TSQL搜索多個條件

Question

我瞭解到，我可以使用類似搜索多個領域：

DECLARE @srch nvarchar(40) 
    SET @srch = '%something%' 

SELECT * FROM DataTable dt 
    WHERE CONCAT(dt.field1, dt.field2) LIKE @srch 

但是，有沒有方法來搜索比多手術室等多重標準？

DECLARE @srch1 nvarchar(40), @srch2 nvarchar(40), @srch3 nvarchar(40), 
    SET @srch1 = '%this%' 
    SET @srch2 = '%that%' 
    SET @srch3 = '%the other%' 

SELECT * FROM DataTable dt 
    WHERE CONCAT(dt.field1, dt.field2) LIKE @srch1 
     OR CONCAT(dt.field1, dt.field2) LIKE @srch2 
     OR CONCAT(dt.field1, dt.field2) LIKE @srch3 

謝謝！

Answer 1

這個怎麼樣？

DECLARE @srch TABLE (srch_field nvarchar(40)) 

INSERT INTO @srch VALUES ('%this%'), ('%that%') ,('%the other%') 

SELECT * FROM DataTable dt 
WHERE EXISTS (
    SELECT NULL FROM @srch s WHERE CONCAT(dt.field1, dt.field2) LIKE srch_field 
)
