME = 'TEST1' WHERE ID = 1234
END IF
But I'm more interested to see if these two queries can be combined into a single query.
I am using Oracle to figure things out, but I'd love to see a SQL Server query as well. I figured a MERGE statement can work, but for obvious reasons you can't have the clause:
..etc.. WHEN NOT MATCHED UPDATE SET ..etc.. WHERE ID = 1234
AND you can't update a column if it's mentioned in the join (oracle limitation but not limited to SQL Server)
ALSO, I know you can put a constraint on a column that prevents duplicate values, but I'd be interested to see if there is such a query that can do this without using constraint.
Here is an example start-up attempt on my end just to see what I can come up with (explanations on it failed is not necessary):
ERROR: ORA-01732: data manipulation operation not legal on this view
UPDATE (
SELECT d.NAME, ch.NAME FROM (
SELECT 'test1' AS NAME, '2722' AS ID
FROM DUAL
) d
LEFT JOIN TABLEA a
ON UPPER(a.name) = UPPER(d.name)
)
SET a.name = 'test2'
WHERE a.name is null and a.id = d.id
I have tried merge, but just gave up thinking it's not possible. I've also considered not exists (but I'd have to be careful since I might accidentally update every other record that doesn't match a criteria)
It should be straightforward:
update personnel
set personnel_number = 'xyz'
where person_id = 1001
and not exists (select * from personnel where personnel_number = 'xyz');
If I understand correctly, you want to conditionally update a field, assuming the value is not found. The following query does this. It should work in both SQL Server and Oracle:
update table1
set name = 'Test1'
where (select count(*) from table1 where name = 'Test1') > 0 and
id = 1234
This is one annoying issue and I can't figure out how to solve it. I'm Using Microsoft SQL Server 2008.
So I have two tables and I need to update both of them. They share a common key, say id. I want to update Table1 with some stuff and then update the Table2 rows which were respectively modified in Table1.
The issue is that I don't quite know which rows were modified, because I'm picking them randomly with ORDER BY NEWID() so I probably cannot use a JOIN on Table2 in any way. I am trying to save the necessary details which were modified in my query for Table1 and pass them to Table2
This is what I'm trying to do
CREATE TABLE IDS (id int not null, secondid int)
SELECT [Table1].[id], [Table1].[secondid]
INTO IDS
FROM
(
UPDATE [Table1]
SET [secondid]=100
FROM [Table1] t
WHERE t.[id] IN
(SELECT TOP 100 PERCENT t.[id] FROM [Table1]
WHERE (SOME_CONDITION)
ORDER BY NEWID()
)
)
UPDATE [Table2]
SET some_column=i.secondid
FROM [Table2] JOIN IDS i ON i.id = [Table2].[id]
But I get
Incorrect syntax near the keyword 'UPDATE'.
So the question is: how can I solve the syntax error or is it a better way to do this?
Note: the query enclosed between the parentheses of the first FROM worked well before this new requirement, so I doubt there's a problem in there. Or maybe?
EDIT: Changing the second UPDATE as skk suggested still leads to the same error (on exactly the below line which contains UPDATE):
UPDATE [Table2]
SET some_column=i.secondid
FROM [Task] JOIN IDS i on i.[id]=[Table2].[id]
WHERE i.id=some_value
Instead of creating a new table manually, SQL server has the OUTPUT clause to help with this
It's complaining because you aren't aliasing the derived table used in the first query, immediately preceding UPDATE [Table2].
If you add an alias, you'll get a different error:
A nested INSERT, UPDATE, DELETE, or MERGE statement must have an OUTPUT clause.
Which leads back to #Adam Wenger's answer.
Not sure I completely understand what you are trying to do, but the following sql will execute (after replacing SOME_CONDITION):
CREATE TABLE IDS (id int not null, secondid int)
UPDATE t SET [secondid] = 100
OUTPUT inserted.[id], inserted.[secondid] into [IDS]
FROM [Table1] t
WHERE t.[Id] IN
(
SELECT TOP 100 PERCENT t.[id] from [Table1]
WHERE (SOME_CONDITION)
ORDER BY NEWID()
)
UPDATE [Table2]
SET some_column = i.secondid
FROM [Table2] JOIN IDS i ON i.id = [Table2].[id]
The Update syntax is as follows
UPDATE TableName SET ColumnName = Value WHERE {Condition}
but you have used FROM keyword also in that.
EDIT:
You change the code like follows and try again
UPDATE [Table2] SET some_column=IDS.secondid WHERE IDS.[id] = [Table2].[id] and
IDS.id=some_value
