Hi,
I want to change the datatype of an existing column from char to
varbinary. When I run the "Alter Table" statement, I get the
following error message -
Disallowed implicit conversion from data type char to data type
varbinary, table 'test.dbo.testalter', column 'col1'. Use the CONVERT
function to run this query.

Hi,
I have tables named like ag97a027, ag98a027, ... where 97 and 98 is
from year 1997, 1998 and a027 is just specification of product type. I
need carry out repeated operataions over these tables. To generate
their names is easy, for example
use
declare @Yint int, @Y char(2), @tabName char(8)
set @Yint = 1997
while @Yint < 2002

Hi all,
Just trying to get a feel here. THe shop I work at insists on
prefixing all column names with the table name, so it is order_id in
the ORDER table and Customer_id in the CUSTOMER table.
I find this irksome and much prefer that a coding standard be imposed
whereby any column name has to be qualified by the table name. So it
would be...

The following code sets a DataTable column DataType to "String"
column.DataType = System.Type.GetType("System.String");
What is the corresponding statement when the data type is boolean? I have
tried both "bit', "bool", and "boolean" and all cause an error.
One would think that a simple search for "System.Type.GetType" in Books On

Greetings,
I've seen this question asked and answered here, just not completely yet.
I'm wondering how to use a column value as a table name in another query. So far it's looking like you must use dynamic SQL, external to DB2.
An example: TableX contains column TabName, which is populated by the names of tables in the database. Each of...

I built a webpage using vb.net (.net 2.0) that creates a form letter. This
letter pulls data from a database. Although I populate the address with the
person's full name, which comes from the name column of a customer table, I
need to just get the first name for the Dear part of the letter (ie: Dear
John instead of Dear John Smith). It would...

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. ...
