How to change the field type of result set from SQL pass-through (SPT)?

Question

I have a mysql table column defined as unit_price float(12,4) .

If I assign a value of 0.1234 , when I create a remote view with dbsetprop , I can retrieve 0.1234 with myview.unit_price .

However, when I use SQL pass-through (SPT) like this:

sqlexec(nHandle, "select * from table", "oResult")

the result of oResult.unit_price only shows 0.12 .

How can I ensure that I return the correct, full value?

Answer 1

Not having explicitly tried, you can do some simple math forcing to create larger precision, such as adding an additional column to your query... something like...

select *, unit_price * 1.00000 as UnitPrice5 from...

This will force the field to be computed to 5 decimal position and MIGHT actually change the result column to properly handle this forced decimal capacity. Then, you would use the "UnitPrice5" column instead of "unit_price"...

Don't know if that would be a big issue for you, but once it is in VFP, you have more control too.

Answer 2

The length of the decimal values are defined in your FoxPro settings. Go to Tools->Options->Regional and set the Decimal Digits to a higher value.
