Join a row to a table name stored within a column ?

Hi guys - can you tell me if this is doable at all ?
I've an existing table with a lot of data in it that I wish to query on.
This table has a text column, and then 4 more columns - Join Table name, Join column name, Join value and table value column.
The 3 join 3 columns allow me to join this piece of text to a row in another table, identified by the 3 join columns listed above.
Now, I appreciate this is a lousy design, but its in place and there's nothing I can do about it.
I do however need to get a row by row report of the text, followed by the value stored in the column identified by table id column.
So lets say I have
Table_A
Pers_ID
Name
Age
Sex
Table_B
Col_ID
Colour
Hue
My text table will have rows like this
Text
text = 'Person A Age'
join tablename = 'Table_A'
join columnname = 'Pers_ID'
join value = 1
table value column = 'Age'
text = 'Person B Sex'
join tablename = 'Table_A'
join columnname = 'Pers_ID'
join value = 2
table value column = 'Sex'
text = 'Pers A Fave Colour'
join tablename = 'Table_B'
join columnname = 'Col_ID'
join value = 1
table value column = 'Colour'
So - what I should be able to do is go to either table a, and select the column specified, where the id column = the value supplied.
The only way I can think of doing this is to create a temporary table and go through the text table, row by row using pl/sql and select from whatever table it tells me to using dynamic sql and populate the temporary table.
Can this be done using sql ??

Now, I appreciate this is a lousy design, ...I agree. It's a variation of the Entity-Attribute-Value (EAV) model, which might be a good thing if relational databases didn't exist.
I think your present approach, using dynamic SQL, is the best that you can do.
One possible alternative is to unpivot table_a, table_b, and all the other tables like them into an EAV form, then do a UNION of all those unpivoted results. (You could do this in a view, if you wanted to.) Then your query would simply be a join between your text table and the EAV table (or view).
If you'd care to post CREATE TABLE and INSERT statements for a little sample data, and the results you want from that data, then I could demonstrate what I mean.
What version of Oracle are you using? You should always include this when you have a question. It might not matter in this case, but why take a chance?
Here's another approach that would work in very special circumstances.
If there are only a couple of tables like table_a and table_b, and they only have a couple of columns that you might need to reference, then you could do all possible joins, and use CASE expressions to get the results from the one you actually want. All the joins would have to be outer joins, so I expect this approach would be very slow.

Row chaining in table with more than 255 columns

Hi,
I have a table with 1000 columns.
I saw the following citation: "Any table with more then 255 columns will have chained
rows (we break really wide tables up)."
If I insert a row populated with only the first 3 columns (the others are null), is a row chaining occurred?
I tried to insert a row described above and no row chaining occurred.
As I understand, a row chaining occurs in a table with 1000 columns only when the populated data increases
the block size OR when more than 255 columns are populated. Am I right?
Thanks

dyahavYesterday, I stated this on the forum "Tables with more than 255 columns will always have chained rows." My statement needs clarification. It was based on the following:
http://download.oracle.com/docs/cd/B28359_01/server.111/b28318/schema.htm#i4383
"Oracle Database can only store 255 columns in a row piece. Thus, if you insert a row into a table that has 1000 columns, then the database creates 4 row pieces, typically chained over multiple blocks."
And this paraphrase from "Practical Oracle 8i":
V$SYSSTAT will show increasing values for CONTINUED ROW FETCH as table rows are read for tables containing more than 255 columns.
Related information may also be found here:
http://download.oracle.com/docs/cd/B10501_01/server.920/a96524/c11schem.htm
"When a table has more than 255 columns, rows that have data after the 255th column are likely to be chained within the same block. This is called intra-block chaining. A chained row's pieces are chained together using the rowids of the pieces. With intra-block chaining, users receive all the data in the same block. If the row fits in the block, users do not see an effect in I/O performance, because no extra I/O operation is required to retrieve the rest of the row."
http://download.oracle.com/docs/html/B14340_01/data.htm
"For a table with several columns, the key question to consider is the (average) row length, not the number of columns. Having more than 255 columns in a table built with a smaller block size typically results in intrablock chaining.
Oracle stores multiple row pieces in the same block, but the overhead to maintain the column information is minimal as long as all row pieces fit in a single data block. If the rows don't fit in a single data block, you may consider using a larger database block size (or use multiple block sizes in the same database). "
Why not a test case?
Create a test table named T4 with 1000 columns.
With the table created, insert 1,000 rows into the table, populating the first 257 columns each with a random 3 byte string which should result in an average row length of about 771 bytes.

Paraphrase misspelled the view name "V$SYSSTAT", corrected a couple minor typos, and changed "will" to "may" in the closing paragraph as this appears to be the behavior based on the test case.

