유형: System.String
A String value that specifies the string to be parsed.

유형: Microsoft.SqlServer.Management.Dmf.ExpressionNode
An ExpressionNode object value that specifies part of an expression.
주의
Depending on the type of expression the object assigns the appropriate type when parsing. For example, the ExecuteSql statement specifies a function. If the expression contains a function then the Type property is set to Function.
The expression must conform to the Transact-SQL expression syntax:
property comparison_operator constantList
where
property: one of the facet properties
comparison_operator: = != > >= < <= [NOT]LIKE [NOT]IN
constantList: constant [, constantList]
[!참고]
The Like operator uses the Transact-SQL syntax.
The expression can be extended using logical operators:
condition_expression logical_operator condition_expression
where
logical_operator: AND OR
예
C#
string expressionStr = "ExecuteSql('Numeric','SELECT 1')";
ExpressionNode node = ExpressionNode.Parse (expressionStr);
TestAssertion.IsTrue (node.Type == ExpressionNodeType.Function, "Should be function");
