InterMedia Text Query in Dynamic SQL

I have a query using score and contains interMedia operators that runs without problem from the SQL*Plus command line, but generates a "ORA-01858: a non-numeric character was found where a numeric was expected" error when run via dynamic sql.
The query runs something like this:
select
score(1),
score(2),
a.field1,
b.field2
from
a,
b,
where
b.id (+)= a.id and
b.name (+)= 'test' and
((contains(a.content, 'query', 1) +
(contains(b.valud, 'query', 2)) > 0
I'm trying to avoid an OR clause by adding the two contains clauses together. Could this error be caused by the outer join on table b? If so, why does it run without problems from SQLPlus?

Thanks for the help.
Can you give me an example of how I have to specify the url in the database? For my intranet websites, I was able to use the foln. two formats http://host1/asptest/index.html (and)
URL:http://scott:tiger@host1:80/asptest/index.html
where host1 is the name of the host and 80, the port number.
I need to be able to access the oracle website(http://www.oracle.com/index.html) and run the foln. query,
SELECT id, url FROM test WHERE CONTAINS(url, 'Education')>0;
I tried setting the HTTP_PROXY attribute of the URL_DATASTORE, and specified the url as http://www.oracle.com/index.html in the database, but that didn't seem to help.
Thanks.

Query with Dynamic SQL

Hello,
I would like to create a Dynamic SQL in which change is the name of the table according to the outcome of the first SQL. This is possible?
'WITH TABLE_X AS(SELECT LEVEL LVL FROM DUAL CONNECT BY LEVEL <= 12)' ||
'SELECT A.COL1, A.COL2, B.COL1, B.COL7'                              ||
' FROM TABLE_A' || TABLE_X.LVL || ' A'                              ||
'     , TABLE_B' || TABLE_X.LVL || ' B'                              ||
' WHERE A.COL1 = B.COL1 AND ...    'tables in database

Hi,
Sorry, I don't see what you're trying to do.
"Dynamic SQL" is really a mis-nomer. The number of tables and columns in a query, and their names, must be spelled out when the statement is compiled. There is nothing dynamic about it.
In dynamic SQL, a PL/SQL procedure or another query writes all or part of query just milliseconds before it is compiled, typically using data taken from tables or supplied by a user right then.
For example, consider this static query:
SELECT     a.col1, a.col2, b.col1, b.col7
FROM     table_1     a
,     table_2 b
WHERE     a.col1 = b.col1;Now, say the 1 in "table_1" and the 2 in "table_2" are variables, x and y, that you will want to look up from another table every time you run this query. You can make it dynamic like this:
sql_txt := 'SELECT a.col1, a.col2, b.col1, b.col7 '
     || 'FROM    table_' || TO_CHAR (x) || ' a '
     || ',       table_' || TO_CHAR (y) || ' b '
     || 'WHERE   a.col_1 = b.col1';Now let's make it really interesting. Say that instead of 2 tables, and 1 join condition, you''ll have n tables and n-1 join conditions, where n has to be computed at (actually a split second before) run-time. That is, if n=4, you might need to construct a static query with 4 tables and 3 join conditions, like this:
SELECT     a.col1, a.col2, b.col1, b.col7
FROM     table_1     a
,     table_2 b
,     table_12 c
,     table_2 d
WHERE     a.col1 = b.col1
AND     a.col1 = c.col1
AND     a.col1 = d.col1;You can do that using dynamic SQL, too.
Post an example of the static query you need to build, and describe what parts of it are dynamic, and how you get the values for those parts, and someone will help you write the dynamic SQL.

Rewrite the static query to dynamic SQL

Can any one please help me to write a dynamic query within a pl/sql for the following SQL??
This is for the set ('25','04'). the number of list could be n .
The column_type ranges from(1..6) and
the column_amt1 ranges from(1..6)

This is the part of a procedure.NowThe query is only for type '25' and '04' .It could be more in numbers in future.So I want to maintain a dynamic sql irrespective of the number of types I use.Then first thing you must do is rename column case since it is PL/SQL reserved word (I renamed it to case_id).

