PL/SQL Syntax

function Parameters  
  (p_string in varchar2, 
   p_numvalues in number,
   p_separator in varchar2) return t_parameters;

Description

Parses a string of text that contains the specified number of parameters delimited by the specified separator. Parameters() returns the parsed parameters in a varray using the T_PARAMETERS composite datatype, which is defined in the WF_EVENT_FUNCTIONS_PKG package. The following table describes the T_PARAMETERS datatype:

T_PARAMETERS Datatype

Datatype Name Element Datatype Definition
T_PARAMETERS VARCHAR2(240)

Parameters() is a generic utility that you can call in generate functions when the event key is a concatenation of values separated by a known character. Use this function to separate the event key into its component values.

Arguments (input)

p_string A text string containing concatenated parameters.
p_numvalues The number of parameters contained in the string.
p_separator The separator used to delimit the parameters in the string.

Sample Code

Example

set serveroutput on

declare
l_parameters wf_event_functions_pkg.t_parameters;
begin
-- Initialize the datatype
l_parameters := wf_event_functions_pkg.t_parameters(1,2); 

l_parameters := wf_event_functions_pkg.parameters('1111/2222',2,'/');
dbms_output.put_line('Value 1:'||l_parameters(1));
dbms_output.put_line('Value 2:'||l_parameters(2));
end;
