Identifiers are used to refer to objects exposed by the driver, such as tables, columns, or caches. The driver supports both unquoted and quoted identifiers for naming objects. An unquoted identifier must start with an ASCII alpha character and can be followed by zero or more ASCII alpha or numeric characters. Unquoted identifiers are converted to uppercase before being used.
Quoted identifiers must be enclosed in double quotation marks (""). A quoted identifier can contain any Unicode character, including the space character, and is case-sensitive. The Oracle Service Cloud driver recognizes the Unicode escape sequence \uxxxx as a Unicode character. You can specify a double quotation mark in a quoted identifier by escaping it with a double quotation mark.
The maximum length of both quoted and unquoted identifiers is 128 characters.
Note: When object names are passed as arguments to catalog functions, the case of the value must match the case of the name in the database. If an unquoted identifier name was used when the object was created, the value passed to the catalog function must be uppercase because unquoted identifiers are converted to uppercase before being used. If a quoted identifier name was used when the object was created, the value passed to the catalog function must match the case of the name as it was defined. Object names in results returned from catalog functions are returned in the case that they are stored in the database.
