In the WHERE clause string variable

I have the procedure

CREATE OR REPLACE PROCEDURE proc1 (p_1 IN varchar2)
IS
BEGIN

DELETE FROM TABLE1
WHERE
Col1 = '@p_1. '
;

Dbms_output.put_line (number of rows sql %);

COMMIT;

EXCEPTION
WHILE OTHERS THEN
ROLLBACK;
RAISE_APPLICATION_ERROR (-20000, SQLERRM);
Proc1 END;
/

You will need to pass a string input parameter to the procedure. This string is applied to the WHERE clause. The foregoing does not work correctly the value of @p1 is in the WHERE clause. The value passed to the stored procedure does not run.

Please let me know the solution. I have to use BIND variables only.

Thank you

Thank you all. Yes, the underside of the works.

DELETE FROM TABLE1
WHERE
Col1 = p_1

PS: Both COL1 and p_1 are string values. Would like to know how it works with out the quotes because it is a string.

In addition I would like to follow the number of lines executed in each statement. Preference will have to use sql % rowcount. Are there other alternatives. Please let me know. Thanks in advance.

Oracle 'knows' that the variable p_1 is a varchar2 data type and that col1 is a varchar2 data type, so he makes a comparison between them strinf. This is how variables work in any programming language that I am aware. The only time that you must provide a value is when you use a literal value (for example in an assignment variable, or as a parameter of a procedure).

If you need to know the number of deleted rows, then sql % rowcount is the only sensible option. Just be aware that you need to get the value before committing yourself ot other options of SQL.

Please Help: query the value of the WHERE clause string

Hello world
I try the customers request that has corresponding name, but I get the result of every customer that has the name and surname. Here is my query:

SELECT * FROM  CUSTOMERS WHERE

Session variable in the WHERE clause of the SQL statement

Hey all,.
I was wonering just if there is a way to set the WHERE clause of the query that the session variable? I have the following so far and have tried to go through a ton of tutorials, but it doesn't seem to work. Is it still possible? I don't know what follows is wrong, but can someone help me with changing the following code, or pointing me to a good tutorial? (I write it with PHP)
$query = "SELECT * from members where user_id = ' $_SESSION ['members']";
Thanks for your help.

$member = "-1";
If (isset($_SESSION['members'])) {}

DECODE inside the WHERE clause

Hi all:

I can't get the DECODE statement to work inside my WHERE clause. I have read the information on
Tahiti.Oracle.com
http://download.Oracle.com/docs/CD/E11882_01/server.112/e17118/functions049.htm#i1017437

But still can not get it to work. Initially, I had he works as dynamic SQL and then run that string, but I am not allowed to use dynamic SQL statements and to do 'Real' PL/SQL.

I have the following WHERE clause (more info after the WHERE clause)

WHERE 
     a.ebiz_asn_no(+) = te.ebiz_cntrl_no
     AND w.ebiz_work_no(+) = te.ebiz_cntrl_no
     AND o.ebiz_ord_no(+) = ebiz_cntrl_no
     AND t.ebiz_trailer_no(+) = te.ebiz_trailer_no
     AND ms.ebiz_sku_no(+) = te.ebiz_sku_no 
     AND NVL(ms.ebiz_sku_no, -1) = NVL(p_SKU, nvl(ms.ebiz_sku_no, -1))

     AND te.comp_id = p_CompID

     AND INSTR('' || p_TaskType || '', te.task_type) > 0 
     AND NVL(task_priority, -1) = NVL(p_Priority, NVL(task_priority, -1)) 
     AND NVL(te.ebiz_cntrl_no, -1) = DECODE(te.task_type, 'IULD', DECODE(p_Order, null, te.ebiz_cntrl_no, ebiz_po2asn.get_ebiz_po_no(p_Order)), NVL(p_Order, NVL

     || whereClauseStatus 
     || whereClauseFromDate 
     || whereClauseToDate;

As you can see, initially I was adding values of "whereClauseStatus, whereClauseFromDate, whereClauseToDate" and it has been defined with the following PL/SQL code:

     IF(p_TaskStatus = 'C') THEN
          -------------------------------------------------------------------------------------------
          --     Set From Date Clause
          -------------------------------------------------------------------------------------------
          IF(p_FromShipDate IS NOT NULL) THEN
               whereClauseFromDate := ' AND TRUNC(te.act_end_date) >= TO_DATE(''' || p_FromShipDate || ''',''MM/dd/yyyy'') ';
          END IF;
          -------------------------------------------------------------------------------------------
          --     Set To Date Clause
          -------------------------------------------------------------------------------------------
          IF (p_ToShipDate IS NOT NULL) THEN
               whereClauseToDate := ' AND TRUNC(te.act_end_date) <= TO_DATE(''' || p_ToShipDate || ''',''MM/dd/yyyy'') ';
          END IF;
     ELSE