Difference between Static SQL Query and Dynamic SQL Query.

Hi,
Please explain the basic difference between static and dynamic sql queries. Please explain with example.

Static: http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10472/static.htm
Dynamic: http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10472/dynamic.htm

Spool SQl data into text file using dynamic sql

Hi,
I am spooling output data into text file using command
select 'select t.mxname,bo.lxtype,t.mxrev'||chr(10)||'from mx_1234567'||chr(10)||
'where <condition>';
here mxname varchar(128),lxtype(128),mxrev(128) all are of varchar type.I want the output in format
e.g Part|1211121313|A
but due to column width the output,I am getting is with spaces.
"Part then blank spaces |1211121313 then blank spaces |A"
how can I remove these spaces between columns.I used set space 0 but not working.
Thanks in advance.
Your help will be appreciated.

Hi Frank,
I have seen your reply for SET LINE SIZE function. But, I could not be able to understand it.
I am facing similar kind of issue in my present project.
I am trying spool more than 50 columns from a table into flat file. Because of more column lengths in few columns, i am getting space. There are so many columns with the same issue. I want to remove that space.so that, data can fit perfectly in one line in .txt file without any wrap text.

Linked server query using Dynamic SQL

I have a Linked server query that takes forever to run. WHen I hardcode the acct# it runs fast. However I want these acct numbers int he where clause to be generated dynamically. For eg: below is what I need:
--Get the 11 Loans from this Table A From the FIRST QUERY
--- Plug those loans numbers in the second query In the WHERE Clause eg should looks like where ACCT in (1,2,3,5)
DECLARE
@sSQL varChar(MAX)
SET @sSQL
=
' SELECT
[Loan] FROM TableA D
EXECUTE(@sSQL)
--2ND QUERY
DECLARE
@sSQL1 varChar(MAX)
SET @sSQL1
='
SELECT Field1,
Field2,
Field3,
Field4,
Field5
FROM LinkedServer.Dbaname.dbo.TableB a
where ACCT in ''('''
+(@sSQL)
+
''')'''--- This needs to look like where ACCT in (1,2,3,5)
select
@sSQL1

Ok, so use this.. instead of your first statement.
DECLARE @sSQL NvarChar(MAX), @output NVARCHAR(100), @ParmDefinition nvarchar(500);
SET @ParmDefinition = N'@sqlout NVARCHAR(100) OUTPUT'
SET @sSQL = N'SELECT DISTINCT @sqlout = STUFF((SELECT '',''+CAST(S2.loan AS VARCHAR(100))
FROM tableA S2
FOR XML PATH('''')), 1, 1, '''')
FROM tableA S1'
EXECUTE sp_executesql @sSQL, @parmdefinition, @sqlout = @output OUTPUT
and use @output instead of @sSQL in the second statement.
You can read about STUFF command @

