DESCRIPTION:

 

 

The ADOParameter objects represent parameters associated with parameterized queries, or the in/out arguments and the return values of stored procedures.

 

 

 

 

 

 

Many providers support parameterized commands.

 

 

 

These are commands in which the desired action is defined once, but variables (or parameters) are used to alter some details of the command.

 

 

For example, an SQL SELECT statement could use a parameter to define the matching criteria of a WHERE clause, and another to define the column name for a SORT BY clause.
