我對Matlab很陌生,我試圖將單元更新到Postgresql表中。從Matlab更新Postgresql時出錯
這是我的代碼
s=size(o,1);
for n=1:1:s
colnames={'obj_state_new'};
data = {num2str(2)};
tablename = 'objects';
whereclause = ['WHERE obj_name = "obj', num2str(n), '"']
update(conn,tablename,colnames,data,whereclause)
end
但我得到的是這樣的錯誤:
Error using database/update (line 268) Java exception occurred: java.sql.BatchUpdateException: Batch entry 0 UPDATE objects SET obj_state_new = '2' WHERE obj_name = "obj1" was aborted. Call getNextException to see the cause. at org.postgresql.jdbc2.AbstractJdbc2Statement$BatchResultHandler.handleError(AbstractJdbc2Statement.java:2762) at org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:1999) at org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:421) at org.postgresql.jdbc2.AbstractJdbc2Statement.executeBatch(AbstractJdbc2Statement.java:2929)
Error in scriptingTest (line 18) update(conn,tablename,colnames,data,whereclause)
我測試的連接,它的確定。
有人能指出我正確的方向嗎?
在此先感謝
這並獲得成功。謝謝 – Irene
