Hello, I'm relatively new to mysql and I've come across a problem while trying to insert values from
multiple tables into a single, existing table. Here's the syntax that I'm using: insert into table1 (col1,col2,col3,col4) select Foo.col1, Foo.col2, Bar.col3, Bunk.col4 from table2 as Foo, table3 as Bar, table4 as Bunk where Foo.col1 = 5 and Bar.col1 = 5 and Bunk.col1 = 5; This works fine so long as the where clause is true. Now here's my problem: I used AND in the above example however, what I want is for each expression to be evaluated individually, like an OR that will not stop if the first expression is true. So, each of the source tables may or may not satisfy the condition, if they do, then the proper value is inserted into table1, if they do not, then some default value should be inserted into table1 (null). This is an if / else problem but I don't know if mysql supports anything of the sort or if I need to use some sort of script to work around this prolem. Any advice would be greatly appreciated. Thanks.
