SQL for joins

I have 2 tables - customer and order. I am looking to test some join strategies (block nested loop, sort-merge and hash). Could anyone tell me the sql code to perform the joins.

Hi amanda,
Nested Loop: this join is used when you have indexes defined on the join columns. you can use the hint USE_NL.
select /*+ ORDERED USE_NL(b) */ customer_no , order_no
from order a, customer b
where a.customer_no = b.customer_no;
Sort-Merge: suppress the indexes then you shld be able to use sort-merger join or use the hint USE_MERGE, this shld force a sort-merger join.
select /*+ ORDERED USE_MERGE(b) */ customer_no , order_no
from order a, customer b
where a.customer_no = b.customer_no;
Hash Join: use the USE_HASH hint in the query to force the hash join. make sure you have has_area_size parameter set to a value like
700k depending on the memory availability in your machine.hash join builds the hash value of the customer_no from cutomer table in memory and searches for matching records in the order table this is used if you have more memory in your machine.
select /* ORDERED USE_HASH(b) */ customer_no , order_no
from order a, customer b
where a.customer_no = b.customer_no;
may be you can grab some oracle books on sql tuning they explain in great detail about the hints and joins.

SQL for join table problem?

hi morning,
my problem also haven find out the solution,can help me solve.
I got one part of register student to exam,during that part is like that.
Student Code:________(table3)
Exam Code:_________(table 3)
Student Name:________(table 1)
Exam Name:_________(table 2)
I can write code call table 3 but when three table join together in part 3,got problem is come out alry....The problem is inside the Student Name & Exam Name.When i use the button for NEXTRECORD to check record,cannot call the student Name & exam Name.
Thank for help. Because i use sql code to call table 3 to check table1 and table 2 detail ,then retrive that data.
my code is like that,

Can we implement the custom sql query in CR for joining the two tables

Hi All,
Is there anyway to implement the custom sql query in CR for joining the two tables?
My requirement here is I need to write sql logics for joining the two tables...
Thanks,
Gana

In the Database Expert, expand the Create New Connection folder and browse the subfolders to locate your data source.
Log on to your data source if necessary.
Under your data source, double-click the Add Command node.
In the Add Command to Report dialog box, enter an appropriate query/command for the data source you have opened.
For example:
SELECT
    Customer.`Customer ID`,
    Customer.`Customer Name`,
    Customer.`Last Year's Sales`,
    Customer.`Region`,
    Customer.`Country`,
    Orders.`Order Amount`,
    Orders.`Customer ID`,
    Orders.`Order Date`
FROM
    Customer Customer INNER JOIN Orders Orders ON
        Customer.`Customer ID` = Orders.`Customer ID`
WHERE
    (Customer.`Country` = 'USA' OR
    Customer.`Country` = 'Canada') AND
    Customer.`Last Year's Sales` < 10000.
ORDER BY
    Customer.`Country` ASC,
    Customer.`Region` ASC
Note: The use of double or single quotes (and other SQL syntax) is determined by the database driver used by your report. You must, however, manually add the quotes and other elements of the syntax as you create the command.
Optionally, you can create a parameter for your command by clicking Create and entering information in the Command Parameter dialog box.
For more information about creating parameters, see To create a parameter for a command object.
Click OK.
You are returned to the Report Designer. In the Field Explorer, under Database Fields, a Command table appears listing the database fields you specified.
Note:
To construct the virtual table from your Command, the command must be executed once. If the command has parameters, you will be prompted to enter values for each one.
By default, your command is called Command. You can change its alias by selecting it and pressing F2.

