#IBMiSample QSQGNDDL API generates the SQL data definition language statements from a database object. Here's how to use it. How to get SQL CREATE TABLE specification from DDS

#IBMiSample In this example, the  OTDTP0  field is numeric 6 with 0 decimal places. It should contain a number rapresenting a DATE in yymmdd (i.e 210208 - February 8, 2021) or ddmmyy format  (i.e 080221 - February 8, 2021). The following instructions turns yymmdd to ddmmyy or viceversa (the other way around). OTDTP0 zoned(6); OTDTP0 = %dec(%char(%date(OTDTP0:*ymd):*dmy0):6:0); // yymmdd to ddmmyy OTDTP0 = %dec(%date(OTDTP0:*ymd):*dmy);  // yymmdd to ddmmyy I appreciate all the comments made on this blog.
