I've a query like this:
SELECT personas.IDDNI iddni,
PERSONAS.NOMBRE NOMBRE,
PERSONAS.APELLIDO1 APELLIDO1,
PERSONAS.APELLIDO2 APELLIDO2,
PERSONAS.ANTIGUEDAD ANTIGUEDAD,
VACACIONES(personas.IDDNI, to_char(add_months(sysdate, 0), 'YYYY')) VACACIONES
FROM personas personas,
trieniosobservaciones t
WHERE personas.iddni = t.iddni
AND ( personas.iddni = '47656567' )
I'd like to know what VACACIONES(personas.IDDNI,to_char(add_months(sysdate,0),'YYYY')) VACACIONES does in the query, as depending on the personas.iddni value it can return one row or give the following error:
The number specified in exact fetch is less than the rows returned.
VACACIONES is a user-defined function that takes two arguments, an IDDNI value for a person and a year. Beyond that, we cannot tell you what it does because it is a user-defined function and we do not have access to your database or the source code of the function.
You can find the source-code of the function using:
SELECT *
FROM all_source
WHERE name = 'VACACIONES'
AND type = 'FUNCTION'
ORDER BY owner, line;
and then you can work out what it does.

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:

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.
I need to update an XML node that contains a specific number. My query works if I hard code in the number (see figure 1), but I would like to make this dynamic by passing through a variable that contains a string (variableToBeReplaced). I currently wrote this (see figure 2) but it isn't reading the variable correctly so no changes are being made to the xml. Does anyone know how I can include a variable in an updatexml() function?
Figure 1
select updateXML(xmltype(xmlbod),'/LpnList/Lpn/LicensePlateNumber[text() = "12345"]','67890').getClobVal() doc
from myTable
where id = '1'
Figure 2
select updateXML(xmltype(xmlbod), '/LpnList/Lpn/LicensePlateNumber[text()= '|| variableToBeReplaced || ']','67890').getClobVal() doc
from myTable
where id = '1'
I was just missing "" around the variable.
select updateXML(xmltype(xmlbod), '/LpnList/Lpn/LicensePlateNumber[text()= "'|| variableToBeReplaced || '"]','67890').getClobVal() doc
from myTable
where id = '1'
I have the following function:
CREATE OR REPLACE FUNCTION calc_a(BIDoctor number) RETURN number
IS
num_a number;
BEGIN
select count(NAppoint)
into num_a
from Appointment a
where BIDoctor = a.BIDoctor;
RETURN num_a;
END calc_a;
What we want is adding a column to a report that shows us the number of appointments that doc have.
select a.BIdoctor "NUM_ALUNO",
a.NameP "Nome",
a.Address "Local",
a.Salary "salary",
a.Phone "phone",
a.NumberService "Curso",
c.BIdoctor "bi",
calc_media(a.BIdoctor) "consultas"
FROM "#OWNER#"."v_Doctor" a, "#OWNER#"."Appointment" c
WHERE a.BIdoctor = c.BIdoctor;
and we got this when we are writing the region source on apex.
But it shows a parse error, I was looking for this about 2 hours and nothing.
Apex shows me this:
PARSE ERROR ON THE FOLLOWING QUERY
This is probably because of all your double quotes, you seem to have randomly cased everything. Double quotes indicate that you're using quoted identifiers, i.e. the object/column must be created with that exact name - "Hi" is not the same as "hi". Judging by your function get rid of all the double quotes - you don't seem to need them.
More generally don't use quoted identifiers. Ever. They cause far more trouble then they're worth. You'll know when you want to use them in the future, if it ever becomes necessary.
There are a few more problems with your SELECT statement.
You're using implicit joins. Explicit joins were added in SQL-92; it's time to start using them - for your future career where you might interact with other RDBMS if nothing else.
There's absolutely no need for your function; you can use the analytic function, COUNT() instead.
Your aliases are a bit wonky - why does a refer to doctors and c to appointments?
Putting all of this together you get:
select d.bidoctor as num_aluno
, d.namep as nome
, d.address as local
, d.salary as salary
, d.phone as phone
, d.numberservice as curso
, a.bidoctor as bi
, count(nappoint) over (partition by a.bidoctor) as consultas
from #owner#.v_doctor a
join #owner#.appointment c
on d.bidoctor = a.bidoctor;
I'm guessing at what the primary keys of APPOINTMENT and V_DOCTOR are but I'm hoping they're NAPPOINT and BIDOCTOR respectively.
Incidentally, your function will never have returned the correct result because you haven't limited the scope of the parameter in your query; you would have just counted the number of records in APPOINTMENT. When you're naming parameters the same as columns in a table you have to explicitly limit the scope to the parameter in any queries you write, for instance:
select count(nappoint) into num_a
from appointment a
where calc_a.bidoctor = a.bidoctor; -- HERE
I have the following query.
$query = $this->db->query('SELECT COUNT(*) FROM iplog.persons WHERE begin_date LIKE '2014%'');
I need to count the number of columns with a begin_date in the year 2014.
When I run this script I'm getting an error:
Parse error: syntax error, unexpected '2014' (T_LNUMBER) in C:\xampp\htdocs\iPlog2\application\controllers\stat.php on line 12
I was trying to change my CI script to
$query = $this->db->query('SELECT COUNT(*) FROM iplog.persons WHERE begin_date LIKE "2014%"');
but it caused an error.
You mean, count ROWS:
So for that, just count the number of rows you have based on a condition:
$year = '2014'
$this->db->from('iplog');
$this->db->like('begin_date', $year);
$query = $this->db->get();
$rowcount = $query->num_rows();
First, you have a simple typo regarding the use of single quotes. Your complete sql string should be double quoted so that your value-quoting can be single quoted.
Second, you are using inappropriate query logic. When you want to make a comparison on a DATE or DATETIME type column, you should NEVER be using LIKE. There are specific MYSQL functions dedicated to handling these types. In your case, you should be using YEAR() to isolate the year component of your begin_date values.
Resource: https://www.w3resource.com/mysql/date-and-time-functions/mysql-year-function.php
You could write the raw query like this: (COUNT(*) and COUNT(1) are equivalent)
$count = $this->db
->query("SELECT COUNT(1) FROM persons WHERE YEAR(begin_date) = 2014")
->row()
->COUNT;
Or if you want to employ Codeigniter methods to build the query:
$count = $this->db
->where("YEAR(begin_date) = 2014")
->count_all_results("persons");
You could return all of the values in all of the rows that qualify, but that would mean asking the database for values that you have no intention of using -- this is not best practice. I do not recommend the following:
$count = $this->db
->get_where('persons', 'YEAR(begin_date) = 2014')
->num_rows();
For this reason, you should not be generating a fully populated result set then calling num_rows() or count() when you have no intention of using the values in the result set.
Replace quotes like this :
$query = $this->db->query("SELECT COUNT(*) FROM iplog.persons WHERE begin_date LIKE '2014%'");
Double quote your entire query, then simple quote your LIKE criteria.
i'm having an issue comparing a date in an access database. basically i'm parsing out a date from a text field, then trying to compare that date to another to only pull newer/older records.
so far i have everything working, but when i try to add the expression to the where clause, it's acting like it's not a date value.
here's the full SQL:

