Overflow error for MS Access 2000 Query

Posted on 2004-09-07
Last Modified: 2012-05-05
Hi Experts,

I have the following query in Access 2000 and gets 'overflow' error when I tried to run it.
My query was working fine untill I added->WHERE ((([ACTEXP]+[COMEXP])/[BUDAMT])>0.8)
I only want select the record if its ([ACTEXP]+[COMEXP])/[BUDAMT] >80%

Thanks in advance!

SELECT [Acctstat].[FUNDAC], [Fundacs].[DESC] AS Fundacs_DESC, [Acctstat].[OBJ], [Objcodes].[DESC] AS Objcodes_DESC, [Acctstat].[BUDAMT], Sum(IIf([req query for acctstat calculations]![OBJ]=[Acctstat]![OBJ] And [req query for acctstat calculations]![FUNDAC]=[Acctstat]![FUNDAC],[req query for acctstat calculations]![EXPAMT],0)) AS ACTEXP, Sum(IIf([req query for acctstat calculations]![OBJ]=[Acctstat]![OBJ] And [req query for acctstat calculations]![FUNDAC]=[Acctstat]![FUNDAC],[req query for acctstat calculations]![REQBAL],0)) AS COMEXP, [BUDAMT]-[ACTEXP] AS ACTBAL, ([BUDAMT]-[ACTEXP])-[COMEXP] AS AVAILBAL, IIf([BUDAMT]<>0,100*[ACTEXP]/[BUDAMT],0) AS PERACT, IIf([BUDAMT]<>0,(IIf([BUDAMT]=0 And [COMEXP]=0,1,100*([ACTEXP]+[COMEXP])/[BUDAMT])),0) AS PERAVAIL
FROM [req query for acctstat calculations], (Acctstat INNER JOIN Objcodes ON [Acctstat].[OBJ]=[Objcodes].[OBJ]) INNER JOIN Fundacs ON [Acctstat].[FUNDAC]=[Fundacs].[FUNDAC]
GROUP BY [Acctstat].[FUNDAC], [Fundacs].[DESC], [Acctstat].[OBJ], [Objcodes].[DESC], [Acctstat].[BUDAMT], [BUDAMT]-[ACTEXP], ([BUDAMT]-[ACTEXP])-[COMEXP], IIf([BUDAMT]<>0,100*[ACTEXP]/[BUDAMT],0), IIf([BUDAMT]<>0,(IIf([BUDAMT]=0 And [COMEXP]=0,1,100*([ACTEXP]+[COMEXP])/[BUDAMT])),0), [req query for acctstat calculations].[FUNDAC]
HAVING ((([req query for acctstat calculations].FUNDAC)=[Acctstat]![FUNDAC]))
ORDER BY [Acctstat].[FUNDAC], [Acctstat].[OBJ];

Check the field definitions on all these fields.  An Overflow error is where you try to populate a field with a certain field type with a number that is beyond what it's capable of.

For example, Integer can handle -32767 to +32768, so if you try to feed it 200,000, you get an overflow error.
Byte can handle 0 to 255, so if you try to feed it 500 or -5, you get an overflow error.

You get the idea.

Hope this helps.

is [BUDAMT] value a zero in the data you are using?

[BUDAMT] has a zero value sometimes and I think that caused the error, but how to fix it?

What do you want to do if [BUDAMT] has a zero value?

try to modify this example:

WHERE ([BUDAMT] <>0 and (([ACTEXP]+[COMEXP])/[BUDAMT])>0.8)

Both [ACTEXP] and [COMEXP] can be either Null or zero. They are just calculation from other fields.

WHERE ([ACTEXP]>0 and [COMEXP]>0 and [BUDAMT] >0 and (([ACTEXP]+[COMEXP])/[BUDAMT])>0.8)

OR try the  other way around

WHERE (IsNull([ACTEXP]) = False And IsNull([COMEXP]) = False And IsNull([BUDAMT]) = False And [ACTEXP] <> 0 And [COMEXP] <> 0 And [BUDAMT] <> 0 And (([ACTEXP] + [COMEXP]) / [BUDAMT]) > 0.8)

Actually I want use-> WHERE (Sum([ACTEXP])>0 And Sum([COMEXP])>0 And Sum([BUDAMT])>0 And ((Sum([ACTEXP])+Sum([COMEXP]))/Sum([BUDAMT]))>0.8)

Got error: can't have aggregate function in where clause.

Hi mrong

Don't put the Sum in the Where statement,
make another field in the query, call it SumACTEXP, like this:
SumACTEXP: dsum("[ACTEXP]","TableName", where condition if any)
SumCOMEXP: dsum("[COMEXP]","TableName", where condition if any)
SumBUDAMT: dsum("[BUDAMT]","TableName", where condition if any)

then your Where statement should look like this:

WHERE ([SumACTEXP]>0 and [SumCOMEXP]>0 and [SumBUDAMT] >0 and (([ACTEXP]+[COMEXP])/[BUDAMT])>0.8)

Alternatively, you can put the DSUM statements in the Form where you are calling the Query from and refere to it like this:

WHERE (Forms![FormName]![SumACTEXP]>0 and Forms![FormName]![SumCOMEXP]>0 and Forms![FormName]![SumBUDAMT] >0 and (([ACTEXP]+[COMEXP])/[BUDAMT])>0.8)
