Query Producing Incorrect Results

Question

Hello:
I am trying to perform a number of queries on a database and
although I am not receiving an error message; I know that the
returned results are incorrect.
For example, in my test data; I have only 1 record that
matches the SchoolBoardID (Therefore the record could only have one
grade, one gender, etc. yet my queries are returning results for
both genders (Male and Female) and multiple grades (11 and 12) when
the record in question actually has a grade 9 assignment.
I have looked at my code over and over and I cannot find
where the problem is; does anyone see anything that jumps out at
them?
I am using an MS-Access database and I have the following
data types for the relevant fields in question.
Field Name = SchoolBoardID - Numeric - Sample Data - 74
Field Name = StudentTraineeGender - Data Type = Text - Sample
Data - Either Male or Female
Field Name = StudentTraineeGrade - Data Type = Text - Data
Contains the following (9, 10, 11, 12, 12+ Hence the reason for
having to use a Text data type)
Field Name = SchoolYear - Data Type = Text - Sample Data -
2006-2007
Field Name = TradeCode - Data Type = Text - Sample Data -
444A
Field Name = TeacherWEAApproval - Data Type = Yes/No - Sample
Data - 1 or 0

Thank you for any assistance that you can lend me with

Answer 1

Hello:
SchoolBoardID is unique in that there is only 1 record in the
WEA_Registrants table containing it; however, it was my intention
with my queries to have the potential for more that one query to
have a positive recordcount. (i.e. It would be possible for
#GetGrade11Males.RecordCount# and
#NumberOfMaleRegisteredApprentices# and
#NumberOfMaleRegisteredApprenticesGraduated# to all return positve
record counts.

Sounds like there may be more to this issue than you are
leading us to believe.
To the best of my knowledge, I have presented
all of the relevant information.
I will look into the documentation on cfqueryparam.
Thanks for your assistance.

Chizzy