Forming generic sql query   for joining multiple sap tables in ABAp

Hi,
I am new to this abap field ,facing an issue onsap-jco project . I have used RFC_READ_TABLE FM ,Customized this FM but facing an issue how to write generic open SQl select statement for joining multiple tables using RFC_READ_TABLE .Kindly help on this issue.
Thanks.

something like this? If your tuples are not single columns, then you'll have to use dynamic sql to achieve the same result.with
table_1 as
(select '|Xyz|Abc|Def|' tuple from dual
table_2 as
(select '|Data1|Data21|Data31|Data41|Data51|' tuple from dual union all
select '|Data2|Data22|Data32|Data42|Data52|' tuple from dual union all
select '|Data3|Data23|Data33|Data43|Data53|' tuple from dual union all
select '|Data4|Data24|Data34|Data44|Data54|' tuple from dual union all
select '|Data5|Data25|Data35|Data45|Data55|' tuple from dual
select case the_row when 1
                    then tuple
                    else '|---|---|' || substr(tuple,instr(tuple,'|',1,3) + 1)
       end tuple
from (select substr(a.tuple,instr(a.tuple,'|',:one_one),instr(a.tuple,'|',:one_one + 1)) ||
               substr(a.tuple,instr(a.tuple,'|',1,:one_two) + 1,instr(a.tuple,'|',1,:one_two + 1) - instr(a.tuple,'|',1,:one_two)) ||
               substr(b.tuple,instr(b.tuple,'|',1,:two_one) + 1,instr(b.tuple,'|',1,:two_one + 1) - instr(b.tuple,'|',1,:two_one)) ||
               substr(b.tuple,instr(b.tuple,'|',1,:two_two) + 1,instr(b.tuple,'|',1,:two_two + 1) - instr(b.tuple,'|',1,:two_two)) tuple,
               rownum the_row
          from table_1 a,table_2 b

ORA-01489 Received Generating SQL for Report Region

I am new to Apex and I am running into an issue with an report region I am puzzled by. Just a foreword, I'm sure this hack solution will get a good share of facepalms and chuckles from those with far more experience. I welcome suggestions and criticism that are helpful and edifying!
I am on Apex 4.0.2.00.07 running on 10g, I believe R2.
A little background, my customer has asked an Excel spreadsheet be converted into a database application. As part of the transition they would like an export from the database that is in the same format as the current spreadsheet. Because the column count in this export is dynmic based on the number of records in a specific table, I decided to create a temporary table for the export. The column names in this temp table are based on a "name" column from the same data table so I end up with columns named 'REC_NAME A', 'REC_NAME B', etc. (e.g. Alpha Record, Papa Record, Echo Record, X-Ray Record). The column count is currently ~350 for the spreadsheet version.
Because the column count is so large and the column names are dynamic I've run into a host of challenges and errors creating this export. I am a contractor in a corporate environmentm, so making changes to the apex environment or installation is beyond my influence and really beyond what could be justified by this single requirement for this project. I have tried procedures and apex plug-ins for generating the file however the UTL_FILE package is not available to me. I am currently generating the SQL for the query in a function and returning it to the report region in a single column (the user will be doing a text-to-column conversion later). The data is successfully being generated, however, the sql for the headers is where I am stumped.
At first I thought it was because I returned both queries as one and they were joined with a 'union all'. However, after looking closer, the SQL being returned for the headers is about +10K+ characters long. The SQL being returned for the data is about +14k+. As mentioned above, the data is being generated and exported, however when I generate the SQL for the headers I am receiving a report error with "ORA-01489: result of string concatenation is too long" in the file. I am puzzled why a shorter string is generating this message. I took the function from both pages and ran them in a SQL command prompt and both return their string values without errors.
I'm hopeful that it's something obvious and noobish that I'm overlooking.
here is the code:
data SQL function:
declare
l_tbl varchar2(20);
l_ret varchar2(32767);
l_c number := 0;
l_dlim varchar2(3) := '''|''';
begin
l_tbl := 'EXPORT_STEP';
l_ret := 'select ';
for rec in (select column_name from user_tab_columns where table_name = l_tbl order by column_id)
loop
    if l_c = 1 then
        l_ret := l_ret || '||' || l_dlim || '|| to_char("'||rec.column_name||'")';
    else
        l_c := 1;
        l_ret := l_ret || ' to_char("' || rec.column_name || '")';
    end if;
end loop;
    l_ret := l_ret || ' from ' || l_tbl;
dbms_output.put_line(l_ret);
end;header sql function:
declare
l_tbl varchar2(20);
l_ret varchar2(32767);
l_c number := 0;
l_dlim varchar2(3) := '''|''';
begin
l_tbl := 'EXPORT_STEP';
for rec in (select column_name from user_tab_columns where table_name = l_tbl order by column_id)
loop
    if l_c = 1 then
        l_ret := l_ret || '||' || l_dlim || '||'''||rec.column_name||'''';
    else
        l_c := 1;
        l_ret := l_ret || '''' || rec.column_name || '''';
    end if;
end loop;
    l_ret := l_ret || ' from dual';
dbms_output.put_line(l_ret);
end;-------
EDIT: just a comment on the complexity of this export, each record in the back-end table adds 12 columns to my export table. Those 12 columns are coming from 5 different tables and are the product of a set of functions calculating or looking up their values. This is export is really a pivot table based on the records in another table.

