Options related to SQL parser

Fields

parse_float_as_decimal: bool

When set to true, SQL parser will parse float as decimal type

enable_ident_normalization: bool

When set to true, SQL parser will normalize ident (convert ident to lowercase when not quoted)

enable_options_value_normalization: bool

When set to true, SQL parser will normalize options value (convert value to lowercase). Note that this option is ignored and will be removed in the future. All case-insensitive values are normalized automatically.

dialect: String

Configure the SQL dialect used by DataFusion’s parser; supported values include: Generic, MySQL, PostgreSQL, Hive, SQLite, Snowflake, Redshift, MsSQL, ClickHouse, BigQuery, Ansi, DuckDB and Databricks.

support_varchar_with_length: bool

If true, permit lengths for VARCHAR such as VARCHAR(20), but ignore the length. If false, error if a VARCHAR with a length is specified. The Arrow type system does not have a notion of maximum string length and thus DataFusion can not enforce such limits.

collect_spans: bool

When set to true, the source locations relative to the original SQL query (i.e. Span) will be collected and recorded in the logical plan nodes.

recursion_limit: usize

Specifies the recursion depth limit when parsing complex SQL Queries

Trait Implementations

impl Clone for SqlParserOptions

fn clone(&self) -> SqlParserOptions

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ConfigField for SqlParserOptions

fn set(&mut self, key: &str, value: &str) -> Result<()>

fn visit<V: Visit>( &self, v: &mut V, key_prefix: &str, _description: &'static str, )

impl Debug for SqlParserOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SqlParserOptions

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for SqlParserOptions

fn eq(&self, other: &SqlParserOptions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
