Select * from table where column = (any value from a comma delimited string) - sql

Question

The user selects various words from a drop down list and these values get added into a comma delimited string. When passing the string to a stored procedure I want it to select * from a table where that word exists.
Table
id----word
1-----cat
2-----dog
3-----mouse
4-----dog
string that is passed into the stored procedure is cat, dog so returning columns 1, 2 and 4.
Is there a way of doing this in sql server?

Answer 1

Use IN:
SELECT *
FROM your_table
WHERE word IN ('cat', 'dog')

Answer 2

you first need to make a function SplitCSV :
CREATE FUNCTION [dbo].[SplitCSV] (#CSVString VARCHAR(8000), #Delimiter CHAR(1))
RETURNS #temptable TABLE (items VARCHAR(8000))
AS
BEGIN
DECLARE #pos INT;
DECLARE #slice VARCHAR(8000);
SELECT #pos = 1;
IF LEN(#CSVString) < 1 OR #CSVString IS NULL RETURN;
WHILE #pos!= 0
BEGIN
SET #pos = CHARINDEX(#Delimiter,#CSVString);
IF #pos != 0
SET #slice = LEFT(#CSVString, #pos - 1);
ELSE
SET #slice = #CSVString;
IF( LEN(#slice) > 0)
INSERT INTO #temptable(Items) VALUES (#slice);
SET #CSVString = RIGHT(#CSVString, LEN(#CSVString) - #pos);
IF LEN(#CSVString) = 0 BREAK;
END
RETURN
END
GO
then you can use it like :
SELECT *
FROM myTable
WHERE ID IN (
SELECT items FROM [dbo].[SplitCSV]('1,2,3,4,5', ',')
)

Answer 3

SELECT *
FROM Table
WHERE '%,' + Word + ',%' LIKE ',' + #your_csv_param + ','
Extra commas at the begin and end of parameter and column are to prevent search to match cat with catfish for example.

Answer 4

If you want select all animal except mouse , you can use NOT IN
SELECT * FROM
TABLE
WHERE Word Not IN('Mouse')
So you can avoid type many type of animal

Answer 5

CREATE FUNCTION
ALTER FUNCTION [dbo].[fn_Split](#text varchar(8000), #delimiter varchar(20) = ' ')
RETURNS #Strings TABLE
(
position int IDENTITY PRIMARY KEY,
value varchar(8000)
)
AS
BEGIN
DECLARE #index int
SET #index = -1
WHILE (LEN(#text) > 0)
BEGIN
SET #index = CHARINDEX(#delimiter , #text)
IF (#index = 0) AND (LEN(#text) > 0)
BEGIN
INSERT INTO #Strings VALUES (#text)
BREAK
END
IF (#index > 1)
BEGIN
INSERT INTO #Strings VALUES (LEFT(#text, #index - 1))
SET #text = RIGHT(#text, (LEN(#text) - #index))
END
ELSE
SET #text = RIGHT(#text, (LEN(#text) - #index))
END
RETURN
END
----
select * from yourtable where column in ( select value from fn_Split(#para1,',')
