§Implements

ColumnAlteringInterface

OperationNodeSource

§Constructors

new AlterTableColumnAlteringBuilder(props: AlterTableColumnAlteringBuilderProps)

§Methods

addColumn(columnName: string, dataType: DataTypeExpression, build?: ColumnDefinitionBuilderCallback): AlterTableColumnAlteringBuilder

See CreateTableBuilder.addColumn

alterColumn(column: string, alteration: AlterColumnBuilderCallback): AlterTableColumnAlteringBuilder

compile(): CompiledQuery

dropColumn(column: string): AlterTableColumnAlteringBuilder

execute(): Promise<void>

modifyColumn(columnName: string, dataType: DataTypeExpression, build?: ColumnDefinitionBuilderCallback): AlterTableColumnAlteringBuilder

Creates an alter table modify column query. The modify column statement is only implemeted by MySQL and oracle AFAIK. On other databases you should use the alterColumn method.

renameColumn(column: string, newColumn: string): AlterTableColumnAlteringBuilder

toOperationNode(): AlterTableNode
