I have table A with column id, and table B with columns id and
content.
I am trying to build a query that inserts all ids from table A into
table B, and also sets the "value" field for all these new entries to
a given value.
For example:
#Before the query, the tables are like this:
mysql> select * from a;
+------+
| id |
+------+
| hal |
| ron |
| kip |
| dag |
| bob |
| max |
+------+
mysql> select * from b;
+------+-------+
| id | value |
+------+-------+
| bob | 4 |
| bob | 5 |
| max | 5 |
+------+-------+
# After the query, b is like this:
mysql> select * from b;
+------+-------+
| id | value |
+------+-------+
| bob | 4 |
| bob | 5 |
| dag | 4 |
| hal | 4 |
| kip | 4 |
| max | 4 |
| max | 5 |
| ron | 4 |
+------+-------+
I have been trying variations on the INSERT ... SELECT syntax, but
I suspect this is a dead end. The next best thing I can think
of is building a temporary table that has the values that I want, and
then using INSERT ... SELECT to copy them all into table b.
Can anyone suggest a way to achieve this?
