C# 클래스 Remotion.Linq.SqlBackend.MappingResolution.SqlContextExpressionVisitor

Ensures that a given expression matches SQL server value semantics.

SqlContextExpressionVisitor traverses an expression tree and ensures that the tree fits SQL server requirements for expressions. In scenarios where a value is required as per SQL server standards, boolean expressions are converted to integers using CASE WHEN expressions. In such situations, and constants are converted to 1 and 0 values, and boolean columns are interpreted as integer values. In scenarios where a predicate is required, boolean expressions are constructed by comparing those integer values to 1 and 0 literals. In scenarios where a single value is required, an exception is thrown where compound values (NewExpression) or entities are encountered.
