Question

org.springframework.jdbc.BadSqlGrammarException： PreparedStatementCallback;糟糕的SQL语法[删除 model_state_history FROM model_state_history INNER JOIN模型ON model_state_history.model_id = model.id WHERE model.package_id =？]; 嵌套异常是org.h2.jdbc.JdbcSQLException：SQL中的语法错误语句“DELETE model_state_history FROM [*] model_state_history INNER JOIN模型ON model_state_history.model_ID = model.ID WHERE model.PACKAGE_ID =？ “; SQL声明：

它会在输出中抛出上述内容。对于我的眼睛，我没有看到语法错误。我正在使用MySQL数据库。上面的SQL语法中有什么明显错误的吗？

使用DELETE FROM语法也会出现语法错误。

org.springframework.jdbc.BadSqlGrammarException： PreparedStatementCallback;糟糕的SQL语法[DELETE FROM model_state_history INNER JOIN模型ON model_state_history.model_id = model.id WHERE model.package_id =？];嵌套异常是 org.h2.jdbc.JdbcSQLException：SQL语句“DELETE中的语法错误 FROM model_STATE_HISTORY INNER [*] JOIN模型ON model_STATE_HISTORY.model_ID = model.ID WHERE model.PACKAGE_ID =？ “; SQL语句：DELETE FROM model_state_history INNER JOIN模型ON model_state_history.model_id = model.id WHERE model.package_id =？ [42000-176]

这是正在运行的代码

  @Transactional
  private int deleteAllModels(Long packageId) throws DataAccessException {
    return new NamedParameterJdbcTemplate(dataSource).update(
        "DELETE FROM model_state_history INNER JOIN model ON model_state_history.version_id = model.id WHERE model.package_id = :package_id",
        ImmutableMap.of("package_id", packageId));

Answer 1

第二个想法，我认为你可能有JOIN语法的问题。你正在写

DELETE FROM ... INNER JOIN ... ON msh.version_id = m.id WHERE m.package_id =：package_id

我认为WHERE应该是AND，所以查询会变成：

"DELETE FROM model_state_history INNER JOIN model 
 ON model_state_history.version_id = model.id AND model.package_id = :package_id"

因为WHERE引用了DELETE语句，该语句中没有model表格＆＃34;范围＆＃34;。

干杯，
