问题 I am wondering about this case with Oracle 12c; Table X has column A, with default value 'default' and NOT NULL modifier I insert a new row into Table X, and column A has value 'not-default' I wish to update column A of the above row to the default value of the given column, namely 'default' Is there a short way of doing this without knowing the default value? Can I do something like; UPDATE X SET A = DEFAULT_VAL(A) WHERE ... Trying to update to null obviously triggers a ORA-01407: cannot

问题 This post is similar to link But I do not find answer. I am migrating from Oracle 11g to Oracle 12c. Can I use the same dialect available with hibernate 3.3.0 org.hibernate.dialect.OracleDialect . Also I am using ojdbc14.jar which is JDBC driver version 10.2.0.3.0. And as per Oracle I need to use atleast ojdbc6.jar or minimum JDBC driver version 11.1.0.x.

问题 I have a table with a column to , from and ID . I need to select only rows with every 10th ID which is from A to B . 回答1: select * from (select * from table where from = 'A' and to ='B' order by ID) where mod(rownum/10,1) = 0 It first takes only those from 'A' to 'B', then giving them rownums, and selecting only those in the 10th 20th ETC places.. 回答2: Or you can just use select from, to, id from table1 where id like'%0' and from ='A' and to = 'B' 来源： https://stackoverflow.com/questions

问题 According to Oracle documentation for the remainder(n2,n1) function (https://docs.oracle.com/cd/B19306_01/server.102/b14200/functions133.htm), the remainder(n2,n1) function evaluates to = n2 - n1 * N where N = ROUND(n2/n1) and n1 != 0. So, I would expect remainder(10,4) to return -2 using the above documented method of calculating the remainder as shown below: REMAINDER(10,4) =10 - 4 * N where N = ROUND(10/4) =10 - 4 * 3 since ROUND(10/4) = 3 =10 - 12 =-2 However, running remainder(10,4) in

问题 I'm creating a USER on Oracle 12 c database, using TOAD . After creating the TABLESPACE , I'm creating the USER . I'm a little confusing about the many ROLES and PRIVILEGES that can be given to a USER.

Thank you 回答1: It depends on what operations are you going to perform. If you want to work
