[php+mysql] how to use variables in a select statement?

Hi all,
I'm searching for a way to use a variable in the select
statement of mysql
query.
I have this variable that can contain:
$var=field_1 field_2 field5
or
$var=field3 field4 field8
so, the variable content is not always the same.
I would like to filter a table selecting only the columns
specified by the
current $var content.
Is this possible to do something like this?
$var=field1 field5 field10
SELECT string_to_array($var)
FROM mytable
ORDER BY mysortfield ASC
Or, is there another way to select columns dynamically?
Thanks for any suggestion.

Using Variables in a select statement through a Database Adapter

I was wondering how I reference a variable in a select statement through a Database Adapter.
Ex.
1. I have a global variable that stores an employee number
2. I want to select an SSN # from a table based on an employee #
variable.
select ssn from emp where ssn = :input_variable - ????
- how do i reference the variable - I am getting a 'missing IN or OUT parameter error?
Any advice is much appreciated.
~Thanks

I'm just wondering if anyone knows a work around so that I might be able to store a Table's FIELD name in a variable or an array[] so that I can do a query based on the decision of a loop without having to code 10 IF/ELSE statements.For instance, although the above code will not work, this code, although quite lengthy, does:
If DataGrid1.SelStartCol = 0 Then
Adodc1.RecordSource = "Select * from tblReservation order by RES__PUR_DT"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 1 Then
Adodc1.RecordSource = "Select * from tblReservation order by VENDOR"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 2 Then
Adodc1.RecordSource = "Select * from tblReservation order by VEN_LOC"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 3 Then
Adodc1.RecordSource = "Select * from tblReservation order by RES_TYPE"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 4 Then
Adodc1.RecordSource = "Select * from tblReservation order by RES_FROM_DT"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 5 Then
Adodc1.RecordSource = "Select * from tblReservation order by RES_TO_DT"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 6 Then
Adodc1.RecordSource = "Select * from tblReservation order by MISC_ADJ"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 7 Then
Adodc1.RecordSource = "Select * from tblReservation order by STATE_TAX"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 8 Then
Adodc1.RecordSource = "Select * from tblReservation order by LOC_CHARGE"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 9 Then
Adodc1.RecordSource = "Select * from tblReservation order by RES_ID"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 10 Then
Adodc1.RecordSource = "Select * from tblReservation order by RES_OP"
Adodc1.Refresh
End If
Do you see where i'm going with this?
I simple want to use a variable in the "select * from <Table> Order by <Field>"

How to use SET ID in select statement of SQ02

Hi,
I have a infoset, where for one of my Zfield, i have writen a select statement in order to get my ouput.
if aufk-aufnr = 'XYZ'.
select sum( FKBTR ) from fmifiit into zfmifiit
where fikrs = aufk-kokrs
and fipex IN capex
and wrttp NE '51'.
endif.
For the above statement, i have created (with 10 single values, table name FMCI, field name FIPEX) a SET id named CAPEX and used with IN operator.
But when i generating the infoset i am getting error like below
The IN operator with "CAPEX" is followed neither by an internal table nor by a value list
I was using IN opeartor for set ids during validation / substitutions, where if i have to validate multiple single values.
What to do here?

You have to convert the set to a selection table in an ABAP coding before using it in a SELECT statement.
(Check FM like G_SET_TREE_IMPORT to import definition of set (values and intervals) and map them to a select-table, or ask a developper to perform it, look at G_SET_TREE_IMPORT -> select statement)

as first table /sal../lclic primary key is guid_lclic
and it is joined to table
legcon by guid_lclci ( not a primary key here)
legcon primary key is guid_legcon
and table 3 legsv by lgreg (pk here)

I WANT TO REDUCE IS LET ME KNOW ON WHAT fields i need to use delete adjacen duplicates
or use comparing all fields?

hi sudha
if u see my select statement is contains four Primary keys
srvll
lgreg
ctsty
guid_lclic
but the next table connected to this table legcon is by guid_pobj and anothe table by guid_mobj
and if i take this gt_sagmeld to another temp table and i find abt 10 lakh uniques guid_pobj
similary 6 lakh guid_mobj so the next slect is hanpering because of this
not COMING TO OUR POINT IF I SORT ONLY BY OUR PRIMARY KEYS NOT TAKING INTO ACCOUNT TEH GUID_POBJ AND GUID_MOBJ
THE ENTRIES ARE VERY LESS BUT IF I TAKE INOT ACCCOUNT IN GT_SAGMELD THE ENTRIES ARE ABT 20 LAKH
SO I AM NOT SURE WHETHER TO TAKNE GUID_POBJ AND GUID_MOBJ INOT ACCOUNT FOR DELECTING ADJACENT DUPLICATES?
HENCE THE QUESTION OF ON WHICH FIRLD DELETE OR COMPARING ALL FIELDS I USE?

Hi ,
You can check this and change your code by taking this as an example. I just noted down with simple one input and return as collection type
and how to use/call it in select statement.

