Service Builder: Update data if exist, insert if not exist

[SHI HONG CHIN, modificado hace 7 años.]

I am using Service Builder. My Liferay version is 6.2.

Assume that there is an entity "ABC" with a primary key.

Assume that I use the following codes to do update or insert (Someone call it "UPSERT"):

ABC abc;
try{
	//Get ABC by using primary key value, and then update a column value.
	abc = ABCLocalServiceUtil.getABC(primarykeyvalue);
	abc.setCol1("value");
	ABCLocalServiceUtil.updateABC(abc);
} catch (NoSuchABCException e){
	// If the primary key value not exist in the database table, insert it.
	abc = ABCLocalServiceUtil.createABC(primarykeyvalue);
	abc.setCol1("value");
	ABCLocalServiceUtil.addABC(abc);
}

The exception class and all functions in the above sample code are generated by service builder.

The update and insert operation was success, even when the primary key value not exist in the database table. However, if the primary key value does not exist, there is a warning message "No ABC exists with primary key ....." on server.

I don't want the server to log or display the warning message above. So, what is your recommendation? I am willing to edit my source code.

Use fetchABC method instead of getABC, and check if abc object is null or not. If it is null, it doesn't exist.
