Question

SELECT COUNT(packages.id) AS rowCount,
       packages.packageCode
FROM packages
INNER JOIN prices ON packages.packageCode = prices.packageCode
WHERE TRUE packageCode LIKE '%EPOP%'
ORDER BY packageName ASC

where子句有错误，任何人都可以帮忙...

Answer 1

只需更改where packages.packageCode而不是packageCode的子句，因为两个表中的packageCode都会出现歧义错误，并从where子句中删除TRUE个字。

SELECT COUNT(packages.id) AS rowCount,
       packages.packageCode
FROM packages
INNER JOIN prices ON packages.packageCode = prices.packageCode
WHERE packages.packageCode LIKE '%EPOP%'
ORDER BY packages.packageName ASC
