Configuring Parameter Associations SECTION 12 Databases
191
Parameter associations provide a means of supplying values to parameters
whenever a Server Query is run. Each required parameter defined within the
query is associated with a point or constant value. At the time the Query is run,
the current value of the point (or the constant value) is passed to the query.
Under the Development Environment the points default value is used.
Parameter Associations are added by right-clicking the Recordset and
selecting 'Add Parameter…' from the popup menu. The following dialog box is
shown:
12-5-1 Name
A unique Parameter Association name will be automatically provided. This can
be modified to provide a more meaningful name if required. By convention,
this is made the same as the name of the parameter defined within the
database but this is not essential.
12-5-2 Index
The index is used to determine which parameter in the Query to associate the
value with. The index is automatically incremented for each parameter that is
added to the Recordset.
12-5-3 Data Type
The Data Type list will be populated with a selection of available data types.
The correct data type for the parameter being configured must be selected,
otherwise the Recordset will fail to open.
12-5-4 Use point to hold parameter value
When unchecked, the constant Value specified is passed as the parameter to
the query. When checked, the current value of the point is passed as the
parameter.
12-5-5 Point
The name of the point to be used. The Browse button may be used to select a
current point, or add a new one.
12-5-6 Value
The constant value to be used.
