我有一个表格,每个栏的数据分布在不同行。 需要帮助将所有数据输入单一数据。
| Column A | Column B | Column C | Column D | Column E |
|---|---|---|---|---|
| Jacob | Joseph | Ben | NULL | NULL |
| Jacob | Joseph | NULL | NULL | Reuben |
| Jacob | Joseph | NULL | Judah | NULL |
我想把所有数据集中在以下一行:
| Column A | Column B | Column C | Column D | Column E |
|---|---|---|---|---|
| Jacob | Joseph | Ben | Judah | Reuben |
进入STSQL,无法到达我想要的地方。 请提供帮助。
起初,我有一份单列单,数据以奇数方式分散到各栏。 经过很多改革之后,我来到这里,通过SQL,进口到SQL。 我尝试在表格中插入一些内容,但无法在单行中安排数据。
你们可以使用合计数和组别来解决这个问题。
SELECT
ColumnA,
ColumnB,
MAX(ColumnC) AS ColumnC,
MAX(ColumnD) AS ColumnD,
MAX(ColumnE) AS ColumnE
FROM
YourTable
GROUP BY
ColumnA, ColumnB;
