Methods

Build(ITranslationContext, MethodCallExpression, bool)

Builds the aggregate translation. isExpression tells the builder whether the surrounding visitor is in Expression mode (lenient, partial-translation OK) or strict-Sql mode. Combined with IsServerSideOnly on the per-aggregate config: when both !IsServerSideOnly and isExpression hold, a translation failure of any argument / item / value expression makes Build return null (so the dispatch chain can cascade to the partial-translation fallback). Otherwise, failures bubble as SqlErrorExpression the same way as before.

public Expression? Build(ITranslationContext ctx, MethodCallExpression functionCall, bool isExpression = false)

Parameters

ctx ITranslationContext

functionCall MethodCallExpression

isExpression bool

Returns

Expression
