The following query will output 2 word that's close in position, but how can I output 3 word that's close in position instead of 2 word? the query will have 3 column output instead of 2 column output for words.
SELECT A.word As word1, B.word AS word2, A.document
FROM Data AS A
JOIN Data AS B
ON A.document = B.document
AND A.position < B.position
AND ABS(A.position - B.position) < 3;
Notes on Table and output:
I have a Table stores keywords + position of the word + document number 1 or 2 ... the word in.
Word Position Document Great 1 1 Wall 2 1 China 3 1 Dog 3 2 Cat 7 2
I would like to output all word that are close related ... position of 2 word do not more than 3 word apart :
The output should be:
Great Wall 1 Wall China 1 Great China 1Received on Wed Feb 25 2009 - 01:03:18 CST
