SHOW CREATE PROJECTION

Note

This is a Preview feature.

Shows the CREATE PROJECTION statement that was used to create the projection.

Syntax

SHOW CREATE PROJECTION <projection_name> FOR TABLE [database_name.]<table_name>;

Arguments

projection_name

The name of the projection created in the CREATE PROJECTION command.

database_name

The database where the projection's base table is located. This argument is optional.

table_name

The name of the table the projection is created on.

Remarks

  • If SELECT * is used in the project list of your CREATE PROJECTION statement, the project list expands at CREATE PROJECTION time and SHOW CREATE PROJECTION lists out all the columns. Therefore, this expanded list does not change if the base table is altered to add new columns.

Example

The following example displays the output of SHOW CREATE PROJECTION.

CREATE PROJECTION IF NOT EXISTS lineitem_sort_shipdate
(SHARD KEY(l_orderkey), SORT KEY(l_shipdate))
AS SELECT l_shipdate, l_orderkey FROM lineitem;
SHOW CREATE PROJECTION lineitem_sort_shipdate FOR TABLE lineitem;
+------------------------+---------------------------------------------+
| Projection             | Create Projection                           |
+------------------------+---------------------------------------------+
| lineitem_sort_shipdate | CREATE PROJECTION `lineitem_sort_shipdate`( | 
|                        | SHARD KEY `__SHARDKEY` (`l_orderkey`),      |
|                        | SORT KEY `l_shipdate` (`l_shipdate`)        |
|                        |   ) AS SELECT   `l_shipdate`,  `l_orderkey` |
|                        |   FROM `lineitem`                           |   
+------------------------+---------------------------------------------+

Database names can be referenced in the SHOW CREATE PROJECTION command.
