== SQL string concatenation ==
SQL has string concatentation using infix || in the style of PL/1 but does not have variables as such.▼
▲SQL has string
<lang sql>create table foo ( a varchar(10),b varchar(10));
Line 7 ⟶ 9:
::<code>select into</code> seems to be a non-standard extension to sql which is mostly used for creating backups of data in existing tables. Here, though, we have three lines -- the first two lines are analogous to variable declaration and variable assignment, and the last line illustrates the task requirement. That said, note that this || mechanism is the ansi standard way to concatenate string (introduced in sql-92) and some implementations of sql (such as mysql) [http://troels.arvin.dk/db/rdbms/#functions-concat do not support this syntax]. --[[User:Rdm|Rdm]] 19:28, 16 November 2010 (UTC)
::: Stick with the ANSI standard; the deviants can have their own entries (or at least their own sub-solution). –[[User:Dkf|Donal Fellows]] 23:40, 16 November 2010 (UTC)
