}Expand description
A single column’s authoritative type metadata — the source of truth for
decoding (type + scale + precision), never row inspection.
Fields§
§name: StringColumn name.
column_type: StringSnowflake logical type (FIXED, REAL, TEXT, BOOLEAN, DATE,
TIME, TIMESTAMP_*, VARIANT, OBJECT, ARRAY, BINARY, …).
scale: Option<i32>Decimal scale (digits after the point) for FIXED/NUMBER.
precision: Option<i32>Total precision for FIXED/NUMBER.
nullable: boolWhether the column is nullable (distinct from the nullable query param).
length: Option<i64>Declared character length for TEXT-family columns.
byte_length: Option<i64>Declared byte length.
database: Option<String>Source database, when reported.
schema: Option<String>Source schema, when reported.
table: Option<String>Source table, when reported.
collation: Option<String>Collation specifier, when set.
