The result set below should only show the complete records for each account. There are only 2 rows in Table 1, and if you run the subquery separate it returns only 2 rows, so I’m confused why 4 rows are being returned. It should return the docID, docTitle, and the associated content record with the newest 'dateAdded' value. If you want to get the latest records from log for each name then this cant be performed by queries only in an easy way (at least within MySQL dialect). I would like to get a list of all the documents, with the latest content joined. How do I join on 'most recent' records Ive got two tables in a SQL Server 2000 database joined by a parent child relationship. This way there is a complete history of all changes. RIGHT OUTER JOIN Results are from the right table and matching data from the. LEFT OUTER JOIN Results are from the left table and matching data from the right table. INNER JOIN Results return matching data from both tables. I want to get the most recent record (or last record) for each account from Table 2, and then join that data to Table 1. For every content change, a new record is inserted into the 'content' table. There are several MySQL JOIN types, and each type helps get different results when joining tables: 1. ON (t1.parent_id = t2.parent_id and t1.datestamp < t2.I’m not sure how to explain what I did, but I joined the data in Table 2 to Table 1, instead of joining the data from Table 1 to Table 2, and it worked. Very often we need to select the most recent record or get the latest record for each date, user, id or any other group. Or join the parent table directly into it: SELECT parent.*, t1.* ON (parent.id = most_recent_children.parent_id SELECT tbl.MachineName ,tbl.DateColumn ,tbl.Column3 -,tbl. WHERE t2.datestamp IS NULL ) AS most_recent_children The record you want to see is the one with the latest information (determined by the date column) The following generalized query will allow you to do this. ago If using SSMS, you could use rownumber to do it as well. 9 17 comments Add a Comment Ddcooljoe 4 yr. In our example, the most recent row always has the highest id value. left join and return only the latest record from right table IDDETAILS SUBIDDETAILS result that i want: I want to return only the latest and only one record per sub ID from right table. You can use that table in a subquery to join to: SELECT * Joining the First Row is an oft-used technique and a vital tool in the analysts. That gets you all of the rows in the child table for which no higher timestamp exists, for that parent id. ON (t1.parent_id = t2.parent_id and t1.datestamp < t2.datestamp) Something like this (your SQL dialect may vary): SELECT t1.* Select only the most recent order for each customer by filtering the records with row numbers equal to 1. FROM ARTICLES AS t -Join the the most recent history entries INNER JOIN REVISION lastHis ON t.ID lastHis.FKID -limits to the last history in the WHERE statement LEFT JOIN REVISION his2 on lastHis.FKID his2.FKID and lastHis.CREATEDTIME < his2.CREATEDTIME WHERE his2.ID is null. You can make a table like that by joining the child table on itself, taking only the maximum datestamp for each parent id. If you had a table which just contained the most recent entry for each parent, and the parent's id, then it would be easy, right?
