我想触发更新查询,通常使用groovy,我们会执行以下操作:
sql.executeUpdate("update MYTABLE l set field1 where l.id = ${someobj.id}")
以上工作完美但我的问题是我不知道需要更新多少参数。所以我做了一个返回的函数 properttoudate1 = value1,propertytoupdate2 = value2 ..等等.. 然后我将上面的查询修改为
sql.executeUpdate("update MYTABLE l set ${makeQueryString(propertiesToUpdate)} where l.id = ${someobj.id}")
现在它给了我错误::
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''PROPERTY1 = 1' where l.id = 'PROPERTVALUE1'' at line 1
任何想法??
答案 0 :(得分:1)
您需要告诉Groovy该字段名是静态的,不应该被?
by using Sql.expand
替换:
sql.executeUpdate("update MYTABLE l set ${Sql.expand(makeQueryString(propertiesToUpdate))} where l.id = ${someobj.id}")
