I'm starting to pull my hair out here is something like this even possible?
DECLARE var1 int; DECLARE var2 int; DECLARE var3 int; SELECT var1:=id, var2:=foo, var3:=bar from page WHERE name="bob"; CALL someAwesomeSP (var1 , var2 , var3 ); The above doesn't work but i am trying to figure out how I would accomplish this. My ultimate goal here is to call a select and than call stored proc with data from select.
Thanks

DECLARE var1 int; DECLARE var2 int; DECLARE var3 int; SELECT var1:=id, var2:=foo, var3:=bar from page WHERE name="bob"; CALL someAwesomeSP (var1 , var2 , var3 );
@@ - System Variable @@ is used for system variables. Using different suffix with @@ , you can get either session or global value of the system variable.
The syntax for assigning a value to a SQL variable within a SELECT query is @ var_name := value , where var_name is the variable name and value is a value that you're retrieving. The variable may be used in subsequent queries wherever an expression is allowed, such as in a WHERE clause or in an INSERT statement.
The following discussion describes the syntax options for setting system variables: To assign a value to a global system variable, precede the variable name by the GLOBAL keyword or the @@GLOBAL. qualifier: SET GLOBAL max_connections = 1000; SET @@GLOBAL.
This worked for me.
DECLARE var1 int; DECLARE var2 int; DECLARE var3 int; SELECT id, foo, bar INTO var1, var2, var3 from page WHERE name="bob"; CALL someAwesomeSP (var1 , var2 , var3 ); Thanks to Zec. The first link helped me understand the correct syntax or at least what is working for me.

For MySQL, please take a look this example code:
-- Init variables SET @var1 = 0; SET @var2 = 0; SET @var3 = 0; SELECT VALUE1, VALUE2, VALUE3 INTO @var1, @var2, @var3 FROM COOL_TABLE WHERE VALUE_ID = 12345; -- Then you can use declared variables SELECT * FROM ANOTHER_TABLE WHERE VALUE1 = @var1 AND VALUE2 = @var2 If you love us?
