Question

我是java桌面应用程序的初学者，我试图将一些数据插入到我的表中，我得到以下回复“colown count与第1行的值计数不匹配”这里是我的查询

 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，即使是从stacflowoverflow，似乎没有解决方案感谢您的帮助。

Answer 1

这是因为您要输入的列数和您输入的数据（列的值）不相同

您的代码输出将是这样的

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 (.......)

这意味着你试图插入19列，但给出21个值。所以错误。

这不是正确的插入方式。最好是像这样使用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();

Answer 2

您需要在行末尾的字段上使用尾随逗号。试试这个：

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)+"')";

列数与第1行的值计数不匹配
