I need a join table from table 1 and table 2 and be able to apply updates on it so here's my SQL:
select
table1.ackode, tabble1.ket,
table1.debet, table1.kredit,
(select table2.ket from table2
where table2.kode = table1.ackode
and table2.ptlokasi = table1.ptlokasi) as x
from table1;
This resulted in a dbgrid like this :
now, whenever I click on ackode column, it'll open another form which I can select data from it. I wanted ACKODE and X column changed according to data values I've selected in that new form. However, it raised error as X column cannot be written.
is there any idea how to make it possible? I've set the X column's readonly property to false, however no such luck.
Thanks.

I have a table(ENTITY) that needs to be updated based on an ID(FUNNCODE) but the ID(FUNNCODE) is linked between two other tables(from JOINT then to POSITION)
and is independent of where the data is at(table NEORSD). The only parameter I can bind is the position name between the NEORSD table and POSITION table. When I place my LIKE statement into the where clause I get an error in return. If anyone can point me in the right direction it would be greatly appreciated!
Tables:
NEORSD: Contains the range information and 'position name(= Tag_No)'
ENTITY: Needs to update and accept the range information (Holds FUNCCODE)
JOINT: Holds FUNCCODE(named POSFUNCCODE) and corresponding POSCODE
POSITION: Contains POSCODE and 'position name(=POSID)'
UPDATE ENTITY
SET
RANGE0 = (
SELECT RANGE0
FROM NEORSD_1199
WHERE Tag_No like ('%PIT%'))
WHERE
FUNCCODE = (
SELECT POSFUNCCODE
FROM JOINT
WHERE POSCODE = (
SELECT POSCODE
FROM POSITION
WHERE POSID like ('%PIT%'))
If NEORSD_1199 has more than one row with a tag_no like '%PIT%', which NEORSD_1199.RANGE0 value should it use to update ENTITY.RANGE0?
This is the db engine's problem with your SQL.
To better understand, read the SQL backwards:
First you're getting a list of every Position Code from the POSITION table where the Position ID is like '%PIT%'. That might be one code, and it might be one hundred codes.
Then you're getting every Position Function Code from the JOINT table where the Position Code is in the list of Position Codes you just gathered. Again, could be one, could be a hundred.
Then you're getting a list of all values of RANGE0 from the NEORSD1199 table where Tag_No is like '%PIT%'. Again, this could be one value, or a list of one hundred.
Then, you're getting every row from the ENTITY table where the Function Code is in the list of Position Function Codes you gathered from the JOINT table (step 2 above), and you're updating RANGE0 in each of these rows to the value you captured in step 3.
The problem is that the 'value' returned in step 3 could be a list of values. If
NEORSD1199 has four rows where tag number is like '%PIT%'
(e.g. PIT01,PIT02,PIT03,APIT00), and each of those rows has a different
RANGE0 (e.g. 1,2,3,99), then which of those four values should the DB engine use to update RANGE0 in the rows in the ENTITY table?
Thank you to #SQLCliff for the questions that help to find the solution. I created an ID column inside my NEORSD table, created a temporary table holding the link between FUNCCODE and the ranges in NEORSD. Then I updated ENTITY using a join on. I can insert the where clause at the end of the temporary table for filtering if needed. Since it is a mass update I no longer require a where clause. My brain just likes making things more complicated than they need to be XD
with t as(
select f.funccode as funccode ,n.range0, n.range100
from func as f
join NEORSD_1199_With_Ranges_Updated as n on n.id = f.poscode or n.id =f.devcode
/* WHERE nessecrary ;P*/)
update entity
set
range0 = t.range0,
range100 = t.range100
from entity as e
join t on e.funccode = t.funccode
I've created a SELECT query to return all of the records from my table WHERE FieldCount = 3.
I'd now like to append the result of this query to the same table with a new value of FieldCount.
How would you go about appending the results of a query to a table and altering the value of a field?
WHERE and SELECT clause are independent of each other. You can do it like this:
INSERT INTO myTable (foo, bar, FieldCount)
SELECT foo, bar, 77 As FieldCount
FROM myTable
WHERE FieldCount = 3
Create a new Query and base it off the query you just created off that table.
Make sure that the new query is an append query
Add all the fields to the query in design mode
For the new "FieldCount" number, Just place whatever number you want them all to be in the field combobox.
Notice the number 3 is the value I chose to add to the table.
Edit: Andre beat me to it, but his method is easier unless you prefer the GUI way of doing it.
this query is working fine.
