- Reading Faulty CSV Files 15691
- CSV files can come in all shapes and forms, with some presenting many errors that make the process of cleanly reading them inherently difficult. To help users read these files, DuckDB supports detailed error messages, the ability to skip fa
...nes and the possibility of storing faulty lines in a temporary table to assist users with a data cleaning step. Structural Errors DuckDB supports the detection and skipping of several different structural errors. In this section, we will go over each e...owing table: CREATE TABLE people (name VARCHAR, birth_date DATE); DuckDB detects the following error types: CAST : Casting errors occur when a column in the CSV file cannot be cast to the expected schema value. For example, the line Pedro,The 90s would...cause an error since the string The 90s cannot be cast to a date. MISSING COLUMNS : This error occurs if a line in the CSV file has fewer... - https://man.mtool.work/duckdb/2.0/data/csv/reading_faulty_csv_files.html
- Out of Memory Errors 11269
- DuckDB has a state of the art out-of-core query engine that can spill to disk for larger-than-memory processing. We continuously strive to improve DuckDB's scalability and prevent out of memory errors whenever possible. That said, you may s
...till experience out-of-memory errors if you run queries with multiple blocking operators , certain aggregate functions (such as string_agg() or aggregates with...an ORDER BY clause ), or if you have very little available memory compared to the dataset size. Types of “Out of Memory” Errors Out of memory errors mainly occur in two forms: OutOfMemoryException Most of the time DuckDB runs out of memory with an Ou...on-rss:770031964kB, file-rss:0kB, shmem-rss:0kB, UID:1000 pgtables:1814612kB oom_score_adj:0 Troubleshooting Out-of-Memory Errors To prevent out-of-memory errors, please consult the “Out-of-Memory” issues page of the Performance Guide.

- Troubleshoot 9421
- Overview This page collects common issues encountered when using the DuckDB Go client, together with their workarounds. Because the client uses cgo to embed DuckDB, most build problems are cgo or linker problems. If you run into a problem t
...hat is not covered here, search the client's issue tracker on GitHub. Classifying DuckDB Errors The client returns a *duckdb.Error for errors reported by DuckDB. Use errors.As to handle these errors by category without...parsing their messages: _, err := db.Exec(query) if err != nil { var duckdbError *duckdb.Error if errors.As(err, &duckdbError) { switch duckdbError.Type { case duckdb.ErrorTypeCatalog: // Handle a missing table, view, or other...ErrorTypeOutOfRange , and ErrorTypeInvalidInput . The Msg field contains the error message. undefined: conn and Other cgo Errors An undefined: conn error while building means the Go compiler has decided cgo is unavailable, so the DuckDB bindings were... - https://man.mtool.work/duckdb/2.0/clients/go/troubleshoot.html
- Internal Errors 9345
- Internal errors signal an assertion failure within DuckDB. They usually occur due to unexpected conditions or errors in the program's logic. For example, running issue 17002 on DuckDB 1.2.1 results in an internal error. INTERNAL Error: Atte

Internal errors are by definition bugs that should never happen so the code path is never tested.

- Crashes 8906
- DuckDB is thoroughly tested via an extensive test suite. However, bugs can still occur and these can sometimes lead to crashes. This page contains practical information on how to troubleshoot DuckDB crashes. Types of Crashes There are a few

- Syntax Highlighting 8754
- Syntax highlighting in the CLI is available for macOS, Linux and Windows. SQL queries that are written in the shell are automatically highlighted using syntax highlighting. There are several components of a query that are highlighted in dif

Error Highlighting The shell has support for highlighting certain errors. In particular, mismatched brackets and unclosed quotes are highlighted in red (or another color if specified). This highl...ighting is automatically disabled for large queries. In addition, it can be disabled manually using the .render_errors off command.... - https://man.mtool.work/duckdb/2.0/clients/cli/syntax_highlighting.html
- Configuration 8603
- DuckDB has a number of configuration options that can be used to change the behavior of the system. The configuration options can be set using either the SET statement or the PRAGMA statement . They can be reset to their original values usi

- Pragmas 8315
- The PRAGMA statement is a SQL extension adopted by DuckDB from SQLite. PRAGMA statements can be issued in a similar manner to regular SQL statements. PRAGMA commands may alter the internal state of the database engine, and can influence the

Function-style PRAGMA calls (for example, PRAGMA table_info('table_name') ) and the SQLite-compatible PRAGMA t...ng schemas, DuckDB generates “did you mean...” style error messages. When there are thousands of attached databases, these errors can take a long time to generate. To limit the number of schemas DuckDB looks through, use the catalog_error_max_schemas o...in the same directory as the database file. To change this, use: SET temp_directory = '/path/to/temp_dir.tmp/'; Returning Errors as JSON The errors_as_json option can be set to obtain error information in raw JSON format.