INTERMEDIA TEXT INDEX를 사용하는 QUERY의 TUNING

제품 : ORACLE SERVER
작성날짜 : 2002-04-12
INTERMEDIA TEXT INDEX를 사용하는 QUERY의 TUNING
===============================================
Purpose
Intermedia text를 사용하는 query의 속도를 향상시킬 수 있는 방안을
알아보자.
Explanation
1. Make analyze all the table in the query
text index를 이용하는 Query 안의 모든 Table을 analyze 해 주십시요.
예를 들어 다음의 command를 이용할 수 있습니다.
ANALYZE TABLE <table_name> COMPUTE STATISTICS;
or
ANALYZE TABLE <table_name> ESTIMATE STATISTICS 1000 ROWS;
or
ANALYZE TABLE <table_name> ESTIMATE STATISTICS 50 PERCENT;
2. Using FIRST_ROWS hint
더 좋은 response time 을 위해서 first_rows hint 를 사용해 보십시요.
database에 기본적으로 설정된 optimizer mode는 choose mode입니다.
이것은 전체 처리시간(throughput)을 가장 빠르게 하기 위한(all_rows mode)
plan을 따르기 때문에 user의 입장에서는 first_rows 보다는 늦다고 느낄 수
있습니다.
Query에 다음과 같이 hint를 주고 performance를 확인해 보십시요.
select /*+ FIRST_ROWS */ pk, col from ctx_tab
where contains(txt_col, 'test', 1) > 0;
단, first_rows hint를 이용하는 경우 자동으로 score 순서대로
ordering 되지 않습니다. 왜냐하면 단어에 부합하는 문서를 찾는대로
즉시 결과로 나타내 주기 때문입니다.
3. Make sure text index is not fragmented
insert, delete 가 많이 되는 table의 경우 index fragment를 제거해 주어야
합니다. Index fragmentation 은 다음과 같이 확인할 수 있습니다.
select count(*) from dr$<indexname>$i; -> A
select count(*) from (select distinct(token_text) from dr$<indexname>$i); -> B
위의 결과가 A/B 의 값이 3:1 보다 크면 optimize_index 를 실행해 주시는
것이 좋습니다. 다음과 같은 command로 index optimization을 할 수 있습니다.
alter index <index_name> rebuild online
parameters('optimize full unlimited');
index rebuild중에 online option을 주면 rebuild하는 중에도 계속 index를
사용할 수 있게 됩니다. 하지만, 가능하면 사용자가 없을 때 rebuild하는 것이
좋습니다.
4. Check execution plan and sql trace.
기본적인 여러 가지 작업들에도 속도가 별로 향상되지 않는다면, 직접
sql trace를 떠서 Execution plan등을 확인해 보는 것이 필요합니다.
예를 들어 SQL*PLUS에서 다음과 같이 sql trace를 뜹니다.
alter session set timed_statistics=true;
alter session set sql_trace=true;
select ..... -> execute the query
실행 후,
exit
user_dump_dest 에 지정된 directory에 trace 가 떨어지면 다음과 같은
command로 tkprof 를 떠서 내용을 확인합니다.
$ tkprof <tracefilename> <outputfilename> explain=username/password

NVARCHAR (MAX) TO PRINT DYNAMIC SQL QUERY TO A SQL FILE

Hi
I have a requirement where i need to write an SP which would construct a huge query using dynamic SQL and save the Dynamic query to a file.
The Dynamic SQL Variable I am using as @NVARCHAR(MAX) but since the query being built is large (>4000 characters), I am not able to select it into a table. PRINT @SQL prints the whole query but SELECT @SQL prints only upto 4000 characterrs.
And I need to save this huge dynamix sql to a file using the SP.
Any thoughts as to how i can achieve this?
Rajiv

This is a know problem with dynamic SQL nvarchar(max) concatenation.
See below for correct assembly of large SQL strings:
CREATE table #temp(qry nvarchar(max));
declare @cmd nvarchar(max);
SELECT @cmd=CONCAT(CONVERT(nvarchar(max),N'SELECT '),
CONVERT(nvarchar(max),REPLICATE (N'A',4000)),
CONVERT(nvarchar(max),REPLICATE (N'A',4000)),
CONVERT(nvarchar(max),REPLICATE (N'A',4000)),
CONVERT(nvarchar(max),REPLICATE (N'A',4000)),
CONVERT(nvarchar(max),N'FROM SYS.TABLES'));
insert into #temp SELECT @cmd;
select * from #temp;
select len(qry), datalength(qry) from #temp;
-- 16022 32044
drop table #temp;

