MySQL REGEXP performs a pattern match of a string expression against a pattern. In terms of syntax structure, it fits into a boolean expression just as an equalssign normally would: Its functionality is similar too, though by default, LIKEwill match English alphabet characters without regard to capitalization (i.e. En d’autres termes, un nœud peut être parcouru un nombre de fois arbitraire dans la même requête.In other words, a node can be traversed an arbitrary number of times in the same query.

SQLite understands the following binary operators, in order fromhighest to lowest precedence: Supported unary prefix operators are these: The COLLATE operator is a unary postfixoperator that assigns a collating sequence to an expression.The COLLATE operator has a higher precedence (binds more tightly) than anybinary operator and any unary prefix operator except "~". – CoDe Jul 30 '17 at 10:26 101. The arbitrary length pattern takes regular expression style pattern quantifiers in order to specify the number of times a given search pattern is repeated. La fonction de chemin la plus courte est utilisée pour rechercher le chemin le plus court entre deux nœuds donnés d’un graphique, ou entre un nœud donnée et tous les autres nœuds d’un graphique.Shortest path function is used to find shortest path between two given nodes in a graph or between a given node and all the other nodes in a graph.
