We use them with caution when portability to other databases is a concern or referential integrity is a concern. If subquery produces a SQL table, the table must have exactly one column. The PL/SQL programming language provides a data structure called the VARRAY, which can store a fixed-size sequential collection of elements of the same type.A varray is used to store an ordered collection of data, however it is often better to think of an array as a collection of variables of the same type. By default, an Array value is a transaction-duration reference to an SQL ARRAY value.

They were disappointed and asked me how was this problem handled. As you can see, SQL Server does not include arrays. expr Is the expression to be found. The path argument can include an optional path mode component. Ordinary arrays have a user-defined upper bound. This operator does not support wildcards, though, so you only can check for exact matches. To insert values into an array column, we use the ARRAY constructor. Associative arrays are single-dimensional, unbounded, sparse collections of homogeneous elements.