How to rename C00n generic column names in a Dynamic SQL report

I have a an interface whereby the user can select 1 to 60 (upper limit) columns out of 90 possible columns (using a shuttle) from one table before running a report.
To construct the SQL that will eventually execute, I'm using a "PLSQL function body returning SQL query" with dynamic SQL. The only problem is that I have to use "Generic Column Names" option to be able to compile the code and end up with c001 to c060 as the column names.
How can I use the names of the selected columns as the report headings rather than c001, C002... etc?
I do not know beforehand which columns, or how many columns or the order of the selected columns.
I know Denes K has a demo called Pick Columns but I can't access his code. I have a hunch though that he may be just using conditions to hide/show the apropriate columns.
thanks in advance
PaulP

Hi Paul
I would change the Heading Type in the Report Details screen to PLSQL and use the shuttle item to return the column values. e.g.
RETURN :p1_shuttle;
I'm assuming the shuttle already has a colon separated list of the column headings in the correct order?
I hope that helps

Dynamic SQL in table vauled function or CLR

So I have a query that gives me some analysis on the values in a column, in a table. It reurns a small data set.
It gives me the max, min, stdev, avg and some other stats grouped by another column.
I wanted to create a table valued function from the query, so I could do the same analysis on any numeric column, in any table. I would just pass in the column name and the table name as paramters to my table-valued function and it would return the
data set. Then I could join to it and use in other queries.
I thought I would build my query using dynamic SQL and execute it within the function, but I got an error and learn that you can not use execute in a function.
I have never created a CLR function, would this be possible to do it this way? This would be a decent sized step for me, but am willing to learn if possible. Or does anyone know how to solve this problem?
Problem: Pass column name and table name into function and have it reurn a dataset. Use the dataset as a table in other queries, scripts or procedures like a table valued function.
Thanks,
Mike

Dynamic SQL - Inner Join

I just starting to Learn and use Dynamic SQL.
I am trying use a inner join query in dynamic SQL
for Example say 'Select A.id as Itemid , A.name as Itemname from TableA A inner join TableB B On A.ID = B.ID where B.ID typeid = 1 '
for some reason this is not working . i for sure know the query works as when i run the query it works fine. when i try to run it dynamically it give me blank values.
Please let me know if you need more information.
Appreicate Your help!!
Thanks,
Chaitanya

Here is an example for dynamic SQL from BOL:
DECLARE @IntVariable int;
DECLARE @SQLString nvarchar(500);
DECLARE @ParmDefinition nvarchar(500);
/* Build the SQL string one time.*/
SET @SQLString =
N'SELECT BusinessEntityID, NationalIDNumber, JobTitle, LoginID

Basically any query can be run as dynamic SQL. However, static SQL is the first choice. Use dynamic SQL if needed.

Dynamic SQL within a SQL Query ?

is there any possibility to do like this ?
SELECT table_name, XXXXXXXX('SELECT Count(*) FROM '||table_name) tot_rows
FROM dba_tables
WHERE owner = 'SCOTT';or any other trick to run dynamic SQL within the SQL Query?
Hoping....that it should be.
Regards,
Orapdev

One small disadvantage: it is executing 202 SQL statements: 3 "user SQL statements" (the one above and the 2 "select count(*)..."), and 199 internal ones ...How did you get to those numbers?
I just traced this statement and found completely different results:

Build stored procedure from a dynamic SQL query

I have the following method, that receives a string from a textbox and creates a dynamic select command. Since I am using a dataSet I cannot execute a dynamic SQL query by calling a method of a strongly-typed dataset (.xsd). I have been told that the best
way to do this is to pass an array of values to the stored procedure.
But I have no clue how to build the stored procedure.
string[] allWords = txtSearch.Text.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);
string sql = "SELECT Books.ISBN, Books.Title, Books.Tag, Books.Image, Books.photoType, Publishers.Name AS publisherName FROM Books INNER JOIN Publishers ON Books.codPublisher = Publishers.codPublisher WHERE ";
using (SqlCommand command = new SqlCommand())
for (int i = 0; i < allWords.Length; ++i)
if (i > 0)
sql += "OR ";
string paramName = "@param" + i.ToString();
sql += string.Format("(Books.Title LIKE {0}) ", paramName);
command.Parameters.AddWithValue(paramName, allWords[i] + "%");
command.CommandText = sql;
//execute the SQL query against the db...

