使用第一个表中的某些内容作为接收表的列，将数据从SQL中的一个表移动到另一个表中

Question

Sorry for the long title, but couldn't find something shorter unfortunately. So my problem is the following, I have been given a SQL table with the following columns:

Id_String  |  Date  |  Time  |  Value

Id_String is a number that ranges from 101 to 120. Here is a sample of the data:

101 1982-12-02  07:48:03    0.001
102 1982-12-02  07:48:04    0.002
102 1982-12-02  07:50:04    0.004
102 1982-12-02  07:52:04    0.006
103 1982-12-02  07:52:05    0.006

What I need to do is simple yet I'm not an expert so I'm not sure this can be done in an easy way. I'd like to build a table with the following columns:

Date  |  Time  |  Value_Id_String_101  |  Value_Id_String_102 | ... | Value_Id_String_120

That is, for each date and time I have all the values of the String Ids. Is there a SQL command that I can run on the first table in order to automatically generate the second table? Or should I write a script that does it "manually"?

Thanks a lot.

Use these query

       INSERT INTO TARGET_TABLE (`col1`,`col2`) SELECT `col1`,`col2` FROM SOURCE_TABLE;

    or

 CREATE TABLE newtable LIKE oldtable; INSERT newtable SELECT * FROM oldtable;
