VARCHAR2 (100) Changes Column To VARCHAR2 (100 Byte)
Oct 24, 2007i 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.
Substitute Column Name From Variable For Select Query?
Jan 24, 2012In a select query, I want to substitute the column name from a variable (In turn from an array of column names). Details are given below. I am getting an error as mentioned below.
Create table Test1(IDNumber(10),
Namevarchar2(100),

Sitevarchar2(100));
Insert Into Test1 values(10,'Thomas','Manager','LA');
Insert Into Test1 values(11,'George','Chairman','LA');
declare
MTest1Test1%RowType;
str1VarChar2(1000):='Name';
MValue1Varchar2(100);
begin
Select * Into MTest1 from Test1 where ID=10;
str1:='Select MTest1.'||str1||' from dual';
execute immediate str1 into mvalue1;

SQL & PL/SQL :: Substitute Column Name From Variable For Select Query
Jan 27, 2012In a select query, I want to substitute the column name from a variable (In turn from an array of column names). Details are given below. I am getting an error as mentioned below. sort it out?
Create table Test1(ID Number(10),
Name varchar2(100),
Description varchar2(1000),
Site varchar2(100));
[Code]...
I am getting the error:
ORA-00904: "MTEST1"."NAME": invalid identifier
ORA-06512: at line 9
My objective is to get the name 'Thomas' in the variable - MValue1. I don't want to use the statement MValue1:=MTest1.Name because, moving forward, I want to have the column name to be dynamic, taken from an array of column names.
I need to achieve it by giving only one select query to get entire record and fetch the column values one by one, by substituting the column name from an array of column names, instead of writing that many lines of code / querying that may times to the database.
Client Tools :: How To Substitute Value From A Query In Sqlplus
Apr 2, 2012I need generate a script like this.
spool loadvalues.sql
INSERT INTO SALES(column1, column2, column2) SELECT( COLUMN1, COLUMN2, COLUMN3) FROM TABLE_NAME;
spool off;
I would like to substitute TABLE_NAME with each value from the following query;
select table_name from user_tables
where table_name like 'SALES%'
so there are about 45 SALES tables ex: SALES_IDAHO,SALES_MICHIGAN etc.so my spool file(loadvalues.sql) should look like this ex:
INSERT INTO SALES(column1, column2, column2) SELECT( COLUMN1, COLUMN2, COLUMN3) FROM SALES_IDAHO;
sales_michingan should have script like
INSERT INTO SALES(column1, column2, column2) SELECT( COLUMN1, COLUMN2, COLUMN3) FROM SALES_MICHIGAN;

Reports & Discoverer :: Lexical Parameters Are Used To Substitute Multiple Values At Run Time
Jan 15, 2012 I studied a document about lexical parameter in that it says "Lexical parameters are used to substitute multiple values at run time and are identified by a preceding '&'. Lexical s can consist of as little a one line where clause to an entire select statement"
Select * from emp, deptno &where.
and i know about substitution variables using & is this are same (lexical and substitution) or different.

SQL & PL/SQL :: Using Clob Instead Of Varchar2
Mar 23, 2010in our application we are using clob column instead of varchar2 because varchar2 does not allow more that 4000 chars, so Using clob allows to put data of any length, will it cause performance issues ? we have this column in almost in all tables .

10g - Some VARCHAR2 Fields Empty?
Jul 21, 2011Once a year in the application we have a specific query that gets used a lot. It's an UPDATE that updates a single record in a single table with a few different datatypes, but the issue is happening with one of the VARCHAR2 fields. It updates one VARCHAR2(2000) and three VARCHAR2(4000) fields at the same time.
This year, 9 of the 95 times it was used resulted in one of the VARCHAR2(4000) fields as null in the database. The users would not want this field to be null and 5 of the 9 have told us they entered something (the form they're filling out is a research proposal and leaving this field empty would be pointless because it's part of the funding request, so they're not doing it). The application isn't doing it because it's not consistent. I've checked the application and these fields can't be nulled any other way.
We just found the issue so I looked back over the past years back to 2005. Last year it didn't happen at all. In 2010 it happened a handful of times. Some years there were even more times. It's not always the same field but it's always a VARCHAR2 of at least 2000 characters.
I have a lot more information but it's all just details (let me know if you need to know more). I'm wondering if there is a bug in 10g with these types of fields. I don't believe it's malicious behavior on an individual's part but I suppose that's always possible.
how to research something like this. I tried to get access to Oracle Support and the Knowledge Base I heard they have but it doesn't look like I can do that

Oct 18, 2012I have a question respect to remove spaces from a varchar2.
The varchar2 is '7987451 1234567' and i need that string like '7987451 1234567', because the field has a length of 15.
i try with this, but does nothing

Other possibilities are find several spaces and try to replace with only one, but would a heavy work (may be with sentences Loop).
This problem is now in our loading processes. Exists some function to replace spaces between numbers of varchar2?

Performance Of CHAR Versus VARCHAR2 In VLDB DW
Jul 20, 2010With a very large database (VLDB) for a data warehouse (DW) using primarily a STAR based schema in an environment in which time (both human and CPU) is orders of magnitude more valuable than storage capacity, is there any signficant difference in query performance when tables have all fixed length (CHAR) columns compared to tables with variable length (VARCHAR2) columns?
I realize this is one of those "in general" questions so considering "a given VLDB DW environment" with all other things being equal, what, if any, is the time based performance difference between a database of tables with all fixed sized columns versus one of tables with variable length columns ?
