The INTERSECT operator is supported by Oracle and SQL Server, but not by Microsoft Access.
what is intersect command?With the UNION clause in SQL, all matching rows from two SQL queries are combined into a single table.
In order to combine, the two searches must return the same number of columns and compatible data types. Unless UNION ALL is used, all duplicate records are immediately deleted.
In data warehouse applications where tables are not properly normalized, UNION can be helpful.
[2] A straightforward illustration would be a database with two tables, sales2005 and sales2006, which are separated for performance reasons despite having identical architecture. The output from both tables might be combined with a UNION query.
Keep in mind that the rows' order is not guaranteed by UNION ALL. Rows from the first operand may be mixed in with rows from the second operand or may come first. In.
Hence, The INTERSECT operator is supported by Oracle and SQL Server, but not by Microsoft Access.
