(a.SiteId = c.SiteId))
In the above query, is there any degradation of performance could I continue with the same query
or there is any other solution to speed up the query.
in a select statement these many cases are allowed ah?
Please could someone help me in this?
Thanks in advance
Good bye

Update using a function in the select statement
Hello
Is it possible to do the follwing.
I tabele and a custom function, the custome service will update the column (amount) of the table based on the value of going through the function of the select statement.
SELECT id, stock, where an id = get_update (id);
Now
Get_update function will return the same id I'm passing and update the column amount to a value in the
table a.
When I run the satament selection I have the updated data in the column amount in my first executtion, but if execute the same statement, again, I see the changes reflected. is it possible to get data updates to the first performance himself.
the function is of type PRAGMA AUTONOMOUS_TRANSACTION
ConcerningIndeed a strange requirement and probably not the way to go in a production environment. But anyway is a way to achieve your goal
SQL> create table a as select 12 id, 500 amount from dual union all select 13 id, 600 amount from dual / Table created.

uniol all in the select statement
Hi I have a situation where I have to return the value based on the if statement, is it possible to put union all in the select statement
My use case is
IN the column State
If column01 > 0 to condtion 't'
IF column02 > 0 that the condition of 'Y '.
Condition IF COLUMN03 > 0 THAN 'w '.
If COLUMN04 > 0 that the condition of "Z".
Select 't'
TableName
where column01 > 0
Union of all the
Select "y".
TableName
where column02 > 0
Union of all the
Select 'W '.
TABLENAME
WHERE COLUMN03 > 0
I have what it takes to show value as it
EmpName, condition, empno
Jerry, T, 0158754585
TOM, Y, 0054789568
Am in oracle database 11 g 2
Yes you can put all THE UNION here
Select empname, 't' State, empno from tablename where column01 > 0
Union of all the
Select empname, 't' State, empno from tablename where column02 > 0
Union of all the
Select empname, condition of "W", empno FROM tablename WHERE COLUMN03 > 0
Union of all the
Select empname, condition of "Z", empno FROM tablename WHERE COLUMN04 > 0
and if you are looking for how to remove duplicates because your line might have satisfied all the conditions and my happen 4 times in your result set, you just need to give them an order and filter it.
For example, you want this
If column01 > 0 to condtion 't'
ELSE IF column02 > 0 that the condition of 'Y '.
Another condition of THAN > 0 IF COLUMN03 'w '.
otherwise if COLUMN04 > 0 that the condition of "Z".
Select empname, condition, empno, in
(
Select a.*, row_number() over (partition by empno arrested by myorder) rn
Of
(
Select empname, 't' State, empno, 1 myorder tablename where column01 > 0
Union of all the
Select empname, 't' State, empno, 2 myorder tablename where column02 > 0
Union of all the
Select empname, condition of "W", empno 3 myorder FROM tablename WHERE COLUMN03 > 0
Union of all the

mixture of column type in the select statement
Oracle 11g r2.
tab_test (name varchar2, blob... photo)
(1) select general use *.
Stored procedure: open ref_cursor to some * of table_test...

It works very well.
(2) enter the name of the column in the select such as

ERROR: java.sql.SQLSyntaxErrorException: ORA-00932: inconsistent data types: expected - got BLOB
My question, if I specify the column names in the select statement, including the varchar2 and blob, how can I registerOutParameter (1, OracleTypes.CURSOR);?
Thank you

PS The number of returned columns, in real case schenario, is a little, so I prefer to specify column names.

function() nested in the select statement
Oracle 11g. Try to nest a function within the select statement. Goal: get the average customer rating for each of the qualified user.
Select user_name, f_get_avg_cust_rating() "Notation.
of u, OTHER_TABLES o TAB_USER
where u.id = o.id and another condition matched;
How Oracle would deal with the sql. Is it
(1) first of all display records based on the where clause, then call the f_get_avg_cust_rating() for each of the selected records OR
(2) for the analysis in tables, the f_get_avg_cust_rating() will be called for each record met?

I tried to use a statement select count nested inside the original SELECT statement but without success.
JeffYou should be able to use a CASE statement for this in collaboration with the County. COUNTY does not indicate that null instances no I have not specified a part to the CASE ELSE (so the default value is NULL).
COUNT(CASE ST.GENDER WHEN 'F' THEN 1 END) as Female_count, COUNT(CASE ST.GENDER WHEN 'M' THEN 1 END) as Male_count,
