执行失败，报> 1064 - Not implement toSqlImpl function，从2.5一路升级上来均运行正常，V3.2.7 运行失败！ 将自定义变量，替换掉，运行正常。

Expected behavior (Required)

正常运行，不报错

Real behavior (Required)

1064 - Not implement toSqlImpl function

StarRocks version (Required)

V3.2.7

表MVNAME可用此数据，其它ods表字段ss_dt datetime NULL DEFAULT CURRENT_TIMESTAMP COMMENT "SS更新时间戳"，均为主键表。

INSERT INTO mvname(mvname, tbname, colname, svalue, evalue, vals, isok, gmt_update) VALUES ('dws.dws_tb_a_mv', 'ods.ods.ods_tb_b_rt', 'create_time', '2024-05-30 20:26:28', '2024-05-30 20:26:28', NULL, 0, '2024-05-30 20:50:10');
