当前执行 INSERT 语句时,对于有不符合目标表格式的数据,默认的行为是过滤,比如字符串超长等。但是对于有要求数据不能够被过滤的业务场景,可以通过设置会话变量 enable_insert_strict 为 true(默认true,建议为true)来确保当有数据被过滤掉的时候,INSERT 不会被执行成功。也可以通过命令:set enabl

当执行INSERT INTO语句时,对于不符合目标表格式的数据(例如,字符串超长),默认的行为是过滤。对于数据不能被过滤的业务场景,可以通过设置会话变量enable_insert_strict为true来确保当有数据被过滤的时候,INSERT INTO语句不会成功执行。 因为StarRocks的INSERT INTO复用导入数据的逻辑,所以每一次INSERT INTO语句都会产生一个...
