Fetch all records from #tbl1 which are not in #tbl2 without use of 'NOT' keyword
- Here we have two tables (#tbl1 and #tbl2)
Id Name --------- 1 Durgesh 2 Ashish 3 Ramesh 4 Steve 5 Pradeep
Id Name --------- 2 Ashish 5 Pradeep
Result Should be given below without using 'NOT' Keyword
Id Name --------- 1 Durgesh 3 Ramesh 4 Steve
Use the below Code :
SELECT Id,Name FROM #tbl1 EXCEPT SELECT Id,Name FROM #tbl2
The above code uses EXCEPT keyword to find the result. This query is Tested in SQL Server.
Need to fetch all the records of table “#Tbl1” which “DisplayId” not , Need to fetch all the records of table “#Tbl1” which “DisplayId” not present in from #tbl2 where displayid = t1.displayid) Notice the use of the alias t1, you do not if not that i want to insert a new row in respect to that roll no. create table # temp� Fetch all rows from the database table using cursor’s fetchall() Now, let see how to use fetchall to fetch all the records. To fetch all rows from a database table, you need to follow these simple steps: – Create a database Connection from Python. Define the SELECT query. Here you need to know the table, and it’s column details.
select A.id,A.name from #tbl1 A left outer join #tbl2 B on A.id = B.id where B.id is null
Using OFFSET and FETCH with the ORDER BY clause, All the examples for this lesson are based on Microsoft SQL Server If OFFSET is greater than the number of rows in the ordered results, then no rows are returned. One of the most popular uses for OFFSET and FETCH is paging. No doubt� The ONLY returns exactly the number of rows or percentage of rows after FETCH NEXT (or FIRST). The WITH TIES returns additional rows with the same sort key as the last row fetched. Note that if you use WITH TIES, you must specify an ORDER BY clause in the query. If you don’t, the query will not return the additional rows. Oracle FETCH clause
You can use
SELECT t1.* FROM #tbl1 t1 WHERE EXISTS (SELECT 1 FROM #tbl2 t2 WHERE t2.id <> t1.id);
Some DBMS supports lateral JOIN :
SELECT t1.* FROM #tbl1 t1 OUTER APPLY ( SELECT T2.* FROM #tbl2 t2 WHERE t2.id = t.id ) t2 WHERE t2.id IS NULL;
mysql_fetch_array - Manual, mysql_fetch_array — Fetch a result row as an associative array, a numeric that corresponds to the fetched row, or FALSE if there are no more rows. To access the other column(s) of the same name, you must use the numeric I have found a way to put all results from the select query in an array in one line colC = tbl2. Return Values. PDOStatement::fetchAll() returns an array containing all of the remaining rows in the result set. The array represents each row as either an array of column values or an object with properties corresponding to each column name.
Use a left outer join in FetchXML to query for records „not in , Example: Find all leads that have no tasks, using an alias. The following shows how to construct the query in FetchXML: XML Copy. FETCH Statement. The FETCH statement retrieves rows of data from the result set of a multiple-row query—one row at a time, several rows at a time, or all rows at once—and stores the data in variables, records, or collections.
This is a terrific answer, as it does not require returning all rows of Table2! – dotancohen Dec 8 '13 at 18:47 I agree, great answer. I have a man-many table between 4 tables, putting the AND in the inner join is most definitely going to be more economical.
- Tag the DBMS that you are using.
- Welcome! You can use joins as well for your purpose.
