QxSql Namespace Reference

The QxSql namespace contains several utilities that are specific to the SQL module and grouped together for better organization and encapsulation when making use of using directives.

Classes
class	ConcreteInline
	The ConcreteInline class is used to implement each specific inline keyword. More...
class	Inline
	The Inline class is the base class from which all SQL inline keywords derive from. More...

Concepts
concept	sql_struct_inside
	Specifies that a type is a SQL-tied struct registered with QX_SQL_STRUCT().
concept	sql_struct_outside
	Specifies that a type is a SQL-tied struct registered with QX_SQL_STRUCT_OUTSIDE().
concept	sql_struct
	Specifies that a type is a SQL-tied struct.
concept	sql_convertible
	Specifies that a type is generally convertible to/from SQL.
concept	sql_override_convertible
	Specifies that a type has override conversions for changing to/from SQL.
concept	sql_keyable
	Specifies that a type has a known method for creating a corresponding key.
concept	sql_collective
	Specifies that a type is a non-associative container, the value type of which is convertible to/from SQL.
concept	sql_associative
	Specifies that a type is an associative container, the value type of which is convertible, to/from SQL, and for which a key/value type specializaton of keygen() exists.
concept	sql_containing
	Specifies that a type is a container, and abides by the other corresponding restrictions for that kind of a container.
concept	sql_optional
	Specifies that a type is a specialization of std::optional that manages values of a SQL convertible type.

Function Documentation

operator!()

Qx::SqlString QxSql::operator! ( const Inline & i )

inline

Returns a string of "NOT i".

operator""_sq()

Qx::SqlString QxSql::operator""_sq ( const char16_t * str, size_t size )

inlinenoexcept

Creates a regular SQL string.

operator""_sqi()

Qx::SqlString QxSql::operator""_sqi ( const char16_t * str, size_t size )

inlinenoexcept

Creates an SQL identifier string; that is, the original string is automatically double-quoted.

operator""_sqs()

Qx::SqlString QxSql::operator""_sqs ( const char16_t * str, size_t size )

inlinenoexcept

Creates an SQL string literal string; that is, the original string is automatically single-quoted.

operator&=()

Qx::SqlString QxSql::operator&= ( const Inline & a, const Inline & b )

inline

Returns the concatenation of and b.

This is the same as operator+() for normal strings.

operator|=()

Qx::SqlString QxSql::operator|= ( const Inline & a, const Inline & b )

inline

Returns the concatenation of a and b with a space between.

sq()

Qx::SqlString QxSql::sq ( const QString & s )

inlinenoexcept

Creates an SQL identifier string from s; that is, the original string is automatically double-quoted.

There is generally no need to use this over the QString constructors or literal operators, other than consistency.

sqi()

Qx::SqlString QxSql::sqi ( const QString & s )

inlinenoexcept

Creates an SQL identifier string from s; that is, the original string is automatically double-quoted.

sqs()

Qx::SqlString QxSql::sqs ( const QString & s )

inlinenoexcept

Creates an SQL string literal string from s; that is, the original string is automatically single-quoted.
