It is a query inside another query. Normally it is a select statement inside a query. Sometimes you want to run query and use data from another query in that query. So you will have one query inside another one. The inside or nested query is the subquery.
In MS Access, a Query is a saved search, which can be used in reports, etc.
It uses a version of SQL. (Structured Query Language).
You can use the Create Table Wizard, a Make Table Query or a Data Definition Query as ways that are built into Access to create tables.
Yes, you can have a query inside a query. That is known as a sub-query.
You can use the Max function and the Min function in a query to do it. They are both available when you use the Totals row in the query design grid.
To return multiple columns from a sub-query, you can include the sub-query in the SELECT statement of your main query. For example, you can use the sub-query in the FROM clause or as a derived table, specifying the columns you want to select. Ensure that the sub-query is properly formatted to return the desired columns, and you can alias it if necessary to improve readability. Here's a basic example: SELECT a.column1, a.column2 FROM (SELECT column1, column2 FROM table_name WHERE condition) AS a;
This is called a correlated sub-query.
In MS Access, to display specific records from a table that meet certain criteria, you can use a query. You can create a select query by using the Query Design view or SQL view, where you specify the table and the fields you want to display. In the criteria row of the relevant field, you can input conditions (like specific values or ranges) to filter the records accordingly. Running the query will then show only the records that match your defined criteria.
SQL - Structure Query Language for MS Access is not as robust as you get on some other RBMS like MS SQL Server, Oracle etc. SQL gives you the flexibility of of data definition and manipulation using script. Pelumi (Nigeria)
