我正在利用我的施压器将数据插入邮政gresql db。 我有1962年9份记录待加。 我正试图一次插入所有记录。 但是,如果我把更多的6k记录转至询问中,我正想到:org.postgresql.util.PSQLException: I/O错误是在向后台发送时发生的。
因此,在邮政盖尔的一段时间插入记录的数量没有任何限制?
Mybatis code.
{ @Insert({ "<script>","insert into temp_overdrive_csv_dtls (lpat_library_card_number,day_of_use,sessions,minutes_read,hours_read,sys_created_by)","values ", "<foreach collection= recordList item= record separator= , >","(#{record.lpatLibraryCardNumber},#{record.dayofUse}, #{record.sessions}, #{record.minutesRead}, #{record.hoursRead}, #{record.sysCreatedBy})","</foreach>", "</script>" })public Integer insert(@Param("recordList") List<CsvRecord> recordList);
Error.
Error updating database. Cause: org.postgresql.util.PSQLException: An I/O error occurred while sending to the backend.
