This error occurs when a stored procedure does not contain a matching case statement for a given value. It is a MySQL server error code 1339.

How It Affects Your App

MySQL 1339 ER_SP_CASE_NOT_FOUND is an error that occurs when a stored procedure is called with an incorrect case. This can have a significant impact on an application as it can lead to unexpected results or even cause the application to crash. It can also lead to data integrity issues as incorrect data may be returned or stored in the database. This can be especially problematic if the application relies on the stored procedure to perform critical operations. Therefore, it is important to ensure that the correct case is used when calling stored procedures.

How To Fix

1. Identify the root cause of the MySQL 1339 error:SELECT * FROM table_name WHERE column_name = 'value';
ERROR 1339 (HY000): Got error 'invalid_value' from storage engine
2. Check the table structure and data types of the column in question:DESCRIBE table_name;
+------------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+------------+-------------+------+-----+---------+-------+
| column_name| varchar(255)| YES | | NULL | |
+------------+-------------+------+-----+---------+-------+
3. Check the value being passed to the column:SELECT * FROM table_name WHERE column_name = 'value';
+------------+
| column_name|
+------------+
| value |
+------------+
4. Check the data type of the value being passed to the column:SELECT typeof('value');
+------------+
| typeof('value') |
+------------+
| varchar(255) |
+------------+
5. Update the data type of the column to match the data type of the value being passed:ALTER TABLE table_name MODIFY column_name VARCHAR(255);
6. Test the query again:SELECT * FROM table_name WHERE column_name = 'value';
+------------+
| column_name|
+------------+
| value |
+------------+
