Question

当我运行以下SQL查询时，我收到以下错误：

java.sql.SQLException: ORA-01747: invalid user.table.column, table.column, or column specification

String strQuery = "UPDATE themed_night SET theme_night_name = ?, theme_night_date = TO_DATE(?, 'dd-MM-yy'), theme_night_description = ?, WHERE theme_id = ?";
        PreparedStatement stmt = conn.prepareStatement(strQuery);//prepare the SQL Query
        stmt.setString(1, title);
        stmt.setString(2, output);
        stmt.setString(3, details);
        stmt.setString(4, themeID);

我的SQL查询语法是否正确？我仔细检查了列，并输入了正确的名称。

Answer 1

你的陈述中有一个额外的逗号。正确的陈述应该是

String strQuery = "UPDATE themed_night SET theme_night_name = ?, theme_night_date = TO_DATE(?, 'dd-MM-yy'), theme_night_description = ? WHERE theme_id = ?";

此外，您可能需要用单引号括起一些值（虽然我不确定）

java.sql.SQLException：ORA-01747
