我想使用游标将TableA中的值复制到TableB,但总是遇到麻烦。这是我的代码:
DROP TABLE #Firmy
DROP TABLE #Faktury
CREATE TABLE #Firmy (
idfirmy VARCHAR(255)
)
INSERT INTO #Firmy VALUES ('00001936')
INSERT INTO #Firmy VALUES ('00002059')
CREATE TABLE #Faktury (
idfirmy VARCHAR(255)--,
--idfaktury VARCHAR(255)
)
DECLARE fakturyc CURSOR FOR SELECT * FROM #Firmy
FOR loop1 AS fakturyc
DO
INSERT INTO #Faktury VALUES fakturyc
END FOR
获取" loop1"附近的语法错误。有人可以帮我解决这个问题吗?谢谢:))

这实际上是T-sql:但也可以在sybase中使用
DROP TABLE #Firmy
DROP TABLE #Faktury
CREATE TABLE #Firmy (
idfirmy VARCHAR(255)
)
INSERT INTO #Firmy VALUES ('00001936')
INSERT INTO #Firmy VALUES ('00002059')
CREATE TABLE #Faktury (
idfirmy VARCHAR(255)--,
--idfaktury VARCHAR(255)
)
declare @col1 varchar(10)
declare copy cursor for
select idfirmy from #Firmy -- select top 1 * from #Firmy
open copy
fetch next from copy into @col1
while @@FETCH_STATUS=0
begin
insert into #Faktury(idfirmy) values(@col1)
fetch next from copy into @col1
end
close copy
deallocate copy
select * from #Faktury
select * from #Firmy
simplified Query
将是
insert into #Faktury
select * from #Firmy
