A variable in a SQL statement that must be replaced with a valid value or address of a value in order for the statement to execute successfully. WebDB component developers typically use bind variables to display a parameter entry field in a component's parameter entry form. The entry field allows end users to choose the data that the component will display.
A bind variable is a place-holder variable in a SQL statement that must be replaced with a valid value (or address of a value) before the statement can successfully execute. For example, "DELETE FROM EMPLOYEES WHERE EMPNO = :EMPNO_BIND_VAR".
