SET NOCOUNT ON;

DECLARE @ssn char(9)
DECLARE @Code char(3)
DECLARE @DateEntered char(9)


Hello, I have a simple table with three columns. The table only has like 6 records in it at this time. All I want to do is to read the contents of the table into a cursor, and then dump out the data. I am running the below script from query analyzer, but it appears to be stuck in an infinite loop. Can someone look at my cursor code, and tell me if it is broken?


PRINT '--------  Report --------';

DECLARE people_cursor CURSOR FOR
SELECT SSN, Code,DateEntered
FROM People
ORDER BY DateEntered;

OPEN people_cursor

FETCH NEXT FROM people_cursor
INTO @ssn, @Code, @DateEntered

WHILE @@FETCH_STATUS = 0
BEGIN

      PRINT @ssn
      PRINT @Code
      PRINT @DateEntered

    CLOSE people_cursor
    DEALLOCATE people_cursor

END

I see at least 2 issues:
-close/deallocate goes outside the loop
-you are not refetching the next row in the loop

DECLARE people_cursor CURSOR FOR 
SELECT SSN, Code,DateEntered
FROM People
ORDER BY DateEntered;

OPEN people_cursor

FETCH NEXT FROM people_cursor 
INTO @ssn, @Code, @DateEntered

WHILE @@FETCH_STATUS = 0
BEGIN

      PRINT @ssn
      PRINT @Code
      PRINT @DateEntered

     FETCH NEXT FROM people_cursor 
     INTO @ssn, @Code, @DateEntered

END

    CLOSE people_cursor
    DEALLOCATE people_cursor
