Find rows where the value contains a word from a list of varchar(50)

问题

I am collecting data from a t-sql stored procedure to import into c# program. I would like to narrow down the data first. I have data that has three field that describes the three values that follows them. I need to find only the fields that have one of a dozen keywords in the description.

I was using something that UNION all the fields with values, then

...
AND (
        TEXT1234.AccountValue LIKE '%word1%'
     OR TEXT2345.AccountValue LIKE '%word1%'
     OR TEXT3456.AccountValue LIKE '%word1%'

     OR TEXT1234.AccountValue LIKE '%word2%'
     OR TEXT2345.AccountValue LIKE '%word2%'
     OR TEXT3456.AccountValue LIKE '%word2%'

     OR TEXT1234.AccountValue LIKE '%word3%'
     OR TEXT2345.AccountValue LIKE '%word3%'
     OR TEXT3456.AccountValue LIKE '%word3%'
...

Now I am trying to do something like this:

declare @wordList table (Word varchar(50))
insert into @wordList values ('%word1%'),('%word2%'),('%word3%')...

...
SELECT *
FROM [DB1].dbo.Table_info
WHERE Account = 'TEXT1234'
AND AccountValue LIKE (SELECT * FROM @wordList)
...

(This is one of a number of similar UNION pieces. Which is why I would like to use a list of words, to shorten the code, and contain the words in one place in case of future changes.)

OR something Like:

SELECT *
FROM [DB1].dbo.Table_info
WHERE Account = 'TEXT1234'
AND AccountValue CONTAINS (SELECT * FROM @wordList)
...

Expected output:

TEXT1234_Account   TEXT1234_AccountValue       Acct1234   Acct1234_Value
TEXT1234           word3 something something   ACCT1234   48

TEXT3456_Account   TEXT3456_AccountValue        Acct3456   Acct3456_Value
TEXT3456           Something word1 something    ACCT3456   48

Please let me know if you need more code to analyze this... (I am failing at keeping this brief already.)

回答1:

Use EXISTS:

SELECT *
FROM [DB1].dbo.Table_info tbl
WHERE tbl.Account = 'TEXT1234'
AND EXISTS
(
    SELECT 0
    FROM @wordList wl
    WHERE tbl.AccountValue LIKE wl.Word
)
