Function Documentation

checkName()

void tinysql::anonymous_namespace{Session.cpp}::checkName	(	std::string_view	name,
		std::string_view	what
	)

Checks a new table or column name.

Parameters

name	The name.
what	"table" or "column", for the error message.

Exceptions

SqlError

Unless the name starts with a letter, has only letters, digits, _ and -, and is at most kMaxNameLength characters long.

fitted()

ResultSet tinysql::anonymous_namespace{Session.cpp}::fitted	(	std::vector< std::string >	headers,
		std::vector< std::vector< std::string > >	rows
	)

Builds a result whose column widths fit the headers and the values (used by DESCRIBE).

Parameters

headers	The column titles.
rows	The values, one inner vector per row.

Returns

The result set.

Definition at line 54 of file Session.cpp.

matches()

bool tinysql::anonymous_namespace{Session.cpp}::matches	(	std::string_view	fieldValue,
		const Condition &	condition
	)

Applies a WHERE test to one value.

Parameters

fieldValue	The row's value in the tested column.
condition	The test.

Returns

True if the value passes. LIKE matches a pattern, ignoring case (see matchesLike()). The other operators compare numbers as numbers when both sides are integers, otherwise as case-sensitive text.

plural()

std::string tinysql::anonymous_namespace{Session.cpp}::plural	(	std::size_t	n,
		std::string_view	word
	)

Writes a count with a noun in singular or plural.

Parameters

n	The count.
word	The noun in singular, e.g. "row".

Returns

E.g. "1 row" or "3 rows".
