select a.mid
FROM table_a a

ON a.dept = b.dept
JOIN table_c c
ON b.eid = c.eid

AND (a.i1 or a.i2 or a.i3 or a.n1 or a.n2 or a.n3 or a.t1 or a.t2 or a.t3 ) IS NULL
In the below code, do I need the 'NOT NULL' after the 'state char(2)'? I am guessing that I do not need it since I have the CHECK constraint on the column.
CREATE TABLE employee(
id PRIMARY KEY,
first varchar(20) NOT NULL,
middle varchar(20),
[code]....
I want to put one check box to check all the check boxes.how can i do this?

Whenever i write into this textfile, after the first row entered, for example, the first row string is 'H2001', then it will automatically spacing 7995 spaces. What I want is, when i enter the second row, it will auto write into the file in next row without all the spaces in row 1. I had been tried using trim, rpad, substr. and still don't get the thing that i want.

We are getting the below error on a piece of code that chas been functioning fine for over 4 years..
ORA-06502: PL/SQL: numeric or value error: NULL index table key value
ORA-06512: at "pd.pf33", line 148
The line it's pointing at is merely a FOR loop that opens a cursor (select query) and loops through the items.
FOR rec IN csr_cash
LOOP
END LOOP
This piece of code has been functioning fine for years.. and never got this kind of error on a for loop. Could it be something internal to Oracle/underlying memory issues?
My control file is :

I have a script like this:
------------------------------------------------------------
DROP TABLE CON_TEST CASCADE CONSTRAINTS ;
CREATE TABLE CON_TEST (
IDI NUMBER(10,0),
USERID VARCHAR2(10),
PWD VARCHAR2(10),
NOTE VARCHAR(100)
)
----------------------
But i think if table CON_TEST doen't exist, an error message will appear. I know that in SQL Server we can check if table exists or not. So, i wonder if we can do that in Oracle?
By the way, is there any way to run a file script that contents TABLES, STORED, ... on a developed PC connect to oracle db server? (in case, i'm developing on PC, using Net Service Name to conect to Oracle DB Server)
I'm working on a feature that needs to check every table for data. At the moment I am roundtripping every time and running the query like this:
SELECT 1 FROM dual WHERE EXISTS(SELECT 'x' FROM table_name)
Is there a better way that allows me to get the result for all tables in one trip? I've tried a correlated subquery like this:
SELECT table_name, (SELECT 1 FROM dual WHERE EXISTS(SELECT 'x' FROM table_name) FROM all_tables
but I think that doesn't work because Oracle looks for a table called table_name rather than the value from the outer query.

I am running a GROUP BY query on a few columns of enumerated data like:
select count(*), Condition, Size
group by Condition, Size;
COUNT(*) CONDITION SIZE
-------- ---------- --------
3 MINT L
2 FAIR L
4 FAIR M
1 MINT S
Well, let's say I also have a timestamp field in the database. I cannot run a group by with that involved because the time is recorded to the milisec and is unique for every record. Instead, I want to include this in my group by function based on whether or not it is NULL.
For example:
COUNT(*) CONDITION SIZE SOLDDATE
-------- ---------- -------- ----------
3 MINT L ISNULL
2 FAIR L NOTNULL
2 FAIR M NOTNULL
2 FAIR M ISNULL
1 MINT S ISNULL

View 3 Replies View Relatedcan a table level check constraints have conditional checking (if else clause or case conditional structures) and checks which are limited through something like a where clause which inside the table level check constraints.And can a table level check constraints refer to a column in another table column which should have a the same value.
View 1 Replies View RelatedI am abolute new in PL SQL and I am working on following topic:
I have to check if an entry exists in a table.
- if it exists ...... do something
- if not ...... simply go on
I tried the following:
select Count(*)from products p
where p.productNbr = temp_Nbr
Group By t.produkt;
I fetched the result into a variable entries
if entries > 0 .....
MY problem is the following:
If there are entries (entries>0) --> it works
If there are no entries, entries is not 0 but 'no data found' --> crash
I cannot work with Exceptions because this all happens in a Loop which must go on in both cases!
Usually we check 1 row of data in table and compare if they exist, i want to compare different set of row all together to comapre and take the decisions
eg.
emp table_source
d_key emp_no invol
1 103499 1
1 99262 2
2 103499 1
3 103499 1
3 99262 2
target table
emp_no invol
103499 1
99262 2
103499 1
in the above example i have to check for d_key for set of row exist in target or not, so by above example d_key 1 and 3 has save value in 2 different rows so i want to check if the combination of rows
103499 1
99262 2
as a set appear in source then do nothing else insert so first time d_key 1 both records will insert but for d_key has same set in 2 rows will not be inseted. the number of row can be more than 2 also . so for the given key if we have 3 rows in source then i have to compare all the 3 same set of row in target exist of . in the target i don't have any extra column.
