In DB2 for os390 this syntax (the INCLUDE keyword) is not allowed, so I am creating the indexes as follows create unique index I_0004 on TABLENAME (a); create index I_0005 on TABLENAME (a, b, c, d); Are the two statements above equivalent to the solution with the INCLUDE keyword? index columns

@JdbcInsert insert multiple entries

由 可紊 提交于 2020-01-14 05:58:06
问题 I'm trying to insert an entry into my DB2 db by using JavaScript @JdbcInsert method. And it works perfect. var myData={ DOCTYPE: "type", DOCID: 1, DOCNAME: "name" } @JdbcInsert("db2", "MYTABLE", myData); What I need is to insert multiple entries at a time.. So I need to change myData object somehow.. But how should I do that.. Assume I need something like var myData={{ DOCTYPE: "type", DOCID: 1, DOCNAME: "name1" },{ DOCTYPE: "type", DOCID: 1, DOCNAME: "name2" }} but it doesn't really work..
