Lookups that are not plain binary comparisons.

Variants

IExact(Value)

Case-insensitive equality.

Contains

Substring match; case_insensitive selects icontains.

Fields

needle: String

Pattern (literal text, not a LIKE pattern; backends escape it).

case_insensitive: bool

Case-insensitive?

StartsWith

Prefix match.

Fields

needle: String

Prefix (literal text).

case_insensitive: bool

Case-insensitive?

EndsWith

Suffix match.

Fields

needle: String

Suffix (literal text).

case_insensitive: bool

Case-insensitive?

Regex(String)

Regex match (capability-gated).

In(Vec<Value>)

Membership in a literal list.

InSubquery(Box<QueryPlan>)

Membership in the single column produced by a subquery.

Range(Value, Value)

Inclusive range lo <= x <= hi.

IsNull(bool)

IS NULL (true) / IS NOT NULL (false).
