I am getting an error indicating the wrong number of arguments when I run the following query:
SELECT
population_postcodes.*,
target_postcodes.*,
SQR( EXP(population_postcodes.longitude- target_postcodes.longitude, 2) + EXP(population_postcodes.latitude-target_postcodes.latitude, 2) ) as distance
FROM population_postcodes INNER JOIN target_postcodes on Population_postcodes.Population_postcode = Target_postcodes.Target_postcode;
Could anyone please suggest how I can fix this?
I have also tried the following code:
SELECT Population_postcodes.*, Target_postcodes.*
FROM population_postcodes
INNER JOIN target_postcodes
ON Population_postcodes.Population_postcode = Target_postcodes.Target_postcode
SQR( (population_postcodes.longitude- target_postcodes.longitude)^2 + (population_postcodes.latitude-target_postcodes.latitude)^2 ) as distance;
And this code:
SELECT Population_postcodes.*, Target_postcodes.*, SQR( (population_postcodes.longitude- target_postcodes.longitude)^2 + (population_postcodes.latitude-target_postcodes.latitude)^2 ) as distance
FROM population_postcodes
INNER JOIN target_postcodes
ON Population_postcodes.Population_postcode = Target_postcodes.Target_postcode;
Exp needs one parameter, you give two.
Old: EXP(population_postcodes.longitude- target_postcodes.longitude, 2)
New: (population_postcodes.longitude- target_postcodes.longitude)*(population_postcodes.longitude- target_postcodes.longitude)
Try replacing...
EXP(<expression>, 2)
...to...
<expression>^2
In Access, the EXP function returns e (the base of natural logarithms) raised to a power. To raise an expression to a power, use the ^ operator.
In your case, be careful to put brackets around the expression, for example...
(population_postcodes.longitude- target_postcodes.longitude)^2
...to force the power to be applied last. By default, the ^ operator is evaluated before the - operator.

I have the following select statement in ABAP:
SELECT munic~mandt VREFER BIS AB ZZELECDATE ZZCERTDATE CONSYEAR ZDIMO ZZONE_M ZZONE_T USAGE_M USAGE_T M2MC M2MT M2RET EXEMPTMCMT EXEMPRET CHARGEMCMT
INTO corresponding fields of table GT_INSTMUNIC_F
FROM ZCI00_INSTMUNIC AS MUNIC
INNER JOIN EVER AS EV on
MUNIC~POD = EV~VREFER(9).
"where EV~BSTATUS = '14' or EV~BSTATUS = '32'.
My problem with the above statement is that does not recognize the substring/offset operation on the 'ON' clause. If i remove the '(9) then
it recognizes the field, otherwise it gives error:
Field ev~refer is unknown. It is neither in one of the specified tables
nor defined by a "DATA" statement. I have also tried doing something similar in the 'Where' clause, receiving a similar error:
LOOP AT gt_instmunic.
clear wa_gt_instmunic_f.
wa_gt_instmunic_f-mandt = gt_instmunic-mandt.
wa_gt_instmunic_f-bis = gt_instmunic-bis.
wa_gt_instmunic_f-ab = gt_instmunic-ab.
wa_gt_instmunic_f-zzelecdate = gt_instmunic-zzelecdate.
wa_gt_instmunic_f-ZZCERTDATE = gt_instmunic-ZZCERTDATE.
wa_gt_instmunic_f-CONSYEAR = gt_instmunic-CONSYEAR.
wa_gt_instmunic_f-ZDIMO = gt_instmunic-ZDIMO.
wa_gt_instmunic_f-ZZONE_M = gt_instmunic-ZZONE_M.
wa_gt_instmunic_f-ZZONE_T = gt_instmunic-ZZONE_T.
wa_gt_instmunic_f-USAGE_M = gt_instmunic-USAGE_M.
wa_gt_instmunic_f-USAGE_T = gt_instmunic-USAGE_T.
temp_pod = gt_instmunic-pod.
