我想通过hibernate执行本机SQL查询:
dbs.createSQLQuery("UPDATE USERS SET :balanceType = :newBalance WHERE UKEY = :ukey")
.setString("balanceType", type.toString())
.setBigDecimal("newBalance", newBalance)
.setLong("ukey", uKey).executeUpdate();
由于:balanceType绑定而失败。
我得到例外:
org.hibernate.exception.SQLGrammarException: could not execute native bulk manipulation query
org.hibernate.exception.SQLGrammarException: could not execute native bulk manipulation query
java.sql.SQLException: ORA-01747: invalid user.table.column, table.column, or column specification
org.hibernate.exception.NestableDelegate@431d9f05
could not execute native bulk manipulation query
UPDATE USERS SET :balanceType = :newBalance WHERE UKEY = :ukey
java.sql.SQLException: ORA-01747: invalid user.table.column, table.column, or column specification
如果我使用String.format在字符串中嵌入paraneters,那么它可以正常工作!
知道我的语法有什么问题吗?
谢谢!

balanceType
不是参数,因此您无法绑定它,您需要使用字符串连接来连接列名。
dbs.createSQLQuery("UPDATE USERS SET " + type.toString() + " = :newBalance WHERE UKEY = :ukey")
.setBigDecimal("newBalance", newBalance)
.setLong("ukey", uKey).executeUpdate();
