超过4000用到了BLOB类型，新增报错

最近做项目需要往日志表里存放内容，由于字段可能超过4000用到了BLOB类型，数据库oracle

小于4000的正常，超过4000的就报错，报错信息：Cause: java.sql.SQLException: ORA-06502: PL/SQL: numeric or value error: raw variable length too long

ORA-06512: at "SYS.UTL_RAW", line 224

这个是我的sql

INSERT INTO "JGPT"."SYS_API_REQUEST_LOG" ( "ID", "CREATE_TIME", "API_PATH", "REQUEST_METHOD", "REQUEST_DATA", "RESPONSE_STATUS", "RESPONSE_DATA", "ERROR_LOG", "CREATE_BY" )

        'GET',
        utl_raw.cast_to_raw ( '3C3F786D6C2076657273696F6E3D22312E302220656E636F64696E673D225554462D3822207374616E64616C6F6E653D22796573223F3E0A203C53656172636844617461204E756D6265723D2232223E0A20202020203C706172744E756D6265723E46445A313532323131303434323931303031333C2F706172744E756D6265723E0A203C2F536561726368446174613E' ),

        NULL,

    );

怎么修改才能满足超过4000长度正常存储呢？

参数化sql，不要拼接成一个长长的字符串执行
在oracle里varchar2类型最多3500左右，如果少于这个数，你的列直接varchar2就行了，不需要blob
而如果你的列是blob，就应该参数化sql，直接传入byte数组，而不是拼接成字符串
sql字符串本质上还是varchar，然后再转成blob，它还是会受3500的限制

字段是BLOB类型么，转一下再存试试
to_blob('3C3F786D6C2076657273696F6E3D22312E302220656E636F64696E673D225554462D38223F3E3C7461736B3E3C706172743E3C6E756D6265723E46445A313532323131303434323931303031333C2F6E756D6265723E3C6E616D653E3C2F6E616D653E3C76657273696F6E3E3C2F76657273696F6E3E3C697465726174696F6E3E3C2F697465726174696F6E3E3C70686173653E3C2F70686173653E3C73746174653E3C2F73746174653E3C2F706172743E3C2F7461736B3E')
