2  Arguments
 

3  DEFAULT_default-value

   Provides a default value to be used if the user presses the
   Return key. The default value must be a correctly formatted
   character string that can be converted to the data type of the
   variable.
 

3  HIDE

   Disables echo of the input text. The default is to echo all input
   characters.
 

3  PROMPT_string-literal

   Provides a prompt string that is displayed before accepting
   input.
 

3  NOPROMPT

   Disables prompting with a string.
 

3  TIMEOUT_numeric-literal

   If the user does not respond within this many seconds, then an
   error is returned. Negative or zero values of the numeric-literal
   are ignored. The default is to wait indefinitely.
 

3  UPPER

   All lowercase characters are converted to uppercase before
   assignment to the variable. The default is to leave lowercase
   characters unchanged.
 

3  variable-ref

   An interactive SQL variable defined using the DECLARE Variable
   statement.
 

2  Examples
   Example 1: Prompting Based on the PROMPT and NOPROMPT Clauses

   SQL> DECLARE :x INTEGER;
   SQL> DECLARE :y INTEGER;
   SQL>
   SQL> ACCEPT :x indicator :y PROMPT 'what value? ';
   what value? 10
   SQL> PRINT :x, :y;
              X             Y
             10             0
   SQL>
   SQL> ACCEPT :x INDICATOR :y NOPROMPT;
   11
   SQL> PRINT :x, :y;
              X             Y
             11             0
   SQL>
   SQL> ACCEPT :x;
   Enter value for X: 12
   SQL> PRINT :x;
              X
             12
   SQL>

   Example 2: Using ACCEPT to Prompt for SET FLAGS String

   This sequence would be included in a script.

   SQL> DECLARE :debug_flags CHAR(20);
   SQL> ACCEPT :debug_flags;
   Enter value for DEBUG_FLAGS: trace
   SQL> PRINT :debug_flags;
    DEBUG_FLAGS
    trace
   SQL> SET FLAGS :debug_flags;
   SQL> SHOW FLAGS
