Question

当我运行'sqlFile'类型的Liquibase changeSet来插入数据时，我得到一个MySQLSyntaxErrorException。我的查询是正确的，因为它可以在MySQL工作台中正常运行。

这是我的Liquibase changeSet：

INSERT INTO table1 (table1col1, table1col2)
VALUES ('table1col1value', 'table1col2value')
;

-- link to the latest value of table1
INSERT INTO table2 (table2col1, table2col2)
VALUES ('table2col1value',
(SELECT table1.id FROM table1 ORDER BY table1.id DESC LIMIT 1))
;

这是SQL查询：

这是错误：

save_vars <- function(list.of.vars = NULL,
                      prefix = "StatusQuo",
                      path = "data") {
  if(is.null(list.of.vars)) list.of.vars <- ls()
  date_time <- Sys.time()
  if (!is.null(path))
    path <- paste0(path, "/")
  file_name <- paste0(path, prefix, "_", date_time, ".RData")
  save(list = list.of.vars, file = file_name)
}

您知道Liquibase是否能够处理这样的嵌套查询吗？

Answer 1

您可以尝试以这种方式选择插入内容

INSERT INTO table2 (col1, col2)
select  'table2col1value' , id 
FROM table1 
ORDER BY table1.id DESC 
LIMIT 1

Answer 2

我最终使用<changeSet><sql>而不是<changeSet><sqlFile>进行完全相同的查询，并且有效：

    <changeSet id="1" author="me">
        <sql> 
INSERT INTO table1(table1col1, table1col2)
VALUES (table1col1value, table1col2value)
;
        </sql>
        <sql>
INSERT INTO table2 (table2col1, table2col2)
VALUES (table2col1value,
(SELECT table1.id FROM table1 ORDER BY table1.id DESC LIMIT 1))
;
        </sql>
    </changeSet>

带Liquibase sqlFile的MySQLSyntaxErrorException