After hours around this, I have came with this solution.
private SqlConnection sqlConn = new SqlConnection();
private System.Data.DataSet dataSet = new System.Data.DataSet();
private System.Data.DataTable dataTable;
private System.Data.DataRow dataRow;
private SqlCommand search(string searchParam, int searchOption)
SqlCommand command = new SqlCommand();
string sql;
string[] allWords = searchParam.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);
if (searchOption == 1)

Dynamic SQL Query count

Hi,
I need to retieve the number of records that will be retrieved by a query as follows.
How can this be done?
Is there a method to do it using native dynamic sql (open .. for .. using ) instead of DBMS_SQL (Because Native is faster than dbms_SQL )?
The following block demostrates what I need to do where v_query will hold the query text.
declare
v_query varchar2(32000);
v_count number;
begin
select query_text into v_query from groups_table where id =1;
dbms_output.put_line('count = '||v_count);
end;
Thanks in Advance

Is there a way to use sql%rowcount to do something similar?
Afraid not
I mean if there is a way to get better performance in case of very large query. Like for example in oracle forms, when using Query --> count records it retrieves the nubmer of records that will be fetched.
I think you'll find forms simply does a select count(*) from the base table (adding and predicates where necessary).
What are you going to use it for? Maybe there is an alternative route you can take...

Need generic dynamic sql query to generate nodes depending on dealer levels

Input table:
create table #test(dealerid integer ,dealerlvl integer)
insert into #test values(1,1)
insert into #test values(1,2)
insert into #test values(1,3)
insert into #test values(1,4)
insert into #test values(2,1)
insert into #test values(2,2)
insert into #test values(2,3)
insert into #test values(2,4)
insert into #test values(2,5)
insert into #test values(2,6)
go
create table #test2(dealerid integer,node integer,prntnode integer,dealerlvl integer)
insert into #test2 values (1,234,124,2)
insert into #test2 values (1,123,234,1)
insert into #test2 values (1,238,123,2)
insert into #test2 values (1,235,238,3)
insert into #test2 values (1,253,235,4)
insert into #test2 values (2,21674,124,3)
insert into #test2 values (2,1233,21674,1)
insert into #test2 values (2,2144,1233,2)
insert into #test2 values (2,2354,2144,3)
insert into #test2 values (2,24353,2354,4)
insert into #test2 values (2,245213,24353,5)
insert into #test2 values (2,2213,245213,6)
Expected result :
I have two test case here with dealerID1 and dealerID 2
Result for DealerID1
Result needed for DealerID2:
the levels for dealers might change (Dealer1 has 4 levels, and Dealer 2 has 6 levels) so i need to create an dynamic sql query which lists each node as separate columns depending on the levels.
I have hacked the query to give the result I need
select a.dealerid,a.node as Lvl1,b.node as lvl2,c.node as lvl3,d.node as lvl4
from #test2 a
join #test2 b on a.node=b.prntnode
join #test2 c on b.node=c.prntnode
join #test2 d on c.node=d.prntnode
where a.dealerid=1 and a.dealerlvl=2
select a.dealerid,a.node asLvl1,
b.node as lvl2,c.node as lvl3,d.node as lvl4,e.node as lvl5,f.node as lvl6--,a.dealerlvl,a.dealerid
from #test2 a
join #test2 b on a.node=b.prntnode
join #test2 c on b.node=c.prntnode
join #test2 d on c.node=d.prntnode
join #test2 e on d.node=e.prntnode
join #test2 f on e.node=f.prntnode
where a.dealerid=2 and a.dealerlvl=3
I am sure there is a better way to do this with dynamic sql. please help.
Thanks
