Causes Microsoft SQL Server to follow the SQL-92 rules regarding quotation mark delimiting identifiers and literal strings.

Class

TCustomMSConnectionOptions

Syntax

property QuotedIdentifier: boolean default True;

Remarks

Causes Microsoft SQL Server to follow the SQL-92 rules regarding quotation mark delimiting identifiers and literal strings. Identifiers delimited by double quotation marks can be either Transact-SQL reserved keywords or can contain characters not usually allowed by the Transact-SQL syntax rules for identifiers.

True (the default value):

Identifiers can be delimited by double quotation marks, and literals must be delimited by single quotation marks.

All strings delimited by double quotation marks are interpreted as object identifiers. Therefore, quoted identifiers do not have to follow the Transact-SQL rules for identifiers. They can be reserved keywords and can include characters not always allowed in the Transact-SQL identifiers. Double quotation marks cannot be used to delimit literal string expressions; single quotation marks must be used to enclose literal strings. If a single quotation mark (') is a part of the literal string, it can be represented by two single quotation marks ("). QuotedIdentifier must be True when reserved keywords are used for object names in the database.

False (BDE compatibility):

Identifiers cannot be quoted and must follow all Transact-SQL rules for identifiers. Literals can be delimited by either single or double quotation marks. If a literal string is delimited by double quotation marks, the string can contain embedded single quotation marks such as apostrophes.

QuotedIdentifier must be True when creating or manipulating indexes on computed columns or indexed views. If QuotedIdentifier is False, CREATE, UPDATE, INSERT, and DELETE statements on tables with indexes on computed columns or indexed views will fail.
