columnStandardTable

Last updated: August 12, 2026

Nested element for defining columns within createStandardTable.

This is a separate element from Liquibase column - it uses its own XSD definition to include Snowflake-specific features while excluding unsupported core attributes.

Supported attributes

From core column

Attribute	Type	Description
`name`	String	Column name (required)
`type`	String	Snowflake data type
`nullable`	Boolean	Whether column allows NULL (default: true)
`computed`	Boolean	Whether value is computed
`remarks`	String	Column comment
`defaultValue`	String	Default string value
`defaultValueNumeric`	String	Default numeric value
`defaultValueBoolean`	Boolean	Default boolean value
`defaultValueDate`	String	Default date value (ISO format)
`defaultValueComputed`	String	Default computed expression
`defaultValueSequenceNext`	String	Sequence NEXTVAL as default
`defaultValueSequenceCurrent`	String	Sequence CURRVAL as default
`defaultValueConstraintName`	String	Name for default value constraint
`autoIncrement`	Boolean	Enable autoincrement
`startWith`	Long	Starting value for autoincrement
`incrementBy`	Long	Increment step for autoincrement
`generationType`	String	Generation type for auto-increment
`defaultOnNull`	Boolean	Generate value when NULL is inserted

Snowflake-specific

Attribute	Type	Description
`autoIncrementOrder`	String	Sequence ordering: `ORDER` or `NOORDER`*
`collation`	String	Column collation (e.g., `en-ci`)
`maskingPolicy`	String	Name of masking policy to apply
`maskingPolicyUsing`	String	Columns for USING clause in masking policy
`projectionPolicy`	String	Name of projection policy to apply

*Only valid when autoIncrement=true.

ORDER vs NOORDER behavior

Mode	Guarantees	Performance	Use case
`ORDER`	Values in strict sequential order	Reduced concurrency	Invoice numbers, audit sequences
`NOORDER`	Unique values, may have gaps	Better throughput	Log entries, event records

Unsupported core attributes

These core column attributes are not available:

Attribute	Reason
`afterColumn`	Snowflake doesn't support column positioning
`beforeColumn`	Snowflake doesn't support column positioning
`position`	Snowflake doesn't support column positioning
`value`	Use `defaultValue` instead (for table creation)
`valueNumeric`	Use `defaultValueNumeric` instead
`valueBoolean`	Use `defaultValueBoolean` instead
`valueDate`	Use `defaultValueDate` instead
`valueComputed`	Use `defaultValueComputed` instead
`valueBlobFile`	Not supported in table creation context
`valueClobFile`	Not supported in table creation context
`encoding`	Not applicable
`descending`	Not applicable (index-specific)

Nested elements

constraints

Extends core constraints with Snowflake-specific options.

Attribute	Type	Description
`enforced`	Boolean	Whether constraint is enforced (Snowflake-specific)
`rely`	Boolean	Whether optimizer relies on constraint (Snowflake-specific)
`onUpdateAction`	String	Foreign key update action: `CASCADE`, `RESTRICT`, etc.
`onDeleteAction`	String	Foreign key delete action: `CASCADE`, `SET NULL`, `SET DEFAULT`

tags

Column-level tags for metadata management (nested element in XML, array in JSON/YAML).