          END IF;

          -------------------------------------------------------------------------------------------
          IF (p_ToShipDate IS NOT NULL) THEN
               whereClauseToDate := ' AND TRUNC(te.currdate) <= TO_DATE(''' || p_ToShipDate || ''',''MM/dd/yyyy'') ';
          END IF;
     END IF;
     

     IF (p_TaskStatus = 'I') THEN
          whereClauseStatus := ' AND act_end_date IS NULL ';
     ELSIF (p_TaskStatus = 'C') THEN
          whereClauseStatus := ' AND act_end_date IS NOT NULL ';
     ELSE
          whereClauseStatus := '';
     END IF;

I have serious problems getting the DECODE statement to replace the three variables in the annex.

Any help would be greatly appreciated.

Thank you

spleen the last clause. Oops.

Beginner: Get on the WHERE clause syntax error in SELECT

I am very new to php and mySQL. Use DW master/detail to generate Basic code I need. One thing I have to do is to modify a select statement in the master to include a WHERE clause to limit the selection to a particular value in a field.
I get a syntax error with the select statement in the WHERE clause, I add to the map.
It's the part of the error message showing the location of the error:
"WHERE group = 'Community' LIMIT 0, 10'"
Php that generated the select is:
$query_maps = "SELECT * FROM tblmaps ORDER BY tblmaps.» DispSeq ';
$query_limit_maps = sprintf ("%s WHERE group =' LIMIT %s %d, %d", $query_maps, $selectGroup, $startRow_maps, $maxRows_maps);
This approach to create the select statement is on the generated code for the master page. He added the LIMIT clause. I didn't add the ' WHERE group = '%s' and the variable $selectGroup, which comes from the old code.» You can see that the $selectGroup variable is equal to the "community: group.»
I scanned the web to see what syntax error, I could do, but haven't found anything that explains it.
The resolved full select statement is:
SELECT * FROM tblmaps ORDER BY tblmaps. WHERE DispSeq = 'Community' LIMIT 0,10 group
What I don't see?
Tom

The group is a reserved word in MySQL. You could probably put single quotes around it, but I suggest to rename this column. Do not use reserved words for column names.

DECODE does not work in the WHERE clause when subquery returns more than one line
Hi gurus,

I want to write a query against the table CCENTERS (Script given below) and wait for the following result:

1. in the transition from a value of 0 for the ID, it returns all the rows in the table.
2. in the passage of one value other than 0, it returns the row corresponding to the given value and all its records of the child.

CCENTER has parent-child relationship in the column ID and the BASE. I use a query with the DECODE function. but the function in the WHERE clause is not capable of managing the subquery with multiple lines of DECODE.

*************************************************
VARIABLE ParaCCenter NUMBER

BEGIN
: paraccenter: = 0;
END;
/

CREATE TABLE ccenters
(id NUMBER,
name VARCHAR2 (20).
number base);

INSERT INTO ccenters VALUES(1,'NUST',null);
INSERT INTO ccenters VALUES(2,'SEECS',1);
INSERT INTO ccenters VALUES(3,'NBS',1);
commit;

SELECT * from ccenters
WHERE id IN DECODE(:ParaCCenter, 0, id,)
(SELECT id FROM ccenters
START WITH basic =: ParaCCenter
ID of CONNECTION BY PRIOR = base
UNION
SELECT: ParaCCenter OF double
)
)
/
BEGIN
: paraCCenter: = 1;
END;
/

SELECT * from ccenters
WHERE id IN DECODE(:ParaCCenter, 0, id,)
(SELECT id FROM ccenters
START WITH basic =: ParaCCenter
ID of CONNECTION BY PRIOR = base
UNION
SELECT: ParaCCenter double))
/
The result is
(SELECT id FROM ccenters
*
ERROR at line 3:
ORA-01427: einreihig subquery returns multiple rows

How this query can be rewritten for the given feature. Any response will be appreciated.

