Name

exec_result — Returns a result set row to the calling procedure context

Synopsis

any exec_result ( in res_values_array any );
 

Description

This function returns a result set row to the calling procedure's context, whether it is the client, exec function or a procedure view). The row's values are the elements of the supplied res_values_array vector.

Parameters

res_values_array

This parameter can be one of two things:

a vector of strings (like vector('cola', 'colbb')). When used that way it makes columns named 'cola' and 'colb' with type ANY and precision 256
an array with the same format as the 0th element of the metadata returned by exec() and rexec() , which contains all the type information and can be used directly.

Return Types

The row's values are the elements of the supplied res_values_array vector. For example: exec_result (vector (1, 'a')) will return a row of two columns: 1 and 'a'. This is similar to the result() function, but it uses an array instead of parameter list

Examples

Example 24.103. Result set rows

create procedure XX1 ()
{
  declare meta, _dt any;
  declare inx integer;
  exec ('select U_ID, U_NAME from SYS_USERS', null, null, null, 0, meta, _dt);
  inx := 0;

  exec_result_names (meta[0]);
  while (inx < length (_dt))
    {
      exec_result (_dt[inx]);
      inx := inx + 1;
    }
};
