This is because ownership chaining bypasses permissions checks on referenced objects when they are owned by the principal that owns the objects that refer to them.
Expression you want to evaluate. Value or expression returned if expr is True. Value or expression returned if expr is False. Remarks IIf always evaluates both truepart and falsepart, even though it returns only one of them. Because of this, you should watch for undesirable side effects.
For example, if evaluating falsepart results in a division by zero error, an error occurs even if expr is True. In a form, you want to denote whether Italian is the first language of the contact. You can add a control and use IIf in its Control Source property, like so: You can also "nest" IIf expressions, allowing you to evaluate a series of dependent expressions.
To continue with the preceding example, you might want to test for several different CountryRegion values, and then display the appropriate language depending on which value exists: Since each nested IIf function is the falsepart argument of the IIf function that contains it, the text "Some other language" is only returned if all the expr arguments of all the IIf functions evaluate to False.
For another example, suppose you work at a library.
The library database has a table named Check Outs that contains a field, named Due Date, that contains the date a particular book is due back. To use logical operators such as "And" or "Or" in the expr argument of the IIf function, you must enclose the logical expression in the Eval function.
See the example table that follows. The syntax is the same, with the exception that in a query, you must preface the expression with a field alias and a colon: To use the preceding example, you would type the following in the Field row of the query design grid: For more information about creating queries and calculated fields, see the article Create a simple select query.
For more information about working with VBA, select Developer Reference in the drop-down list next to Search and enter one or more terms in the search box. This example uses the IIf function to evaluate the TestMe parameter of the CheckIt procedure and returns the word "Large" if the amount is greater than ; otherwise, it returns the word "Small".The preceding example uses the IIf function to evaluate the givven expression and returns the word "Expensive" if the amount is greater than ; otherwise, it returns the word "Cheap".
SQL query You can also use the iif function in a query. What is the best way to only grant read write access to one table. Is there a way to do it without having to deny access to all other tables. Jul 17, · Welcome to the benjaminpohle.com Forums.

Feb 12, · "iif" Statement in an SQL Query - Access I have a query that worked using the "Switch" option in the Pivot Statement. I needed to ensure that if in some instances there was no data available in a given Selection of records for one of the fields the Pivot would create, that the query not crash but return a null or "0" value in that field.
SQL Server ensures that only principals that have been granted permission can access objects. When multiple database objects access each other, the sequence is known as a chain.
When SQL Server is traversing the links in the chain, it evaluates permissions differently than it would if .
