The simplest way is to use TOP instruction.

SQL

SELECT TOP (135) <Field_list>
FROM TableName

Please, see: TOP (Transact-SQL)[^]

If you would like to add row number, use ROW_NUMBER()[^] function.

SQL

SELECT TOP (135) ROW_NUMBER() OVER(ORDER BY <FieldName>) AS RowNo, <Field_list>
FROM TableName

You can set the limit of rows via using ROW_NUMBER() function.

SQL

SELECT *
FROM (
    SELECT ROW_NUMBER() OVER(ORDER BY <FieldName>) AS RowNo, <Field_list>
    FROM TableName)
AS T 
WHERE RowNo<=135

In the same way, you can fetch data from defined range, for example:

SQL

DECLARE @rFrom INT = 136
DECLARE @rTo INT = 170
SELECT *
FROM (
    SELECT ROW_NUMBER() OVER(ORDER BY <FieldName>) AS RowNo, <Field_list>
    FROM TableName)
AS T 
WHERE RowNo BETWEEN @rFrom AND @rTo

I call it: 'custom pagination' ;)

I usually find it easier to add an integer auto increment column when I define the table (sometimes its also the primary key) - that way

a) when I insert a new row I have a unique value
b) I can use the value as a key if I need to

you can do a sql modify table to add the column (I think, depending on 'which sql flavour/variant' you're using) - then you'd need a small cursor update program to update the table and set the value incrementally - its a PITA - you then have to maintain it for all new rows added etc .. easier to have the value auto incremented for you on an insert imho

as solution 4 points out, row_number() should do what you want