the value i'm trying to compare against a various date is this:
DateValue(Trim(Left([bc_TestingTickets].[notes],InStr([bc_TestingTickets].[notes],' '))))
if i add a section to the where clause like below, i get the Data Type Mismatch error:
WHERE DateValue(Trim(Left([bc_TestingTickets].[notes],InStr([bc_TestingTickets].[notes],' ')))) > #4/1/2012#
i've even tried using the DateValue function around the manual date i'm testing with but i still get the mismatch error:
WHERE DateValue(Trim(Left([bc_TestingTickets].[notes],InStr([bc_TestingTickets].[notes],' ')))) > DateValue("4/1/2012")
any tips on how i can compare a date in this method? i can't change any fields in the database, ect, that's why i'm parsing the date in SQL and trying to manipulate it so i can run reports against it.
i've tried googling but nothing specifically talks about parsing a date from text and converting it to a date object. i think it may be a bug or the way the date is being returned from the left/trim functions. you can see i've added a column to the end of the SELECT statement called DateTest and it's obvious access is treating it like a date (when the query is run, it asks to sort by oldest to newest/newest to oldest instead of A-Z or Z-A), unlike the second column in the select.
thanks in advance for any tips/clues on how i can query based on the date.
edit:
i just tried the following statements in my where clause and still getting a mismatch:
CDate(Trim(Left([bc_TestingTickets].[notes],InStr([bc_TestingTickets].[notes],' ')))) > #4/1/2012#
CDate(Trim(Left([bc_TestingTickets].[notes],InStr([bc_TestingTickets].[notes],' ')))) >
CDate("4/1/2012") CDate(DateValue(Trim(Left([bc_TestingTickets].[notes],InStr([bc_TestingTickets].[notes],' '))))) > #4/1/2012#
i tried with all the various combinations i could think of regarding putting CDate inside of DateValue, outside, ect. the CDate function does look like what i should be using though. not sure why it's still throwing the error.
here's a link to a screenshot showing the results of the query http://ramonecung.com/access.jpg. there's two screenshots in one image.
You reported you get Data Type Mismatch error with this WHERE clause.
WHERE DateValue(Trim(Left([bc_TestingTickets].[notes],
InStr([bc_TestingTickets].[notes],' ')))) > #4/1/2012#
That makes me wonder whether [bc_TestingTickets].[notes] can ever be Null, either because the table design allows Null for that field, or Nulls are prohibited by the design but are present in the query's set of candidate rows as the result of a LEFT or RIGHT JOIN.
If Nulls are present, your situation may be similar to this simple query which also triggers the data type mismatch error:
SELECT DateValue(Trim(Left(Null,InStr(Null,' '))));
If that proves to be the cause of your problem, you will have to design around it somehow. I can't offer a suggestion about how you should do that. Trying to analyze your query scared me away. :-(
It seems like you are having a problem with the type conversion. In this case, I believe that you are looking for the CDate function.
A problem might be the order of the date parts. A test in the Immediate window shows this
?cdate(#4/1/2012#)
01.04.2012
?cdate(#2012/1/4#)
04.01.2012
Write the dates backwards in the format yyyy/MM/dd and thus avoiding inadverted swapping of days and months!
DateValue("2012/1/4")
and
CDate(#2012/1/4#)