Thank you, Denes, for looking into my issue. I appreciate your time!
It is unfortunately a business requirement. My customer has required that the data we are migrating to this app from a spreadsheet be exported in the same format, albeit temporarily. I still must meet the requirement. I'm working around the 350 columns by dumping everything into a single column, which is working for the data, however, the headers export is throwing the 01489 error. I did run into the error you posted in your reply. I attempted to work around it with the clob type but eneded up running into my string concatentation error again.
I'm open to any suggestions at this point given that I have the data. I'm so close because the data is exporting, but because the columns are dynamic, the export does me little good without the headers to go along with it.

What is a efficient SQL for this query ?

Hi,
I am using 9.2 database. Suppose I am having following 2 tables
Table p having only one column i.e. 'a'. Values in this column are
a1
b1
c1
d1
Table Q having three columns a, b, c
a1, 1, 100
a1, 2, 50
b1, 1, 30
b1, 2, 40
d1, 2, 90
Table Q can be joined only using column a.
Table Q can have multiple or no records for column a in table p. Based on above sample data, I want following output
a1, 100, 50
b1, 30, 40
c1
d1, 90
Kindly tell be how can I achive this in most efiicient way !!!
thanks & regards
PJP

I only have you two tracks about how do it.
If you want all the columns from p with or wihout q you have to do:
11:35:58 SQL> l
1 select p.*, q.*
2 from p,q
3* where p.a = q.a (+)
11:37:27 SQL> /
For change the order of the colums for rows you can see the url, the are more examples like that only need to search "columns for rows" in this forums.
Anyway:
with rt as
select 'a1' a, 1 b, 100 c from dual union
select 'a1', 2, 50 from dual union
select 'b1', 1, 30 from dual union
select 'b1', 2, 40 from dual union
select 'd1', 2, 90 from dual)
--select * from rt
select a, decode('1','0','0',rtrim(xmlagg(xmlelement(b, b || ',')).extract('//text()'),',')) b
, decode('1','0','0',rtrim(xmlagg(xmlelement(c, c || ',')).extract('//text()'),','))
from rt
group by a

Other way:
select a, ltrim(b,',') as b, ltrim(c,',') as c
from (
select row_number() over (partition by a order by length(b) desc) as rn, a, b,c
from (select a, sys_connect_by_path(b, ',') as b,
sys_connect_by_path(c, ',') as c
from (
select row_number() over (partition by a order by b) as rn, a, b,c
from rt) y
connect by rn = prior rn + 1 and prior a = a
start with rn = 1
where rn = 1