SELECT vrefer
FROM ever
INTO wa_gt_instmunic_f-vrefer
WHERE ( vrefer(9) LIKE temp_pod ). " PROBLEM WITH SUBSTRING
"AND ( BSTATUS = '14' OR BSTATUS = '32' ).
ENDSELECT.
WRITE: / sy-dbcnt.
WRITE: / 'wa is: ', wa_gt_instmunic_f.
WRITE: / 'wa-ever is: ', wa_gt_instmunic_f-vrefer.
APPEND wa_gt_instmunic_f TO gt_instmunic_f.
WRITE: / wa_gt_instmunic_f-vrefer.
ENDLOOP.
itab_size = lines( gt_instmunic_f ).
WRITE: / 'Internal table populated with', itab_size, ' lines'.
The basic task i want to implement is to modify a specific field on one table,
pulling values from another. They have a common field ( pod = vrefer(9) ). Thanks in advance for your time.
If you are on a late enough NetWeaver version, it works on 7.51, you can use the OpenSQL function LEFT or SUBSTRING. Your query would look something like:
SELECT munic~mandt VREFER BIS AB ZZELECDATE ZZCERTDATE CONSYEAR ZDIMO ZZONE_M ZZONE_T USAGE_M USAGE_T M2MC M2MT M2RET EXEMPTMCMT EXEMPRET CHARGEMCMT
FROM ZCI00_INSTMUNIC AS MUNIC
INNER JOIN ever AS ev
ON MUNIC~POD EQ LEFT( EV~VREFER, 9 )
INTO corresponding fields of table GT_INSTMUNIC_F.
Note that the INTO clause needs to move to the end of the command as well.
field(9) is a subset operation that is processed by the ABAP environment and can not be translated into a database-level SQL statement (at least not at the moment, but I'd be surprised if it ever will be). Your best bet is either to select the datasets separately and merge them manually (if both are approximately equally large) or pre-select one and use a FAE/IN clause.
They have a common field ( pod = vrefer(9) )
This is a wrong assumption, because they both are not fields, but a field an other thing.
If you really need to do that task through SQL, I'll suggest you to check native SQL sentences like SUBSTRING and check if you can manage to use them within an EXEC_SQL or (better) the CL_SQL* classes.
SELECT p.pnum, p.pname
FROM professor p, class c
WHERE p.pnum = c.pnum AND c.cnum = CS245 AND (SELECT COUNT(*) FROM (SELECT MAX(m.grade), MAX(m.grade) - MIN(m.grade) AS diff
FROM mark m WHERE m.cnum = c.cnum AND m.term = c.term AND m.section = c.section AND diff <= 20)) = 3
Incorrect syntax near ')'. Expecting AS, FOR_PATH, ID, or QUOTED_ID.
Consider the following example:
SELECT COUNT(1)
FROM SYSCAT.TABLES T
WHERE
(
-- SELECT COUNT(1)
-- FROM
-- (
SELECT COUNT(1)
FROM SYSCAT.COLUMNS C
WHERE C.TABSCHEMA=T.TABSCHEMA AND C.TABNAME=T.TABNAME
-- )
) > 50;
The query above works as is. But the problem is, that if you uncomment the commented out lines, you get the following error message: "T.TABNAME" is an undefined name. and least in Db2 for Linux, Unix and Windows.
You can't push external to the sub-select column references too deeply.
So, your query is incorrect.
It's hard to correct it, until you provide the task description with data sample and the result expected.
I can see a potential syntax errors: It seems that CS245 refers to a value c.cnum may take and not a column name. If that is the case, it should be enclosed in single quotes.
I tried to retrieve a value from the calculation of several columns,
in this case try to apply the formula "(a + (a / 25 * b)) - c" to be processed using sql language which I will use in codeigniter.
