IF EXISTS(SELECT * FROM MERC_ADM_VERSION )then UPDATE MERC_ADM_VERSION SET
VER_VALEUR = 20150409 WHERE VER_CLE = 'MEAD' ELSE INSERT INTO MERC_ADM_VERSION
('VER_VALEUR', 'VER_CLE') VALUES (20150409, 'MEAD');
ORA-00900: Invalid SQL statement
Remove the single quotes from the columns in the insert statement.
Instead of
('VER_VALEUR', 'VER_CLE')
It should be
(VER_VALEUR, VER_CLE)
Your question is quite unclear as to what you are trying to do. However, my best interpretation is you are looking for an oracle merge statement. Below is an example based on assumptions I made on the little information you provided. You are most likely looking for a MERGE statement. This allows you to perform a single operation that can either update or insert based on your criteria.
Also, you appear to be using a date, but in number format. I did nothing to address this due to lack of any table definition. You may still have problems with it.
MERGE
INTO merc_adm_version TARGET -- The table you want to update/insert into
USING (SELECT 20150409 as ver_valeur, 'MEAD' as ver_cle FROM dual) SOURCE -- The source of the data
ON (TARGET.ver_cle = SOURCE.ver_cle) -- How to try and match records between source and target
WHEN MATCHED THEN UPDATE SET ver_valeur = 20150409 -- When there is a match, how to update
WHEN NOT MATCHED THEN INSERT (ver_cle, ver_valeur) -- When there is not a match, how to insert
VALUES ('MEAD', 20150409);

I am new to BigQuery and was wondering if there was a way to search for a specific row, then individually update its columns using a Query. I am very new to database and SQL, and would love some of your help.
Yes you can. Typically this is achieved through data manipulation language (DML). For this specific example you would want use an UPDATE statement.
Documentation on this can be found here:
https://cloud.google.com/bigquery/docs/reference/standard-sql/dml-syntax#update_statement
As a word of caution verify your where clause before you execute to ensure you are targeting the correct rows.
For example:
UPDATE your_table
SET assigned_to_user = 'updated_value' -- the value you want to update to
WHERE -- this is where you define your criteria to narrow down to a subset of rows
criteria_column = 'target_values' -- this is your critera
-- and criteria_column_2 = 'other_value' -- if you need to expand more critiera just use logic operators like `and` or `or`
You can also test out what will be updated by issuing a select statement with the same criteria as your update and seeing which columns come back, for example:
select *
from your_table
WHERE
criteria_column = 'target_values'
I am doing a simple insert and am stumped, I'm new to oracle and unsure of what the issue is. I don't have the table structure so I am guessing that most of the fields are character except the dates.
Anyway here is my query, can anyone find the issue?
INSERT INTO PHANTOM_BOXES (CARRIER_CODE,CARRIER_TRACKING_NO,SENT_DATE,SEND_COST,
RECEIVED_DATE,REC_COST, COMMENTS,SHIPPING_TECH,RECEIVING_TECH)
VALUES ('1','11',TO_DATE('2016-02-04','YYYY-MM-DD'),'1',
TO_DATE('2016-02-04','YYYY-MM-DD'),'1','1','26437','0')
WHERE BOX_NO = '6738'
NO where dude.what is ther where for.
INSERT INTO PHANTOM_BOXES (CARRIER_CODE,CARRIER_TRACKING_NO,SENT_DATE,SEND_COST,
RECEIVED_DATE,REC_COST, COMMENTS,SHIPPING_TECH,RECEIVING_TECH,BOX_NO)
VALUES ('1','11',TO_DATE('2016-02-04','YYYY-MM-DD'),'1',
TO_DATE('2016-02-04','YYYY-MM-DD'),'1','1','26437','0','6738')
WHERE BOX_NO = '6738'
INSERT statement cannot have a WHERE clause, makes no sense.
Simply do INSERT INTO..VALUES:
INSERT INTO PHANTOM_BOXES (CARRIER_CODE,CARRIER_TRACKING_NO,SENT_DATE,SEND_COST,
RECEIVED_DATE,REC_COST, COMMENTS,SHIPPING_TECH,RECEIVING_TECH)
VALUES ('1','11',TO_DATE('2016-02-04','YYYY-MM-DD'),'1',
TO_DATE('2016-02-04','YYYY-MM-DD'),'1','1','26437','0')
Where Clause is used for filter and applying condition Rows which were already present in Table.
Seems you are trying to update the values for WHERE BOX_NO = '6738'
For this you have to use Update Statement
Update PHANTOM_BOXES
Set CARRIER_CODE='1',
CARRIER_TRACKING_NO='11',
SENT_DATE=TO_DATE('2016-02-04','YYYY-MM-DD'),
SEND_COST='1',
RECEIVED_DATE=TO_DATE('2016-02-04','YYYY-MM-DD'),
REC_COST='1',
COMMENTS,SHIPPING_TECH='26437',
RECEIVING_TECH='0';
Consider the following:
merge into T t1
using (select ID,Col1 from T where ID = 123) t2
on 1 = 0
when not matched then insert (Col1) values (t2.Col1);
Cominig from a programming background, to me this translates to:
"Evaluate false (i.e. 1 = 0), and when it is false (i.e. all the time), insert."
Is it not possible to just omit the match condition?
Is it because of my select's where condition that I'm confused here? Should this condition be moved to the on?
NOTE:
Due to restrictions with output, I cannot use insert. I need to output the results of this merge into a temporary table for reasons outside of the scope of what I'm asking.
