creating a text index using the section group parameter? The problem that I am having is when I create my text index and perform a query using Score, I do not get the correct results back.
select score(1) from mybaby where contains(name,'Mommy',1)>0;
I 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'm new to Oracle Text. I want to implement search for the unique ids. Like google search when the user start typing 123 it need to brings anything starting with 123 and has show like entries how google will shows. When I add number 4 to like 1234 then it has bring numbers starting with 1234.
View 2 Replies View RelatedI am new to the forum as well as SQL programing and I need to have the following criteria writen in my WHERE so all three of these criterias are included in the same report (perhaps, each will have its own section).
1. PCT_To_Goal < 60
AND (round ( (opened_period / expected_Goal ), 2 ) * 100) >= 100
2. opened_period >= 3 and number_to_date = 0
3. PCT_To_Goal < 30
AND (round ( (opened_period / expected_Goal ), 2 ) * 100 > = 50
AND round ( (opened_period / expected_Goal ), 2 ) * 100 <= 100)
I have column and loading time stamp like below.
RECORDTIMESTAMP TIMESTAMP DEFAULT to_timestamp(to_char(sysdate, 'DD-Mon-YYYY HH24:MI:SS')||'.0', 'DD-Mon-YYYY HH24:MI:SS.FF1') NOT NULL ENABLE
But RECORDTIMESTAMP data looks like '4/8/2009 5:48:00.000000 PM' I would like to supress 3 zeros in milli seconds section.( 3 more zero in milli seconds section)
How a truncate command comes under DDL section, instead DML. All the operations happening inside the object is called DML and ON the object is called DDL.

View 1 Replies View RelatedI have a problem here.Normally, we use &p_where inside a sql script in condition sectione.g :
select name from member where name like 'a%' &p_where order by name;
may i use this kind of parameter in table section?e.g :
select name from &p_table where name like 'a%' and status = 'a' order by name;
the reason i need to do is there are 2 different server. but i need retrieve same info.server ABC have table A but don't have table B and server DEF have table B but don't have table A.
Is there any other method to solve this problem?
I am getting some odd results from a Database Insert Function. The function receives an Array of elements. The elements are a defined structure (containing around 21 data items). I need to insert these records into an Oracle table.For each element of the Array the function reads the structure into a local c structure of the same type.
I then go through this local structure and get a copy of the data into local variables declared in the EXEC SQL BEGIN DECLARE SECTION of the function. I then use the local vars to do the insert, using null INDICATOR variable to handle those variables that could be empty. The local variables look like this....
EXEC SQL BEGIN DECLARE SECTION;
int dbServiceTypeId;
int dbRecordType;
char dbRbmCustRef[MAX_CUST_REF_LEN];
int dbServiceSeq;
[code]...
BUT.. when I uncomment the dbCOS variable (even though I don't populate it or try to include it in the insert) I get the following in the table (The RATE value goes missing completely and the multiplier is wrong)...
ID SERVICE CODE R/T RATE MULTI
41325-SCODE-1084 1 542139762
11326-SCODE-1086 1 542139762
11326-SCODE-1086 2 542139762
21327-SCODE-1087 1 542139762
21327-SCODE-1087 2 542139762
21327-SCODE-1087 3 542139762
21327-SCODE-1087 3 542139762
However, a printf statement just before the insert based that returns the variables shows the following...
Service Type ID: '4'
Record Type ID: '1'
Service Cust Ref: '1325-SCODE-1084'
Service Unit Rate: '1200.00'
Indeed, for this record the Multiplier doesn't even get populated. The other odd thing is if I recomment the dbCOS but remove the dbOraDateFmt variable definitions, it corrupts the data again, though different fields. I can't understand why individual local variables are behaving this way. Is this a problem with the way variables are declared in this section?

View 2 Replies View RelatedI'm trying to group sets of data based on time separations between records and then count how many records are in each group.
In the example below, I want to return the count for each group of data, so Group 1=5, Group 2=5 and Group 3=5
SELECT AREA_ID AS "AREA ID",
LOC_ID AS "LOCATION ID",
TEST_DATE AS "DATE",
TEST_TIME AS "TIME"
FROM MON_TEST_MASTER
WHERE AREA_ID =89
AND LOC_ID ='3015'
AND TEST_DATE ='10/19/1994';
[code]....
Group 1 = 8:00:22 to 8:41:22
Group 2 = 11:35:47 to 11:35:47
Group 3 = 15:13:46 to 15:13:46
Keep in mind the times will always change, and sometime go over the one hour mark, but no group will have more then a one hour separation between records.

View 1 Replies View RelatedI read that rownum is applied after the selection is made and before "order by". So, in order to get the sum of salaries for all employees in all departments with a row number starting from 1, i wrote :
select ROWNUM,department_id,sum(salary) from employees group by department_id
If i remove rownum, it gives the correct output. Why can't rownum be used here ?
Have 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?
