Union Query SQL

croy

This Union query has me stumped. The SQL for each of the
two querys runs fine on their own, but together in this
union the query runs, shows the first screen of data, and
then dumps "Data mismatch" in a dialog. I'm beginning to
suspect that the problem may not be data mismatch, but I
can't figure out what it is.

Here's the SQL (badly wrapped):

SELECT
IIf([GeoLocDE]="10.1","10.1",IIf([GeoLocDE]="11","11",IIf([GeoLocDE]="11.1","11",IIf([GeoLocDE]="11.2","11",IIf([GeoLocDE]="12.1","12.1",Int([GeoLocDE]))))))
AS Loc, tblIvSurv.SurveyDate, tblIvDetail.RiverMile,
tblMethod.MethDE, tblIvDetail.NumberAnglers,
tblIvDetail.HrsFished, tblIvDetail.SpeciesId AS Target,
tblIvDetail.Done, tblIvDetail.ZipCode,
IIf([SpeciesDE]="SHCL","SH",IIf([SpeciesDE]="SHU","SH",IIf([SpeciesDE]="RTCL","RT",IIf([SpeciesDE]="RTU","RT",IIf(IsNull([SpeciesDE]),"--",[SpeciesDE])))))

UNION ALL

First possibility:
IIf([GeoLocDE]="10.1","10.1"
,IIf([GeoLocDE]="11","11"
,IIf([GeoLocDE]="11.1","11"
,IIf([GeoLocDE]="11.2","11"
,IIf([GeoLocDE]="12.1","12.1"
,Int([GeoLocDE])))))) AS Loc

This could be generating an error if GeoLocDE is ever contains a value that
cannot be interpreted as a number. For instance, a zero-length string will
cause an error, as well as a value like 10.1.1 or 10-1.

AND this expression is generating a TEXT value. If you want a number value
then you need to strip out the quote marks in the 2nd argument to all those IIF's

IIf([GeoLocDE]="10.1",10.1
,IIf([GeoLocDE]="11",11
,IIf([GeoLocDE]="11.1",11
,IIf([GeoLocDE]="11.2",11
,IIf([GeoLocDE]="12.1",12.1
,Int([GeoLocDE])))))) AS Loc

Is PhysDate.Section a string field or a number field? If it is a number you
have to make the changes recommended.

PhysDat.Section is a string in the first SELECT, and a
number (single) in the UNION ALL SELECT!

Thank you so much! Off and running.
