I imported an e-store's database values into my own, and it mostly worked out fine. However, there were no image file names. So, I need to update the entire database- over 6,000 records, so that under 'image' we get a path + model name + jpg, so each product can be associated with an image. Im having trouble mixing the dynamic column value with the static path. Here is what I need to accomplish:
UPDATE `store`.`pr_product`
SET `image` = 'data/products/`**model_no**`.jpg'
WHERE `pr_product`.`product_id` = `pr_product`.`product_id` ;
But cannot get it to recognize the dynamic nature of 'model_no'
Thanks in advance
Max,
Please what you means about dynamic nature of 'model_no'?
Is this column's datatype int or long or varchar
Please need more explaination with example
you can test the following if e.g model_no is column in pr_product table
UPDATE store.pr_product
SET image = 'data/products/'+pr_product.model_no+'.jpg'
WHERE pr_product.product_id = pr_product.product_id ;
Best Regards,

I have a table T with a column J of type json, and one of it's row contains value
{'SELECTION':'A'}
I want to change it to
{'selection':'A'}
i.e change the key of the JSON.
Any one has experience? I am not able to find any relevant resource.
Thanks to #Sebastian, I solved it using the documentation https://www.postgresql.org/docs/current/functions-json.html
update T set J = '{"selection":"A"}' where J::jsonb #> '{"SELECTION":"A"}'::jsonb
Another query that will do same
update T set J = '{"selection":"A"}' where J::json->>'SELECTION'='A'
I have a requirement where I need to change the order in which records are printed in a Report. I need to order the records by a substring of a field of the records.
There is an OPNQRYF as below before the call to the report RPG is made:
OVRDBF FILE(MOHDL35) SHARE(*YES)
BLDQRYSLT QRYSLT(&QRYSLT) +
SELECT((CHARDT *GE &FRDATE F2) +
(CHARDT *LE &TODATE F2) +
(HDPLVL *EQ 'FS' F2) +
(HDMPLT *EQ &PLANT F2))
OPNQRYF FILE((*LIBL/MOHDL35)) +
QRYSLT(&QRYSLT) +
KEYFLD(*FILE) +
MAPFLD((ZONEDT HDAEDT *ZONED 8 0) +
(CHARDT ZONEDT *CHAR 8))
One way I see how to do this is to do a RUNSQL to create a temp table in qtemp with the MOHDL35 records in the required order. The substr SQL function would help to achieve this much easier. This should have the same structure as that of MOHDL35 (FIELD NAMES, RECORD FORMAT)
Then replace the use of this file in the RPG program with the newly created table name. I havent tried this yet, but would this work? does it sound like a good idea? Are there any better suggestions?
You can do that with OPNQRYF by using the MAPFLD parameter like this:
OPNQRYF FILE((JCVCMP))
KEYFLD((*MAPFLD/PART))
MAPFLD((PART '%SST(VCOMN 2 5)'))
The fields in JCVCOMN are now sorted like this:
VENNO VCMTP VCMSQ VCOMN
----- ----- ----- -------------------------
1,351 ICL 3 Let's see what wow
1,351 ICL 1 This is a test
1,351 NDA 2 another comment
1,351 NDA 1 more records
Notice that the records are sorted by the substring of VCOMN starting with the second character.
So here is your OPNQRYF with multiple key fields specified
OPNQRYF FILE((*LIBL/MOHDL35))
QRYSLT(&QRYSLT)
KEYFLD((*MAPFLD/CHARDT) (*MAPFLD/HDPROD))
MAPFLD((ZONEDT HDAEDT *ZONED 8 0) (CHARDT ZONEDT *CHAR 8)
(HDPROD '%SST(HDPROD 1 2) *CAT %SST(HDPROD 10 12)
*CAT %SST(HDPROD 13 16)'))
Some notes: I am guessing that HDAEDT is a PACKED number. If so, you don't need to map it to a ZONED number just to get it to a character value. If you need the ZONED value, that is ok (but PACKED should work just as well). Otherwise, you can just use:
MAPFLD((CHARDT HDAEDT *CHAR 8))
Also in your OVRDBF, you need to make sure you choose the correct Override Scope OVRSCOPE. The IBM default is OVRSCOPE(*ACTGRPDFN). OPNQRYF also has a scope OPNSCOPE. You need to make sure that the OVRSCOPE, the OPNSCOPE, and the program using the table all use the same activation group. There are a lot of different combinations. If you can't make it work, you can always change them all to *JOB, and that will work. But there is nothing intrinsic about OPNQRYF that prevents it from working from a CLP.