Thank you
Try something like this:
```
SELECT * FROM ccenters
WHERE :ParaCCenter = 0
OR id in
  (SELECT id FROM ccenters
   START WITH base=:ParaCCenter
   CONNECT BY PRIOR id = base
   UNION
   SELECT :ParaCCenter FROM dual
  )

Execution of statement of UPDATE for the whole table even when the WHERE Clause is presentation
Hi friends,

I have a problem in a stored procedure where I wrote an update with a where clause clause statement. At some point only one line should be updated according to the unique identifier in where clause.

But what is happening is that the Update statement is getting executed for all rows in the table to neglect the WHERE clause. I don't get any idea of why this is happening. Here is the stored procedure and the update statement is BOLD:-

This will always be value true - similar to WHERE 1 = 1.

You typed it wrong or is the same as the variable column name? If they are the same test rename one of them.

Try adding conditions to clause "and" stored in the table for the where clause, unknown syntax

I am trying to add additional segments to the 'where' clause, and I don't know exactly how to proceed. I am currently using another table to search for keywords and sometimes there aren't everything. I use this table containing the key words to search the description and associate a symbol with a path.
The code loops through the keywords with the keywords most associated and try to find links to a symbol then excludes those and search for symbols that correspond to those with less keywords and all. I am able to do this with 6 queries and manually changing the arguments, but I want to loop together so that if the changes need to be made in the future, I won't need to go digging in the code.

Thanks, but that's ok. I already have a solution for this.

Outer joins and null in the 'where' clause condition

Hi people,
Please help me on this.
Here's my query.
with x
(select 'a' as a dual union all col1)
Select 'b' as col1 of union double all the
Select 'c' as double col1
),
y as
(
Select 'b' as col2 from dual Union all the
Select 'c' as col2 from dual Union all the
Select would be "as col2 from dual Union all the"
Select 'e' as col2 from dual
)
Select * x y right outer join
on x.col1 = y.col2 and y.col2 is null
Get all the lines of 'COL1' as null. Why like this?

Just add the condition to the WHERE clause for example
```
WITH x AS
(SELECT 'a' AS col1 FROM dual UNION ALL
SELECT 'b' AS col1 FROM dual UNION ALL
SELECT 'c' AS col1 FROM dual
),
y AS
(
SELECT 'b' AS col2 FROM dual UNION ALL
SELECT 'c' AS col2 FROM dual UNION ALL
SELECT 'd' AS col2 FROM dual UNION ALL
SELECT 'e' AS col2 FROM dual
)
SELECT * FROM x LEFT OUTER JOIN y
ON x.col1=y.col2                     ----want to add "and y.col2 is null " condition to get value "a"
where y.col2 is null

T/t with the WHERE clause using a list breaks

Hello, all,.
I have a project where I need to use a list as part of the WHERE clause for a t/t, and it is breaking. I don't know what I'm doing wrong.
For some pseudo-code, do I have a complete query of a database called 'people '. A list of values for the t/t with the first query; the second query is my t/t:
```
<cfquery name="getDIR" datasource="#request.THISDSN#">
    SELECT thisName dir FROM orgs WHERE thisID in (<cfqueryparam value="#form.org#" cfsqltype="cf_sql_varchar" list="yes" />)
</cfquery>

<cfquery name="people" database="people">
    SELECT colA, colB, colC, colD
    FROM people
    WHERE 1=1
        AND (
            div IN (<cfqueryparam value="#valueList(getDIR.dir)#" cfsqltype="varchar" list="yes" />)
            OR dir IN (<cfqueryparam value="#valueList(getDIR.dir)#" cfsqltype="varchar" list="yes" />)
            )
</cfquery>
```
I get the error message is "t/t syntax error: encountered" div IN \'thisValue\' ".» Incorrect conditional expression, waiting for one of [as | null | between | in | comparison] condition. »
Can support _not_ QoQ lists of WHERE clauses?
V/r,

SMH - so much... I just found.

I forgot to give the lists in the second query bracket.

(The pseudocode was manually typed, since my dev system is isolated from the internet, and I added the in my pseudo code when they were not in my original code.)

And even if I write the LOOP before the first CASE, it returns me the current value and move to the last record.
Please suggest

Try something like this:
```
FIRST_RECORD;

LOOP

  IF :contact.cb = 'Y' THEN
    IF p_where is null then
       p_where := :contact.code;
     else
       p_where := p_where ||','||:contact.code;
     end if;
   END IF;
  exit when :system.last_record = 'TRUE';
  next_record;
END LOOP;

-- END LOOP;
MESSAGE ( 'p_where :'||p_where);
MESSAGE (' ');

END;
```

Tuning - using the CASE statement in the WHERE clause of the query

Hi all

My request has been changed to use a CASE statement in the WHERE clause to examine the data to some columns based on a parameter value. This modified request is made a full table and constantly running scan. Please suggest what can be done to improve its performance:

Query:

SELECT LAST_DAY(TRUNC(TO_TIMESTAMP(os.requestdatetime, 'yyyymmddhh24:mi:ss.ff4'))) AS summary_date,
os.acctnum,
os.avieworigin_refid,
COUNT(1) cnt_articleview,
SUM(NVL(autocompletedterm,0)) cnt_autocompletedterm
FROM TABLE1 os
WHERE os.acctnum IS NOT NULL
AND os.avieworigin_refid IS NOT NULL
AND os.requestdatetime IS NOT NULL
AND UPPER(os.success_ind) = 'S'