I also tried using "derived table" like SELECT .... FROM (SELECT... FROM...) AS dt
but I had difficulty when applying it to my case in codeigniter
private function _get_datatables_query(){
$intvl = '2';
$tgl_stok = '2019-09-30';
$this->db->SELECT('p.hso, p.no_part, p.nama_part, jml, sp.oh, sum(p.qty)+(sum(p.qty)/25*$intvl)-sp.oh as suggest');
$this->db->FROM('penjualan p');
$this->db->JOIN('stok_part sp', 'sp.no_part = p.no_part', 'left');
$this->db->WHERE("sp.tgl = '$tgl_stok' AND p.tgl BETWEEN DATE_SUB('$tgl_stok', INTERVAL $intvl DAY) AND '$tgl_stok'");
$this->db->GROUP_BY('p.no_part');
//...other code...
}
I want a column with the alias suggest in the code to produce a calculated value of several other columns
I know writing code that I created is not in accordance with the rules of writing SQL, I tried a number of ways but it did not work. I am very grateful for your help
Instead of var you should use parameter in this way you can easly pass the value you need and avoid sqlinjection eg:
$sql = "SELECT p.hso, p.no_part, p.nama_part, jml, sp.oh, sum(p.qty)+(sum(p.qty)/25*?)-sp.oh as suggest
FROM enjualan p
LEFT JOIN stok_part sp ON sp.no_part = p.no_part
WHERE sp.tgl = ? AND p.tgl BETWEEN DATE_SUB(?, INTERVAL ? DAY) AND ?
GROUP BY p.no_part";
$this->db->query($sql, array($intval,$tgl_stok, $tgl_stok, $intvl, tgl_stok ));
}
I was solved this case.
the problem is in my query:
$this->db->SELECT('p.hso, p.no_part, p.nama_part, jml, sp.oh, sum(p.qty)+(sum(p.qty)/25*$intvl)-sp.oh as suggest');
and replace it with
$this->db->SELECT("p.hso, p.no_part, p.nama_part, sum(p.qty) as jml, sp.oh, sum(p.qty)+(sum(p.qty)/25*'$intvl')-sp.oh as s_po");
my mistake was writing quotation marks in the query

When I run the above query I am getting the beloiw error,

Any help please?
You have this in the where clause:
and (select * from [dbo].[CosmosData] where Variable = 'SURVEY_TYPE' and IntegerValue = '2')
SQL needs a boolean expression. This is usually formed by using = or a similar comparison operator. In your case, I think you just exant exists:
exists (select * from [dbo].[CosmosData] where Variable = 'SURVEY_TYPE' and IntegerValue = 2)
That said, you might want a correlation clause as well.
Note: I removed the single quotes from the integer value. Only use single quotes for string and date constants.
based on the assumption that you are using case as a key in this table, you can use the follwing to return all rows from cosmos data where your conditions are applied and the select in your where clause has a match using the criteria within it.

I'm trying to execute the following query in Oracle:
SELECT c.id_cliente, c.nombre_cliente, c.apellidos_cliente
FROM cliente c
WHERE not exists (SELECT f.id_finca
FROM finca f
WHERE f.habitaciones = 3
EXCEPT
SELECT v.id_fincas
FROM visitas v
WHERE v.id_cliente = c.id_cliente)
But I am getting the error "missing right parenthesis".
The parenthesis are well-balanced, how can I solve this error?
Use MINUS instead of EXCEPT.
SELECT c.id_cliente,
c.nombre_cliente,
c.apellidos_cliente
FROM cliente c
WHERE NOT EXISTS (SELECT f.id_finca
FROM finca f
WHERE f.habitaciones = 3
MINUS
SELECT v.id_fincas
FROM visitas v
WHERE v.id_cliente = c.id_cliente)
there is no operator EXCEPT in Oracle. Use MINUS instead of it.
Additionally, your query seems weird: better try to make it with two not exists, I think it can give some performance.
