Interface ColumnType

DatabaseTypeName returns the database system name of the column type. If an empty string is returned, then the driver type name is not supported. Consult your driver documentation for a list of driver data types. [ColumnType.Length] specifiers are not included. Common type names include "VARCHAR", "TEXT", "NVARCHAR", "DECIMAL", "BOOL", "INT", and "BIGINT".

DecimalSize returns the scale and precision of a decimal type. If not applicable or if not supported ok is false.

Length returns the column type length for variable length column types such as text and binary field types. If the type length is unbounded the value will be [math.MaxInt64] (any database limits will still apply). If the column type is not variable length, such as an int, or if not supported by the driver ok is false.

Name returns the name or alias of the column.

Nullable reports whether the column may be null. If a driver does not support this property ok will be false.

ScanType returns a Go type suitable for scanning into using [Rows.Scan]. If a driver does not support this property ScanType will return the type of an empty interface.
