I have been away from sql for awhile, and can't seem to figure out how to
write a simple query for two tables.
Table 1 has many columns, two of which are hID and vID. Table 2 has two
columns, ID and name. The hID and vID in table 1 correspond to the IDs in
table 2. I want to make a query so I get all the columns from table 1, but
substitute the names from table 2 for the hID and vID values. For example,
Table 1:
col 1, col 2, hID, vID, col 3
A B 1 2 C
Table 2:
ID, name
1 fred
2 sam
Query result:
col1, col 2, hName, vName, col 3
A B fred sam C
select a, b, c,
hTable.name as hName,
vTable.name as vName
from Table1,
Table2 as hTable,
Table2 as vTable
where hId = hTable.ID and vID = vTable.ID
or
select a, b, c,
hTable.name as hName,
vTable.name as vName
from Table1
left join Table2 as hTable on hID = hTable.ID
left join Table2 as vTable on vID = vTable.ID
