SQL & PL/SQL :: Add Variable Number Of New Columns To Existing Table Temp

Feb 24, 2010

I want to add a variable number of new columns to an existing table temp (with column provided).

Example:

NewColumnNo = 4
-> the columns shall be named rate_1, rate_2, rate_3 and rate_4
-> the values shall be = Column / NewColumnNo

The result shall be like this:

create table temp_res (prodid integer, rate_1 number, rate_2 number, rate_3 number, rate_4 number);
insert into temp_res values(1, 0.25, 0.5, 0.75, 1);
insert into temp_res values(2, 0.25, 0.5, 0.75, 1);
insert into temp_res values(3, 0.25, 0.5, 0.75, 1);
insert into temp_res values(4, 0.25, 0.5, 0.75, 1);
insert into temp_res values(5, 0.25, 0.5, 0.75, 1);

SQL & PL/SQL :: Create Temp Table From A File

Aug 22, 2011

I'm having some trouble dealing with the PL/SQL coding. At the moment, I have a file (set of data) that is read using java. An array is created (line by line) and is passed into a temp. table, which is then called by the plsql (call PKG_xxx.PRC_xxx...) script/command for processing. Is there any way I could directly get the file loaded into plsql (into a temp. table maybe?)

The data are just numbers and letters. I already got the PL/SQL part to select the set I want for different cases. All I need is to get the file (directly or indirectly) for the procedure without going through java.

Oct 31, 2013

I have 2 tables that doesn't have primary keys. These 2 tables have same number of rows. I want to create a new table from getting some columns from table1 and some columns from table 2. I want to combine first row from table1 and first row from table2.

Below is example

TABLE1

ACOL1 ACOL2 ACOL3
A1 A2 A3
B1 B2 B3
C1 C2 C3

TABLE2

BCOL1 BCOL2 BCOL3
11 12 13
21 22 23
31 32 33

COMBINED_TABLE

ACOL1 BCOL2 BCOL3
A1 12 13
B1 22 23
C1 32 33

I tried below query but no luck. It gives below error:

Query : create table COMBINED_TABLE AS select a.ACOL1, b.BCOL2, b.BCOL3 from (select ACOL1,rownum from TABLE1) a, (select BCOL2, BCOL3, rownum from TABLE2) b WHERE a.rownum = b.rownum

Error : ORA-01747:"invalid user.table.column, table.column, or column specification"

PL/SQL :: Temp Tablespace Space Due To GTT Table

Sep 3, 2012

We are using a GTT table to store the summarize data and display it on same screen(10g 10.2.0.5). Now we are facing temporary tablespace space issue very frequently as our client do not enable the auto extend on for temp table space. We have analyzed the AWR and came to know that there are 900000 inserts per hour on an average. Client DBA Claims that there are sessions(1or 2) which inserts the data in temporary table continuously for 2-3 days.

According to him one session is running from 28th Aug and problem comes on 2nd Sep and after killing the problematic session the application will work fine. Generally this problems come on weekend. I have discussed with our dev team and as per them there is no session leakage issue.

following is the insert statement:
INSERT INTO DT_CA_STNDALN_DETAILS_TMP (ORG_ID,BA_PRODTYPE_ID,MAX
TENOR,GROSSLIMIT,GROSS_UTILISATION,HAS_MDR,HAS_CLUSTER,SIGN_IN
D,GROSS_AVAILABILITY,COLLATERAL,NET_UTILISATION,DT_CA_STNDALN_DE
TAILS_TMP_VER,DM_LSTUPDDT,NET_AVAILABILITY) VALUES (:1,:2,:3,:4,
:5,:6,:7,:8,:9,:10,:11,:12,sysdate,:13) ;

Cursor Versus Global Temp Table

Jan 16, 2013

We had an issue with a PL/SQL package taking hours to run as a concurrent program. Database version is 10.2.0.4.0, running on Linux x86 64-bit. A tkprof'd trace file revealed the problem SQL statement to be a cursor. This one SQL statement would run for 3+ hours. I copied the SQL statement and ran it in TOAD and it completed in seconds, returning the exact same result set. To resolve the issue in the PL/SQL package I created a global temp table and ran the exact same SQL statement as an INSERT into the global temp table.

Again, instead of hours, the SQL statement completes in seconds. If I revert the change, it goes back to taking hours. I've attached the relevant sections of the tkprof showing the two SQL statements (identical other than the insert in front of one) and the resulting explain plans and performance data. I've always been under the impression that a cursor was a better option than a temp table and I've never run into a situation where the same SQL statement runs so much longer when executed as a cursor.

SQL & PL/SQL :: Performance With Union And Global Temp Table

May 24, 2010

I have a view, which has a union. (Union is required because of the nature of the data fetched). THis view is later joined with a global temp table which holds the -say employee Id the user selects.

So at runtime there is a join with the global temp table and the view. But the performance is really bad. I have tried using various hints, like materialize, /*+ CARDINALITY(gtmp 1) */ etc.

When i query the view alone,. the performance is good. When I remove the union, the performance is good. Some how with the union- there is a full table scan on one of the joining tables.
