Error Code

S03012

Error Message

Data insertion failed: Number of columns in the data to insert doesn't match the target table. If you're trying to persist table, a table with the same name may exist on disk. Consider changing the table name, adjusting the data schema, or deleting the existing table from persistentDir and retrying. RefId: S03012

Probable Causes

This error occurs in the following cases:

1. When appending data to a stream table (with append! or insert into), its schema does not match the table schema.
2. When calling enableTableShareAndPersistence, a table with the same name already exists in the persistence directory, and the table schema does not match that specified in the function.

Solutions

1. For the first case, check and modify the schema of data to be appended.
2. For the second case, check and modify the schema of table specified in enableTableShareAndPersistence, or clean up the persisted files before enabling persistence.
