What is the result of performing a statement in PDO if there are two selected questions in it? Consider this table:
ab ------ a 1b2c3d4e5f6 and this PDO query :
$ sql = $ pdo- & gt; Ready ("A table from selection where B & gt; 3; selects a table where B <3;"); $ Sql- & gt; Executed (); What would happen $ sql- & gt; ReceiveL () return?
UNION ALL Combine questions using:
Select from the table where B & gt; 3; Choose a table from Unius all where B & lt; 3; The first selection returns a record D for the statement A, E, F. The second statement gives b for A. The result is found in a single return
D, E, F, A, B I now have my points;) (just jokingly)
