CaseBuilder

class CaseBuilder<DB, TB extends keyof DB, W = unknown, O = never> implements Whenable<DB, TB, W, O> {

constructor(props: CaseBuilderProps);

when<RE extends ReferenceExpression<DB, TB>, VE extends OperandValueExpressionOrList<DB, TB, RE>>(

lhs: unknown extends W ? RE : KyselyTypeError<"when(lhs, op, rhs) is not supported when using case(value)">,

rhs: VE,

when(expression: Expression<W>): CaseThenBuilder<DB, TB, W, O>;

when(value: unknown extends W ? KyselyTypeError<"when(value) is only supported when using case(value)"> : W): CaseThenBuilder<DB, TB, W, O>;

}

§Type Parameters

TB extends keyof DB

W = unknown

O = never

Whenable<DB, TB, W, O>

new CaseBuilder(props: CaseBuilderProps)

when<RE extends ReferenceExpression<DB, TB>, VE extends OperandValueExpressionOrList<DB, TB, RE>>(lhs: unknown extends W ? RE : KyselyTypeError<"when(lhs, op, rhs) is not supported when using case(value)">, op: ComparisonOperatorExpression, rhs: VE): CaseThenBuilder<DB, TB, W, O>

Adds a when clause to the case statement.

A when call must be followed by a CaseThenBuilder.then call.

when(expression: Expression<W>): CaseThenBuilder<DB, TB, W, O>

when(value: unknown extends W ? KyselyTypeError<"when(value) is only supported when using case(value)"> : W): CaseThenBuilder<DB, TB, W, O>
