TACRQuery.Params

Contains the parameters for a query's SQL statement.

property Params[Index: Word]: TParams;

Description
Access Params at runtime to view and set parameter names, values, and data types dynamically (at design time use the collection editor for the Params property to set parameter information). Params is a zero-based array of TParams parameter records. Index specifies the array element to access.

Note:   An easier way to set and retrieve parameter values when the name of each parameter is known is to call ParamByName. ParamByName cannot, however, be used to change a parameter's data type or name.

Parameters used in SELECT statements cannot be NULL, but they can be NULL for UPDATE and INSERT statements.
