19.5.8 a_rdb_CNV_DATEchar() (convert DATE-type data)

(1) Function

This CLI function converts SQL DATE-type data to character string data in C or C++. The following figure shows an example of conversion from DATE-type data to character string data.

Figure 19‒8: Example of conversion from DATE-type data to character string data

Explanation:

• This example converts DATE-type data to character string data according to the predefined output representation that represents a date. For details about the predefined output representation for dates, see the topic Predefined character-string representations in the manual HADB SQL Reference.

• Null characters (0x00) are added at the end.
