ucanaccess

问题 I'm beginner with java and using console to compile and run my programs. I'm trying to read data from MS Access .accdb file with ucanaccess driver. As i have added 5 ucanaccess files to C:\Program Files\Java\jdk1.8.0_60\jre\lib\ext, but still getting Exception java.lang.ClassNotFoundException:net.ucanaccess.jdbc.ucanaccessDriver.

问题 This is my first attempt at building something in Java, and the end goal here is to simply import an excel file into a MS Access database. I suspect there's some sort of data incompatibility error, or something that UCA is doing to clean queries, but I don't know enough about Java or UCanAccess to track it down. Here's the query I have assembled, which runs fine to insert data in MS Access directly: INSERT INTO XXXX_XA_Data_1 ([Date],[Fund Ticker],[Unique ID],[Cash & Cash Equiv],[Mkt Value of

问题 I'm writing a program using JDBC/UCanAccess and I'm finding when I create one of the tables, instead of creating four columns with the DateTime format, it also applies the same format to the next column, displacing the other formats: CREATE TABLE Person ( Id INT NOT NULL PRIMARY KEY GENERATED ALWAYS AS IDENTITY (START WITH 1, INCREMENT BY 1), Name VARCHAR(40), Surname VARCHAR(40), Card VARCHAR(9), Email VARCHAR(30) ); CREATE TABLE Place ( Id INT NOT NULL PRIMARY KEY GENERATED ALWAYS AS

问题 I have a Microsoft Access database with an OLE Object field holding a Microsoft Word document.

问题 This question already has answers here : SQL INSERT without specifying columns. What happens? (6 answers) Closed 4 years ago . My program always reads the first column in the Access database as the 2nd column, the 2nd one as the 3rd column and so on, but the last column it reads as the first column. public void actionPerformed(ActionEvent e) { try{ String query = "insert into Staff values ('2', 'w', 'w', 'w', 'e', 'w', 'd','d','end')"; stmt.executeUpdate(query); status.setText("1 row of

问题 I am using UCanAccess for manipulating an Access database. When calling executeUpdate I get the exception: net.ucanaccess.jdbc.UcanaccessSQLException: UCAExc:::3.0.2 Unexpected page type 1 (Db=db.accdb;Table=MyTable;Index=PrimaryKey) It only occurs when trying to update one specific row - I already know how to fix this in the Access DB. The problem is with the Logger, after this exception is thrown and I catch it, I log an info message and it is not shown, all of the next log messages are not

问题 I'm in the middle from migrating from the JDBC-ODBC bridge driver to the UCanAccess driver. In doing this, I'm facing the following problem: The UCanAccess driver returns all columnames in UPPERCASE, but I need them to be CamelCase. Any ideas?

(That is, they are no longer forced to UPPERCASE.) (Original Answer) Since
