Put the query in a CURSOR and use the %ROWTYPE of that cursor.
CURSOR C is select * from something;
C_nt is table of C%rowtype;
NOTE From my experience, those a.* don't always match up to those b.*. I've always had to declare the columns.
SELECT COUNT(*) FROM SYS.ALL_VIEWS;
Is not a simple query. ALL_VIEWS is a very complicated view, it has many joins requiring special logic to determine what the calling user is actually allowed to see.
You can use all_views to see the logic behind all_views, this is how it looks on 19c.
select OWNER, VIEW_NAME, TEXT_LENGTH, TEXT, TEXT_VC,TYPE_TEXT_LENGTH, ...
Simplest solution: the queries are actually not the same.
Not so obvious solution: the sessions from the application server use different optimizer or NLS parameters and this affects the optimizer in a way it choses another execution plan due to different features enabled, different estimated query cost, NLS specific indexes. You can find some of these ...
sum(b.cost) as total_Cost
from Ess.TZeewrld a
left join Ess.Wrldest b on a.account_number, = b.account_number,
group by b.Start_Date, b.End_date;
For starters, assuming we're talking about Oracle (given the reference to TOAD), the group by clause must explicitly include every non-...
I intend to to make password file, spfile and control files as part of my backup script
Let RMAN take care of both the SPFILE and Control Files:
CONFIGURE CONTROLFILE AUTOBACKUP ON
The Password File should be swept up by your Server backup.
I was able to do this by using a Select As statement.
INSERT INTO TARGET_CROSSREF_TABLE
(SELECT 0 AS PRIMARY_KEY,
DATA_SOURCE_TABLE.FOREIGN_KEY_COND AS FOREIGN_KEY_COND,
1 AS FOREIGN_KEY_LITERAL
FROM DATA_SOURCE_TABLE WHERE >CONDITION GOES HERE<)
Note that I have a trigger for the primary key that forces it to be correct. I just needed something in ...
The exact queries for SGA and PGA tuning you might be looking for are:
SELECT sga_size, sga_size_factor, estd_db_time_factor
FROM v$sga_target_advice ORDER BY sga_size ASC;
SELECT round (PGA_TARGET_FOR_ESTIMATE/1024/1024) target_mb,
You should ...
SQL> SELECT 'error detail : ' || &ERROR_DETAIL from dual;
Enter value for error_detail: 'the field x.y is mandatory'
old 1: SELECT 'error detail : ' || &ERROR_DETAIL from dual
new 1: SELECT 'error detail : ' || 'the field x.y is mandatory' from dual
Oracle® Database, Administrator’s Guide, 12c Release 1 (12.1) describes this
Enabling Automatic Memory Management
With MEMORY_TARGET set, the SGA_TARGET setting becomes the minimum size of the SGA and the PGA_AGGREGATE_TARGET setting becomes the minimum size of the instance PGA. By setting both of these to zero as shown, there are no minimums, and the SGA ...
You should not set SGA_MAX_SIZE parameter when using AMM.
It fixes the SGA size.
If you set pga_aggregate_target to non-zero value when using AMM, then you set a lower bound for PGA size. This is usually not required.
Parameter pga_aggregate_limit sets upper PGA bound. For the start, leave it to default value.
