Parses a query and gets all information about it.

public static getAll ( string $query ) : array
$query	string	The query to be parsed.
Résultat	array	The array returned is the one returned by `static::getFlags()`, with the following keys added: - parser - the parser used to analyze the query; - statement - the first statement resulted from parsing; - select_tables - the real name of the tables selected; if there are no table names in the `SELECT` expressions, the table names are fetched from the `FROM` expressions - select_expr - selected expressions

public static getClause ( Statement $statement, TokensList $list, string $clause, integer \| string $type, boolean $skipFirst = true ) : string
$statement	SqlParser\Statement	The parsed query that has to be modified.
$list	SqlParser\TokensList	The list of tokens.
$clause	string	The clause to be returned.
$type	integer \| string	The type of the search. If int, -1 for everything that was before 0 only for the clause 1 for everything after If string, the name of the first clause that should not be included.

$delimiter	string	The delimiter to be used.
Résultat	array	Array containing the first full query, the remaining part of the query and the last delimiter.

Gets an array with flags this statement has.

public static getFlags ( Statement \| null $statement, boolean $all = false ) : array
$statement	SqlParser\Statement \| null	The statement to be processed.
$all	boolean	If `false`, false values will not be included.
Résultat	array

Gets a list of all tables used in this statement.

public static getTables ( Statement $statement ) : array
$statement	SqlParser\Statement	Statement to be scanned.

$statement	SqlParser\Statement	The parsed query that has to be modified.
$list	SqlParser\TokensList	The list of tokens.
$old	string	The type of the clause that should be replaced. This can be an entire clause.
