我正在尝试使用'和'在If条件中如下:
Begin
If condition1 and condition2
then begin result1
end else begin result2;
End;
end;
声明中有什么问题。任何人都能帮忙解决这个问题吗?谢谢!

作为一个疯狂的猜测,失去了'然后' (SFrejofsky的评论),并失去了第一个;它位于begin..end块的内部。
此外,如果块中只有可执行行,则不需要begin..end,因此您的代码应如下所示
If condition1 and condition2
result1
else
result2

删除THEN
。实施例
DECLARE @variable INT = 0
DECLARE @variable2 INT = 10
IF @variable > 0 AND @variable2 > 0
BEGIN
SELECT 'Condition was met'
END
ELSE
BEGIN
SELECT 'Condition was not met'
END
如果您想链接IFs
:
DECLARE @variable INT = 0
DECLARE @variable2 INT = 10
IF @variable > 0 AND @variable2 > 0
BEGIN
SELECT 'Condition 1 was met'
END
ELSE IF @variable = 0 AND @variable2 > 0
BEGIN
SELECT 'Condition 2 was met'
END
ELSE
BEGIN
SELECT 'No condition was met'
END
此外,如果您只需要一个语句,则可以避免使用BEGIN
... END
,但如果表达式很长,则可能很难理解。
DECLARE @variable INT = 0
DECLARE @variable2 INT = 10
IF @variable > 0 AND @variable2 > 0
SELECT 'Condition was met'
ELSE
SELECT 'Condition was not met'
