Pass the output of one query to another query (2024)

FAQs

How do you use the result of a query in another query? ›

Use the results of a query as a field in another query. You can use a subquery as a field alias. Use a subquery as a field alias when you want to use the subquery results as a field in your main query. Note: A subquery that you use as a field alias cannot return more than one field.

The first query needs to go as a subsearch (the part in []) and return the needed field back to the main search (which in your case is the second query). You can select which field to use as a result in the main search with the return command. Normally it would look something like "field=value1 OR field=value2 OR ...."

How to fetch data that are common in two query results ? select * from EMPLOYEE where EMPLOYEE_ID INTERSECT select * from EMPLOYEE where EMPLOYEE_ID < 4 Explanation: Here "INTERSECT" command is used to fetch data that are common in 2 queries.

You should separate the parameters after the WITH_PARAMS keyword with commas. The order of the parameters that you define after the WITH_PARAMS keyword corresponds to the order of the ? characters defined in the SQL query. You can repeat the parameters so that the same parameter can be used multiple times in the SQL.

Comparing the Results of the Two Queries

The solution to this is very simple. Run both queries using a UNION to combine the results! The UNION operator returns unique records. If the two results sets are identical the row count will remain the same as the original query.

Can we fetch data from multiple tables using one query? ›

To retrieve information from more than one table, you need to join those tables together. This can be done using JOIN methods, or you can use a second SELECT statement inside your main SELECT query—a subquery.

SQL SELECT statement is used to fetch the data from a database table which returns data in the form of result table. These result tables are called result-sets. The SQL WHERE clause is used to specify a condition while fetching the data from single table or joining with multiple tables.
