Interface SQLConditionStep<NEXT>

Type Parameters:
NEXT - the stage returned when another complete condition is appended
All Known Subinterfaces:
SQLDeleteWhereStep, SQLSelectHavingStep, SQLSelectWhereStep, SQLUpdateWhereStep
public interface SQLConditionStep<NEXT>
A condition clause that accepts additional comparisons or complete reusable conditions. Simple fluent connector chains follow SQL precedence (AND before OR), so call order does not imply left-associative grouping. Compose a complete SQLCondition with SQLCondition.and(SQLCondition) and SQLCondition.or(SQLCondition) when explicit nesting is required; the compiler adds parentheses for the structured condition tree.

    • or

      SQLComparisonStep<NEXT> or(SQLExpression left)
