I have list of Heads like A, B, C, D....
and like to insert in a table with three column COMCOD, SIRCODE, DESCRIPTION
Primary key SIRCODE nchar(12) and starts from '1802000001000' , next '1802000002000', next '1802000003000' and so on. The will look like
COMCOD SIRCODE DESCRIPTION
3306 1802000001000 A
3306 1802000002000 B
3306 1802000003000 c

Where is the "list of Heads"? Is it in a normalized table or in a single "cell" of a table or in a single variable. If either of the latter two, how is it stored? As a CSV, TSV, Fixed Width multi-entry or what?

As a bit of a sidebar and although I know you probably can't change it, I think it a bit insane to store numbers only values that need to be incremented (and, therefor, calculated) in an NCHAR column for several reasons. NCHAR usually makes no difference on numeric values, requires some special handling to increment, and wastes space because it requires 2 bytes per character. Your NCHAR(12) definition of this column occupies 24 bytes as opposed to just 8 bytes that would be used by a BIGINT.

Last but not least, your SIR Code appears to have a prefix and a sequence as a suffix. That also means that you have to use substring to split the 2 component parts out of the code for reporting. It would be a far better thing to store the 2 parts in separate columns and use a persisted computed column to put them together for display or reporting purposes.

If you can answer my questions as to "where" the "list of heads" is and what format it's in that I've identified in the first paragraph of this response, I'm positive that someone will be able to show you a relatively easy method to satisfy your requirements even if they, too, don't agree with the structure of the table.

I like to insert SIRCODE in Sequence like x= x+1000

Then it look like

Comcod Sircode Sirdesc

3306 100001000 A

3306 100002000 B

3306 100003000 C

Yes. We know that. Please see my previous post. We need to know where the "List of Heads" of A, B, C, D "lives" and what format it is in.

"List of Heads" of A, B, C, D data type is nvarchar(250)

"List of Heads" of A, B, C, D data type is nvarchar(250)

Where does this data come from?

Thanks. I just got off from work and, if someone doesn't beat me to it (lots of capable folks on this forum), I'll give it a shot after work tomorrow night.

Lynn is correct, though. Is the "list of heads" in a table column that way or just in a single variable?
