How to update one column from another table

Hello

We have some sellers who are defined as employees but without employee_id for some reason any. So I would like to update the correct number of a view of HR records. Here is what I tried:

update of po.po_vendors x

Define employee_id = (select apps.per_people_v7 person_id y)

where y.first_name |' '|| y.last_name = x.vendor_name)

Error received: a row subquery returns more than one line.

If I use this instruction to check, I'm correct employee_id or person_id home:

Select apps.per_people_v7 person_id y, po.po_vendors x

where y.first_name |' '|| y.last_name = x.vendor_name

When I checked/compared with some old posts here, I could not just see where I did mistake. Please notify.

Thank you

Ning

Because for the same vendor id, you have a (employee id) id of the person twice in the target table. As Boneist said "fix data, difficulty of the request, fix the requirement...". »

How many sellers are there in your target table?

Update multiple columns from multiple tables in a single UPDATE request

Hello
I'm trying to figure if I'm heading in the right direction.
I want to update multiple columns from multiple tables in a single UPDATE request. Also, I would like to update multiple columns in a table from the tables.
Scenario 1
```
UPDATE Table2, Table 3
SET T2.Column1 = T1.Column1 
,T2.Column2 = T1.Column2
,T3.Column2 = T1.Column2
FROM Table1 T1, Table2 T2, Table3 T3

Scenario 2
```
UPDATE Table3

,T3.Column4 = T2.Column4
FROM Table1 T1, Table2 T2, Table3 T3
WHERE T3.id = T1.id
and T3.id = T2.id
```
Hello

For scenario 1, you must write separate instructions UPDATE table2 and table3.

To guard against someone else change one of these tables while you act so you can copy all relevant data in a global temporary table and update this global temporary table table3.

ENGAGE only when two tables have been changed.

You can write a procedure or an INSTEAD OF trigger to do all this.

For scenario 2, you can reference many tables that you need when new table3. It might be more efficient and simpler to use the MERGER rather than UPDATED. For example:

MERGE INTO table3 dst

WITH THE HELP OF)

SELECT t1.id

t1.column1

t1.column2

t2.column3

t2.column4

FROM table1 t1

JOIN table2 t2 ON t1.id = t2.id

) src

WE (dst.id = src_id

WHEN MATCHED THEN UPDATE

SET dst.column1 = src.column1

dst.column2 = src.column2,

dst.column3 = src.column3,

dst.column4 = src.column4,

update of data from another table
Hi, I would like to help. I Don t know how I can start doing:

I have a table with a column with numbers (primary key) and I need to create another column with the same values,

I want to change a table that has only numeric values (PK) to another
value, so I disable the constraints of linked tables
then I create another column that I called the "d" column and copy the values
from column A to column D

For example.

TABLE XYZ

COLUMN A: COLUMN D: (NEW)

00001 00001
00002-00002
00003-00003
00004 00004

Can I change the values in column A and D of the column will be kept

TABLE XYZ
COLUMN A: COLUMN D:

00001 99901
99902 00002
99903 00003
99904-00004

As the tables that must "point" to the column, I change the values with the new numbering

TABLE ZZZZ

COLUMN B: (the values of the column before the change)

00001
00002
00003
00004
...

I want it like this:

99901
99902
99903
99903
99904
...

In other words, I find the current value in column D of the XYZ table for the new value that is in column a.

I appreciate the help! :)

Here you will find a record in test1 for a record for each line of teste2 in teste2 joined the condition t1.numer_documento2 = t2.numero_documento.

This is called as subquery related Co. What you were doing was under queries that and not to join the top request.
```

       101         1002        null        ABC        800       L

NOW I WANT TO UPDATE T_30 THAT LOOKS AT BELOW:

By top T_30 initially AmendNo pass is null in T_30. Now I want to update
column based on a minimum value of AMENDNO in the column T_20
best way I can explain is:

In the table T_20
For CONTROL 101-> there are two numbers with 1000 but with different Amendno like 1, 2 in.
and
In the T_30 Table for CONTROL 101-> there are two IN. with 1000 but currently null. REQUIREMENT IS NOW
THE TWO DOCUMENTS SHOULD BE UPDATED WITH MIN (AMENDNO) FOR THIS CONTROL T_20. IN THIS CASE FOR THIS CONTROL
101 MIN (AMENDNO) IS '1' (1, 2)

SO 101 RECORDS (BOTH) OF NOW T_30 SHOULD BE UPDATED WITH '1' AS AMENDNO

Once again 101 now have one another IN '1001' with two different 0.1 IN. now T_30 AmendNo should be updated with min (0.1) which is
'0'

production is expected to be lower after update:

SQL> SELECT * FROM T_30;

   CONTROL      PO              AMENDNO  FAC     AMOUNT      USER                            
----------       ----------   ----------      ---        ---------     ----                            
       101       1000         1          MSC        400                      A                               
       101       1000         1          MSC        500          S                               
       101       1001         0          NDP        600           I                               
       101       1001         0          NDP        700           R                               
       101       1002         0          ABC        800           L

Propose any query pls...

Thanks in advance...

I'll try level better to format the pure code in the post...

