TPgParam Class

A class that is used to set the values of individual parameters passed with queries or stored procedures.

For a list of all members of this type, see TPgParam members.




TPgParam = class(TDAParam);


Use the properties of TPgParam to set the value of a parameter. Objects that use parameters create TPgParam objects to represent these parameters. For example, TPgParam objects are used by TPgSQL, TCustomPgDataSet.

TPgParam shares many properties with TField, as both describe the value of a field in a dataset. However, a TField object has several properties to describe the field binding, and how the field is displayed, edited, or calculated that are not needed in a TPgParam object. Conversely, TPgParam includes properties that indicate how the field value is passed as a parameter.
