CONTAINSTABLE动态OR条件SQL Server

Question

我想知道如何使用CONTAINSTABLE构建动态或条件？

计算chain0，chain1，chain2中的任何一个都可以为空，无论顺序如何。我想做(1 = 0) OR之类的事情...例如，第一个是空的，但它不起作用

例如

declare @chain NVARCHAR(MAX) = '' 
declare @chain0 NVARCHAR(100) = '(FORMSOF(INFLECTIONAL, "cat") AND FORMSOF(INFLECTIONAL, "dog"))' 
declare @chain1 NVARCHAR(100) = '(FORMSOF(INFLECTIONAL, "parrot") AND FORMSOF(INFLECTIONAL, "snake"))' 
declare @chain2 NVARCHAR(100) = '(FORMSOF(INFLECTIONAL, "pig") AND FORMSOF(INFLECTIONAL, "leon"))' 

IF @chain0 <> ''
BEGIN
    SELECT @chain = @chain + ' OR ' + @chain0
END

IF @chain1 <> ''
BEGIN
   SELECT @chain = @chain + ' OR ' + @chain1
END

IF @chain2 <> ''
BEGIN
   SELECT @chain = @chain + ' OR ' + @chain2
END

SELECT * 
FROM CONTAINSTABLE(TableAnimals, Title, @chain, @LenguageID) AS CT
