insertable g string

Turn from:insertable = false, updatable = False useWhen using JPA to configure an entity, if there are two attributes (one is a generic attribute and one is a many-to-one property), the error will be indicated when mapping to the same column in the database.At this point, add insertable = False, updatable = False, in the @joincolumn annotation of the many-to-one to resolve.For example:/*** User Class*/@Entity @Table (name= "Tbl_sys_user") Public cla

for insert , but is okay for update , delete . As of MySQL 5.7.11, that's still true for nondependent subqueries . For dependent subqueries of the select list, no data change Statements are permitted. Certain joins (see additional join discussion later in this section) Reference to Nonupdatable view in the FROM clause Subquery in the WHERE clause, refers to a table in the FROM clause Refers literal values (in this case, there was no underlying table to update) ALGORITHM = TEMPTABLE

Idea: it is actually matching one by one. There are no highlights in the solution, and I don't want to say anything. Of course, you can also embed IsMatch into StrStr to reduce the overhead of function calling, but the readability may be reduced. 1.
