I have this table: du -sm table* 323 table.MYD 276 table.MYI 0 table.frm How much tablespace I need to convert it to InnoDb, I found that I need a lot more space for this table type, but I could not find how to calculate this space... The auto-extending data file of InnoDB-3.23.50 will solve your problem. No need to preallocate tablespace any more. I think the following formula usually gives a rough estimate of the needed size: 1.5 x size of the .MYD file + 5 x size of .MYI file.

Query
I have this table definition: table_1 +--+-+--+-+-++ | Field| Type| Null | Key | Default | Extra | +--+-+--+-+-++ | id | int(15) | | PRI | NULL| auto_increment | | Contrato | int(11) | | MUL | 0 || | UserName | varchar(30) | | MUL | || +--+-+--+-+-++ table_2 +--+-+--+-+-++ | Field| Type| Null | Key | Default | Extra | +--+-+--+-+-++ | id | int(11) | | PRI | NULL| auto_increment | | Contrato | int(11) | | | 0 || | Nombre | varchar(50) | | | || | UserName | varchar(15) | | MUL | || +--+-+--+-+-++ table_3 +-+--+--+-+-++ | Field | Type | Null | Key | Default | Extra | | +-+--+--+-+-++ | id | bigint(21) | | PRI | NULL| auto_increment | | UserName| varchar(32) | | MUL | | | | | Saldo | float|| | | | | +-+--+--+-+-++ I need to retrieve the column Saldo from table 3 for each Contrato (could in table 1 and table 2), so i executed this select... SELECT Contrato, Saldo FROM table_3, table_2, table_1 WHERE (table_1.UserName = table_3.UserName) OR (table_2.UserName = table_3.UserName) This select return an error that Contrato is ambiguous. I can not do 2 queries, so the only solution to this is an UNION, but MySQL does not support them yet.. Can someone help me?
