The following picture illustrates A UNION B: Using Result Of One Query In Another Sep 29, 2004. hi, i've tried searching on this but not having much luck, i'm trying to use the result of one and use it in another. To retain the duplicate rows in the result set, you use the UNION ALL operator. Query result: The result of the query is 80. In order to use the MINUS operator, the columns in the SELECT clauses must match in number and must have the same or, at least, convertible data type.. We often use the MINUS operator in ETL. An ETL is a software component in data warehouse system. The first sql query runs on DB1 that exists on server1. To make the result set, the database system performs two queries and subtracts the result set of the first query from the second one. In the original SQL standard, a comparison could have only one … I think I read using an array ight be the answer but I dont know, please help. and how to do it ? I need query 2 to run using each result from query 1 in the where condition. For example my sql query returns some values as - Using the result of this query, here we have written another query to identify the students who get better marks than 80. I need to make three select queries over three different tables, using the outputs of each select query, the catch is each one gives multiple results. UNION – Use Unions and other set operators to combine rows from one or more queries into one result. JOIN – You can use joins to combine columns from one or more queries into one result. how to do that ? The subquery returns a single value: the average list price in the PRODUCT table. The latest one, An Easier Way of Pivoting Data in SQL Server, inspired me to start exploring another option to transpose a result from a query. Here is how I do it. Here is the query : Second query: SELECT a.studentid, a.name, b.total_marks FROM student a, marks b WHERE a.studentid = b.studentid AND b.total_marks >80; Query result: is there any way to do this? The first query output looks something like this: 2 5 7 8 query is like: select something from somewhere where field = '2'; Then I need to run another query: select something from somewhere else where field = 'result of the last query output'; I can do this with php, but i'm wondering if there's a one shot way to do it through mysql? To eliminate the duplicate rows, the database system sorts the combined result set by every column and scans it for the matching rows located next to one another. Can someone help me to do this. i have to use query cascades ? I have a sql query that returns some values and I need to use those values as inputs to another SQL select statement. I want my web page to run the sqlquery1 and take the results of the query. plz i really need this query to continue my project Navigate: Previous Message • Next Message Select "Title", "Num" from "Table" where "Id" in ( Select "Id" from "Table2" where "Id" in ( select distinct "Id" from "Table3" where foo-clause ) ) Actually, another way of writing my first suggestion would be: What I want to do is take that list of 10 jobs, and use that as input into the following query to get the details of each failed run: Sub Queries – Sometimes called nested queries, these can be used to perform a separate search in the database showed results can be used in another query. The outer query retrieves all rows from the PRODUCT table that have a lower list price than the average list price. I like Phil Factor’s articles. There are many situations in which the results of a query look better when they are rotated. Suppose, we have two result sets A(1,2) and B(2,3).
