[英]jOOQ insert query with returning generated keys
I installed jOOQ into eclipse, generated classes for my mySQL, but I still have problems to write also some basic queries. 我在jclipse中安装了jOOQ,为mySQL生成了类,但是我仍然有问题要写一些基本的查询。
I tried to compose insert query with returning of generated keys, but compiler throws error 我试图通过返回生成的密钥来组合插入查询,但编译器抛出错误
Table: tblCategory Columns: category_id, parent_id, name, rem, uipos 表:tblCategory列:category_id,parent_id,name,rem,uipos
Result<TblcategoryRecord> result= create.insertInto(Tblcategory.TBLCATEGORY,
Tblcategory.PARENT_ID, Tblcategory.NAME, Tblcategory.REM, Tblcategory.UIPOS)
.values(node.getParentid())
.values(node.getName())
.values(node.getRem())
.values(node.getUipos())
.returning(Tblcategory.CATEGORY_ID)
.fetch();
tried also other differnt ways how to do it right way? 还尝试了其他不同的方法如何正确地做到这一点?
thanks charis 谢谢charis
The syntax you're using is for inserting multiple records. 您正在使用的语法是插入多个记录。 This is going to insert 4 records, each with one field.
这将插入4条记录,每条记录包含一个字段。
.values(node.getParentid())
.values(node.getName())
.values(node.getRem())
.values(node.getUipos())
But you declared 4 fields, so that's not going to work: 但你宣布了4个字段,所以这不会起作用:
create.insertInto(Tblcategory.TBLCATEGORY,
Tblcategory.PARENT_ID, Tblcategory.NAME, Tblcategory.REM, Tblcategory.UIPOS)
What you probably want to do is this: 你可能想做的是:
Result<TblcategoryRecord> result = create
.insertInto(Tblcategory.TBLCATEGORY,
Tblcategory.PARENT_ID, Tblcategory.NAME, Tblcategory.REM, Tblcategory.UIPOS)
.values(node.getParentid(), node.getName(), node.getRem(), node.getUipos())
.returning(Tblcategory.CATEGORY_ID)
.fetch();
Or alternatively: 或者:
Result<TblcategoryRecord> result = create
.insertInto(Tblcategory.TBLCATEGORY)
.set(Tblcategory.PARENT_ID, node.getParentid())
.set(Tblcategory.NAME, node.getName())
.set(Tblcategory.REM, node.getRem())
.set(Tblcategory.UIPOS, node.getUipos())
.returning(Tblcategory.CATEGORY_ID)
.fetch();
Probably, you're even better off by using 也许,通过使用你会更好
TblcategoryRecord result =
// [...]
.fetchOne();

statements that return values: 或者用于创建返回值的

preffered SOLUTION 优先解决方案
try {
TblcategoryRecord record = (TblcategoryRecord) create
.insertInto(Tblcategory.TBLCATEGORY)
.set(Tblcategory.PARENT_ID, node.getParentid())
.set(Tblcategory.NAME, node.getName())
.set(Tblcategory.REM, node.getRem())
.set(Tblcategory.UIPOS, node.getUipos())
.returning(Tblcategory.CATEGORY_ID)
.fetchOne();
node.setId(record.getCategoryId());
} catch (SQLException e1) { }
Try 尝试
YoutableRecord result = create
.insertInto(YOURTABLE)
.set(YOURTABLE.PROD_NAME, "VAL")
.returning(YOURTABLE.ID_PR)
.fetchOne();
int id = result.getValue(Products.PRODUCTS.ID_PR);
