Question

在域级别的grails 2.3.4中，我添加了一段新代码：

static mapping = {
    text type: "text"
}

之前我只有简单的varblle与名称文字。我将我的sql类型更改为文本（TEXT - 65,535字节）。但是当我试图节省5万个字符时，我得到了：

Data truncation: Data too long for column 'text' at row 1. Stacktrace follows:

删除并创建新数据库。它应该正常工作..

将类型从简单字符串更改为文本后的Grails - 对于第1行的列“text”，数据太长