Concerning
Prasanth

Try this

update t_30 x
   set amendno = (
                   select amendno
                     from (
                            select control, po, factor, min(amendno) amendno
                              from t_20
                          ) y
                    where x.control = y.control
                      and x.po = y.po

access to update only one column in the table?
Hi all

My need is to grant access to update only one column c1 in table t1.
I guess I should use view, could you please give me some examples? Maybe other ideas?
Hello

You can grant privileges on individual columns.
```
GRANT   UPDATE (c1)
ON      t1
TO      grantee_name;
```
Look in the manual of the SQL GRANT language. Annoyingly, in editions recent manual, GRANT is not indexed, but it is in alphabetical order with all other instructions:

Populating one table from another table
Hi Forum...

I'm trying to populate a table from another table using CFQUERY... I have no problem with the selection of data from the original table, but need help to get the data into the new table. I use MX 6.1 and access as the database server.
The two arrays have domain names identical to the same place, and I don't want to have to code all the column names in the selection and insert command. for example

< cfquery name = "GetData" datasource = 'somename' >
SELECT * FROM AssetTable1 WHERE BarCode = "123456".
< / cfquery >

< cfloop query = "GetData" >
< cfquery name = "InsData" datasource = 'somename' >
INSERT INTO AssetTable2 (xxxx...)
VALUES ("#xxxx... #'")
< / cfquery >
< / cfloop >

I hope this makes sense

Thanks in advance

Dave
If your tables are identical structures and their columns are of the same type and position, and both tables are in the same database, then put everything in a single query.

INSERT INTO AssetTable2
SELECT *.
OF AssetTable1
WHERE bar code = "123456".

If the columns were in different positions, then you should be listed explicitly in the INSERT and SELECT the parts, but you get the idea.

INSERT INTO table1 (col1, col2)
SELECT col1, col2
FROM table2
WHERE all that...

Select cursor for update: multiple columns of different tables
Hello

I have two tables test1 and test2. I want to udpate the column (DEPT_DSCR) from the TEST1 and TEST2 using select for update and current tables of the... with the cursor.

I have a code drafted as follows:
DECLARE
v_mydept1 TEST1. TYPE % DEPT_CD;
v_mydept2 TEST2. TYPE % DEPT_CD;
CURSOR C1 IS SELECT TEST1. DEPT_CD, TEST2. DEPT_CD OF TEST1, TEST2 WHERE TEST1. DEPT_CD = TEST2. DEPT_CD AND TEST1. DEPT_CD IS 'AA' FOR THE UPDATE OF TEST1. DEPT_DSCR, TEST2. DEPT_DSCR;
BEGIN
OPEN C1;
LOOP
FETCH C1 INTO v_mydept1, v_mydept2;
WHEN EXIT C1% NOTFOUND;
UPDATE TEST1 SET DEPT_DSCR IS "PLSQL1" WHERE CURRENT OF C1;.
SETTING A DAY TEST2 SET DEPT_DSCR = 'PLSQL2' WHERE CURRENT OF C1.
END LOOP;
COMMIT;
END;

The code above when it is run, declares that it runs successfully. But it does not update the columns you want [DEPT_DSCR].

It works only when we want to update one or more columns of the same table... i. e by providing these columns after ' to UPDATE THE.
I don't know what exactly is the problem when you want to update several columns of different tables.

Can someone help me on this?

Select from another table, when the query returns no result
Hello

I have a question where I'm supposed to retrieve the address of an account id-based billing. However, the table of billing may not have an address. There is a table of addresses that always has an address for an account. If the billing address exists, it should be used, so I can't use the address table. Is it possible in a select statement to query to the billing address and if it does not exist, use the address table.

SELECT * FROM accounts a, b billings WHERE a.accountid = b.accountid

Any help will be greatly appreciated.

Thank you.

I think you need to explain more clearly if

-you only have a couple of "billing" columns which is empty and in this case, you want to use the columns from the table 'accounts '.

- or you have a join with another table that doesn't return data, for example a foreign key "address_id" "billing" is zero and therefore the join to other tables 'address' will return all the data

In the first case, you have already been provided with some examples here, how to use NVL or similar functions to achieve, even if the first post first evaluates the information of 'accounts' and if it is white using information from "billing". According to your description you need the other way around. The second post a subquery recursive useless in my opinion.

In the latter case, you should probably use an "outer" join so that the data in your table "bills" are returned, even if the join to another table is not at all the lines.
```
SELECT
NVL(AD1.ADDRESS_ATTR1, AD2.ADDRESS_ATTR1) as ADDRESS_ATTR1,
NVL(AD1.ADDRESS_ATTR2, AD2.ADDRESS_ATTR2) as ADDRESS_ATTR2,
NVL(AD1.ADDRESS_STREET, AD2.ADDRESS_STREET) as ADDRESS_STREET,
...
FROM accounts a
INNER JOIN billings b
ON a.accountid = b.accountid
LEFT OUTER JOIN address ad1
ON b.address_id = ad1.address_id
INNER JOIN address ad2
ON a.address_id = ad2.address_id;
```
In this way you pick up the address stored in the "invoices" table, if it existed, otherwise you pick up the address assigned to the "accounts" table I used an inner for the second address join join because you said that the account always has an assigned address.

Kind regards