Correlated Subquery for joining summary table original data table

I want to list a set of fields from an inner-query that correspond to calculated fields on an outer-query. A set of date fields on the outer-query signify a range to correlate records on the inner-query. Records on the inner-query have a single date field
which should fall within the outer-query date range. At this point, I cannot determined the correct syntax for this query, but am able to achieve the desired results using a left outer join and case-when arguments on what should be the inner-query records.
Here's my basic SQL right now:
SELECT DISTINCT a.service,
  a.start_range, -- start of month
  a.end_range, -- end of month
a.availability,
  CASE WHEN YEAR(a.start)=YEAR(o.begin) AND MONTH(a.start)=month(o.begin) THEN o.event_id ELSE NULL END AS 'event_id'
CASE WHEN YEAR(a.start)=YEAR(o.begin) AND MONTH(a.start)=month(o.begin) THEN o.minutes ELSE NULL END AS 'minutes'
FROM service_availability a LEFT OUTER JOIN
service_outage o ON
a.service=o.service AND
TIMESTAMPDIFF(YEAR,o.begin,NOW())=0
WHERE TIMESTAMPDIFF(YEAR,a.start,NOW())=0
The limitation with this approach is that the CASE WHEN argument needs to be used for retrieving any fields on the service_outage table. I've tried several approaches including parameters in both the FROM and
WHERE clauses as well as subqueries, but cannot get any to return the data. Is there a better way to achieve this?

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your datA. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal datA. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL.
>> I want to list a set of fields[sic] from an inner-query that correspond to calculated fields [sic] on an outer-query. <<
Columns are not fields. Rows are not records. CASE is an expression, not an argument. Where did you get the terms “inner-query” and “outer-query”? I never heard them before and I have some experience with SQL. We have subqueries; is that what you are trying
say?
>> A set of date fields [sic] on the outer-query signify a range to correlate records [sic] on the inner-query. Records on the inner-query have a single date field [sic] which should fall within the outer-query date range.<<
You do not know the basic terms or how SQL work. You also posted some weird dialect of an SQL-like language. What is NOW()?? Does that mean CURRENT_TIMESTAMP in your dialect? Did you know that BEGIN is a reserved word in SQL?
>> At this point, I cannot determined the correct syntax for this query, but am able to achieve the desired results using a LEFT OUTER JOIN and CASE-when arguments [sic] on what should be the inner-query [sic] records [sic]. Here's my basic SQL right
now: <<
Why are you doing temporal math in SQL? Where is the calendar and report period tables?
Since SQL is a database language, we prefer to do look ups and not calculations. They can be optimized while temporal math messes up optimization. A useful idiom is a report period calendar that everyone uses so there is no way to get disagreements in the DML.
The report period table gives a name to a range of dates that is common to the entire enterprise.
CREATE TABLE Month_Periods
(month_name CHAR(10) NOT NULL PRIMARY KEY
CHECK (month_name LIKE '[12][0-9][0-9][0-9]-[01][0-9]-00'),
month_start_date DATE NOT NULL,
month_end_date DATE NOT NULL,
CONSTRAINT date_ordering
CHECK (month_start_date <= month_end_date),
etc);
These report periods can overlap or have gaps. I like the MySQL convention of using double zeroes for months and years, That is 'yyyy-mm-00' for a month within a year and 'yyyy-00-00' for the whole year. The advantages are that it will sort with the ISO-8601
data format required by Standard SQL and it is language independent. The pattern for validation is '[12][0-9][0-9][0-9]-00-00' and '[12][0-9][0-9][0-9]-[01][0-9]-00'
Why is an outage not an availability status or an event?
>> The limitation with this approach is that the CASE WHEN argument [sic] needs to be used for retrieving [sic: querying is not retrieving] any fields [sic] on the Service_Outage table<<
We have no DDL! Not even sample data.
>> I've tried several approaches including parameters in both the FROM and WHERE clauses as well as subqueries, but cannot get any to return the data. <<
Parameters exist in procedure declarations; arguments are the actual values passed in them. Neither of them as anything to do with a query.

