the same as the file generated during export. Otherwise, the copy fails. By default, the imported file is a tab-separated file, the files generated by DTs use a lot of quotation marks or parentheses to separate fields. Therefore, the text exported by DTs and the text exported by BCP cannot be universal, otherwise, the "unexpected EOF encountered in the BCP data file" error will occur. As follows: NullStart copying...Sqlstate = s1000, nativeerror = 0E

Today, a vendor asked me a question. If you want to change the data type of a field in a table, whether it is a field type in View also responds to automatic changes.