In the answer you've linked to in the comments, as I've hopefully made clear, we are abusing the MERGE statement.
The query you've shown here could trivially be replaced by:
insert into T(Col1) select Col1 from T where ID = 123
However, if you want to be able to add an OUTPUT clause, and that OUTPUT clause needs to reference both the newly inserted data and data from the source table, you're not allowed to write such a clause on an INSERT statement.
So, we instead use a MERGE statement, but not for its intended purpose. The entire purpose is to force it to perform an INSERT and write our OUTPUT clause.
If we examine the documentation for MERGE, we see that the only clause in which we can specify to perform an INSERT is in the WHEN NOT MATCHED [BY TARGET] clause - in both the WHEN MATCHED and WHEN NOT MATCHED BY SOURCE clauses, our only options are to UPDATE or DELETE.
So, we have to write the MERGE such that matching always fails - and the simplest way to do that is to say that matching should occur when 1 = 01 - which, hopefully, is never.

I am using APEX collections to store some values and pass them between pages in Oracle Application Express 4.2.3.
I would like to then perform an update statement on a table called "project" with the values from the collection.
My code so far is as follows:
update project
SET name=c.c002,
description=c.c007,
start_date=c.c004,
timeframe=c.c005,
status=c.c009
FROM
apex_collections c
WHERE
c.collection_name = 'PROJECT_DETAILS_COLLECTION'
and id = :p14_id;
where :p14_id is the value of a page item.
However, I am getting the following error:
ORA-00933: SQL command not properly ended
Anyone have any idea on how to approach this?
Thanks!
The UPDATE syntax you are using is not valid in Oracle; it does not allow you to use FROM in the way you are attempting.
The simplest way to do this in Oracle would with a subquery:
update project
set (name, description, start_date, timeframe, status) =
(select c.c002, c.c007, c.c004, c.c005, c.c009
FROM
apex_collections c
WHERE
c.collection_name = 'PROJECT_DETAILS_COLLECTION'
)
WHERE
id = :p14_id
;
Note that if the subquery returns no rows, the columns in the target table will be updated to NULL; this could be avoided by adding a similar EXISTS condition in the predicate for the update. It could also be avoided by using a MERGE statement instead of an UPDATE.
If the subquery returns multiple rows, the statement will throw an error. It looks like tthat should not be the case here.
I have created a lookup table in Access to provide the possible values for a column. Now I need to update this column with the data it had before I converted the column. I am unable to figure out a SQL Query that will work. I keep getting the error "An UPDATE or DELETE query cannot contain a multi-valued field." My research has suggested that I just need to set the value of the column but this always updates 0 records:
UPDATE [table_name] SET [column_name].Value = 55 WHERE [table_name].ID = 16;
I know this query will work if I change it to update a text column, so it is definitely a problem with just this column.
If you're adding a value to your multi-valued field, use an append query.
INSERT INTO table_name( [column_name].Value )
VALUES (55)
WHERE ID = 16;
If you want to change one particular value which exists in your multi-valued field, use an UPDATE statement. For example, to change the 55 to 56 ...
UPDATE [table_name]
SET [column_name].Value = 56
WHERE [column_name].Value = 55 And ID = 16;
See Using multivalued fields in queries for more information.
I have figured this out! It certainly was counter-intuitive! You have to use an INSERT statement to do the update.
-- Update a record with a multi-valued field that has no value
INSERT INTO [table_name] ( [[column_name].[Value] )
VALUES(55)
WHERE [table_name].ID = 16;
This confused me because I was expecting an UPDATE statement. I think it actually inserts a record into a hidden table that is used to associate multiple values with this column.
I am working with Sharepoint, I created the tables as multi-value fields, ran into the error with my INSERT INTO statement, went back to Sharepoint to change to non-multi-value fields, but that didn't fix it.
Recreated the table without using multi-value fields, and the INSERT INTO worked just fine.
do not use the .value part
UPDATE [table_name] SET [column_name] = 55 WHERE [table_name].ID = 16;
INSERT INTO Quals (cTypes.[value])
SELECT Quals_ContractTypes.ContractType
FROM Quals_ContractTypes
WHERE (Quals.ID = Quals_ContractTypes.ID_Quals);
I gotta say I didn't understand very well your problem but I saw something strange in your query. Try this:
UPDATE [table_name] SET [column_name]= 55 WHERE [table_name].ID = 16;
UPDATE:
Look at this link: it has an example
UPDATE Issues
SET Issues.AssignedTo.Value = 10
WHERE (((Issues.AssignedTo.Value)=6)
AND ((Issues.ID)=8));
NOTES
You should always include a WHERE
clause that identifies only the
records that you want to update.
Otherwise, you will update records
that you did not intend to change. An
Update query that does not contain a
WHERE clause changes every row in the
table. You can specify one value to
change.
The Multi-Valued field refers to Access databases that have tables with columns, that allow you to select multiple values, like a Combo Checkbox list.
THOSE are the only Access types that SQL cannot work with. I've tested all Access lookup possibilities, including hard-coded values, and lookup tables. They work fine, but if you have a column that has the Allow Multiple select options, you're out of luck. Even using the INSERT INTO as mentioned below, will not work as you'll get a similar but different error, about INSERTing into multi-valued fields.
As mentioned it's best to avoid using such tables outside of Access, and refer to a table specifically for your external needs. Then write a macro/vba script to update the real tables with the data from the "auxiliary" table.
