Is full text search possible in oracle 10g express edition. If so, how is it possible. I browsed many places but couldn't find that.
View 1 Replies View RelatedI am on Oracle 11.2.0.3 on Linux and have implemented Oracle Text.I created Oracle Text indexes with default setting. However in an oracle white paper I read that the default setting may not be right. Here is the excerpt from the white paper by Roger Ford:URL....(Part of this white paper below....)Index Memory.
As mentioned above, cached $I entries are flushed to disk each time the indexing memory is exhausted. The default index memory at installation is a mere 12MB, which is very low. Users can specify up to 50MB at index creation time, but this is still pretty low. This would be done by a CREATE INDEX statement something like: CREATE INDEX myindex ON mytable(mycol) INDEXTYPE IS ctxsys.context PARAMETERS ('index memory 50M'); Allow index memory settings above 50MB, the CTXSYS user must first increase the value of the MAX_INDEX_MEMORY parameter, like this: begin ctx_ adm. set_ parameter('max_index_memory', '500M'); end; The setting for index memory should never be so high as to cause paging, as this will have a serious effect on indexing speed. On smaller dedicated systems, it is sometimes advantageous to temporarily decrease the amount of memory consumed by the Oracle SGA (for example by decreasing DB_CACHE_SIZE and/or SHARED_POOL_SIZE) during the index creation process.
Once the index has been created, the SGA size can be increased again to improve query performance." (End here from the white paper excerpt)My question is:
1) To apply this procedure (ctx_adm.set_parameter) required me to login as CTXSYS user. Is that right? or can it be avoided and be done from the application schema? This user CTXSYS is locked by default and I had to unlock it. Is that ok to do in production?
2) What is the value that I should use for the max_index_memory should it be 500 mb - my SGA is 2 GB in Dev/ QA and 3GB in production. Also in the index creation what is the value I should set for index memory parameter - I had left that at default but how should I change now? Should it be 50MB as shown in example above?
3) The white paper also refer to rebuilding an index at some interval like once in a month: ALTER INDEX DR$index_name$X REBUILD ONLINE; We are on Oracle 11g and the white paper was written in 2003.
I have one table for eg. TB_Fruits.
In that i have one column FruitsName(Varchar)
In that column i am storing string in comma separated values.
Select FruitsName from tb_fruits;
Result: orange,banana,apple
Now the issue is suppose if i try to insert any of these fruits name again then it should not allow me to insert.
Suppose now if i try to insert ('grapes,banana')
or
('apple,grapes')
the orange,banana,apple can be in any position.
How to check if any of these names already exist or not in the column fruitsname?
I cannot use like or INstr function here. because the position is not fixed not even string.
I want to select the view names from text column in dba_views.
View 7 Replies View RelatedHave got basic form on a table and have a textarea which holds Notes added by user.
So Notes database field is updated on Save / Apply changes button being pressed.But would really like any text added / appended to the Notes field to be prefixed by userid and date / timestamp.
Is it possible via dynamic actions or Javascript to have any new text added / typed to be auto prefixed as per above.
Would only want the first key press in the filed to trigger the auto-prefix and if added text was deleted then the auto prefix to be deleted as well ?? If user doesn't press Save / Apply changes obviously want to leave existing Notes as is.
Is there text changed trigger with text item function like when_list_changed trigger of list item?

View 26 Replies View RelatedIm trying to insert a number specified by the format for ex. S999.99, but the original text is of the form S99999, is there any way i can insert the data which will store it in the DB with the datatype as Number(5,2), the decimal is not present in the supplied value(through PreparedStatement) but needs to be put while inserting into the DB.
P.S.- 'S' in S999.99 signifies the sign(+/-).
I have a table of documents (excel, word, pdf, txt) stored in blob column. I want that SCORE returns the number of occurrences within each document, so I'm using this piece of code:
SELECT bdt.*, SCORE(1) AS score_1, DBMS_CRYPTO.HASH(archivo, 3) AS cod_hashFROM crg_ctx_archivos_recibidos bdt
WHERE CONTAINS(archivo,'<query> <textquery lang="SPANISH" grammar="CONTEXT">DEFINESCORE(paz, OCCURRENCE * 0.1)</textquery> <score datatype="INTEGER" algorithm="COUNT"/></query>', 1) > 0
ORDER BY SCORE (1) DESC;
However I'm getting a maximum score of 10, but I know one of these documents have 490 matches. How can i get the exact number of matches per document? I'm using Oracle 11.2
In Application Builder, is there a way to searching the application and replacing text within it?
I have an application item named "FORMAT_TYPE1". I would like to perform a find and replace action (just like a word processor) where any part of the application that has name or text "FORMAT_TYPE1" in whole or in part is replaced by the text "FORMAT_CATEGORY1". For example:
FORMAT_TYPE1 becomes FORMAT_CATEGORY1
&FORMAT_TYPE1. becomes &FORMAT_CATEGORY1.
The find/search would do it in any attribute, source code in the application. There is only a Search Application feature, which is useful in identifying places, but lacks any replace function. Is there something else that will do this, besides exporting, editing the source code in a text editor, and then importing the application again?
I need to export large number of records from select into the text file. It's about 2milion records.I can do it by PLSQL (see below) where executing of process takes time too much. How to export to text file faster?

I have a multi record field of five rows. And 3 values.
the values are
IT
CSE

And i have one text item name is COUNT.
how to show the total number of records in Text item .
it is possible in an Apex interactive report to sort text as number?
For example, a series of text rows:
4
10
2
would sort as:
10
2
4
if it were text. What I would like to see is:
2
4
10
By default number that "starts" with a leading zero with decimals - zero is removed. 0.49 => .49
I'm adding for e.g. the mask "FM990D0999". 0.49 => 0.49
Ok this is fixed.But if I have an integer without decimal. 1 => 1.0
If I change the mask to FM990D9999 1=> 1.
I would like to have a zero leading when it's 0.49 but also no decimal when it's an integer => 1
