我是 java 桌面应用程序的初学者，我试图在我的表中插入一些数据，我得到以下回复“列计数与第 1 行的值计数不匹配”这是我的查询

 String sql = "insert into cataloguetb(title_statement,aurthurs_name,edition_statement,book_title,publisher_name"
                   + "place_of_publication,year_of_publication,isbn_no,index_no,pagenRomannuem,pagneArabi,illuss,size_of_book"
                   + "otherAurthurs,addEntries,length_in_cm,accessionNO,call_No1,call_No2,call_No,call_No4)values ('"+(titleStatement)+"','"+(aurthursName)+"'"
                   + "'"+(editionStatement)+"','"+(bookTitle)+"','"+(publisherName)+"','"+(placeOfPublication)+"','"+(yearOfPublication)+"'"
                   + "'"+(isbnNo)+"','"+(indexNo)+"','"+(pageRoman)+"','"+(pageArabic)+"','"+(illustration)+"','"+(size)+"','"+(otherAuthurs)+"'"
                   + "'"+(addedEntries)+"','"+(lengthOfBook)+"','"+(accessionNo)+"','"+(calNo1)+"','"+(calNo2)+"','"+(calNo3)+"','"+(calNo4)+"')";

我已经尝试了很多解决方案，即使来自 stacflowoverflow 似乎也没有解决方案，感谢您的帮助。

这是因为您要输入的列数和您输入的数据（列的值）不同

您的代码的输出将是这样的

insert into cataloguetb(title_statement,aurthurs_name,edition_statement,book_title,publisher_nameplace_of_publication,year_of_publication,isbn_no,index_no,pagenRomannuem,pagneArabi,illuss,size_of_bookotherAurthurs,addEntries,length_in_cm,accessionNO,call_No1,call_No2,call_No,call_No4)values (.......)

这意味着您尝试插入 19 列但给出 21 个值。所以错误。

好吧，这不是正确的插入方式。最好像这样使用 PreparedStatement

PreparedStatement pt=con.prepareStatement("insert into table (x,y) values(?,?");
pt.setString(1,value_for_x);
pt.setString(2,value_for_y);
pt.executeUpdate();

您需要在行尾的字段中使用尾随逗号。尝试这个：

String sql = "insert into cataloguetb(title_statement,aurthurs_name,edition_statement,book_title,publisher_name,"
                   + "place_of_publication,year_of_publication,isbn_no,index_no,pagenRomannuem,pagneArabi,illuss,size_of_book,"
                   + "otherAurthurs,addEntries,length_in_cm,accessionNO,call_No1,call_No2,call_No,call_No4) values ('"+(titleStatement)+ "','"+(aurthursName)+"',"
                   + "'"+(editionStatement)+"','"+(bookTitle)+"','"+(publisherName)+"','"+(placeOfPublication)+"','"+(yearOfPublication)+"',"
                   + "'"+(isbnNo)+"','"+(indexNo)+"','"+(pageRoman)+"','"+(pageArabic)+"','"+(illustration)+"','"+(size)+"','"+(otherAuthurs)+"',"
                   + "'"+(addedEntries)+"','"+(lengthOfBook)+"','"+(accessionNo)+"','"+(calNo1)+"','"+(calNo2)+"','"+(calNo3)+"','"+(calNo4)+"')";
