=== Test for NULL === | |||
In order to be able to test for a NULL value in a set of results from a query, you need to compare against a specific DB NULL value. Otherwise you'll get an error similar to... | |||
<code> Error: "Cannot convert the "0" value of type "System.Int32" to type "System.DBNull" </code> | |||
So to correctly test, use the following... | |||
<source lang="powershell"> | |||
if ([System.DBNull]::Value.Equals($db_query_result)) { | |||
Write-Host "Result is NULL" | |||
} | |||
</source> | |||
