When performing bulk data loading, it is not uncommon to encounter issues with data conversion. One of the common errors is "Type Mismatch or Invalid Character for Specified Codepage." This error occurs when the data in the source file is not compatible with the target database's encoding. In this guide, we will explore the causes of this error and provide solutions to fix it.
Causes of Type Mismatch or Invalid Character for Specified Codepage Error
- Data in the source file is not encoded using the same character set as the target database.
- The source file contains invalid characters that cannot be converted to the target database's encoding.
- The bulk load operation is trying to insert data into a column that is not compatible with the data type of the source file.
Solutions for Type Mismatch or Invalid Character for Specified Codepage Error
- Check the encoding of the source file and make sure it matches the target database's encoding. You can use a text editor that supports multiple encodings to convert the file to the correct encoding.
- Remove invalid characters from the source file. You can use a text editor to search and replace invalid characters with valid ones.
- Specify the correct data type for the target column. You can use the CAST or CONVERT function to convert the data to the correct data type.
Step-by-Step Guide to Fix Type Mismatch or Invalid Character for Specified Codepage Error
- Check the encoding of the source file using a text editor that supports multiple encodings.
- If the encoding of the source file is not compatible with the target database's encoding, convert the file to the correct encoding using the text editor.
- If the source file contains invalid characters, use the search and replace function in the text editor to remove them.
