Executing Parameterized Queries
Parameterized queries can be reused and mitigate SQL injection attacks. You can execute SELECT Parameterized queries take arrays as input.
Example: Searching Google Campaign Manager
The following example macro executes a parameterized search: When you run the macro, you are prompted to enter a search value.
Sub DoSelectParams()
On Error GoTo Error

module.SetConnectionString ("ProfileID=MyUserProfileID;")
