Hi,
I have three different data types coming out of my SQL tables that I
need to align with my VB code and the data set properties. I'm
getting an error message that reads "SQL exception unhandled. The
data types text and nvarchar are incompatible in the equal to
operator." Here is the relevant code.
Dim da As New SqlDataAdapter( strSQL, cn)
da.SelectComman d.Parameters.Ad dWithValue("@Or derID",
tbOrderID.Text)
Dim tbl As New DataTable("Orde rs")
With tbl
.Columns.Add("O rderID", GetType(String) )
.Columns.Add("P rice", GetType(Decimal ))
.Columns.Add("I tem", GetType(Integer ))
End With
da.Fill(tbl)
Previously, I had all of the fields set to text in SQL, String in the
VB code and System.String in the data set properties. Everything
executed fine. However, when I tightened up my data types, attempting
to change them to their correct types, the app crashed. That was the
only thing that I changed between successful runs and the run-time
error.
So I suspect that I just have some sort of contradiction in how I have
set the data types in the various settings (sql, vb code, data set).
I have attempted to synchronize these data types using:
Text (sql), String (vb code), System.String (data set
properties);
Money, Decimal, System.Decimal;
Int, Integer, System.Int16.
No matter what I try, I get the exact same error.
Am I right or is the error message coming from somewhere else? Also,
does anybody know of a reference that shows what data types are
"legal" matches between these different settings?
I appreciate any help.

Suggestions and all kinds of recomendations are more than welcomed.
If it all goes ok, it'll be a PEP when I finish writing/modifying the code.
Thank you.

Evening all,
I'm trying to add a new built-in number data type to Python with its own
syntax, so I'm working directly with the interpreter rather than
creating my own extension module (side note: I've appended something
extra to the version thing in the Makefile - I doubt this is relevant to
the problem but it's probably best you have all the info). The complex
data type is similar to what I'm trying to do so I've been following
that as...

Hey folks,
To me, this sounds like a crazy question, but I'll throw it out there
anyway.
Is it possible to change a variables data type half way through a running
program? If so, how?
You're probably thinking why would you ever want to do that. Valid
question. If you're curious why I'd like to do it, read on. But otherwise,

I have several stored procedures with parameters that are defined with
user defined data types. The time it takes to run the procedures can
take 10 - 50 seconds depending on the procedure.
If I change the parameter data types to the actual data type such as

return records. The user defined types are mostly varchar, but some
others such as int. They are all input type...

Hi Group, I've got a problem I couldn't find a good solution. I am
working with scientific data files in netCDF format. One of the
properties of netCDF data is that the actual type of data is only known
at run time. Therefore a lot of template based trick isn't too useful.

Hello,
I would like to create a user XSD data type that inherits from the w3

always contains distinct values. The problem is I would like this

type does not allow spaces.
How can I inherit ID and also allow the entry of spaces in the data of
a new derived data type? This is a title column where I...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
