What does SQL Select symbol - mean? - Stack Overflow

In Oracle, SQLite3, and MySQL, it concatenates strings. Please see the Oracle documentation. The MySQL documentation. Also, it's part of ANSI SQL, but read this for more information. It's a concatenation operator. So you would get 'a,b' from that. I think || will work on most RDBMS's.

<> operator means not equal to in MS SQL. It compares two expressions (a comparison operator).
