But I can see this error only on run program.
Test query->grid activation works normal (with manually setup properties)
also if I do
AQ4->Close();
// AQ4->Parameters->Items[1]->Value=(int)TS->Tabs->Objects[NewTab];
AQ4->Open();
error :
AQ4: Field 'Visi' not found
AQ4 SQL :
FlowClientHardQ :ID_User, :ID_ListGroupParIzm
I also tough about DBGrid&Checkbox compability (Source) but as my field is normal bit I think that's not trouble, I made a mistake somewhere else...
Not sure about C++ builder, but in Delphi VCL, input parameters shall be marked with : and not with #.
First, put the query at design time in a query component and inspect the parameters property. If there's no parameters defined, try changing the # for :
Now, you are making more than one question here... so, let's go step by step.

Using Microsoft Visual FoxPro 9, I have a custom function, "newid()", inside of the stored procedures for Main:
function newId
parameter thisdbf
regional keynm, newkey, cOldSelect, lDone
keynm=padr(upper(thisdbf),50)
cOldSelect=alias()
lDone=.f.
do while not lDone
select keyvalue from main!idkeys where keyname=keynm into array akey
if _tally=0
insert into main!idkeys (keyname) value (keynm)
loop
endif
newkey=akey+1
update main!idkeys set keyvalue=newkey where keyname=keynm and keyvalue=akey
if _tally=1
lDone=.t.
endif
enddo
if not empty(cOldSelect)
select &cOldSelect
else
select 0
endif
return newkey
This function is used to generate a new ID for records added to the database.
It is called as the default value:
I would like to call this newid() function and retrieve its returned value. When executing SELECT newid("TABLENAME"), the error is is thrown:
Invalid subscript reference
How can I call the newid() function and return the newkey in Visual FoxPro 9?
As an addition to what Stefan Wuebbe said,
You actually had your answer in your previous question here that you forgot to update.
From your previous question, as I understand you are coming from a T-SQL background. While in T-SQL (and in SQL generally) there is:
Select < anyVariableOrFunction >
that returns a single column, single row result, in VFP 'select' like that has another meaning:
Select < aliasName >
aliasName is an alias of a working area (or it could be number of a work area) and is used to change the 'current workarea'. When it was used in xBase languages like FoxPro (and dBase), those languages didn't yet meet ANSI-SQL if I am not wrong. Anyway, in VFP there are two Select, this one and SELECT—SQL which definitely requires a FROM clause.
VFP has direct access to variables and function calls though, through the use of = operator.
SELECT newid("TABLENAME")
in T-SQL, would be (you are just displaying the result):
? newid("TABLENAME")
To store it in a variable, you would do something like:
local lnId
lnId = newid("TABLENAME")
* do something with m.lnId
* Note the m. prefix, it is a built-in alias for memory variables
After having said all these, as per your code.
It looks like it has been written by a very old FoxPro programmer and I must admit I am seeing it the first time in my life that someone used "REGIONAL" keyword in VFP. It is from FoxPro 2.x days I know but I didn't see anyone use it up until now :) Anyway, that code doesn't seem to be robust enough in a multiuser environment, you might want to change it. VFP ships with a NewId sample code and below is the slightly modified version that I have been using in many locations and proved to be reliable:
Function NewID
Lparameters tcAlias,tnCount
Local lcAlias, lnOldArea, lcOldReprocess, lcTable, lnTagNo, lnNewValue, lnLastValue, lcOldSetDeleted
lnOldArea = Select()
lnOldReprocess = Set('REPROCESS')
* Uppercase Alias name
lcAlias = Upper(Iif(Parameters() = 0, Alias(), tcAlias))
* Lock reprocess - try once
Set Reprocess To 1
If !Used("IDS")
Use ids In 0
Endif
* If no entry yet create
If !Seek(lcAlias, "Ids", "tablename")
Insert Into ids (tablename, NextID) Values (lcAlias,0)
Endif
* Lock, increment id, unlock, return nextid value
Do While !Rlock('ids')
* Delay before next lock trial
lnStart = Seconds()
Do While Seconds()-lnStart < 0.01
Enddo
Enddo
lnLastValue = ids.NextID
lnNewValue = m.lnLastValue + Evl(m.tnCount,1)
*Try to query primary key tag for lcAlias
lcTable = Iif( Used(lcAlias),Dbf(lcAlias), Iif(File(lcAlias+'.dbf'),lcAlias,''))
lcTable = Evl(m.lcTable,m.lcAlias)
If !Empty(lcTable)
Use (lcTable) In 0 Again Alias '_GetPKKey_'
For m.lnTagNo=1 To Tagcount('','_GetPKKey_')
If Primary(m.lnTagNo,'_GetPKKey_')
