2 SQL requests update fields of accounts table and one adds a payment into
bills table.

The requests are for PostgreSQL server using their native library.

As I add a transaction from 1001 to 1000 for the first time all is ok,
but for the second time the value of the variable(! according to the C language
syntax it is a variable even if it is a CHAR characters 1 dimenisional array)
SQL_from_account changes it value from 1001 to 1000(but it should not).

So if I press add(caption in cyrillic, but function names, etc are in english)

Why is this?
