Expressions — AQL

Expressions

• Operators — comparison / logical operators, is null, and combining conditions.
• Literals — string, number, boolean, and null literals.
• Path Expressions — .field paths and link traversal.
• Casts & Types — <Type> casts and computed-field type resolution.

Global references

global <name> reads a declared global variable — the current user, active tenant, etc. It’s an operand like a path or literal, so it works anywhere an expression does (a filter, a computed field, an RLS policy predicate):

multi select Doc { id, title } filter .owner = global current_user;

It lowers to a read of the backing session setting, current_setting('app.<name>', …). See Globals for declaration and how the value is set from the client.
