Copy data from one table to another when column sizes are different

Question

I have two tables t1 (old) with 4 columns and t2 (new table) with 6 columns.

I want to copy the data from t1 to t2 with date and 'ÝES' as default values in T2 as these values are not available in T1.

• T1 - 4 columns (c1, c2, c3, c4)
• T2 - 6 columns (c1, c2, c3, c4, getdate(), 'ÝES') like I need

Please help me with this.

Answer 1

这应该得到期望的结果：

insert into T2 (c1,c2,c3,c4,c5,c6) select c1,c2,c3,c4,sysdate, 'ÝES' from T1;