Sql to JOIN 3 tables

I need some help on my sql to join 3 tables.
I am close, but my results come out to be a multiple of what im supposed to get.
I am trying to retrieve a sum from table 2 and table 3.
there are 4 records in table2 and 3 records in table3
the results SHOULD be 3 and 20
but i get 12/60
which is a number i shoudl get times the #records of the oppposite table.
i have moved my code in different arrangements to see if that is the issue, but it doesnt seem to matter. i still get the result of a multiple.
Heres my code so far:
SELECT sum(table3.field) AS sumtable3, sum(table3.field) AS sumtable2
FROM table1
LEFT JOIN table2 ON table1.id=table2.id
LEFT JOIN table3 ON table2.id=table3.id
GROUP BY table1.id
ORDER BY table1.id

Please provide sample data for all 3 tables.

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
FROM AdventureWorks2012.HumanResources.Employee
WHERE BusinessEntityID = @BusinessEntityID';
SET @ParmDefinition = N'@BusinessEntityID tinyint';
/* Execute the string with the first parameter value. */
SET @IntVariable = 197;
EXECUTE sp_executesql @SQLString, @ParmDefinition,
@BusinessEntityID = @IntVariable;
/* Execute the same string with the second parameter value. */
SET @IntVariable = 109;
EXECUTE sp_executesql @SQLString, @ParmDefinition,
@BusinessEntityID = @IntVariable;
Basically any query can be run as dynamic SQL. However, static SQL is the first choice. Use dynamic SQL if needed.

SQL for pulling description from product identification section off of summ

I tried using the DB schema tool to generate sql for pullling the Description field off of the Product Indentification section on the summary tab and it came up with zero records even though i know we have a few 1,000 specs that use that field.
Can you send me the sql that i should be using or the table to look in to find that text??
thanks,
David

This should get you started,
select
ss.SpecNumber as "Spec Number"
, ssn.name as "Spec Name"
, sdftp.Description as "Description"
from SpecDescriptionFreeTextProp sdftp
inner join gsmProductIdentification gpi on sdftp.fkSpecID = gpi.pkid
inner join SpecSummary ss on gpi.fkSpecID = ss.SpecID
inner join SpecSummaryName ssn on ssn.fkSpecsummary = ss.PKID
where
ssn.langid = 0

;That's still hard to read.
You may have noticed that this site normally compresses whitespace.
Whenever you post formatted text (including, but not limited to, code) on this site, type these 6 characters:
\(small letters only, inside curly brackets) before and after each section of formatted text, to preserve spacing. Blushadow probably won't do it for you every time you post a message.
This is just one of the many things mentioned in the forum FAQ {message:id=9360002} that can help you get better answers sooner.
Are you still having a problem? Have you tried using in-line views? If so, wouldn't it make more sense to post the code you're using, rather than some code you're not using?

Looking For Free Good Tutorial To Learn SQL For 8i

Hello all,
I am looking for a free good tutorial to learn SQL for Oracle 8i.
If anyone got any links or resources, kindly suggest.
Thanks in advance.

I am looking for a free good tutorial to learn SQL for Oracle 8i.8i has been unsupported for years. If you're just starting out, you might as well learn the latest.

BREAK not working in SQL+ for windows. Works in SQL+ in DOS

I'm writing a simple query in SQL+
SELECT table_name, column_name
FROM user_tab_columns
WHERE table_name like 'MYTAB%'I first set BREAK ON table_name
then I run my query.
I expect the table name to be shown once, per table, not once per column.
If I run this query in SQL+ in a DOS window, that's exactly what happens.
If I run the same thing in SQL+ for Windows (version 10 on an 11g db) the break command appears to be ignored.
Any ideas ??
Thanks folks.

