Data truncated for column ‘xxx‘ at row 1
在开发Java 项目的时候我新建立了一张表，然后发现了一个问题：
Caused by: java.sql.SQLException: Data truncated for column 'uuid' at row 1 at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:965) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3933) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3869) at com.mysql.jdbc.MysqlIO.sendCommand(MysqlIO.java:2524) at com.mysql.jdbc.MysqlIO.sqlQueryDirect(MysqlIO.java:2675) at com.mysql.jdbc.ConnectionImpl.execSQL(ConnectionImpl.java:2465) at com.mysql.jdbc.PreparedStatement.executeInternal(PreparedStatement.java:1915) at com.mysql.jdbc.PreparedStatement.execute(PreparedStatement.java:1254) at com.alibaba.druid.pool.DruidPooledPreparedStatement.execute(DruidPooledPreparedStatement.java:498) at org.apache.ibatis.executor.statement.PreparedStatementHandler.update(PreparedStatementHandler.java:47) at org.apache.ibatis.executor.statement.RoutingStatementHandler.update(RoutingStatementHandler.java:74) at org.apache.ibatis.executor.SimpleExecutor.doUpdate(SimpleExecutor.java:50) at org.apache.ibatis.executor.BaseExecutor.update(BaseExecutor.java:117) at org.apache.ibatis.executor.CachingExecutor.update(CachingExecutor.java:76) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.apache.ibatis.plugin.Plugin.invoke(Plugin.java:64) at com.sun.proxy.SqlSessionInterceptor.invoke(SqlSessionTemplate.java:427)
在开发代码的时候发现数据库有这个SQL 报错，回到数据库发现，是字段选择有问题。
我应该选择varchar才对。
