RC Function

Action

Gets the return code of the most recent ODBC function call associated with a cursor. If this function returns zero, the most recent SQL command or fetch statement was executed successfully; otherwise, rc returns a nonzero value.

注: This function only works with Silk Performer's high-level database access interface. If you use it with the medium- or native-level interface, the return value of the rc-function will be undefined.

Syntax

rc( in cCursor : cursor ):number;

Return value

zero if the most recent SQL command or fetch statement was executed successfully, otherwise the return code of the most recent ODBC function call.

Parameter	Description
cCursor	Cursor with which the function call is associated

Example

    write("return code: ");
    write (rc(c1));
  end TMain;

dclsql
