Hi,

I have a SQL Table , in that one of the col is Material (INT).

Now, My task is i want to take a list of materials into ListBox, and then i select some of them, and then insert in to my table is it possible.

for ex:

varchar --- 'a,b,c,d' --- its inserted why bcz with in the single quotation we
are passing N no.of values means it's consider as a single
parameter.

similarly

int --- 1,2,3,4 --- has to be inserted into my table in a single insertion only.

can any one help me to do this..

Thanks in advance...

Do you really want to insert multiple values into one column in one single row? Then you decided for a very bad design: read about "normalization"!
Better use one value for the column per row, and use a "transaction" to make sure that all values are inserted (or none in case of failure).

Then change the column to varchar and treat the int as string.

By the way, when the numbers are small numbers like those you showed, you could treat them like "flags": calculate 2^number for each number, sum that up, and store the result.