UPDATE data
SET unit_id='a3110a89'
WHERE unit_id='7d18289f';
Now, I need to run this query over 30 times
so I made csv file import it to the DB with this command:
COPY mytable FROM 'D:/test.csv' WITH CSV HEADER DELIMITER AS ','
Now I have table called my table with 2 columns OLD and NEW
i want to search the table "data" in column unit_id anywhere there if the value equals to the value in table "mytable.old" replace it with the value "mytable.new" on the same row.
I tried to run this query but I get an error:
UPDATE data
SET unit_id=(SELECT mytable."old" FROM public.mytable)
WHERE unit_id=(SELECT mytable."new" FROM public.mytable)
error:
more than one row returned by a subquery used as an expression
I think i'm just trying to do it in the wrong way...
thx for the help!
by the way Im using PostgreSQL
Your subqueries need to be correlated to the outer update:
UPDATE data
SET unit_id = (SELECT mytable."new" FROM public.mytable where data.old = mytable.old)
WHERE unit_id in (SELECT mytable."old" FROM public.mytable);
That is, set the unit_id to the "new" value, when you find the "old" value in the table.
Can you try like this,
UPDATE data A
SET A.unit_id=B.old
FROM (SELECT mytable."old",mytable."new" FROM public.mytable) B
WHERE A.unit_id=B.new
UPDATE data A
SET unit_id = B."old"
FROM public.mytable B
WHERE A.unit_id = B."new"
;
BTW: it looks like you also have old and new swapped in your question. Do you really want A's value to be set to B's old field?
Sorry for the long question/post but need some help as I've been searching for several days but havent found anything that helps. Seems like it should be easy but..here goes
I have table1 in my (Access 2010) database that has exising records. I have another table2 that after I run a query, it first deletes the data in table 2, then imports new records into that table. I run the import into table 2 on a semi regular basis but have yet to copy all those records into table 1 successfully.
I need to copy only the records from table 2 to table 1 if the records don't already exist in table1. So, each time the query or vba code would run, it would be continuing to grow table 1 without duplicating existing data.
To clarify further, it's data from the Outlook GAL so each time table2 imports that data (lname,fname,phone,email) it needs to be added to table1, but only if it doesn't already exist in table 1.
I have a small start of SQL but cannot get it to work properly because I'm not sure how to add the other fields into this SQL statement properly (unfortunately I don't know a whole lot about SQL or creating an append query):
INSERT INTO [Current] ( FirstName )
SELECT DISTINCT tblglobaladdresslistimport.First
FROM tblglobaladdresslistimport LEFT JOIN [Current] ON tblglobaladdresslistimport.First = Current.FirstName
WHERE Current.FirstName Is Null;
How about this :
INSERT INTO [Current](FirstName, LastName, Phone, Email)
SELECT DISTINCT
tblglobaladdresslistimport.First
, tblglobaladdresslistimport.Last
, tblglobaladdresslistimport.Phone
, tblglobaladdresslistimport.Email
FROM
tblglobaladdresslistimport LEFT JOIN [Current]
ON tblglobaladdresslistimport.First = Current.FirstName
AND tblglobaladdresslistimport.Last = Current.LastName
AND tblglobaladdresslistimport.Phone = Current.Phone
AND tblglobaladdresslistimport.Email = Current.Email
WHERE Current.FirstName Is Null
AND Current.LastName Is Null
AND Current.Phone Is Null
AND Current.Email Is Null;
Adjust column names if I guessed it wrong. That assumed that you don't have primary key, so data in tblglobaladdresslistimport considered already exists if there is a row in Current having same value for all columns.
I want to make filtration on a column after selecting a specific value of another column in the same table, I tried to use #... special character followed by the column's name to get the address of this value.
My SQL statement is like the following :
SELECT ATTRIBUTE FROM TABLE WHERE FIELD = '#FIELDNAME';
If I used a specific value instead of #FIELDNAME, it will work properly but it will be static but I need it to be dynamic based on the selected value.
Create another table which will have the list of values that are in the FIELDNAME and give each record a unique id ,then retrieve the value depending on what you have selected by the name of the new table's field preceded by '#...'
I don't know if that what are you looking for, please let me know.
If no triggers are allowed, do you have any date/time column in the table? Is it possible to have that extra column anyway to see the time of a newly inserted row?
You may have to check the lastest row entered, save its field value into a variable. Then do the select based on the variable value.
Based on the vague last row id you could try the following (it's not pretty). But again, if you have date/time that's more accurate.
select attribute from table
where field = (select field from table
where rowid =(select max(rowid) from table))
;
upate
Do you have the priviledge to set up your insert command as below:
insert into table (id, col1, col2,...) values (1,'something', 'something',...)
returning id into variable; -- you may either save field or id depending on your table
Then you may use this variable to select the records you want.
