Structure
SQLList
A fundamental syntactical expression - a list of subexpresions with a specified “separator” subexpression.
struct SQLListOverview
When serialized, an empty SQLList outputs nothing, a single-item SQLList outputs the serialization of that one expression, and all other SQLLists output the entire list of subexpressions joined by an appropriate number of copies of the separator subexpression. The default separator is SQLRaw(", ").
Examples:
print(database.serialize(SQLList(SQLLiteral.string("a"), SQLLiteral.string("b"))).sql)
// "'a', 'b'"
print(database.serialize(SQLList(SQLLiteral.string("a"), SQLLiteral.string("b"), separator: SQLBinaryOperator.and)).sql)
// "'a'AND'b'"
print(database.serialize(SQLList(SQLLiteral.string("a"), SQLLiteral.string("b"), separator: SQLRaw(" AND ")).sql)
// "'a' AND 'b'"Topics
Initializers
init([any SQLExpression], separator: any SQLExpression)Create a list from a list of expressions and an optional separator expression.
Instance Properties
var expressions: [any SQLExpression]The list of subexpressions to join.var separator: any SQLExpressionThe expression with which to join the list of subexpressions.
Instance Methods
func serialize(to: inout SQLSerializer)Invoked when a request is made to serialize the expression to raw SQL.
