SQL & PL/SQL :: Write A Function That Receive As Parameter A Datatype Varchar2?
Jul 18, 2012
here is the situation, I have to write a function that receive as parameter a datatype varchar2 and validate if the letter is less than "A" or greater than "Z", it must print do not correct, or correct depending on the situation, no problem so far, the only problem I've got is: If the symbol is ";" is valid, but i do not know how to write it, It does not depend on the PL/SQl languaje but depends on the logic itself.
DECLARE
v_nombre varchar2(20):='john;%';
vv varchar2(1);
begin
for i in 1..length(v_nombre) loop
[code]...

I'm facing a problem where I create a form and I want to feed time in "HH:MI" format, Firstly I choose the "Date" datatype, but during the feeding of time i.e "00:30", means if I want to feed only mints, then it doesn't accept, at the other hand if I feed "01:30" means mints with hr then it accepts.
To get rid of this problem I changed datatype "Date" to "Varchar2".
I create 3 columns on my form "TTL_WORKING_TIME" - "TTL_RUN_TIME" = "BRK_DWN_TIME". If I get any value in "BRK_DWN_TIME" column thn it has to be distribute in 3 or 4 reason of B/D, means if I get 00:30 mints brkdwn thn 00:15 mints for "reason1" and 00:15 mints for "reason2".
How I make calculation where I use "Varchar2" datatype.

I have to change the datatype of a column from CLOB to varchar2, without changing the order of the columns. The table has no data.
I could find any other way other than dropping the CLOB columns and then adding new columns with varchar2 datatype. But this changes the order of the columns in the table.

I am facing issue related to Number data while it is being converted to Varchar2, it is automatically getting rounded off after 32 decimal place.My database version is "Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production".
1) create table test18 ( col1 varchar2(10), val Number);
create table succeeded.
2) insert into test18 values ('First', -347026.6408499652467480885711448714129679); -- After decimal 34 digits
1 rows inserted
insert into test18 values ('Second', -347026.64084996524674808857114487141296); -- After decimal 32 digits
1 rows inserted
3) select * from test18;
COL1 VAL
---------- ----------------------
First -347026.6408499652467480885711448714129679
Second -347026.64084996524674808857114487141296
4) As per the requirement, all the columns would need to be concatenated as a single string along with comma delimiter
select col1 || ',' || val as record_string
from test18;
RECORD_STRING
---------------------------------------------------
First,-347026.64084996524674808857114487141297
Second,-347026.64084996524674808857114487141296
"First" string got rounded off to 97 (last 2 digits) instead of 9679 but for "Second" record it holds the actual value.Only thing which I could figure out while the number is getting type casted to String, it is getting rounded off to 32 decimal place.throw off some light on it and provide the solution how the original record can be kept intact without rounding off.
Expected Output_
RECORD_STRING
---------------------------------------------------
First,-347026.6408499652467480885711448714129679
Second,-347026.64084996524674808857114487141296

As per my knowledge, RANGE is better suited for DATE or NUMBER. and INTERVAL partition is possible on DATE or NUMBEr . Column PROFILEIts is of VARCHAR2 datatype. I know still I can partition as Oracle internally convert varchar2 to number while inserting data. But INTERVAL is not possible. How to RANGE partition on PROFILE ? Column CREATED_ON :It is of NUMBER with decimal

I'm working on trying to write a shell script to parse a parameter file, but at the same time I want to be able to overwrite the parameter file settings with other command line settings. For instance if my par file had export/import settings for the username, password, schema, etc;
I wanted to run the same export/import with those settings for a different schema. I want to be able to put the schema=<different_than_par_file> after the parfile=<parfile.par and have the parfile be read and applied for everything except the different schema.
Right now I'm storing the cmd line and parsing it again looking for other parameters besides the parfile.

Create a function which will indicate if a given record in a table is unique or not. Unique means the data is occurring only once in the entire table.
Function should be in this signature
function IS_UNIQUE (tableName in varchar2,tableAttribute in varchar2)
return number
.....
begin
//logic to check if given data is unique
return 0; //return 0 if data is unique
else
return 1; //return 1 if data is duplicate
end;
Once I run this query
select attribute1 from table1 where IS_UNIQUE(table1,attribute1)=0
All records of attribute1 which are unique need to be fetched. Similarly, select attribute1 from table1 where IS_UNIQUE(table1,attribute1)=1 should return all records of attribute1 which are duplicates.

i am fairly new in the oracle arena, but what would cause a statement such as
ALTER TABLE TEST_TABLE MODIFY text_field1 varchar2(100) DEFAULT 'testval' NULL
to change a column's type from VARCHAR2(100) to VARCHAR2(100 byte)? i found a few mentions of the 100 byte concept online but nothing that jumped out at me.

I'm trying to execute a dynamic sql that calls a function. But that function has inserts and deletes inside and this way it can't be called through a select statement. And to be worst, it has an other problem, my function uses a record type as parameter.
My code (sample):
-----------------
DECLARE
type r_parameters is record
(cd_query cons_query_param.cd_query%type,
cd_usuario cons_query_user.cd_usuario%type,
nr_param cons_query_param.nr_param%type,
vl_param varchar2(2000),
[code].....
