我需要在我的Function中创建一个条件，如果是真的，请使用一个sql语句，如果不使用另一个，但是我遇到了问题。我的功能代码：
ALTER FUNCTION [dbo].[FN_TODAS_SMP]
(
@STATUS TINYINT,
@VALOR_CARGA DECIMAL(12,2),
@PLACA VARCHAR(10),
@NUMERO_SMP INT,
@WORKFLOW CHAR(1),
@DESC_FROTA_CLIENTE VARCHAR(25),
@FILTRAR_PLACA BIT,
@FILTRAR_SMP BIT,
@FILTRAR_VALOR BIT,
@FILTRAR_WORKFLOW BIT,
@FILTRAR_FROTA BIT,
@ID_USUARIO INT,
@FILTRA_REGIOES BIT,
@IS_REGIONALIZADO BIT
)
RETURNS TABLE

run another SQL
但是我在“IF”处遇到了“不正确的Sintax”错误，您是否知道我必须如何处理呢？
答案 0 :(得分：0)
你在使用BEGIN＆amp;结束.. EG：
if condition = true begin
select statement one
end
else begin
select statement two
end
答案 1 :(得分：0)
此处有一些选项：https://stackoverflow.com/a/1558192/2773046
Common Table Expressions只能跟着我害怕的SELECT，INSERT，UPDATE，DELETE或MERGE语句。
