Параметры

Возвращаемое значение

Тип: Microsoft.SqlServer.Management.Dmf. . :: . .ExpressionNode
An ExpressionNode object value that specifies part of an expression.

Замечания

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]

ПримечаниеПримечание

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

Примеры

C#

string expressionStr = "ExecuteSql('Numeric','SELECT 1')";
ExpressionNode node = ExpressionNode.Parse (expressionStr);
TestAssertion.IsTrue (node.Type == ExpressionNodeType.Function, "Should be function");