Need to know schema name and table name associated with a column-URGENT

Hi folks,
I need to know the schema name and the table name associated with a column. Though jdbc has the api to getTableName and getSchemaName, some database vendor like oracle does return empty upon call of mentioned methods. I found that oracle driver does not support that
Can any one give me the solution? It is urgent. Or do you suggest any third pary jdbc driver which can provide those?
Thanks
Angelina

Angelina,
Your question has been discussed several times previously in this forum. Search this forum's archives for "getTableName". Oracle JDBC driver does not implement this (because "it is not feasible" -- according to Oracle).
First of all, I would suggest that you could probably change your application's logic so that you would not need this functionality (but I guess that is not feasible either, right :-)
Alternatively, you could try querying the Oracle database data dictionary.
Good Luck,
Avi.

I want to build the query to retrieve all the Template table records based on the TblmasterTable data for a given id.

This is possible but you need to understand the performance implications of Dynamic SQL before proceeding with this approach.
 
use this logic: 
declare sqlstring varchar2(500):=null 
select 'select stuff from '|| tbl_templatenameid into sqlstring from MasterTable where id=someid; 
execute immediate sqlstring;
 
 
I have really seen very few cases where this approach is justified.

Table name storing freight

Which table stores the sales orders and the corresponding freight charges?
I found table KONV but it doesn't seem to list the correct values for the condition types that I see from TCODE VA03 for a sales order. Some orders are not even found from this table that are founr from VA03.

Hi ,
First of all find out the condition type for Freight being used in the order.
Then go to table VBAK and get the value of field KNUMV( Condition record number).
Then go to table KOMV and enter the KNUMV value in Doc condition field.
and the item number of the item which you want to see the conditions.
If you want to see Freight charge only, enter the condition type for Freight charge in the selection screen of KOMV table.
Now you should be able to see the data.
Hope this answers your question.

Ajai

Field symbols as Table name and in where condition in a select statement

Hello All,
I have a scenario where I need to get user input on table name and old field value and new field value. Then based on user input, I need to select the record from the database. The column name for all the tables in question is different in the database, however there data type is the same and have same values.
I am not able to use a field symbol for comparing the old field value to fetch the relevant record in my where clause.
I cannnot loop through the entire table as it has 10 millilon records, please advice on how to add the where clause as field symbol as the table name is also dynamically assigned.
Here is my code:
DATA: TAB LIKE SY-TNAME,
 TAB_COMP1 LIKE X031L-FIELDNAME,
 TAB_COMP2 LIKE X031L-FIELDNAME,
 NO_OF_FLD TYPE N.
DATA: BEGIN OF BUFFER,
 ALIGNMENT TYPE F,
 C(8000) TYPE C,
 END OF BUFFER.
FIELD-SYMBOLS: <WA> TYPE ANY,
 <COMP1> TYPE ANY,
 <COMP2> TYPE ANY.
GET TABLE NAME GIVEN BY USER IN LOCAL VARIABLE
TAB = TAB_NAME.
CREATE FIELD NAME BASED ON THE TABLE NAME ENTERED.
CASE TAB_NAME.
WHEN 'OIUH_RV_GL'.
 KEY FIELD
 TAB_COMP1 = 'GL_GL_SYS_NO'.
 NO_OF_FLD = 1.
WHEN 'OIUH_RV_OPSL'.
 KEY FIELD
 TAB_COMP1 = 'OPSL_GL_SYS_NO'.
 NO_OF_FLD = 1.
WHEN 'OIUH_RV_OTAX'.
 NOT THE ONLY KEY FIELD
 TAB_COMP1 = 'OTAX_GL_SYS_NO'.
 TAB_COMP2 = 'OTAX_TAX_POS_NO'.
 NO_OF_FLD = 2.
WHEN 'OIUH_RV_GTAX'.
 NOT THE ONLY KEY FIELD
 TAB_COMP1 = 'GTAX_GL_SYS_NO'.
 TAB_COMP2 = 'GTAX_TAX_POS_NO'.
 NO_OF_FLD = 2.
WHEN OTHERS.
 EXIT.
ENDCASE.
SET FIELD SYMBOL WITH APPROPRIATE TYPE TO BUFFER AREA.
ASSIGN BUFFER TO <WA> CASTING TYPE (TAB).
How to add where clause and remove the if condition in the select -- endselect
SELECT * FROM (TAB) INTO <WA>.
ASSIGN COMPONENT TAB_COMP1 OF STRUCTURE <WA> TO <COMP1>.
IF NO_OF_FLD = 2.
 ASSIGN COMPONENT TAB_COMP2 OF STRUCTURE <WA> TO <COMP2>.
ENDIF.
IF <COMP1> = OLD_SYS_NO.
 code for updating table would come here

