Oracle中的select into

5星 · 资源好评率100%

Oracle中的select into Oracle中没有select into的用法！在某些数据库中有select into的用法,用法是: select valueA,valueB into tableB from tableA; 上面这句语句的意思是将tableA表中的valueA和valueB字段的值和结构添加到tableB中,tableB表需不存在。在Oracle中select into的等价用法 create table tableB as select valueA,valueB from tableA;

The syntax for Oracle SQL `SELECT * INTO` statement is different from the standard SQL. In Oracle SQL, you can use the `CREATE TABLE AS SELECT` statement to achieve the same result: ``` CREATE TABLE new_table AS SELECT * FROM old_table; ``` In this syntax, `new_table` is the name of the table you want to create with the same structure as the `old_table`. The `SELECT *` statement selects all columns from the `old_table`. The `CREATE TABLE AS SELECT` statement creates a new table and inserts the selected data into it. Note that the `new_table` must not already exist before running this statement. If it does, you will get an error.
