Prosim, tento select z sqlite v mysql #1248 - Every derived table must have its own alias . Kde je chybka? Děkuji za pomoc
SELECT * FROM (SELECT * FROM (SELECT * FROM (SELECT 'news_novinky' AS news,id,idd,img,datumc AS datumo,datumc AS datumd,titulek FROM news_novinky ORDER BY datumc DESC LIMIT 5) UNION ALL SELECT * FROM (SELECT 'news_kalendar' AS news,id,idd,img,datumo,datumd,titulek FROM news_kalendar WHERE datumd >= DATETIME('NOW','localtime') ORDER BY datumd LIMIT 5) UNION ALL SELECT * FROM (SELECT 'news_souteze' AS news,id,idd,img,datumo,datumd,titulek FROM news_souteze WHERE datumd >= DATETIME('NOW','localtime') ORDER BY datumd LIMIT 5)) x ORDER BY DATETIME('NOW','localtime') > datumo ASC) |

Za podotazem uzavřeným v závorce, který používáte v selectu, vyžaduje mysql alias.
SELECT *
FROM (SELECT *
FROM (SELECT *
FROM (SELECT 'news_novinky' AS news,
id,
idd,
img,
datumc AS datumo,
datumc AS datumd,
titulek
FROM news_novinky
ORDER BY datumc DESC
LIMIT 5) cokoliv
UNION ALL
SELECT *
FROM (SELECT 'news_kalendar' AS news,
id,
idd,
img,
datumo,
datumd,
titulek
FROM news_kalendar
WHERE datumd >= Datetime('NOW', 'localtime')
ORDER BY datumd
LIMIT 5) cokoliv
UNION ALL
SELECT *
FROM (SELECT 'news_souteze' AS news,
id,
idd,
img,
datumo,
datumd,
titulek
FROM news_souteze
WHERE datumd >= Datetime('NOW', 'localtime')
ORDER BY datumd
LIMIT 5) cokoliv
) x
ORDER BY Datetime('NOW', 'localtime') > datumo ASC) cokoliv Pokud obalíte poddotazy jen pro union all, tak tam alias mít nemusí... SELECT *
FROM ((SELECT 'news_novinky' AS news,
id,
idd,
img,
datumc AS datumo,
datumc AS datumd,
titulek
FROM news_novinky
ORDER BY datumc DESC
LIMIT 5)
UNION ALL
(SELECT 'news_kalendar' AS news,
id,
idd,
img,
datumo,
datumd,
titulek
FROM news_kalendar
WHERE datumd >= Datetime('NOW', 'localtime')
ORDER BY datumd
LIMIT 5)
UNION ALL
(SELECT 'news_souteze' AS news,
id,
idd,
img,
datumo,
datumd,
titulek
FROM news_souteze
WHERE datumd >= Datetime('NOW', 'localtime')
ORDER BY datumd
LIMIT 5)) x
ORDER BY Datetime('NOW', 'localtime') > datumo ASC |

Kajman:
Paráda, děkuji, to jsem potřeboval ... jen jsem Datetime('NOW', 'localtime') zaměnil za NOW() a je to OK |