m.lcOldSetDeleted = Set("Deleted")
Set Deleted Off
Select '_GetPKKey_'
Set Order To Tag (Tag(m.lnTagNo,'_GetPKKey_')) ;
In '_GetPKKey_' Descending
Locate
lnLastValue = Max(m.lnLastValue, Evaluate(Key(m.lnTagNo,'_GetPKKey_')))
lnNewValue = m.lnLastValue + Evl(m.tnCount,1)
If Upper(m.lcOldSetDeleted) == 'ON'
Set Deleted On
Endif
Exit
Endif
Endfor
Use In '_GetPKKey_'
Select ids
Endif
* Increment
Replace ids.NextID With m.lnNewValue In 'ids'
Unlock In 'ids'
Select (lnOldArea)
Set Reprocess To lnOldReprocess
Return ids.NextID
Endfunc
Note: If you use this, as I see from your code, you would need to change the "id table" name to idkeys, field names to keyname, keyvalue:
ids => idKeys
tablename => keyName
nextId => keyValue
Or in your database just create a new table with this code:
CREATE TABLE ids (TableName c(50), NextId i)
INDEX on TableName TAG TableName
When executing SELECT newid("TABLENAME")
The error: Invalid subscript reference is thrown
The SQL Select command in Vfp requires a From clause.
Running a procedure or a function can, or better usually needs to be done differently:
For example, in the IDE's Command Window you can do a
? newid("xy") && the function must be "in scope",
&& i.e in your case the database that contains the "Stored
&& Procedure" must have been opened in advance
&& or you store the function result in a variable
Local lnNextID
lnNextID = newid("xy")
Or you can use it in an SQL SELECT when you have a From alias
CREATE CURSOR placebo (col1 Int)
INSERT INTO placebo VALUES (8)
Select newid("xy") FROM placebo
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.
I am working on a web app and there are some long winded stored procedures and just trying to figure something out, I have extracted this part of the stored proc, but cant get it to work. The guy who did this is creating alias after alias.. and I just want to get a section to work it out. Its complaining about the ending but all the curly brackets seem to match. Thanks in advance..

Well, I explained the issue in the comments section already. I'm doing it here again, so future readers find the answer more easily.
A WITH clause is part of a query. It creates a view on-the-fly, e.g.:
with toys as (select * from products where type = 'toys') select * from toys;
Without the query at the end, the statement is invalid (and would not make much sense anyhow; if one wanted a permanent view for later use, one would use CREATE VIEW instead).
First of all, I know there are already questions and answers about it, this thread being the one that is closest to what I need:
SQL Update to the SUM of its joined values
However, I get a syntax error (operator missing) that seems to occur close to the FROM clause. However I can't see it. Does it not like the FROM itself ? I am not used to using FROM in an update statement but it seems like it's valid from the QA I just linked :|
Any idea why there would be a syntax error there ?
I am using Access 2007 SP3.
Edit:
Wow, I forgot to post the query...
UPDATE r
SET
r.tempsmoy_requete_min = tmm.moy_mob_requete
FROM
rapports AS r INNER JOIN
(SELECT
id_fichier,
Round(Sum(temps_requete_min)/3,0) As moy_mob_requete,
Round(Sum(temps_analyse_min)/3,0) As moy_mob_analyse,
Round(Sum(temps_maj_min)/3,0) As moy_mob_maj,
Round(Sum(temps_rap_min)/3,0) As moy_mob_rap,
Round(Sum(temps_ddc_min)/3,0) As moy_mob_ddc
FROM maintenances
WHERE
periode In (10,9,8) And
annee=2011
GROUP BY id_fichier) AS tmm ON rapports.id_rapport = tmm.id_fichier
WHERE
1=0
The WHERE 1=0 part is because I want to test further the subquery before running it.
Edit: This is some simpler query I am trying. I get a different error this time. It now tells me that tempsmoy_requete_min (and probably all other left operands) are not part of an aggregate function... which is the point of my query. Any idea ?
UPDATE
rapports INNER JOIN maintenances ON rapports.id_rapport = maintenances.id_fichier
SET
rapports.tempsmoy_requete_min = Round(Sum(temps_requete_min)/3,0),
rapports.tempsmoy_analyse_min = Round(Sum(temps_analyse_min)/3,0),
rapports.tempsmoy_maj_min = Round(Sum(temps_maj_min)/3,0),
rapports.tempsmoy_rap_min = Round(Sum(temps_rap_min)/3,0),
rapports.tempsmoy_ddc_min = Round(Sum(temps_ddc_min)/3,0)
WHERE
maintenances.periode In (10,9,8) And
maintenances.annee=2011 AND
1=0
I tried adapting your first query sample, and was able to make your error go away. However then I encountered a different error ('Operation must use an updateable query').
