The cursor is quite similar in other systems. In Sql Server, have a look at DECLARE CURSOR[^]

So your cursor definition would look something like:
DECLARE c CURSOR FOR SELECT * FROM tbinstrument;
In MySql, have a look at Cursor DECLARE Syntax[^]

There's no direct equivalent for ROWTYPE in Sql Server. One way is to declare a table type variable, see DECLARE[^] or to list the columns and fetch the values into separate variables.
