FieldByName returns integer instead of money

Sorry, I don't have much experience with TC connecting the DB's so I really can't comment

you can try

or create a support ticket

but I would try debugging what variable type is coming out of the DB and output it BEFORE you apply any conversion to it

https://support.smartbear.com/testcomplete/docs/reference/program-objects/aqobject/getvartype.html

testVar = Qry.FieldByName(paramName).Value

Log.Message(aqObject.GetVarType(testVar))

it looks like your DB collation maybe not be what you are expecting, some places use (and can set up the DB) ',' as the decimal seperator

e.g.

123.45 (Point 45)

123,456.78 (123 thousand)


Alternative DB collation

123,45 (Point 45)

123.456,78 (123 thousand)

in the latter case

223,00 would correctly evaluate to 223 as the .toFloat can't use the ',' collection as a decimal point are far as I know

- there appear to be 2 decimal places at zero and not 3 which would denote a thousand

you may have to change around , and . if this is the case
