Actually, just realized, this depends on your PGSQL version. 

 

The older format (pre-8.0 I believe) is SELECT ….. LIMIT x, y  (where x is the number of rows to fetch, and y is the offset (ie. Select x number of rows, starting from row y.)

SELECT ….. LIMIT 1

 

Will get the first row in the dataset.  Then to fetch the next row, you can do SELECT …… LIMIT 1 OFFSET 1 (will get the 2^nd record) and so on.

(replace ….. with your conditions, LIMIT must come at the end of the query)

Hi

 Is there any query for possibility of getting only one row at a time in a group of records?

 

With distinct rows & Columns my query has to return only one record at a time with out any condition.Will it be possible?

 

Thank you,
