How to search value from a particular column in a data base table

Question

See more:

I want search code which will find all the text which is similar to a column in a table. PL/SQL also can applicable.

Example:
Suppose, I have 3 text in a column (Sample_text) of a table. I want to search 50 to 80 percent similarity text form a given text.

1. a. The Safety gate combined with one gate.
b. The Safety gate combined with three gates.
c. The Safety gate separated with others gates.

1. Output:
The Safety gate combined with one gate.
The Safety gate combined with three gates.
The Safety gate separated with others gates.

If I search through the text, "The Safety gate combined with one gate" then it will show all the three above text. Because those three text have more than 70 percent similarity in between those above three text.

But,

2. a. Important! save for (new AMII).
b. Important! keep instruction (AMII).

Output:
No match found.

Those couple of text does not have the 50 percent similarity in between that.
So, it will show nothing.

Not clear. If you post an example it might help - post the sql you have already tried to give us a clue

Solution 1

My best shot:

SQL

SELECT *
FROM TableName
WHERE ColumnData Like '%The Safety%'

I tried above on below example:

SQL

DECLARE @tmp TABLE (SomeText VARCHAR(255))

INSERT INTO @tmp (SomeText)
VALUES('1. a. The Safety gate combined with one gate.'),
('b. The Safety gate combined with three gates.'),
('c. The Safety gate separated with others gates.')

SELECT *
FROM @tmp
WHERE SomeText Like '%The Safety gate%'

See: Like (T-SQL)[^]

I used that one. But it has not fulfilled the exact requirement. See the example I given above.

I gave you an answer here: How to search 50% to 80% from a database column which has contained lots of paragraph text.
Simil is what your looking for.

I know. I want it in SQL only. Search engine optimization in pl/sql.