I would try creating a view with all the table fields plus the substring'd column, and then use OPNQRYF with that instead of the table, specifying the substring'd column as the KEYFLD. That would probably be simpler (& potentially quicker) than copying the whole lot into QTEMP every time.
I've just started using microsoft access so I don't really know how to solve this. I would like to use an update query to add a value from a form to a value on a table.
I originally used the SUM expression which gave me an error saying it was an aggregate function.
I also tried to add the two values together (e.g [field1] + [field2]) which as a result gave me a value with both numbers together instead of adding them together.
The following is the SQL I'm using:
UPDATE Votes
SET Votes.NumVotes = [Votes]![NumVotes]+[Forms]![frmVote]![txtnumvotes]
WHERE (((Votes.ActID) = [Forms]![frmVote]![combacts])
AND ((Votes.RoundNum) = [Forms]![frmVote]![combrndnum]))
I want to add a value [txtnumvotes] a form to a field [NumVotes] from the table [Votes].
Could someone please help me?
You can specify the expected data type with parameters:
PARAMETERS
[Forms]![frmVote]![txtnumvotes] Short,
[Forms]![frmVote]![combacts] Long,
[Forms]![frmVote]![combrndnum] Long;
UPDATE
Votes
SET
Votes.NumVotes = [Votes]![NumVotes]+[Forms]![frmVote]![txtnumvotes]
WHERE
(((Votes.ActID) = [Forms]![frmVote]![combacts])
AND
((Votes.RoundNum) = [Forms]![frmVote]![combrndnum]))
Without the specification, Access has to guess, and that sometimes fails.
I have a table that has a column called RAW DATA of type NVARCHAR MAX, which is a dump from a web service. Here is a sample of 1 data line:

It was suppose to go in a table, with the node names representing the column names. The table it's going to is created, I just need to exract the data from this row to the table. I have 100's of thousands records like this. I was going to copy to a xml file, then import. But there is so much data, I would rather try and do the work within the DB.
Any ideas?
First, create the table with all the required columns.
Then, use your favorite scripting language to load the table! Mine being groovy, here is what I'd do:
def sql = Sql.newInstance(/* SQL connection here*/)
sql.eachRow("select RAW_DATA from TABLE_NAME") { row ->
String xmlData = row."RAW_DATA"
def root = new XmlSlurper().parseText(xmlData)
def date = root.eventDate
def histSeqNo = root.histSeqNo
//Pull out all the data and insert into new table!
}
I did find an answer to this, I'm sure there is more than one way of doing this. But this is what I got to work. Thanks for everyone's help.
SELECT
pref.value('(caseNo/text())[1]', 'varchar(20)') as CaseNumber,
pref.value('(countyNo/text())[1]', 'int') as CountyNumber
FROM
dbo.CaseHistoryRawData_10 CROSS APPLY
RawData.nodes('//CourtRecordEventCaseHist') AS CourtRec(pref)
I'm a novice in mySql.
I'm trying to replace a value in the xml column of my table.
my select method works.
SELECT * FROM `comics` WHERE ExtractValue(xml,'comic/pageNumber') = 6
my replace method doesn't. I've been searching for the correct syntax for a bit now...
SET xml.modify(
replace value of ('comic/pageNumber') with 5
)
some background:
this situation comes up when i delete a comic page.
it leaves a gap in the page numbers, after which i would either:
iterate through all the comics and remove any gaps in the page numbers.
or
iterate through all comics with pageNumber larger than the deleted page, and reduce their pageNumber by 1.
How about
UPDATE comics
SET xml = UpdateXML(xml,'comic/pageNumber', '<pageNumber>5</pageNumber>')
WHERE ExtractValue(xml,'comic/pageNumber') = 6
Tested on MySQL version 5.1
UPDATE `comics`
SET xml = UpdateXML(xml,
'comic/pageNumber',
concat('<pageNumber>',(ExtractValue(xml,'comic/pageNumber')+1),'</pageNumber>'))
WHERE ExtractValue(xml,'comic/pageNumber') >= 1
You'd be better off actually storing the fields in the table, rather than a single field with xml in it. Then the following would work. Otherwise there's not much point using a relational database at all.
BEGIN;
DELETE FROM `comics`
WHERE `comicID` = :id AND `pageNumber` = :page;
UPDATE `comics` SET `pageNumber` = `pageNumber` - 1
WHERE `comicID` = :id AND `pageNumber` > :page;
COMMIT;
