Valore proprietà

Tipo: System.String
A String value that specifies the actual text of the Transact-SQL statement that defines the check constraint. By default, the value is unspecified.

Osservazioni

The Text property of the Check object is equivalent to the Transact-SQL check clause in the definition of Vincoli CHECK, which specifies the actual text of the Transact-SQL definition statement.

In Transact-SQL the check constraint is defined by the statement such as:

ALTER TABLE CheckTbl

ADD CONSTRAINT chkRowCount CHECK (CheckFnctn() > 1 )

GO

In SMO, the Text property requires only the check clause:
