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:

SQL

DECLARE c CURSOR FOR SELECT * FROM tbinstrument;

In MySql, have a look at Cursor DECLARE Syntax[^]

if i want to fetch rows into variable and with help of variable how can i access column value in ms sql server like following in oracle

DECLARE
CURSOR C IS SELECT * FROM TBTEST;
CV C%ROWTYPE;
BEGIN
OPEN C;
LOOP
FETCH C INTO CV;
EXIT WHEN C%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(CV.FIRST_NAME||CV.MID_NAME);

END LOOP;
CLOSE C;

END;

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.
