How to query if a certain field in db2 contains a specific string?
You can use the LIKE statement to query if a field contains a certain string. Here is an example:
SELECT * FROM 表名 WHERE 字段名 LIKE '%字符串%'
In the example above, the table name refers to the name of the table you want to query, the column name is the name of the column you want to search, and the string is the text you want to search for. The % symbol is a wildcard that represents matching any character. If you want to search for fields that start with a specific string, you can use ‘string%’. If you want to search for fields that end with a specific string, you can use ‘%string’.
Please note that the query statement mentioned above will return all rows that contain the specified string. If you only want to return a specific field that includes the specified string, you can specify the corresponding field name in the query statement.