AND CASE WHEN
Param_ValueToCheck  = 'FULL' AND get_date_timestamp(os.requestdatetime)  BETWEEN 
TO_DATE('01-MAY-2011 00:00:00','DD-MON-YYYY HH24:MI:SS') AND
TO_DATE('31-MAY-2011 00:00:00','DD-MON-YYYY HH24:MI:SS')
THEN 1
WHEN
Param_ValueToCheck  = 'INCR' AND os.entry_createddate  BETWEEN 
TO_DATE('01-MAY-2011 00:00:00','DD-MON-YYYY HH24:MI:SS') AND
TO_DATE('31-MAY-2011 00:00:00','DD-MON-YYYY HH24:MI:SS')
THEN 1
END = 1
AND CASE WHEN
Param_ValueToCheck  = 'FULL' AND os.entry_CreatedDate BETWEEN 
TO_DATE('01-APR-2011 00:00:00','DD-MON-YYYY HH24:MI:SS') AND
TO_DATE('07-JUN-2011 00:00:00','DD-MON-YYYY HH24:MI:SS')
THEN 1
WHEN
Param_ValueToCheck  = 'INCR' THEN 1
END = 1
GROUP BY LAST_DAY(TRUNC(TO_TIMESTAMP(os.requestdatetime, 'yyyymmddhh24:mi:ss.ff4'))), os.acctnum,os.avieworigin_refid;

When it is executed individually, MERGE LOGIC 1 and LOGIC of MERGE 2 take about ten for a daterange of 30 days data.

BUT FULL is to get the scores of APR - JUN, INCR becomes partitions for MAY so not both 30 days.

Trouble using a function in the where clause
Hello

I use a function that is located at ask.tom.oracle.com, which converts a long data type in a character. The function returns an error when it is placed in the where clause. The sql statement, the error message and the function of asking tom are listed below. Does anyone know how to fix this?

Setting in the WHERE clause of the query
Hi all

I have 2 tables.

TABLE_A contains 10 million documents.
TABLE_B contains 100 records.

I associate myself with these 2 tables

Here's a.ID left
```
SELECT A.*, B.*
FROM TABLE_A a, TABLE_B b
WHERE a.ID = b.ID;
```
Here's b.ID left
```
SELECT A.*, B.*
FROM TABLE_A a, TABLE_B b
WHERE b.ID = a.ID;
```
My question is what query will give better performance? I thought that, if we put the column in the table with a lower number of lines on the left, then it will be faster than the other.
In current versions of Oracle, it does not matter in what order you sum-up your predicates in the WHERE clause of a query: they will be optimized/executed in a way even.

Problems of execution of a SQL function with a variable in the WHERE clause

Hello world!
I have programmed a function that returns a boolean value based on the result of the SQL. It's the function:
FUNCTION existe_secuencial (seq_name VARCHAR2) RETURN AS BOOLEAN
cursor c2 is SELECT FROM all_sequences WHERE upper (sequence_name) = sequence_name' | seq_name | ' ;
BEGIN
OPEN c2;
DBMS_OUTPUT. Put_line (nombre_seq);
Get c2 INTO kk;
If c2% NOTFOUND = True THEN
RETURNS false;
on the other
RETURNS true;
end if;
END existe_secuencial;
And I give the floor to the function of a procedure in this way:
IF existe_secuencial ("SEQ_ARQUETA") = True THEN
DBMS_OUTPUT. Put_line ('exists');
ON THE OTHER
DBMS_OUTPUT. Put_line ("' NOT exists");
END IF;
The probrem that this SQL is forced to return results because this sequence exists in the comic book, but is not, return me the FALSE value. What makes me mad is that if I change the second line of the function in this way:
> > cursor c2 is SELECT FROM all_sequences WHERE upper (sequence_name) sequence_name ="SEQ_ARQUETA";
It works find and return of sequence existing (real)
Can someone help me please, I'm quite desperate to find what is the problem with that because I do not understand why if I built the slider with a variable returns no results so that if I do write it works...
Thanks in advance!
Itziar

Frame you your variable in quotes, which makes the string literal ' |. ' seq_name | "rather than the content of the variable.

I think that something like this would be an improvement.

function existe_secuencial (seq_name VARCHAR2) return a Boolean value as

number of exist_check: = 0;

Start

Start

Select 1

in exist_check

of all_sequences

where upper (sequence_name) = upper (seq_name);

exception

When no_data_found then

null;

end;

return (exist_check = 1);

end existe_secuencial;

In the WHERE clause string variable
