Column 'name' in where clause is ambiguous

这个错误通常是由于 SQL 查询中使用了多个表,并且这些表中都有一个相同的列名,导致查询时无法确定到底是哪个表的列。解决这个问题的方法是在查询中指定列所属的表名或者表的别名。例如:
```
SELECT t1.name, t2.age FROM table1 t1, table2 t2 WHERE t1.name = 'John' AND t2.name = 'Smith';
```
在这个例子中,我们使用了表的别名 t1 和 t2 来指定每个列所属的表,从而避免了列名冲突的问题。

column 'name' in where clause is ambiguous
这个错误提示是因为在 SQL 查询语句中,WHERE 子句中的列名“name”在多个表中都存在,导致无法确定具体指向哪个表的列。需要在 WHERE 子句中明确指定列所属的表,例如使用“table_name.name”来代替“name”。
Column 'BEGDA' in where clause is ambiguous
The error message "Column 'BEGDA' in where clause is ambiguous" occurs when there are multiple columns with the same name in the tables being queried, and the database engine cannot determine which column you are referring to in the WHERE clause. To resolve this issue, you need to specify the table alias or the table name along with the column name in the WHERE clause. For example:
```sql
SELECT *
FROM table1
WHERE table1.BEGDA = '2022-01-01';
```
In this example, "table1" is the alias or the table name that uniquely identifies the column "BEGDA". Make sure to use the appropriate alias or table name based on your specific query.
