while loop in procedure sybase

Question

In oracle when we write a procedure we do it like this :

COUNT_START:= LL_COUNT;
WHILE LL_COUNT > 0 LOOP
IF LL_COUNT > 20 THEN
COUNT_START := 20;
ELSE
COUNT_START := LL_COUNT;
LL_COUNT := 0;
END IF;

I am writing a procedure in sybase :

  CREATE PROCEDURE P_RDS_EOD_ARCH_PURGE
  v_test numeric(10,0)

 AS

 BEGIN

 DECLARE @ID VARCHAR(200)
 DECLARE @NAME VARCHAR(200)
 DECLARE @TYPE VARCHAR(200)
 DECLARE @SQL_TXT VARCHAR(255)


 SELECT @ID   = '1' 
 SELECT @NAME = 'P_TEST'
 SELECT @TYPE = 'SELECT'

 SELECT @SQL_TXT ='RANDOM QUERY'

 EXECUTE @ID, @NAME , @TYPE, @SQL_TXT

After I execute my query I want to do a LOOP and to assign values, how to do that in sybase

Answer 1

Loops are pretty basic in TSQL:

while boolean_expression 
  statement

If your statement is more than 1 line, then you can enclose it in begin/end statements;

while aStatementIsTrue
begin 
   update myTable
   set myCol = "whatever"

   select someOtherThing
end

More details can be found in the Sybase T-SQL User's Guide.
