php_odbc_connstr_estimate_quote_length()

php_odbc_connstr_is_quoted()

PHPAPI bool php_odbc_connstr_is_quoted

(

const char *

str

)

Determines if a string matches the ODBC quoting rules.

A valid quoted string begins with a '{', ends with a '}', and has no '}' inside of the string that aren't repeated (as to be escaped).

These rules are what .NET also follows.

php_odbc_connstr_quote()

PHPAPI size_t php_odbc_connstr_quote	(	char *	out_str,
		const char *	in_str,
		size_t	out_str_size )

Quotes a string with ODBC rules.

Some characters (curly braces, semicolons) are special and must be quoted. In the case of '}' in a quoted string, they must be escaped SQL style; that is, repeated.

php_odbc_connstr_should_quote()

PHPAPI bool php_odbc_connstr_should_quote

(

const char *

str

)

Determines if a value for a connection string should be quoted.

The ODBC specification mentions: "Because of connection string and initialization file grammar, keywords and attribute values that contain the characters []{}(),;?*=!@ not enclosed with braces should be avoided."

Note that it assumes that the string is not already quoted. You should check beforehand.
