This WHILE loop continues for as long as the specified conditions are true or until the code specifically terminates the loop using the BREAK keyword.Loops in Synapse SQL are useful for replacing cursors defined in SQL code. Fortunately, almost all cursors that are written in SQL code are of ...
T-sql For in loop 变量循环语句 For 变量 in 循环开始的值 .. 循环结束的值(小于该值) Loop --做处理的语句 End Loop 例子: ---循环找出供应商 for i in 0 .. vendor_Total loop-- i 和 vendor_Total 在存储过程头部定义,vendor_Total 在循环之前已经赋值 if i = vendor_Total then str_vendor ...

while instr(str_vendors, ':') > 0 loop vendor_Total := vendor_Total + 1; vendors_len := instr(str_vendors, ':'); str_vendors := substr(str_vendors, vendors_len + 1, length(str_vendors) - vendors_len); end loop; while instr(str_VASSIGNs, ':') > 0 loop ...
引用 1 楼 wwwwa 的回复:不能实现，用CASE WHEN代替相似 的有ITERATE,and LEAVE ITERATE labelITERATE can appear only within LOOP,REPEAT,and WHILE statements.ITERATE means “do the loop again.”Example:CREATE PROCEDURE d……谢谢！！我得想想其他办法，来修改咯！
When executing the procedure from a Transact-SQL batch or another stored procedure, avoid using a cursor with the natively compiled stored procedure. When creating a natively compiled stored procedure, rather than using a cursor, use set-based logic or aWHILEloop. ...
Oracle中的LOOP语句 Oracle PL/SQL支持多种循环结构,包括基本的`LOOP`语句、`WHILE`循环和`FOR`循环。 **LOOP语法**: ```plsql DECLARE counter NUMBER := 0; BEGIN LOOP counter := counter + 1; DBMS_OUTPUT.PUT_LINE('Counter: ' || counter); EXIT WHEN counter >= 5; END LOOP; END; / ``...
在Oracle中,可以在PL/SQL块中使用LOOP、WHILE LOOP或FOR LOOP。LOOP 循环示例DECLARE counter NUMBER := 0; BEGIN LOOP EXIT WHEN counter >= 10; -- 这里写你的逻辑代码 counter := counter + 1; END LOOP; END; WHILE LOOP 循环示例DECLARE counter NUMBER := 0; BEGIN WHILE counter < 10 LOOP --...
