我在derby db中创建表时遇到错误请帮忙。
首先我正在搜索数据库中是否存在该表，如果不是我正在创建表但是我得到并且很奇怪异常这个相同的查询在Oracle本地数据库中正常工作。
String driver = "org.apache.derby.jdbc.EmbeddedDriver";
String dbName = "ServerDetails";
String connectionURL = "jdbc:derby:" + dbName + ";create=true";
Class.forName(driver);
Connection conn = DriverManager.getConnection(connectionURL);
PreparedStatement ps = null;
ResultSet rs = null;
//PreparedStatement createPS = null;
ResultSet createRS = null;
//String checkQuery = "select * FROM ALL_TABLES WHERE table_name like UPPER('XX_SERVER_DETAILS')";
String tableScript = "CREATE TABLE XX_SERVER_DETAILS"
+ "("
+ " USERNAME1 VARCHAR2(10 BYTE) NOT NULL,"
+ " PASSWORD1 VARCHAR2(10 BYTE) NOT NULL,"
+ " SERVER1 VARCHAR2(50 BYTE) NOT NULL,"
+ " USERNAME2 VARCHAR2(10 BYTE) NOT NULL,"
+ " PASSWORD2 VARCHAR2(10 BYTE) NOT NULL,"
+ " SERVER2 VARCHAR2(50 BYTE) NOT NULL"
+ ")";
DatabaseMetaData dbmd = conn.getMetaData();
rs = dbmd.getTables(null, null, "XX_SERVER_DETAILS",null);
if(rs.next())
{
System.out.println("Table "+rs.getString("TABLE_NAME")+"already exists !!");
}
else
{
System.out.println("Write your create table function here !!!");
ps = conn.prepareStatement(tableScript);
createRS = ps.executeQuery();
//createPS = conn.prepareStatement(tableScript);
//createRS = createPS.executeQuery();
conn.commit();
ps.close();
rs.close();
//createPS.close();
//createRS.close();
}

答案 0 :(得分：1)
这是一个愚蠢的错误抱歉发布问题脚本将是这样的东西
String tableScript = "CREATE TABLE XX_SERVER_DETAILS"
+ "("
+ " USERNAME1 VARCHAR(10) NOT NULL,"
+ " PASSWORD1 VARCHAR(10) NOT NULL,"
+ " SERVER1 VARCHAR(50) NOT NULL,"
+ " USERNAME2 VARCHAR(10) NOT NULL,"
+ " PASSWORD2 VARCHAR(10) NOT NULL,"
+ " SERVER2 VARCHAR(50) NOT NULL"
+ ")";
Derby不接受varchar2。因为我重用了oracle的查询，所以它给出了错误。
