The rdefmtdate() function

Syntax

mint rdefmtdate(jdate, fmtstring, inbuf)
   int4 *jdate;
   char *fmtstring;
   char *inbuf;

jdate

A pointer to an int4 variable that receives the internal DATE value for the inbuf string.

fmtstring

A pointer to a buffer that contains the formatting mask to use for the inbuf string.

inbuf

A pointer to the buffer that contains the date string to convert.

Usage

The fmtstring argument of the rdefmtdate() function points to the date-formatting mask, which contains formats that describe how to interpret the date string.

The input string and the fmtstring must be in the same sequential order in terms of month, day, and year. They need not, however, contain the same literals or the same representation for month, day, and year.

You can include the weekday format (ww), in fmtstring, but the database server ignores that format. Nothing from the inbuf corresponds to the weekday format.

If the value stored in inbuf is a four-digit year, the rdefmtdate() function uses that value. If the value stored in inbuf is a two-digit year, the rdefmtdate() function uses the value of the DBCENTURY environment variable to determine which century to use. If you do not set DBCENTURY, the DataBlade® API uses the current century. For information about how to set DBCENTURY, see the HCL OneDB™ Guide to SQL: Reference.
