Firstly, you need init db2 connection before usage.

//db:variable for opening connection  
db2crud.init({db:db2,dbname:'TEST'});

// select * from db2crudtest where ID=2 and STR='str3';
var tbObj = {
  ID : 2,
  STR : "str3"
};
db2crud.get("db2crudtest", tbObj).then(function(rdata) {
  console.log("retdata=" + JSON.stringify(rdata));
})

// delete from db2crudtest where ID=2 and STR='str3'
var tbObj = {
  ID : 2,
  STR : "str3"
};
db2crud.remove("db2crudtest", tbObj).then(function(rdata) {
  console.log("retdata=" + JSON.stringify(rdata));
})

// update db2crudtest set STR='str3' where ID=2
var tbObj = {
  ID : 2,
  STR : "str3"
};
db2crud.update("db2crudtest", tbObj).then(function(rdata) {
  console.log("retdata=" + JSON.stringify(rdata));
})

// insert db2crudtest(ID,STR) VALUES (2,"str2")
tbObj = {
  ID : 2,
  STR : "str2"
};
db2crud.insert("db2crudtest", tbObj).then(function(rdata) {
  console.log("retdata=" + JSON.stringify(rdata));
})

// insert db2crudtest(ID,STR) VALUES (3,"str3")
// insert db2crudtest(ID,STR) VALUES (4,"str4")
tbObj = [{ID:3,STR:"str3"},{ID:4,STR:"str4"}];
dbutils.insert("db2crudtest",tbObj).then(function(rdata){
  console.log("retdata=" + JSON.stringify(rdata));
});

    "field":"STR",
    "value":"123456",
    "errMsg":"length of STR[123456] must be less than 5"
  }
]
tbObj = [{NUM:"2",STR:"2",DATEFIELD:"2017-09-03 05:25:00"}
       ,{NUM:3,STR:3,DATEFIELD:"2017-09-03 05:25:00"}