It may be possible to overcome that error, too. However, I found it easier to use a domain function instead of a join to retrieve the replacement value.
UPDATE rapports
SET tempsmoy_requete_min = Round(DSum("temps_requete_min",
"maintenances",
"periode In (10,9,8) AND annee=2011 "
& "AND id_fichier='" & id_rapport
& "'")/3, 0);
If this suggestion works for tempsmoy_requete_min with your data, you will have to extend it to the other fields you want to replace. That won't be pretty. You could make it less ugly with a saved query which you then use as the "Domain" parameter for DSum() ... that could allow you to use a simpler "Criteria" parameter.
UPDATE r
should be
UPDATE rapports
You can't reliably use an alias in the update target.
I'm working on a IBM iseries v6r1m0 system.
I'm trying to execute a very simple query :
select * from XG.ART where DOS = 998 and (DES like 'ALB%' or DESABR like 'ALB%')
The columns are:
DOS -> numeric (3,0)
DES -> Graphic(80) CCSID 1200
DESABR -> Garphic(25) CCSID 1200
I get :
SQL State : 58004
SQL Code : -901
Message : [SQL0901] SQL System error.
Cause . . . . . : An SQL system error has occurred. The current SQL statement cannot be completed successfully. The error will not prevent other SQL statements from being processed. Previous messages may indicate that there is a problem with the SQL statement and SQL did not correctly diagnose the error. The previous message identifier was CPF4204. Internal error type 3107 has occurred. If precompiling, processing will not continue beyond this statement.
Recovery . . . : See the previous messages to determine if there is a problem with the SQL statement. To view the messages, use the DSPJOBLOG command if running interactively, or the WRKJOB command to view the output of a precompile.

If I change DES into REF (graphic(25)), it works...
EDIT :
I run some tests this afternoon, and it is very strange :
Just after the creation of the table/indexes, I have no errors.
If I insert some datas : error
If I clear the table : error
If I remove an index (see below) : it works (with or without datas)
!!
The index is :
create index XG.GTFAT_ART_B on XG.ART(
DOS,
DESABR,
ART_ID
)
Edit 2 :
Here is the job log (sorry, it is in French...)
It sais :

I finally contacted IBM.
It was an old bug from v5.
I have installed the latest PTF, and now, it works.
You need to use the GRAPHIC scalar function to convert your character literals on the LIKE predicate.
CREATE TABLE QTEMP/TEST (F1 GRAPHIC(80))
INSERT INTO QTEMP/TEST (F1) VALUES (GRAPHIC('TEST'))
SELECT * FROM QTEMP/TEST WHERE F1 LIKE GRAPHIC('TE%')
I know this guy got his problem fixed with an update. But here is something that worked for me that might work for the next guy here who has the problem.
My problem query had a lot of common table expressions. Most of them did not create tables with a whole lot of records. So if I figured that the maximum number of records a CTE would make was 1000, I added a "Fetch first 9999 rows only" to it. I knew that the CTE couldn't possibly have more rows than that. I guess the query optimizer had less to think about with that added.
If you have that problem and you don't have the option to upgrade or talk to IBM, I hope this help you.
For other people getting this errore, I encountered it on an IBM i Series v7r3, when tried an UPDATE, retrieving the value to be set on a field using a inner SELECT where multiple results where reduced to 1, using DISTINCT. I solved the problem removing DISTINCT and adding FETCH FIRST 1 ROW ONLY at the end of the inner SELECT.
E.g.: changed from
UPDATE MYTABLE AS T1
SET T1.FIELD1 = (
SELECT DISTINCT T2.FIELD5
FROM MYTABLE AS T2
WHERE T1.FIELD2 = T2.FIELD2
AND T1.FIELD3 = T2.FIELD3
)
WHERE T1.FIELD4 = 'XYZ'
to
UPDATE MYTABLE AS T1
SET T1.FIELD1 = (
SELECT T2.FIELD5
FROM MYTABLE AS T2
WHERE T1.FIELD2 = T2.FIELD2
AND T1.FIELD3 = T2.FIELD3
FETCH FIRST 1 ROW ONLY
)
WHERE T1.FIELD4 = 'XYZ'