How to use variables with

I need to get the number of lines in internal table, which would
be easy, using DESCRIBE TABLE itab LINES lines. But the problem
is, that I get the name of this internal table in the field of
another internal table, so I have to use the name of internal
table as variable, but I don't know how to use variables with
DESCRIBE TABLE (or if this is possible).

Hi,
REPORT ZPRUEBA782 .
define two tables with diferent structures.
data: begin of table1 occurs 0,
registro type i,
end of table1.
data: begin of table2 occurs 0,
registro type i,
repid like sy-repid,
end of table2.
data: rows type i.
start-of-selection.
fill them with data
do 1000 times.
table1-registro = sy-tabix.
append table1.
enddo.
do 1757 times.
table2-registro = sy-tabix.
table2-repid = sy-repid.
append table2.
enddo.
call a form that receives as input the table and returns the number
of rows as output.
perform howmanyrows tables table2 changing rows.
break-point. "evaluate the number of rows
perform howmanyrows tables table1 changing rows.
break-point. "evaluate the number of rows
end-of-selection.
form howmanyrows tables itable changing rows.
rows = 0.
loop at itable.
add 1 to rows.
endloop.
endform.
You can try it if you don't find a better solution.

yes, my Data source is SAP BW, and connected to BOE via SAP INT KIT.
It's too bad that SAP doesn't support so simple requirement.
you said : user exit
are used to address these needs.
so there are possibility to solve my problem.
would you give me the logic of user exit? which part I should create the user exit
I'm quiet familiar with user exit in BW

How to use bind variable in this select statement

Hi,
I have created this procedure where table name and fieldname is variable as they vary, therefore i passed them as parameter. This procedure will trim leading (.) if first five char is '.THE''. The procedure performs the required task. I want to make select statement with bind variable is there any possibility to use a bind variable in this select statement.
the procedure is given below:
create or replace procedure test(tablename in varchar2, fieldname IN varchar2)
authid current_user
is
type poicurtype is ref cursor;
poi_cur poicurtype;
sqlst varchar2(250);
THEVALUE NUMBER;
begin
     sqlst:='SELECT EMPNO FROM '||TABLENAME||' WHERE SUBSTR('||FIELDNAME||',1,5)=''.THE ''';
     DBMS_OUTPUT.PUT_LINE(SQLST);
OPEN POI_CUR FOR SQLST ;
LOOP
     FETCH POI_CUR INTO THEVALUE;
          EXIT WHEN POI_CUR%NOTFOUND;
          DBMS_OUTPUT.PUT_LINE(THEVALUE);
          SQLST:='UPDATE '||TABLENAME|| ' SET '||FIELDNAME||'=LTRIM('||FIELDNAME||',''.'')';
          SQLST:=SQLST|| ' WHERE EMPNO=:X';
          DBMS_OUTPUT.PUT_LINE(SQLST);
               EXECUTE IMMEDIATE SQLST USING THEVALUE;
END LOOP;
COMMIT;
END TEST;
Best Regards,

So you want to amend each row individually? Is there some reason you're trying to make this procedure run as slow as possible?
create or replace procedure test (tablename in varchar2, fieldname in varchar2)
authid current_user
is
   sqlst      varchar2 (250);
   thevalue   number := 1234;
begin
   sqlst := 'update ' || tablename || ' set ' || fieldname || '= ltrim(' || fieldname || ',''.'') where substr(' || fieldname
      || ',1,5) = ''.THE ''';
   dbms_output.put_line (sqlst);
   execute immediate sqlst;
end test;will update every row that satisfies the criteria in a single statement. If there are 10 rows that start with '.THE ' then it will update 10 rows.

Use variables in a SELECT INTO FROM command

Hi,
How do I use variables within a select into from command? I want to loop through SYS.DBA_TABLES using a cursor and count the number of rows in a
selection of tables an then insert into a cardinality table.
The count of rows will be stored in a variable called CNT, that bit is easy however I need a variable in the FROM clause because that
value changes with every iteration of the cursor.
e.g.
CNT := 0;
TN := "MyTable";
select count(*) into CNT FROM TN;
insert into cardinality (table_name, row_count) values (TN, CNT);
This is Oracle 9i and I need the row counts in a separate table as they are shipped over to a different environment for analysis purposes.
Any ideas?
Regards
Dave
Edited by: Yorky001 on Sep 15, 2010 10:32 AM

Hi,
Thanks for the info, unfortunately I can get neither example to work on this 9i system, could well be pilot error as I only ever get
to do any Oracle about once per year. In the first query I have tried both "user_tables" and SYS.DBA_TABLES, same result.
set serveroutput on size 1000000;
DECLARE
row_count INTEGER;
vstr VARCHAR2(500);
vstr1 VARCHAR2(500);
BEGIN
vstr := 'SELECT count(*) FROM ';
dbms_output.put_line(vstr);
FOR i IN (SELECT table_name FROM user_tables WHERE rownum < 10) LOOP
vstr1 := vstr || i.table_name;
EXECUTE IMMEDIATE vstr1
INTO row_count;
dbms_output.put_line(i.table_name || ':' || row_count);
END LOOP;
END;
This one complains about the execute immediate line.
