mc table view create

The mc table view create command creates a new Iceberg view on a MinIO AIStor cluster.

Views are virtual tables defined by SQL queries. You can provide multiple SQL representations with different dialects for cross-engine compatibility.

Example

The following command creates a view named monthly_sales in the prod namespace of the analytics warehouse on the myaistor MinIO AIStor cluster:

mc table view create myaistor analytics prod monthly_sales --sql "SELECT * FROM sales WHERE month = 1"

Syntax

The command has the following syntax:

mc [GLOBALFLAGS] table view create            \
                 ALIAS                        \
                 WAREHOUSE                    \
                 NAMESPACE                    \
                 VIEW_NAME                    \
                 --sql "SQL"                  \
                 [--attr "key=value"]         \
                 [--ignore-existing]

Brackets [] indicate optional parameters.
Parameters sharing a line are mutually dependent.
Parameters separated using the pipe | operator are mutually exclusive.

Copy the example to a text editor and modify as-needed before running the command in the terminal/shell.

Parameters

ALIAS

Required

The alias of a MinIO AIStor cluster on which to create the view.

NAMESPACE

Required

The name of the namespace in which to create the view.

VIEW_NAME

Required

The name of the view to create.

WAREHOUSE

Required

The name of the warehouse containing the target namespace.

--sql

Required

The SQL query that defines the view. Can be specified multiple times with a dialect prefix for different query engines.

Use the format dialect:SQL to specify a dialect-specific SQL representation:

spark:SELECT ... for Spark SQL syntax
trino:SELECT ... for Trino SQL syntax

Without a dialect prefix, the SQL is treated as a generic representation.

--attr

Alias: -a

Optional

Add a custom property for the view in key=value format. You can specify multiple --attr parameters to add multiple properties.

--ignore-existing

Alias: -p

Optional

Do not return an error if a view with the specified name already exists.

Global flags

This command supports any of the global flags.

Examples

Create a simple view

Use mc table view create to create a view with a SQL query:

mc table view create myaistor analytics prod monthly_sales --sql "SELECT * FROM sales WHERE month = 1"

Create a view with a specific dialect

Use the dialect prefix to specify the SQL syntax:

mc table view create myaistor analytics prod monthly_sales --sql "spark:SELECT * FROM sales"

Create a view with multiple dialect-specific SQL representations

Specify multiple SQL representations for different query engines:

mc table view create myaistor analytics prod monthly_sales --sql "spark:SELECT * FROM sales" --sql "trino:SELECT * FROM sales"

Create a view with custom properties

Use the --attr flag to add custom properties:

mc table view create myaistor analytics prod monthly_sales --sql "SELECT * FROM sales" --attr owner=data-team --attr env=production
