mysql stored procedure error (1172, 'Result consisted of more than one row')

Question

When trying to run the following stored procedure from django, I get an OperationError (1172, \'Result consisted of more than one row\') Any idea what I might be doing wrong

Answer 1

Your SELECT...INTO queries give result sets with more then one record. The WHERE filters are incorrect - they compare two the same values StoreID = storeId. Rename IN storeId int parementer to another name. For example - IN storeId_param int

The query will be like this -

SELECT S1000IncreaseChoices INTO changeType FROM store_store WHERE StoreID = storeId_param;
