在oracle中提示用户表

Question

如何提示用户在Oracle中输入表名？我想在选择之后提供关于桌子的报告。我有这个：

SELECT column_name "Column Name", data_type "Data Type", data_length "Data Length",
                   data_precision "Data Precision", nullable "NULLS Allowed?"
FROM user_tab_columns
WHERE table_name = &;

我知道＆amp;允许用户输入数据吗？

SELECT column_name "Column Name", data_type "Data Type", data_length "Data Length",
                   data_precision "Data Precision", nullable "NULLS Allowed?"
FROM user_tab_columns
WHERE table_name = UPPER('&tabname')
