this not working when productable in pcode field add ant (-.&) kind of symbol want allow in pcode field, please me how can allow symbol in query

(problem code) update @availableqty set aqty=((ccqty-giqty)+(goqty)) ( select pc.pcode productcode, --goodsin (select case when sum(gi.quantity)is null 0 else sum(gi.quantity) end q goodsin gi pc.pcode=gi.productcode) giqty, --goodsout (select case when sum(gut.quantity)is null 0 else sum(gut.quantity) end q goodsout gut pc.pcode=gut.productcode ) goqty, --current stock (select cs.cqty q @closestock cs pc.pcode=cs.pcode ) ccqty producttable pc group pc.pcode )t prcode=t.productcode

the problem here isn't symbols you're using, it's assigning value of subquery single column in result set. example:

(select case when sum(pr.quantity)is null 0 else sum(pr.quantity)end q3 purchasereturn pr pc.pcode=pr.prdcode )as prrqty

note allowed if subquery returns single value; otherwise, don't know of values should assigned column.

if expect subqueries return multiple values , want arbitrary one, use top 1 in subquery return 1 value. otherwise, you'll have debug each subquery figure out returns multiple results , causing issue.
