-Understanding Oracle
-
-It's a bit different than the other RDBMS databases and I'll just try to
-hightlight a few of the important ones the dialect has to deal with:
-
-1. Oracle upper cases all non-quoted identifiers. That means the dialect
-has to decide what to do:
-	1. quote all identifiers which would require developers to quote every
-		identifer they passed in a string to gorm.
-	2. only quote identifers that conflict with reserved words and leave all
-		other identifiers unquoted, which means Oracle will automatically
-		upper case them.  This would allow developers to pass unquoted
-		identifiers in strings they passed to gorm and make the experience
-		align better with the other dialects.
-We chose option #2.
-
-This design decision has the following side affects:
-	a. you must be case insensitive when matching column names, like in
-		the Scope.scan function
-	b. Devs will have to escape reserved words when they reference them
-		in things like: First(&CreditCard{}, `"number" = ?`)
-
-
-2. Oracle handles last inserted id a bit differently, and requires a sql.Out
-parameter to return the value in the oci8 driver.  Since Oracle parameters
-are positional, you need to know how many other bind variables there are before
-adding the returning clause.  We've implemented the
-OraDialect.CreateWithReturningInto(*Scope) to handle this.
-
-3. Oracle doesn't let you specify "AS <tablename> " when selecting a count
-	from a dynamic table, so you just omit it. (see Scope.count() )
-
-4. Oracle handles foreign keys a bit differently:
-	A. REFERENCES is implicit
-	B. ON UPDATE is not supported
-	(see scope.addForeignKey() )
-
-5. Searching a blob requires using a function from the dbms_lob package like
-	instr() and specifying the offset and number of matches.
-	(see oci8.SearchBlob() )
-
-6 Trailing semicolons are not allowed at the end of Oracle sql statements
-	(so they were removed in the unit tests)