1. Create single column table for holding field name depending on the table entered.
2. Take input from user: for e.g. table_name
3. Using case load single column table with required fields
 for e.g.
CASE TAB_NAME.
 WHEN 'OIUH_RV_GL'.
 Append 'GL_GL_SYS_NO' to KEY_FIELD --> KEY_FIELD is the single line internal table as mentioned in step 1.
 WHEN 'OIUH_RV_OPSL'.
 Append 'OPSL_GL_SYS_NO'.
 WHEN 'OIUH_RV_OTAX'.
 Append 'OTAX_GL_SYS_NO' to KEY_FIELD.
 APPEND 'OTAX_TAX_POS_NO' to KEY_FIELD.
 WHEN 'OIUH_RV_GTAX'.
 Append 'GTAX_GL_SYS_NO' to KEY_FIELD.
 APPEND 'OTAX_TAX_POS_NO' to KEY_FIELD.
 WHEN OTHERS.
 EXIT.
 ENDCASE.
 Now depending on the table name you have required column ready
4. Create dynamic internal table using following sudo code
 Fill the fieldcatlog using the single column field table and DD03L table, See what all columns from DD03L you want to fill in field catlog table
 loop at internal table with all the fields.
 move it to field catalog.
 append field catalog.
 endloop.
5. Pass this field catalog table to static method create_dynamic_table method
 DATA table TYPE REF TO DATA. --> data object for holding handle to dynamic internal table.
 call method cl_alv_table_create=>create_dynamic_table
 exporting
 it_fieldcatalog = fieldcatalog_tab
 importing
 ep_table = table.
6. Now assign table reference to field symbol of type table.
 ASSIGN table->* to <field-tab>.
7. Also create work area <field-wa> using refrence of table.
 create data object wa LIKE LINE OF <field-tab>.
 ASSIGN wa->* to <field-wa>.
8. Also define field symbol for field name.
 for e.g. <field_name>
4. Dynamic internal table is ready
5. Now execute the select statement as follows:
 SELECT (KEY_FIELD)
 INTO <ITAB> --> created dynamically above
 FROM (TABLE_NAME)
 WHERE (WHERE). --> WHERE is single line internal table having line type of CHAR72. So for every old value there will be one line
 Where condition is same as like we give in static way only difference in this case it will stored in internal table line wise.
 In this case you need to append all your where condition line by line in to WHERE.
5. To fill this dynamic internal table using ASSIGN COMPONENT <Comp_number> OF STRUCTURE <field-wa> TO <field-name>
 So in this case if first field of structure STRUCT1 is user_id then sudo-code will be
 loop at internal table containing list of fields into field_wa --> single column field table
 ASSIGN COMPONENT field_wa OF STRUCTURE <field-wa> TO <field>. "Here field_wa is wa area for single column internal table holding all the fieldnames.
 Now <field-name> points to user_id field. Move some value into it as nornally we do with variables.
 Move <your_new_value> to <field-name>. --> Assign new value
 or
 <field-name> = <your_new_value>.
 Endloop.
6. After completing all the fields one row will be ready in <field_wa>.
 APPEND <field_wa> to <field_tab>.
Hope this helps you.
Thanks,
Augustin.

GL Table Name Require

Hi Nilesh,
You can not find this information in one single table. Please try the below easiest method to get information:
Execute transaction SQVI
Give some name and create
Pop Up apprears, give titile and in Data Source select, table join
Press Shift+F1
Give table name BKPF
Press Shift+F1 again
Give table name as SBIS or BSAS depending upon the requirement to get clear item or open items
Press back butto
Expand the nodes in left side of screen
Select the items based on which you want to extract the data from table and select the filed for output which you wnat to see in ouput

Obtaining qualifier and table name in describe

Determining qualifier and table name in describe
Is there a way in OCIParamGet() on a statement handle/OCIAttrGet() sequence to determine the qualifier and table name?
Otherwise, how can I get this information?
When doing a join and listing the columns, we would like to be able to list qual.table name, followed by the columns associated with that table.

If not with the parameter attributes (whic I haven't checked) you can always use the DescribeAny() to get the information.
If you need I can get you a fairly complete sample for DescribeAny() which demonstrates describing just about every type of schema item.

Updating one row updates every row in the table

I'm having a weird problem in which I insert a row into a table, select that row, and update its columns, and all the rows in the table end up with those columns all set to the new value. Like this:
A B C
1 4 7
2 3 8
9 6 7
Statement s1 = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE);
s1.execute("INSERT INTO table (A) VALUES (5)");
Statement s2 = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE);
RecordSet rs = s2.executeQuery("SELECT * FROM table WHERE A=5");
if (rs.next()) {
rs.updateInt("B", 4);
rs.updateInt("C", 6);
rs.updateRow();
A B C
1 4 6
2 4 6
9 4 6
5 4 6I'm using Mac OS X 10.4.9, OpenBase Solo 10.0.5, and Java 1.5. I hope someone has experienced this before because it has me befuddled.

