The rdatestr() function

The rdatestr() function converts an internal DATE value to a character string.

Syntax

mint rdatestr(jdate, outbuf)
   int4 jdate;
   char *outbuf;
jdate
The internal representation of the date to format.
outbuf
A pointer to the buffer to contain the string for the jdate value.

Usage

For the default locale, U.S. English, the rdatestr() function determines how to interpret the format of the character string with the following precedence:
  1. The format that the DBDATE environment variable specifies (if DBDATE is set)

    For more information, see the HCL OneDB™ Guide to SQL: Reference.

  2. The format that the GL_DATE environment variable specifies (if GL_DATE is set)

    For more information, see the HCL OneDB GLS User's Guide.

  3. The default date form: mm/dd/yyyy

When you use a nondefault locale and do not set the DBDATE or GL_DATE environment variable, rdatestr() uses the date end-user format that the client locale defines. For more information, see the HCL OneDB GLS User's Guide.
