我不知道为什么这个语法不起作用。 我想创建一个新的表格, 将现有的两个表格合并起来 。
CREATE TABLE blah(
SELECT T1.Q1, T1.Q2, T1.Q3, T1.ID, T1.QOL, T2.ID, T2.L1, T2.L2
FROM T1, T2
WHERE T1.ID = T2.ID)
整个查询是正确的, 只是 AS 丢失了 。
CREATE TABLE blah AS (
SELECT T1.Q1, T1.Q2, T1.Q3, T1.ID, T1.QOL, T2.ID, T2.L1, T2.L2
FROM T1, T2
WHERE T1.ID = T2.ID);
看起来像你失踪了一样 在这里,try
CREATE TABLE blah as (
SELECT T1.BUSINESSNAME, T1.STREETADDRESS, T1.CITYNAME, T1.ID, T1.QOL, T2.ID, T2.L1, T2.L2
FROM T1, T2
WHERE T1.ID = T2.ID)
SELECT T1.Q1, T1.Q2, T1.Q3, T1.ID, T1.QOL, T2.ID, T2.L1, T2.L2
INTO blah
FROM T1, T2
WHERE T1.ID = T2.ID
The name of column ID is specified two times: in T1.ID and in T2.ID. At least in postgres this is not accepted.
您可以使用下面的代码创建表格
SELECT *
INTO #MyNewTable
FROM SourceTale
