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:

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.