OpenBase powers Apple's online store, so I wouldn't think that's the problem. I'm placing all the blame on the JDBC driver.
Funnily, I started updating ResultSets that way because executing UPDATE statements directly gave me this problem before. Doing it this way made the problem go away, until now.
I tried replacing the INSERT with two fields with one with all the fields, and now it throws a SQL error that is most definitely bogus:
java.sql.SQLException: SQL ERROR - [position 569, near '' in ', 0, 0, 0, ''] insert error: comma expected but not found in data.
SQL: INSERT INTO characters (UniqueID, CodePoint, NameFirst, NameMiddle, NameLast, NameMaiden, NameCommFirst,
NameCommMiddle, NameCommLast, NameCommFull, Title, Classification, Subclassification, Considerable, SexString,
TransitionString, GenderString, OrientationString, TitleString, PronounString, SGO, BirthDay, BirthMonth, BirthYear,
Generation, FirstOfSet, ParentBio, Parent1, Parent2, Parent3, ParentBioType, Parent1Type, Parent2Type, Parent3Type)
VALUES ('bomb', 123, 'Ziggy', 'Boogy', 'Doog', '', '', '', '', '', '', -1, -1, 1, '', '', '', '', '', '', 0, 0, 0, 0, 0, '', '', '', '', '', 0, 0, 0, 0)Bogus because there are the same number of data items as field names, and position 569 is a comma.
At this point I have to ask myself why I ever chose OpenBase in the first place. (That's right, I had a RealBasic plugin for it. shudders) I'm sure OpenBase itself is fine, but its JDBC driver is trash. MySQL here I come.

I have more than 500 tables in my database.
'insert_date' & update_date column is found in more
than 100 tables with data type as date.
I need a query to list all table names and
'insert_date' column's content.What do you mean by "column's content". A table can have many rows. Do you want to display all the distinct value for these columns?
Below is the query to get the tables which has columns insert_Date and update_date
select table_name
from user_tab_columns
where column_name ='INSERT_DATE'
or column_name ='UPDATE_DATE'
/You can write a PL/SQL block to retrive the distinct values of INSERT_DATE for these tables
declare
TYPE ref_cur IS REF CURSOR;
insert_date_cur ref_cur;
lv_insert_date DATE;
cursor tables_list IS
select table_name
from user_tab_columns
where column_name ='INSERT_DATE';
begin
for cur_tables in tables_list
loop
OPEN insert_date_cur for 'SELECT DISTINCT insert_date from '||cur_tables.table_name;
DBMS_OUTPUT.PUT_LINE(cur_tables.table_name);
DBMS_OUTPUT.PUT_LINE('--------------------------------');
LOOP
FETCH insert_date_cur into lv_insert_date;
EXIT WHEN insert_date_cur%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(lv_insert_date);
END LOOP;
CLOSE insert_date_cur;
end loop;
end;I haven't tested this code. There might be some errors. Just posted something to start with for you.

Invalid table name error ....

Hi,
I have written a function which takes table name dynamically and if column emp_id is null for more than 0 records then 1 is returned else 0 .
My problem is when i compile iam getting invalid table name error .
Below is my function :
create or replace
FUNCTION f_table ( tab_name in varchar2 ) return number is
l_count number;
begin
select count(*) into l_count from tab_name where emp_id is null;
if l_count >0 then
return 1;
else
return 0;
end if;
end;
Please help ...
Thanks in advance ..

Looks fine to me, you could use sign() for the last part:
CREATE OR REPLACE FUNCTION f_table (tab_name IN VARCHAR2)
RETURN NUMBER
IS
l_count NUMBER;
v_sql VARCHAR2 (2000);
BEGIN
v_sql := 'SELECT COUNT (*) FROM ' || tab_name || ' WHERE emp_id IS NULL';
EXECUTE IMMEDIATE v_sql
INTO l_count;
RETURN sign(l_count);
END;And if you have large tables, you could consider not counting it all, and do something like this:
CREATE OR REPLACE FUNCTION f_table (tab_name IN VARCHAR2)
RETURN NUMBER
IS
l_count NUMBER;
v_sql VARCHAR2 (2000);
BEGIN
v_sql := 'SELECT COUNT (*) FROM ' || tab_name || ' WHERE emp_id IS NULL AND rownum = 1';
EXECUTE IMMEDIATE v_sql
INTO l_count;
RETURN l_count;
END;Regards

Need to know schema and table name

Hi folks,
I need to know the schema name and the table name associated with a column. Though jdbc has the api to getTableName and getSchemaName, some database vendor like oracle does return empty upon call of mentioned methods. I found that oracle driver does not support that ��
Can any one give me the solution? It is urgent. Or do you suggest any third pary jdbc driver which can provide those?
Thanks
Angelina
