我正在尝试将数字/文本插入表中,但当程序尝试插入文本时,我收到错误
net.ucanaccess.jdbc.UcanaccessSQLException: UCAExc:::4.0.2 unexpected token: EX1 required: )
以下是我的相关代码:
try (Connection conn = DriverManager.getConnection(
"jdbc:ucanaccess://" + dbPath
+ ";newdatabaseversion=V2010"
)) {
DatabaseMetaData dmd = conn.getMetaData();
try (ResultSet rs = dmd.getTables(null, null, tableName, new String[] { "TABLE" })) {
try (Statement s = conn.createStatement()) {
ResultSet resultSet;
String tableName = "Database";
s.executeUpdate("CREATE TABLE " + tableName +" ( [SUBJID]
INTEGER, [PARAMCD] TEXT, [PARAM] TEXT, [AVAL] DOUBLE)");
String s1="Text Ex1";
String s2="Text Ex2";
int a=3;
double b=2;
resultSet = s.executeQuery("SELECT * FROM " + tableName);
s.executeUpdate("INSERT INTO " + tableName
+ " ( SUBJID, PARAMCD, PARAM, AVAL)"
+ " VALUES ( "+ a+", " + s1 + ", " + s2 +" , " + b +" )");
在我看来,当出现空格时会导致错误。我已经尝试将s1更改为“TextEx1”,将s2更改为“TextEx2”,这会给我net.ucanaccess.jdbc.UcanaccessSQLException: UCAExc:::4.0.2 user lacks privilege or object not found: TEXTEX1
的错误。
提前感谢任何人提供的任何帮助。

你想做这样的事情:
String sql = "INSERT INTO [" + tableName + "] (SUBJID, PARAMCD, PARAM, AVAL) VALUES (?,?,?,?)";
PreparedStatement ps = conn.prepareStatement(sql);
ps.setInt(1, a);
ps.setString(2, s1);
ps.setString(3, s2);
ps.setDouble(4, b);
ps.executeUpdate();