Not sure but maybe try the NODUPLICATES option.
break on table_name noduplicates

Need help with SQL for Pie Chart

I am trying to create a pie charge which would have 3 slices.
Following sql gives me the expected values when I run the sql command:
select
round(avg(CATEGORY_1 + CATEGORY_2 + CATEGORY_3 + CATEGORY_4 + CATEGORY_5),0) "OD Engagements",
round(avg(CATEGORY_6 + CATEGORY_7 + CATEGORY_13),0) "Talent Engagements",
round(avg(CATEGORY_8 + CATEGORY_9 + CATEGORY_10 + CATEGORY_11 + CATEGORY_12),0) "Other Engagements"
from OTD_PROJECT
where STATUS in ('Open','Hold')
I get 3 columns labeled: OD Engagements, Talent Engagements and Other Engagements with the correct averages based on the the data.
I have tried several ways to try to get this to work in the SQL for a pie chart, but keep getting the invalid sql message and it won't save. I also tried saving without validation, but no data is shown on the chart at all.
I want to have a pie, with 3 slices, one labeled OD Engagements with a value of 27, one labeled Talent Engagements with a value of 43 and one labeled Other Engagements with a value of 30. Then I want to be able to click on each pie slice to drill down to a secondary pie chart that shows the breakdown based on the categories included in that type.
Since I am not grouping based on an existing field I an unsure what the link and label values should be in the chart sql.

You'll need something like the below. I have no idea what the URL for the drilldown needs to be. It should create an appropriate link in your app for the particular slice. Mainly the code below breaks the SQL results into three rows rather than three columns. It may well have a syntax error since I can't test.
select linkval AS LINK,
       title    AS LABEL,
       calc_val AS VALUE
FROM   (SELECT 'OD Engagements' AS title,
               round(avg(CATEGORY_1 + CATEGORY_2 + CATEGORY_3 + CATEGORY_4 + CATEGORY_5),0) AS calc_val,
               'f?p=???:???:' || v('APP_SESSION') || '::NO:?' AS LINKVAL
        from   OTD_PROJECT
        where STATUS in ('Open','Hold')
        UNION ALL
        SELECT 'Talent Engagements' AS title,
               round(avg(CATEGORY_6 + CATEGORY_7 + CATEGORY_13),0) AS calc_val,
               'f?p=???:???:' || v('APP_SESSION') || '::NO:?' AS LINKVAL
        from   OTD_PROJECT
        where STATUS in ('Open','Hold')
        UNION ALL
        SELECT 'Other Engagements' AS title,
               round(avg(CATEGORY_8 + CATEGORY_9 + CATEGORY_10 + CATEGORY_11 + CATEGORY_12),0) AS calc_val,
               'f?p=???:???:' || v('APP_SESSION') || '::NO:?' AS LINKVAL
        from   OTD_PROJECT
        where STATUS in ('Open','Hold')
       );

Could we use embedded SQL for XML in .pc ?

Hi,
Can we use embedded SQL for XML in .pc ?
<1> assume we have run SQL statements in Oracle9i:
SQL>create table MY_XML_TABLE
(Key1 NUMBER,
Xml_Column SYS.XMLTYPE);
SQL>insert into MY_XML_TABLE(key1, Xml_Column) values
(1, SYS.XMLTYPE.CREATEXML
('<book>
<chapter num="1">
<text>This is the my text</text>
</chapter>
<book>')
<2> Could we directly translate it in .pc as usually:
<outlined, not exactly)
int emp_number = 1;
XML_Data emprec; /* ?????? */
EXEC SQL SELECT M.Xml_Column.GETCLOBVAL() as XML_Data
INTO :emprec INDICATOR :emprec_ind
FROM MY_XML_TABLE M
WHERE Key1 = :emp_number;
Thanks
MJ

reply by myself.
No problem!!
===============================
int emp_number = 1;
struct emprec{
char feature[1280]
EXEC SQL SELECT M.Xml_Column.GETCLOBVAL() as XML_Data
INTO :emprec INDICATOR :emprec_ind
FROM MY_XML_TABLE M
WHERE Key1 = :emp_number;

SQL for joins
